I-- NEW GENERA AND SPECIES OF NEOTROPICAL AMISEGINAE ( HYMENOPTERA , CHRYSIDIDAE ) * BY

The Canadian National Collection (OTTAWA) has one of the largest, if not the largest collection of neotropical Amiseginae in the world. In a sample of about 700 unidentified specimens sent to me by Lubomir Masner from this collection there were many new taxa, including representatives of a new genus. In addition, material was borrowed from the Museum of Comparative Zoology, Harvard University (J. M. Carpenter), Cambridge, Massachusetts, the American Entomological Institute, Gainesville, Florida (H. Townes, GAINESVILLE), and the U.S. National Museum, Washington, D.C. (K. V. Krombein, WASHINGTON). The new species of Adelphe are described separately (Kimsey 1986). The remaining new taxa are included below. The following abbreviations are used: F flagellomere, MOD midocellus diameter, PD puncture diameter and Tgastral tergum.

Scape dark brown, malar space 1.0-1.Scutal posterolateral corners not projecting, wings evenly brown-stained 25 25.Propodeal posterior enclosures smooth, scapal basin distinct with few scattered punctures and without distinct transverse striation, pronotum and scutum with large circular punctures and without striae, notauli deeply impressed mocsaryi Ducke Propodeal posterior enclosures rugose or striate at least dor- sally, scapal basin not clearly delimited and densely striate, pronotal and scutal punctures striatiform among transverse striate 26 26. Face and thoracic dorsum covered with dense, linear, transverse striae, punctures tiny and 2-5 PD apart; scape reddish, paler than flagellum striata Kimsey Face and thoracic dorsum with coarse, irregular, transverse striae, punctures medium-sized and nearly contiguous; scape 32.Thoracic dorsum green, pronotum with transverse striae medially, forewings with unstained medial band belizensis Kimsey Thoracic dorsum blue, pronotum without transverse striae medially, forewings evenly brown-stained 33 33.Mesopleuron impunctate, or with few tiny punctures imme- diately below subalar fovea; F-I parallel-sided and 4X as long as broad bennetti Kimsey Mesopleuron punctate immediately below subalar fovea, punc- tures subequal in size to those on anterior half; F-I dilated and 3.5>( as long as broad 34 34.Hindtibia and tarsus reddish, paler than femur tenebrae Kimsey Hindtibia and tarsus dark brown, concolorous with femur rufi'lateralis Kimsey Amisega species are characterized by: narrow metanotum, less than half as long as scutellum; malar space less than one-eighth eye height; underside of head with long narrow fovea on either side of midline of genal bridge (-suboral fovea); propodeum without lat- eral angles; mesopleuron without oblique mesopleural carina, and pronotum without medial groove or anterior and lateral carina.
Species distinctions in this group are difficult, and color patterns tend to be more useful than structural measurements.Unfortunately, unlike most chrysidids, male Amisega tend to be structurally Psyche [Vol. 94  conservative and have few color differences between species.
Because of this difficulty with males, holotypes of most of the fol- lowing new species are females.Amisega belizensis Kimsey, new species Holotype female.Body length 3.5 mm.Face with fine striatiform punctures, scapal basin densely cross-ridged; malar space 1.3 MOD; eye in lateral view widest at midline; postocellar area covered with fine transverse striae and punctures; F-I 4>( as long as broad; F-II length 2.5 breadth; pronotum and scutum covered with striatiform punctures, with transverse striae on pronotum; scutum without notauli; scutellar punctures irregularly spaced 0.2-2.0PD apart, faintly striatiform anteriorly; mesopleuron with punctures densely clumped on anterior half, posterior area smooth and impunctate; propodeal enclosures smooth and impunctate; T-I and Ill-IV nearly impunctate, except for a few widely scattered tiny punctures; T-II with small anteromedial patch of tiny punctures, otherwise im- punctate.Head, pronotum, scutum, scutellum and metanotum coppery; rest of thorax and propodeum with faint blue-green tint; terga black, except T-I-II with a lateral bluish spot; antenna dark brown; legs, including coxae, red, except posterior half of hind- femur dark brown; wings brown-stained with unstained medial stripe across wing at stigma.
Male.Same as female, except wing color fainter, body with green tints, coxae and femora dark brown, and tibiae and tarsomeres red.
Holotype femalewBELIZE: Middlesex, 125m, 15 April 165, E. C. Welling (OTTAWA).Paratypes: female and 2 males, same data as type except 27 April 1965, 3 April 1965 and 15 March 1965.Discussion.The female of belizensis can be readily distinguished by the pale legs, coppery head and thorax and banded wings.Males are more difficult to distinguish but their legs tend to be pale api- cally, the notauli are essentially absent and the mesopleural puncta- tion is distinctive.Amisega bennetti Kimsey, new species Holotype female.Body length 3 mm.Face with fine contiguous punctures; scapal basin cross-ridged with scattered punctures; malar space 1.2 MOD; eye in lateral view widest at midline; F-I length 4)< breadth; F-II length 2)< breadth; postocellar area finely transversely striate, with scattered punctures 1-3 PD apart; pronotum, scutum and scutellum covered with fine transverse striae and small shallow punctures 1-3 PD apart; scutum with notauli present posteriorly and absent anteriorly; mesopleuron smooth with moderate punctures along anterior half, 0.2-1.0PD apart; propodeal enclosures smooth and impunctate; T-I with transverse band of small punc- tures along posterior margin; T-II with small punctures clumped anteromedially; T-Ill-IV with tiny punctures along posterior mar- gin.Face with green highlights; vertex coppery; thorax with bluish green highlights; abdomen dark brown without metallic highlights; antenna dark brown, except F-I yellow; legs including coxae yellow.

Holotype female--TRINIDAD, W. I., Curepe, Santa Margarita, 1-14 January 1974, E. D. Bennett (OTTAWA).Paratypes: 59 females and 302 males, same data as type except dates between January and December 1974 and 3 March 1961 (2 males), and male: Piarco, 27 February 1961.Discussion. A. bennetti and flavicrus are very similar and can be most readily separated by the color of the female antenna and legs.Otherwise bennetti can be distinguished by the evenly rounded pronotum, notauli indicated by a fine line; and the mesopleural punctation.Amisega bicolor Kimsey, new species Holotype female.Body length 3.5 mm.Scapal basin with smooth impunctate areas, without cross-ridging; frons to postocellar area appearing granular with contiguous small punctures and without striae; pronotum, scutum and scutellum same as vertex, without striae; malar space 1.5 MOD; eye in lateral view widest medially; F-I 4)< as long as broad; F-II length twice breadth; mesopleuron with dense nearly contiguous punctures on anterior two-thirds, posterior part smooth and largely impunctate; dorsal propodeal enclosures finely rugose; T-I with few very scattered punctures; T-II with small anteromedial clump of punctures.Head, scape and thoracic dorsum Am Amisega, An Anadelphe, Du Duckeia.brassy green; rest of thorax greener; pedicel and flagellum dark brown; legs, including coxae, yellow, except apex of hindfemur brown; terga black except I with anterior face reddish brown and posterolateral corners bluish.
Paratype females with cross-ridging in scapal basin and trans- verse striae on vertex.
Male.Same as female, except somewhat darker on T-I and II with more punctures.
Discussion.Of the species with pale legs bicolor most closely resembles striata, based on the sculpture of the mesopleuron and propodeal enclosures. A. bicolor can be distinguished by the bicol- ored hindfemur, the entirely dark scape and bluer thoracic color.Amisega chiapana Kimsey, new species H olotype female.Body length 3 mm.Face finely cross-ridged in scapal basin, with transversely striatiform punctures on frons and vertex; malar space 2 MOD; eye in lateral view widest at midline; postocellar area with fine transverse striae and punctures; F-I length 3.5X breadth; F-II length twice breadth; pronotum, scutum and scutellum with punctures striatiform; scutum with notauli only indi- cated faintly anteriorly; mesopleuron with dense punctures on ante- rior two-thirds, posterior third polished and impunctate above scrobe, rugose below; propodeal enclosures finely striate; T-I-II with very scattered punctures.Head and thorax with light green tints laterally; antenna dark brown, except scape yellow; coxae, trochanters and base of femora yellow, rest of foreleg yellowish brown, rest of mid and hindleg brown; wings brown stained.
Male.Same as female, except head and thorax blue-green, legs and antenna entirely dark brown, and T-II usually with small ante- romedial patch of punctures.
Discussion.This species belongs to the group that has dark legs even in the females.A. chiapana most closely resembles evansi based on the finely sculptured propodeal enclosures, densely punc- tate mesopleuron and obsolescent notauli.It can be distinguished Psyche [Vol. 94  from evansi by the long malar space and pale female scape and legs basally.

Discussion.A..17avicrus females are distinctly colored and can be immediately recognized by the brassy green head and thoracic color, and yellow legs and scape to F-Ill.Both sexes have a long narrow face and the pronotum appears slightly depressed sublaterally.
Males of flavicrus closely resemble those of bennetti but can be distinguished by the shape of the pronotum and the densely cross- striate face.Amisega flavipes Kimsey, new species Holotype female.Body length 3 mm.Scapal basin with dense transverse striae; vertex punctures touching to 2 PD apart; postocel- lar area without transverse striae except at posterior margin; malar space 1.5 MOD; F-I length 4>( breadth; F-II length 2.3)< breadth; pronotum coarsely transversely striate; scutum without notauli or transverse striae, scutellum without transverse striae; mesopleuron less than half punctate, posterior part smooth and impunctate; propodeal enclosures smooth; T-I with narrow transverse band of small punctures; T-II with anteromedial punctate area; T-Ill-IV with few minute punctures.Head and thorax, including propodeum blue; antenna dark brown, except scape paler beneath; legs includ- ing coxae yellow; terga blackish; wing membrane faintly brown- stained.

Holotype femalemBRAZIL: Bahia, Encruzilhada, November 1975, M. Alvarenga (GAINESVILLE).Paratypes--4 males and 8 females, same data as type, except some also collected by Seabra and Oliveira.Discussion. A. flavipes is one of the 3 South American species with yellow legs and dark antenna in the female.It can be distin- guished from perviridis and semiflava by the entirely yellow legs, black T-II, and the dorsum of the head without striation.Males can be recognized by the long malar space, purple T-II, dark legs and striate scapal basin.Amisega perviridis Kimsey, new species (Fig. 6) Holotype female.Body length 4 mm.Face appearing granular, with fine contiguous punctures; scapal basin with small triangular zone of fine cross-ridging; malar space 1.2 MOD; eye in lateral view Psyche [Vol. 94  widest below midline, strongly tapering dorsally (fig.6); F-I length 4X breadth; F-II length twice breadth; postocellar region covered with fine transverse striae, with scattered punctures 0.2-4 PD apart; pronotum covered with transverse striae; scutum and scutellum with sparser transverse striae, punctures 1-2 PD apart; notauli pres- ent posteriorly, obsolescent anteriorly; mesopleuron smooth with larger contiguous punctures along anterior half; propodeal enclo- sures smooth with scattered tiny punctures; T-I with narrow band of small punctures along posterior margin; T-II with dense small punc- tures anteromedially; T-Ill-IV with dense small punctures along posterior margin.Face brassy green with some coppery highlights around ocelli; thorax with green highlights becoming brassy dor- somedially; abdomen dark brown with blue highlights posterolaterally on T-I and medially on T-II; antenna dark brown; wings brown-tinted; legs including coxae yellow, except apical tarsomeres brown.
Male.Same as female except terga tend to be bluer.

Howden.
Discussion.This is another species from Trinidad.It can be dis- tinguished from bennetti and flavicrus by the larger size, broader head and entirely dark female antenna.Other diagnostic features of perviridis are the short malar space, pale legs in both sexes, scutum without transverse striae and mesopleuron with punctures on ante- rior half or less.Amisega rufilateralis Kimsey, new species Holotype female.Body length 4 mm.Face with small dense punc- tures, smooth between, scapal basin densely cross-ridged; malar space 1.3 MOD long; eye in lateral view widest below midline; postocellar area punctate without transverse striae; F-I length 4)< breadth; F-II length 2.5; pronotum, scutum, and scutellum punctate without striation; mesopleuron with anterior half punctate, posterior part smooth and impunctate; propodeal enclosures smooth and impunctate; terga with dense tiny punctures.Vertex, pronotum, scutum, scutellum and metanotum greyish blue; face and propodeum bright blue; T-I reddish basally, T-II reddish laterally, rest of abdomen black; antenna dark brown; fore and midfemora and hindleg dark brown, fore and midtibiae and tarsi red; wing membrane brown-stained.
Male.Same as female, except F-I length 3.5 breadth; head and thorax concolorous.
Holotype femalemBRAZIL: Guanabara, Repressa de Rio Grande, April 1966, M. Alvarenga (GAINESVILLE).Paratypes: male and 12 femalesmSanta Catarina, Nova Teutonia, various dates from January 1961 to March 1965, F. Plaumann; 6 femalesmsame data as type, except various dates from May 1966- June 1967.Discussion. A. rufilateralis most closely resembles aeniceps based on the dark legs, smooth propodeal enclosures and dorsum without transverse striae.Diagnostic characteristics include T-I black medially and reddish laterally, the suboral fossae nearly reach the occiput, and particularly in females the propodeum is much bluer than the rest of the thoracic dorsum.Amisega semiflava Kimsey, new species Holotype female.Body length 3.5 mm.Scapal basin with fine dense transverse striae; frons and ocellar area without striation; postocellar area sparsely striate, becoming dense along posterior margin; malar space 1.2 MOD; eye in lateral view widest slightly below midline; F-I length 3.8 breadth; F-II length twice breadth; pronotal punctures striatiform; scutum and scutellum without transverse striae; scutal notauli well-developed; mesopleuron with anterior half punctate, posterior part polished and impunctate; propodeal enclosures smooth; terga with sparse fine punctures.Head and thoracic dorsum dark greyish green; antenna blackish; legs including coxae yellow, except apex of femora and tarsorrleres dark brown; wings evenly brown-stained; terga black without metal- lic highlights. Male.Unknown.
Psyche [Vol. 94  Discussion.This is the only South American Amisega species with dark antennae, strongly bicolored legs, non-metallic abdomen and sparse transverse striation on the thorax.Amisega similis Kimsey, new species Holotype male.Body length 3 mm.Scapal basin with dense fine transverse striae; rest of head densely punctate without striation; malar space 1.3 MOD long; eye in lateral view widest below midline; F-I length 3.5X breadth; F-II length 2.2 breadth; pronotum, scu- tum and scutellum without striation; notauli complete; mesopleural anterior half punctate, posterior part smooth and impunctate; propodeal enclosures smooth; terga with dense small punctures; head and thoracic dorsum blue; terga dorsally bright blue; antenna dark brown; fore and midfemora and hindlegs dark brown, fore and mid tibiae and tarsi pale yellowish brown; wing membrane brown-stained. Female.Unknown.

Anadelphe Kimsey, new genus
Diagnosis.Malar space without vertical sulcus; occipital carina complete and well-developed; scapal basin flattened and smooth; flagellum short and fusiform in both sexes (figs.2, 3); male mandi- bles broad and flattened with 2 small apical teeth (fig.3); pronotum about as long as scutum, without medial groove or pit and without pit before lateral lobe; scutum with well-developed parapsides and deep notauli; mesopleuron with omaulus and without scrobal sul- cus; metanotum 0.7 as long as scutellum, with elevated medial area without differential sculpturing or punctation (fig.9); propo- deum with long dorsal surface evenly rounded to steep posterior declivity, laterally rounded; tarsal claws with slender medial tooth; hindcoxa without dorsobasal carina; both sexes fully winged; fore- wing (fig.8) RS extended by evenly curved dark streak, R1 0.5X as long as stigma or longer, medial vein arising before cu-a; terga rounded laterally.
Discussion.Anadelphe appears to be most similar to Adelphe based on the unusual male mandibles, complete occipital carina, long ocular setulae, thickened clypeal apex, dentate tarsal claws, and propodeum with long dorsal surface.However, the absence of a pronotal carina and scrobal sulcus and no lateral propodeal angles immediately distinguish Anadelphe from Adelphe.In addition, Anadelphe differs from all the other American amisegines due to the long metanotum and the malar space with an obsolescent vertical sulcus.
Discussion.The orange coloration and smooth sparsely punctate integument will distinguish alvarengai from simplifacies.Other diagnostic features of alvarengai are the short, broad face and broadly rounded clypeus.
Discussion.In simplifacies the face is longer and narrower than alvarengai and the clypeus is angulate medially.
Duckeia gracile Kimsey, new species (Fig. 1) Holotype female.Body length 3.5 mmo Face (fig.1), long and narrow, 0.9 as long as broad; scapal basin long and densely cross- ridged; midocellus MOD from ocular naargin; malar space 3.3 MOD; subantennal distance 0.4 MOD; genal flange small and short; occipital carina absent dorsally; facial punctures coarse and contiguous; eyes strongly converging dorsally; F-I length 2.9X breadth; F-II 1.3X as long as broad; pronotum 0.9>( as long as scutum, narrower than head; scutum with parapsides and notauli complete and well-developed, rotauli strongly converging posteo riorly; mesopleuron with small, simple scrobal pit and impunctate stripe along posterior margin; metanotum 0.4X as long as scutel- lum; thoracic dorsum with contiguous shallow punctures becoming smaller on scutum and scutellum, metanotal punctures contrast- ingly deeper and larger; forewing with brown spot across stigma and RS; propodeum with posterior surface coarsely rugose between carinae; abdominal punctures small, shallow and 0.5-1.0PD apart.Body dark brown, except head with blue tints, antenna dark brown; legs, including coxae dark brown becoming red on tarsi, mesopleu- ron with ventral and posterior reddish stripe and T-II with faint bluish tint on lateral margin.
Male.Same as female.
Discussion.The most distinctive features of this species are the slender compressed body, narrow-face, the faint metallic color and the weak abdominal punctation.These characteristics will imme- diately distinguish gracile from cyanea Costa Lima.
Duckeia vagabunda Kimsey, new species Holotype female.Body length 3.3 mm.Scapal basin long and densely cross-ridged; midocellus 2.5 MOD from ocular margin; malar space 4.3 MOD; subantennal distance 07 MOD; genal flange slightly shorter than eye height; occipital carina complete dorsally; facial punctures coarse and contiguous; F-I length 2.6 breadth, F-II 1.2 as long as broad; F-V length 0.9X breadth, pronotum 0.9 as long as scutum, about as broad as head posteriorly; scutum with parapsides clearly indicated and notauli faint; mesopleuron with small, simple scrobal pit and impunctate stripe along posterior margin; metanotum 0.4 as long as scutellum; thoracic dorsum with coarse contiguous punctures, becoming only slightly smaller on scutellum and metanotum, metanotal punctures deeper; forewirg with brown spot across stigma and RS; propodeal dorsal enclosures smooth and polished medially and evenly rugose along margins, posterior surface smooth with scattered punctures; abdominal punc- tures coarse, contiguous and subequal to thoracic punctures Body bright metallic blue, except antenna, legs and tegular dark brewn, becoming paler on tarsi. Male.Unknown.
Holotype female--MEXICO (WASHINGTON) reared from phasmatid egg on leaf of Chamaeodora oblongata from quaran- tined material arriving on airplane in Memphis, Tennessee, 27 March, 1962.Phasmatid egg probably that of Prisopus berosus Westwood according to label.Paratype female reared from phas- matid egg on palm leaf in quarantine material arriving in San Antonio, Texas, by airplane from Mexico.Discussion.Duckeia vagabunda most closely resembles cyanea, having a more robust body than gracileo It can be distinguished from gracile by the greater distance between the midocellus and eye, longer malar space and bright blue coloration.D. vagabunda differs from cyanea in having the eye encircled by a faint carina versus a pronounced one in cyanea, the female flagellomeres not lobulate and F-V not less than 0.9 breadth.The paratype female closely resembles the holotype except that the legs and scape are reddish.
