A KEY TO THE SPECIES OF SPINTHARINA WITH DESCRIPTIONS OF NEW SPECIES AND INDICATION OF SPECIES GROUPS ( HYMENOPTERA , CHRYSIDIDAE )

Spintharina Semenov (type species: vagans Radoszkowski occurs in the southern Palearctic and Ethiopian Regions. This group is characterized by the absence of teeth on tergum III, a long triangular forewing marginal cell, and an apically blunt or emarginate lateral propodeal projection. Fragmentary evidence points to Masaridae as hosts. I have been able to study types or authentically determined specimens of 23 of the 26 species. Status of the other 3 is in doubt. Complete synonymy and distribution will be given in a generic revision of Chrysididae now in preparation by L. S. Kimsey and R. M. Bohart. I would like to thank Dr. Kimsey for turning over to me her basic research on the genus, and for reviewing this paper. Technical terms used in the key and descriptions are" F-I etc., flagellomeres; T-I etc., terga; S-I etc., sterna; MOD, midocellus diameter. Type material has been studied at or borrowed from most of the important European and South African Museums. Acknowledgements will be made in the aforementioned revision.

Female.As in male but F-I 1.6 as long as broad, 1.2 as long as II or III.
Discussion.The continuous whitish distal margin of T-III and the short male F-I-II place dubai in the vagans group.
Spintharina senegalae Bohart, new species Holotype female.Length 5.5 mm.Bright green, terga extensively coppery to red, apical rim of T-Ill whitish translucent, tarsi light brown, legs otherwise green, wings nearly clear; scapal basin silvery pubescent in lateral third, medially punctate and crossridged (fig.9); punctation otherwise moderate and close but weak on clypeus and absent on T-Ill postpit; F-I 1.5X as long as broad, slightly longer than pedicel, F-II or F-Ill; malar space 1.7 MOD, subantennal space 1.3 MOD; TFC sharp; weakly parenthesis-like; midocellar area slightly depressed; mesopleuron with 3 angles or teeth below polished scrobal sulcus; propodeal projection truncate and apex a little emarginate; T-Ill convex basolaterally, pit row distinctly impressed, pits slightly elongate, apical rim convex; S-II spots rounded, separated by nearly 2 MOD.
Discussion.The continuous whitish translucent margin of T-Ill places senegalae in the vagans group.The green and coppery-red terga separate it from dubai.Spintharina sugdeni Bohart, new species Holotype male.Length 6 mm.Stout; head, thorax and sterna bright green, terga coppery with a greenish tint, tarsi pale brownish, legs otherwise green, wings nearly clear; scapal basin all silver pilose except a narrow median line of punctation and crossridging; punc- tation moderate and rather close but small on clypeus and absent on T-Ill postpit, forefemur well punctate above a ventral ridge; F-I Psyche [Vol. 941.4)< as long as broad, a little longer than pedicel or F-II, slightly shorter than F-Ill (fig.5); malar space 1.5 MOD, subantennal space 1.7 MOD; TFC sharp and broadly M-shaped; midocellar area depressed and weakly delimited; mesopleuron tridentate below areolate scrobal sulcus; propodeal projection stout, truncate; T-Ill with an angular basolateral projection (fig.5), pit row weakly impressed, pits long oval; apical rim convex; S-II spots nearly confluent.
Female.As in male.F-I about 1.5 as long as broad, slightly longer than pedicel, F-II or III; F-II very slightly shorter than F-III.
Discussion.The prominent basolateral swelling and concolor- ous T-Ill place sugdeni in the versicolor group, where it is distinct in having the subantennal space longer than the malar space.The species is named for Evan Sugden, who collected a large number of Chrysididae in Dubai.
Spintharina edneyi Bohart, new name Chrysis (Gonochrysis)rubescens Edney 1952: 446.Holotype male, "Springbok, Namaqualand," South African (South African Museum, Capetown).Nec Radoskowski 1880.I have seen the type which is a Spintharina in the innesi group.In addition to the relatively long malar space the flagellum is some- what nodose and bicolored (fig.2).The scapal basin is plainly microridged in the middle third.T-Ill is broad with a slight apicomedial indentation.The new name is given in honor of E. B.
Edney, who published extensively on South African Chrysididae.Spintharina postpunctata Bohart, new species Holotype female.Length 5.5 mm.Bright reddish coppery with tinges of green on scutellum and metanotum, sterna green and coppery, wings lightly stained; scapal basin lightly silver setose on outer fourth, middle half epunctate and microridged; other puncta- tion moderate, slightly separated, continued evenly to apex of T-Ill; F-I 2.5X as long as broad, nearly twice as long as pedicel, F-II or III; malar space 1.0 MOD; subantennal space 1.4 MOD; TFC irreg- ular, midocellar area depressed, limited below; mesopleuron tri- dentate below areolate scrobal sulcus; propodeal projection with a slanting apical truncation (fig.6); T-II and III weakly ridged at middle; T-Ill with a low basolateral convexity, pit row hardly indented, pits nearly obsolete, postpit area well punctured (fig.6), apical rim convex; S-II spots weakly defined, well separated.
Discussion.The short malar space, unbanded tibiae, and dis- crete microridging of the scapal basin place postpunctata in the pleuralis group.As in polychroma, the face is all coppery, but the nearly obsolete pit row, well punctate postpit area (fig.6), and all coppery terga are distinguishing.Spintharina kimseyae Bohart, new species Holotype female.Length 6 mm.Head and thorax green, terga purple, sterna brown and purple, legs purple to green, wings faintly stained; pubescence pale, inconspicuous; punctation moderately coarse, less so on head, outer fourth of scapal basin finely punctate, middle half microridged (fig.1); F-I 2.9 as long as broad, nearly twice as long as pedicel, F-I or II; malar space 1.1 MOD; subanten- nal space 1.7 MOD; TFC broadly M-shaped, not strong; midocellar area weakly depressed, hardly limited; mesopleuron tridentate below coarsely punctate scrobal sulcus; propodeal projection emar- ginate truncate (fig.1).T-Ill straight basolaterally, pit row well indented, pits large and nearly round, apical rim slightly angled but rounded at tip (fig.1); S-II spots slightly separated, not clearly defined.
Discussion.The short malar space, unbanded tibiae, and micro- ridged middle half of the scapal basin place kimseyae in the pleuralis group.The T-Ill roundly pointed shape is much like that ofpleura- lis and polychroma, both of which have the thorax bicolored copper and green instead of green and a little purple as in kimseyae.The species is named for Lynn Kimsey, who has contributed a great deal to our knowledge of Chrysididae.
