NEW PRAESTOCHRYSIS AND NOTES ON DESCRIBED SPECIES FROM THE ORIENTAL REGION
(HYMENOPTERA, CHRYSIDIDAE)*
BY R. M. BOHART, DEPARTMENT OF ENTOMOLOGY University of California, Davis, CA 95616 The genus Praestochrysis Linsenmaier is distinguished by having 5 distinct teeth on tergum 111 and a rather stout antenna. In any case the latter has flagellomere I less than 3 times as long as broad. Bohart (1986, Insecta Mundi 1:148-154) gave a key to species of the Ethiopian Region. One additional species, lamborni, is here des- cribed from that region. It keys out to couplet 6 in the 1986 paper but differs in having no transverse frontal carina. Abbreviations used in the following descriptions are: F-I, etc., flagellomeres; TFC, transverse frontal carina; MOD, median ocel- lus diameter; T-I, etc., terga; S-11, sternum. Praestochrysis lamborni Bohart, new species Male holotype: Length 7.5 mm. Body moderately stout, green, midscutum mostly purple, F-1-11 green in front, wings weakly stained. Punctures moderately small and close. Head 1.25X as broad as long (fig. 2a); F-I 1.7X as long as broad (fig. 2d), F-I1 as broad as long, F-V twice as broad as long; scapal basin short and broad, polished above and in middle one-third below, rest punctate, frons 1.8X as broad at malar space as at its least width; TFC absent, midocellus lidded, malar and subantennal spaces each about 1 MOD; pronotum about as long as scutellum, median groove weak; metanotum rounded (fig. 2c); mesopleuron edentate, scrobal and episternal sulci distinct; propodeal projection sharp, incurved behind; T-I1 without midcarina; T-111 evenly convex before weakly developed pit row, lateral margin a little convex, 5 short, sharp distal teeth (fig. 2b); S-I1 spots small, triangular, nearly touching (fig. 2e).
Female. About as in male. T-I11 lateral margin slightly angled out, submedian teeth twice as long as others (fig. 2b). *Manuscript received by the editor March 3. 1987. Pu&e Ìö4:45-S (1987). hup Ytpsychu rinclub orgÌö4f94-04 html

Holotype male, Malawi: Mangoche (Fort Johnston), 1-14-34, emerged from flat moth cocoon on tree bark (W. A. Lamborn, OXFORD). Paratypes, 11 males, 29 females, same data as holotype (Oxford Museum, Bohart Museum); 3 males, 4 females, Malawi: Mzeze, 45 mi n. Mangoche, emerged from flat moth cocoons on tree bark (W. A. Lamborn, Oxford Museum, Bohart Museum, other major museums).
Discussion. The rounded metanotum, 5 distal teeth on T-111, and broadened flagellum are characters found also in micrornorpha Mocsary and africanum Buysson. However, both of these species have a definite TFC. In addition the micromorpha F-I is only 1.4X as long as broad instead of 1.7 as in lamborni. Also, in africanum the malar space is more than 2 MOD instead of only 1 MOD, and the lateral margin of T-I11 is not at all bent outward. The species is named for W. A. Lamborn, who collected the long type series. Praestochrysis luzonae Bohart, new species Male holotype: Length 7.5 mm. Body stout, green; deep purple across vertex, on scutum, and at base of T-111; T-I11 mostly bluish; F-I green in front; wings brown. Punctures coarse, close on vertex, widely separated by 4 smooth swellings on pronotum (fig. 3f), mostly a puncture diameter apart on rest of notum and terga. Head 1.55X as broad as long (fig. 3a), with prominent rugosities on vertex near eyes; F-I about twice as long as broad (fig. 3d), F-V 1.4X as broad as long; scapal basin short and broad, rather closely punctate; TFC broadly M-like (fig. 3a), branching above to nearly enclose midocellus and form a lid behind it; malar space 2.1 MOD; suban- tennal space 1 MOD; pronotum as long as scutellum, no median groove; metanotum with a flat, subtriangular mucro (fig. 3c); meso- pleuron edentate but with prominent carinae below large scrobal sulcus, episternal sulcus deep and punctate; propodeal projection large, acute, slightly convex behind; T-I1 without midcarina; T-I11 evenly convex before weakly developed pit row (fig. 3b), pits unev- enly shaped, mostly broader than long, lateral margin of I11 nearly straight, 5 sharp distal teeth, outer pair shortest; S-I1 spots rounded, touching (fig. 3e).
Female. Unknown.
Holotype male, Philippines: Luzon, Los Banos, IV-19-60 (A. Ojamin; U. S. National Museum, Washington).

Discussion. The 4 large and polished pronotal convexities are distinctive. Also, the rough projections behind the eyes have not been seen in any other Praestochrysis.
Praetochrysis spinula Bohart, new species. Holotype male. Length 7 mm. Body stout, blue green with exten- sive dark purple on vertex, notum, and terga, F-I green in front, wings light brown. Punctures medium coarse and fairly close on vertex and notum, coarse and separated by about a puncture diame- ter on terga. Head 1.5X as broad as long (fig. la); F-I 2. IX as long as broad (fig. Id), F-V 1.4X as broad as long; scapal basin rather finely punctate, punctures arranged in a somewhat crossridged pat- tern; TFC prominent, nearly straight, downturned laterally (fig. 1 a), backward branches weak, midocellus not lidded; malar space 2.5 MOD; subantennal space 0.8 MOD; pronotum as long as scutellum, no median groove; metanotum with a subtriangular, distally rounded, dorsally flattened mucro (fig. lc); mesopleuron with a well-formed scrobal sulcus, areolate below, episternal sulcus dis- cernible but weak; propodeal projection stout, sharply pointed, evenly convex behind; T-I1 without a midcarina; T-I11 rather evenly and strongly convex, pit row obsolete, lateral margin of I11 a little convex, 5 sharp and slender teeth, outer pair shortest (fig. lb); S-I1 spots rounded, touching (fig. le).
Female. Unknown.
Holotype male, Sri Lanka (DAVIS).
Discussion. The long T-I11 teeth, obsolete pit row, medially straight TFC, and flattened mucro distinguish this species. The Taiwanese basilacuna Sugihara has similar T-I11 teeth but the pit row is better developed, TFC is medially incised, and the metanotal mucro is longitudinally furrowed. Also, it is a larger species, 9-13.5 mm long.
Notes on Oriental Praestochrysis
While studying Oriental Praestochrysis, I have noted several characters of key value. The presence or absence of a metanotal projection is a prime distinguishing feature. A large such projection is often present in Praestochrysis (figs. 1, 3, 4, 5) as in basilacuna -

(Sugihara), crassiscuta (Mocshry), furnipennis (Smith), lachesis (Mocshry), luzonae Bohart, palawanensis (Mocshry), ribbei (Moc- shy), sarawakensis (Mocshry), shanghaiensis (Smith), spectabilis (Mocshry), and spinula Bohart. On the other hand, several species have little or no metanotal projection (figs. 6, 7). These are amo- enula (Mocshry), furcifera (Bingham), libita (Buy sson), and lusca (Fabricius). Other characters are the presence of 2 large mesopleural teeth (crassiscuta and spectabilis), a strong sublateral pronotal car- ina (lusca), pronotum with 4 smooth humps (luzonae), F-1 hardly longer than the pedicel (lachesis), and T-I11 teeth unusually long (basilacuna, spinula).
Three new species of the chrysidid genus, Praestochrysis, are de- scribed and figured: larnborni from Malawi, luzonae from the Phil- ippines, and spinula from Sri Lanka. Notes are given on previously named species from the Oriental Region.
