REVISION OF LEUCOSPIDAE 197 



Very close to L. biguetina Jurine, but differs mainly in the following characters 

 in addition to those mentioned in the key above. 



Pale orange markings very extensive including scape (pedicellus and base of flagellum pale 

 reddish), whole of pronotum, scutellum (except axillae) and legs (except small black spots at 

 base of coxae), median quadrangle and broad sides of mesoscutum, upper mesepisternum, 

 metapleurum and most of first, fourth and fifth tergites and epipygium. Frontal protuberances 

 very weak. Premarginal carina on pronotum obliterated. Scutellum fairly convex. Pro- 

 podeum medially raised, median carina weak among coarse and very irregular alveolate sculpture 

 including several stronger rugae. Toothed margin of hind femur suggesting a lobe subapically 

 (Shestakov, 1923 : fig. 1; Nikolskaya, i960 : 201, fig. 126).

The PEDICULATA-Grovp 



Some species of this group have the small teeth behind the broad basal tooth of 

 hind femur extremely small and regular, in the form of a comb (Text-figs 225, 233). 

 One of these species, when described, was put in a separate genus, Epexoclaenoides 

 Girault (1915, with E. bicinctus Girault as type-species). Weld (1922 : 4, 35), 

 without actually knowing the type-species, accepted the genus as valid and described 

 in it another, rather aberrant species (pyri/ormis) and added its gastral characters 

 to the generic characteristics. However, with more species known, both the form 

 of the gaster and of the teeth on the hind femur proved useless for separating even 

 a species-group. For example, L. globigera sp. n. has almost identical form of 

 gaster as L. pyri/ormis (Text-figs 234, 235), but the teeth are irregular, not comb-like. 

 On the other hand they are minute and regular in L. pediculata, slightly irregular in 

 L. williamsi (Text-fig. 225) and quite irregular, as in most Leucospis species, in 

 L. micrura, L. bakeri and L. metadata (Text-figs 235, 236). 



The following characters of the species-group, partly also used in the key, may 

 be stressed. 



Genae short, strongly converging. Pronotum convex, premarginal carina always distinct, 

 short discal carina often so, though not angulately raised. Dorsellum at margin slightly to 

 distinctly carinate, shortly bidentate or bituberculate. Hind coxa without dorsal tooth, dorsal 

 edge even posteriorly rather broad, its sloping edge blunt or, rarely (L. micrura), subserrate. 

 Hind tibia apically subtruncate, outer spur conspicuous, not rudimentary. Gaster in both 

 sexes subpetiolate, distal part distinctly inflated, in female dorsally obliquely sloping, reflexed 

 ovipositor reaching at most near to base of fifth tergite, sometimes very short. 



The group seems to be most related to the dorsigera-group, at least on the pronotal, 

 dorsellar and hind leg characters, but differs mainly in the form of gaster and 

 apex of hind tibia. It is known only from the Indo-Australian region and includes 

 L. bakeri Crawford, L. maculata Weld, L. williamsi sp. n., L. calligastri (Ferriere), 

 L. pediculata Guerin-Meneville, L. giraulti nom. n. (— bicinctus Girault), 

 L. pyriformis (Weld), L. globigera sp. n. and L. micrura Schletterer.
