REVISION OF LEUCOSPIDAE 177 



scutellum, first tergite (in female) and hind femur are more or less broadly separated 

 (as for example in the type of L. feminina) or, in male, the spots on the first tergite 

 disappear while the two cross-bands on pronotum are still complete (type of similis), 

 or the reduction may reach a similar pattern as described for the Ceylonese 

 population. In one male from the Buru Island (Indonesia, Banda Sea) the yellow 

 is still more reduced than in those from eastern New Guinea, viz. to a mere short 

 and interrupted line anteriorly on pronotum and a tiny double spot on the 

 propodeum, otherwise the whole body is black. 



The different position of the spots on the first tergite in the males and females, 

 along with the slightly different colour of the wings, to some extent also with the 

 mostly whitish and more reduced markings on one side and the yellow and more 

 extended markings on the other, seemed to suggest that two species may be involved 

 (as already mentioned, petiolata and aruera). But I have not seen a male which 

 would fit the petiolata form and have the lateral spots on the first tergite, so common 

 in the females. Probably this is just a case of sexual dichroism. And I could 

 not find anything in the morphology that would really help. There is some variation 

 in the length of the malar space (mentioned elsewhere; relatively longer than in 

 L. sinensis Walker); the puncturation of the body, especially of the gaster may 

 be coarser or finer, sometimes relatively shallower on the mesoscutum of some 

 specimens; the pronotal cross-ribs may be well defined or lower and partly obliterated 

 by puncturation. However, I was unable to find any gaps in the variation of these 

 characters and, therefore, regard all the forms mentioned as belonging to one 

 variable species. 



Biology. No host records available. The wide distribution and variation of 

 L. petiolata may reflect different host bees or different 'model' wasps in different 

 regions. 



Distribution. Sri Lanka, India, Bangladesh, Burma, Thailand, S. China, 

 Philippines, Malaysia, Indonesia (but no record from Sumatra until now), New 

 Guinea, Queensland.
