Eotrogaspidia Lelej, 1996 Diagnosis. FEMALE. This genus has the procoxa armed with a tooth or smooth tubercle ( Fig. 118 ), the scutellar scale present; the propodeum broader than the pronotum; the T2 disc with two pale lateral spots; T3 and T4 each with pale setal bands; and the pygidium defined, but not striate or entirely rugose. MALE. See Lelej (1996c). Diversity and Distribution. Four Oriental species are recognized ( Lelej 2005 , Lelej & van Harten 2006 ), three are discussed below and one, E. ekka ( Nurse, 1902 ) , occurs in India . Remarks. By having flattened and setose metacoxae in the male, this genus is similar to Vanhartenidia Lelej in Lelej & van Harten, 2006 . In fact, one of the previously recognized Eotrogaspidia species, V. dives ( Smith, 1855 ) was transferred into Vanhartenidia ( Lelej & van Harten 2006 ) . An interesting similarity in females of these genera is that the procoxa is armed with a tooth in both genera, although various other trogaspidiine genera have a similar tooth, including Wallacidia and many species within Trogaspidia itself. In males, there are distinct genitalic differences between these genera and in females they can be separated by the coarsely sculpted pygidium of Vanhartenidia that has the lateral carina expanded apically ( Lelej & van Harten 2006 ), while Eotrogaspidia have weaker pygidium sculpture and lateral carina ( Figs 117, 121 ).
