Remarks. Lelej (2005) treated Mutilla acidalia Cameron, 1897 as a synonym of M. villosa Fabricius, 1775, since the former was considered a variety of M. hexaops de Saussure, 1867 based on André (1899), which was synonymized with M. villosa by Lelej (2005). The late B. Petersen studied the type material of P. Cameron’s species described from the Oriental region, including syntypes of M. acidalia (pers. comm. to ASL), and regarded this species as a distinct species in the genus Trogaspidia . However, the male and female of T. acidalia sensu Petersen actually belongs to a new species, E. buddha sp. nov. We found among the specimens from Sri Lanka two females which correspond to the original description of M. acidalia . Thanks to Gavin Broad (BMNH), ASL studied the photos of the female lectotype, especially the pygidial plate (Fig. 14) and found it to be identical to said specimens. The male of M. acidalia associated by Cameron (1897) (not found in BMNH) with unmodified mesoscutellum probably belongs to the genus Krombeinidia Lelej, 1996 or Petersenidia Lelej, 1992 .
