REMARKS
Ethusa parapygmaea View in CoL is known only from the male holotype (MNHN-B 19092) and a second male specimen. It was described as being very close to E. pygmaea Alcock, 1894 View in CoL , the main difference being their G1. The most distinctive character of E. parapygmaea View in CoL is the foot-like shape of its G1 ( Chen 1993: fig. 12e). The G1 of a second specimen (MNHN-B 28555) were slightly thicker at the tip than those of the holotype, but their general shape was very similar. In E. pygmaea View in CoL the G1 have less slender, nearly triangular tips and a pointed prominence along each inner margin of the proximal portion of the tips ( Chen 1993: fig. 13f).
E. parapygmaea View in CoL is also close to E. indonesiensis Chen, 1997 View in CoL . Their differences are outlined in the discussion of E. indonesiensis View in CoL (see above).
