Remarks. The species was described based on four specimens collected by Ch. Alluaud. We were not able to examine type specimens, but had one specimen available from the type locality, Assinie, that fits the original description very well. This specimen, based on the shape of rostrum, well developed epistome and scrobes laterally curved downwards and not touching the ventral border of the eye, flat eyes and short antennal scapes, is clearly congeneric with Ascopus pyriformis and must be transferred to that genus as A. curvipes ( Hustache, 1931) , comb. nov. Here we create a valid species, extremely similar to A. echinatus , separable according to characters stated below in the key.
