Hydrochus elsjeae Makhan 1994: 40  

Hydrochus obscurus Sharp   ; Oliva (1996), incorrect synonymy by Oliva

Originally described from Bolivia, based on one male. Only the holotype has been examined in this study   .

Remarks. I have examined the holotype of H. elsjeae Makhan   , including the male genitalia (ZMHB). Oliva (1996) synonymized H. elsjeae Makhan   with H. obscurus Sharp. However   , this is undoubtedly incorrect as the male genitalia of the two markedly differ. Among the most obvious differences is that the male genitalia of H. elsjeae   has large pseudoparameres, whereas H. obscurus   lacks pseudoparameres. Labels on the holotype of H. elsjeae   are: “Bo-
