Remarks
de Mazancourt et al. (2018c) recently designated a lectotype for C. brevidactyla Roux, 1919 and redescribed it in detail. This species is now known from Indonesia (Aru Island, Halmahera), Papua New Guinea (New Britain), Solomon Islands (Choiseul, Kolombangara, Vella Lavella, Isabel), Vanuatu (Efate, Epi, Malekula and Santo), New Caledonia and Fiji. This species is encountered in the lower part of rivers, sometimes in brackish conditions near the estuary.
