Remarks on Odiomaris aff. pilosus from the Iouanga River and two other streams

A lot of specimens obtained belatedly in the course of our research poses a problem: collected in the Iouanga River on 17 November 2016 (see Fig. 10 ) (MNHN-IU- 2018-2999) and previously identified to Odiomaris pilosus , they split into two species: four males are certainly O. pilosus , but about twenty individuals of various sizes (a few males and a larger number of females) do not correspond either to this species or to Richerius marqueti gen. et sp. nov.; nor is it identifiable with Odiomaris estuarius . The same unidentified species was found in another stream of the North Province and is believed to inhabit another stream in the South Province ( Fig. 10 ) (manuscript in progress).
