Abstract
Ongoing investigation of the interstitial communities of the River Rhône revealed the presence of a new species of Ameiridae Monard, 1927. Both sexes of Nitocrellopsis rouchi sp. n. are described herein. Re-examination of type-material (when available) of Nitocrellopsis ioneli (Dumont & Decraemer, 1974), N. petkovskii (Rouch, 1987), N. hippocratis (Cottarelli & Forniz, 1993) and N. hellenica (Cottarelli & Forniz, 1993) and other Nitocrella-related genera sensu Petkovski (1976), revealed differences in cephalic appendage morphology between species which are discussed together with the identification of some minute morphological characters observed for N. rouchi with the aid of scanning electron microscopy. A generic diagnosis is given, together with type-species designation to make available the generic name. A key to species of Nitocrellopsis gen. mov. is provided.
