Description: Nanobagrus immaculatus, is described from the Kahayan River drainage in southern Borneo. It is most readily distinguished from congeners in having a uniformly dark-coloured body lacking pale spots or patches (vs. pale spots or patches always present), larger eye (16.7–18.2% HL vs. 9.0–16.1), and a longer adipose-fin base (24.9–26.6% SL vs. 12.8–21.6). The synapomorphies used to diagnose Nanobagrus are reviewed and re-examined. Pseudomystus fuscus is hypothesized to be more closely related to Nanobagrus than to all other Pseudomystus and is hereby reassigned to the former genus. Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal soft rays: 11 - 13; Vertebrae: 34 - 35.; eye diameter 16.7-18.2% HL and adipose-fin base length 24.9-26.6% SL. Colouration: Body uniformly dark, lacking pale spots or patches. Etymology: The genus name Nanobagrus: Latin, nannus = small + Mozarabic bagre, Greek pagros = a fish, Dentex sp. The specific name immaculatus: derived from the Latin adjective, immaculatus, meaning unspotted or unstained, in allusion to the colouration pattern of the species, lacking dots or spots. |
