Described
from specimens collected from the Zhujiang (Pearl River) basin,
southern China. It closely resembles Tachysurus
adiposalis and
Tachysurus ussuriensis, but differs in
having a large elliptical eye (19.8–24.4% HL), a short maxillary
barbel not reaching the posterior margin of the eye, a lightly serrated
posterior edge on the second dorsal spine, a caudal fin slightly
emarginated with upper lobe slighter longer than lower lobe, frontal
concave with a smooth surface, and supraoccipital process short
(far from the first basal bone of the dorsal spine). Inhabits medium
to large rivers in lowland areas with rocky substrate and moderate
or fast current. Valid in some literature as Pseudobagrus
gracilis. The Pelteobagrus
genera have in the past been distinguished by their forked caudal
fins (vs. truncate/emarginate caudal fins in Pseudobagrus
but most
of these genera have now been moved to a new family,
Tachysurus (Bogutskaya et al. 2008). |
