Teleostei (teleosts) > Siluriformes (Catfishes) > Amblycipitidae (Torrent catfishes)
Etymology: Xiurenbagrus: Because of mister Ning Xiuren, Hangzhou, Institute of Oceanography; oceanographer and phytoplankton specialist; dorsalis: The specific epithet dorsalis is Latin for dorsal, alluding to the unique position of dorsal-fin origin of this species when compared with it congeners.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 12. Xiurenbagrus dorsalis can be diagnosed from its congeners by the following combination of characters: 7 dorsal-fin branched rays (vs. 6 in X. xiurenensis and X. gigas); pelvic-fin origin opposite base of fourth branched dorsal-fin ray (pelvic-fin insertion posterior to dorsal-fin base in X. xiurenensis and X. gigas); serrations absent on the posterior edge of pectoral-fin spine (vs. strong serrations present in X. xiurenensis and X. gigas); adipose fin confluent with caudal fin (vs. adipose fin posteriorly with a free flap and not confluent with caudal fin in X. xiurenensis and X. gigas); maxillary barbel longer than head length and reaching posterior tip of pectoral-fin (vs. maxillary barbel shorter than head length, reaching or slightly exceed pectoral-fin insertion in X. xiurenensis and X. gigas); eyes absent (vs. small eyes present in X. xiurenensis and X. gigas) (Ref. 96642).

Biology     Glossary (e.g. epibenthic)

Inhabits a very small underground stream with substrate of small rocks. The stream flows across the bottom of the well. A pump is connected to a 4 m depth well with plastic piping. The type specimen emerged through the water during pumping (Ref. 96642).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
