|Etymology||Rhyacoglanis, from the Greek rhyax = torrent + glanis = catfish; indicating a catfish inhabiting running waters in reference to the habitat of the genus. Gender masculine. The specific epithet seminiger, adjective from the Latin semi = half + niger = black, referring to the dramatically contrasting light vs. dark body color pattern.|
|Size||78mm or 3.1" SL. Find near, nearer or same sized spp.|
|Identification||Rhyacoglanis is distinguished from other Pseudopimelodidae by three synapomorphies: presence of a light blotch on the cheek; a connection between the middle of the dark caudal-fin stripe and the dark caudal-peduncle pigmentation; and 30-35 total vertebrae. A key to the species is located HERE. |
Rhyacoglanis seminiger differs from all congeners by having a fusion of the dark subdorsal and subadipose bands, creating a broad uniformly-dark area across most of the body (vs. distinct subdorsal and subadipose bands with a pale space separating them).
