Neblinichthys


Neblinichthys is a small genus of catfish (order Siluriformes) of the family Loricariidae. It includes two species, N. pilosus and N. yaravi.

Taxonomy

Neblinichthys was described by Ferraris, Isbrucker, and Nijssen in 1986. Neblinichthys is derived from the Latin nebula which means mist or vapor, and ichthys for fish.

It was found that Franz Steindachner's original description of Peckoltia yaravi matches that of Neblinichthys. This makes Neblinichthys yaravi the senior synonym of Neblinichthys roraima Provenzano et al. 1995.

Appearance and anatomy

Neblinichthys species are unique in that the breeding males have a snout brush formed by elongate, bristle-like odontodes pointing forwards on the snout. More fairly elongated odontodes are found on the top of the head and on the body. Otherwise they appear rather similar to Lasiancistrus species. Females and juveniles may be differentiated from Lasiancistrus species by the lack of cheek whiskers. Neblinichthys species also have their pectoral fin and pelvic fin spines the same length.

N. pilosus reaches a length of about 9 centimetres SL. N. yaravi reaches a length of about 5 cm SL.

Distribution and habitat

N. pilosus is distributed in the upper Negro, Casiquiare, and Baria River basins. N. yaravi is found in the Kukenan River basin in upper Caroni River drainage. Both species are from Venezuela. Neblinichthys are found in small creeks to medium-sized rivers at the base of tipuis. N. yaravi is found in creeks with a substratum of rocks, small stones, and fine sand, without aquatic vegetation.
