Notarius armbrusteri - новый солоноватоводный сом из Колумбии
Abstract
Notarius armbrusteri n. sp. is described from specimens purchased in the fish market of
Buenaventura, Valle del Cauca, Colombia. The species is distinguished from other eastern Pacific
species of Notarius by the following combination of features: mouth small, width 11.1–11.8% SL;
eye large, diameter 4.3–4.9% SL; distance between anterior nostrils 6.1–6.9% SL, distance between
posterior nostrils 5.9–6.9% SL; short maxillary barbels, length 20.5–22.2% SL; and gill rakers on
first arch 3–4+8–9 (total 11–13). Based on mitochondrial evidence (cytochrome b and ATP
synthase 8/6, total 1937 base pairs), the new species is closely related to N. insculptus, from the
Pacific Panama. An updated key to identify the eight described species of Notarius from the eastern
Pacific is provided. (Zootaxa 1249: 47–59 (2006))
