Threatened fishes of the world: Allotoca goslinei Smith and Miller, 1987 (Goodeidae)

Common Names: banded allotoca, tiro rayado (Sp.). Conservation status: Endangered (Williams et al. 1989). Identification: ML 50 mm, distinguished from congeners by 15 narrow vertical bars (Smith and Miller 1987). Illustration by S. Fink. Distribution: Two localities on Arroyo Potrero Grande, Ameca tributary, Jalisco, Mexico. Abundance: Likely extinct in nature: In 2000, A. goslinei was the dominant fish at the type locality (ca. 75% proportional abundance). We extensively sampled the tributary in 2005–2006 and found none. Habitat and ecology: Associated with plants in shallow pools; likely feeds on small arthropods based on the diet of its sister species (Dominguez-Dominguez et al. 2002; Doadrio and Dominguez-Dominguez 2004; Webb et al. 2004). Cohabitates with natives: Allodontichthys polylepis, Poeciliopsis infans, Scartomyzon austrinus, Ilyodon furcidens (Wischnath 1993). Reproduction: Livebearer; sexual dimorphism in fin placement and coloration (Smith and Miller 1987). In captivity, sexual maturity reached within 3 months; broods of Environ Biol Fish (2009) 84:197–198 DOI 10.1007/s10641-008-9406-y
