Geophis bellus — WILSON & TOWNSEND 2007: 5
Geophis bellus — WALLACH et al. 2014: 300
|Distribution||Panama (Panamá), elevation 600–800 m|
Type locality: near community of Altos de Pacora (east of Cerro Jefe), Province of Panamá, central Panama. The type locality is a few km northeastward of the summit of Cerro
Jefe, upper Río Pacora drainage, at roughly 9°15’N, 79°22’W.
|Types||Holotype: KU 110703|
|Diagnosis||DIAGNOSIS: A small, slender member of the sieboldi group of Geophis distinguished from other members of the genus by the combination of (1) dorsal scales in 15 rows, smooth anteriorly but moderately keeled and striated on posterior part of body; (2) anterior temporal present or absent; (3) six supralabials; (4) eye small, going about 3.5–4 times into snout length; (5) dorsal and ventral surfaces uniformly dark (black in life) except for vivid white band across rear of head; and (6) hemipenis unicapitate, about one-fourth bilobed, nearly acalyculate, with calyces confined distally to lobes of the large capitulum. The overall color pattern alone distinguishes Geophis bellus from any other small colubrid in Panama. Other small Panamanian snakes having blackish or dark brown bodies, and heads partially or mostly white, are Enuliophis sclateri, Ninia atrata, and Tantilla albiceps—all of which have pale venters. See Comparisons for discussion and contrast with relevant congeners (including G. betaniensis, G. brachycephalus, G. nigroalbus, and G. talamancae) in MYERS (2003).|
