Omoadiphas cannula — WALLACH et al. 2014: 505 
DistributionHonduras (Sierra de Agalta, Olancho)

Type locality: Montaña de Peña Blanca, Sierra de Agalta, 4 km N of Catacamas, 14°53’26”N, 85°53’46”W, 1250 m elevation, departamento de Olancho, Honduras.  
TypesHolotype: UNAH 1740 (Universidad Autónoma de Honduras, Tegucigalpa), an adult male, collected 13 September 1989 by Gustavo A. Cruz. 
DiagnosisDiagnosis in MCCRANIE & CRUZ-DÍAZ 2010. 
CommentThe new species differs from O. aurula in number of subcaudal, supralabial, infralabial, and postocular scales, in color and pattern, and in having the posterior nasal scale in contact with the prefrontal scale. It differs from O. texiguatensis (known only from a subadult female) in having fewer subcaudals and the dark brown dorsolateral stripe involving all of scale rows two and three on each side of the body. 
EtymologyThe specific name cannula is formed from the Latin word canna (reed, cane) and Latin suffix –ulua (diminutive). The name refers to the Sierra de Agalta where this small snake was collected. The name Agalta is likely formed from the indigenous Pech language acatla (reed grass) and Tla (abundant).
