Diagnosis | Diagnosis (genus and species): A depressed, short tail (tail length < snout-vent length), with enlarged spiny scales dorsally and lat- erally is unique to Hoplocercus among hoplocercines. Moreover, Hoplocercus differs from Enyalioides and Morunasaurus (character states in parentheses) in having the anterior opening of the Vidian canal on the ventral surface of the parabasisphenoid (anterior surface of the parabasisphenoid [dorsum sella] lateral to the sella turcica; Wiens & Etheridge 2003); a non-autotomic tail (autotomic; Etheridge 1967); slender and rounded sacral diapophy- ses (robust and flattened; Wiens & Etheridge 2003); and transverse processes of caudal vertebrae increasing in length from first to fourth caudal vertebra (decreasing in length throughout column; Wiens & Etheridge 2003). Hoplocercus can be further distinguished from Morunasaurus by having a parietal eye (Etheridge and de Queiroz (in Estes & Pregill, 1988), TORRES-CARVAJAL & DE QUEIROZ 2011] |
