Adelphicos daryi — WALLACH et al. 2014: 9 

Type locality: San Jorge Muxbal, 1844 m elevation, 5.5 km W San José Pinula, Dpto. Guatemala, Guatemala.  
TypesHolotype: KU 187260, a 487 mm female (J.A. Campbell, 11 July 1980). 
DiagnosisDiagnosis: The new species is a member of the veraepacis group that can be distinguished from all other members of the group by its large size, females attain lengths of at least 574 mm and males probably exceed 400 mm; broad frontal plate, at least as broad as long; dorsal coloration dark brown suffused with black;
relatively small eye contained 2.7-3.2 times in the snout length; low number of dentary teeth, 8-9 (mode 9).
It usually may be distinguished from A. veraepacis and A. latifasciatus by its low number of ventrals, 120 in male, 128 132 in females, opposed to 120—133 and 128 in males, and 132—142 and 133-138 in females respectively. The male possesses 28 subcaudals, whereas males of A. veraepacis have 29-41 and A. latifasciatus have 46-51. The number of subcaudals, 19 22, distinguishes female A. daryi from A. veraepacis (24-31) and A. latifasciatus (37-41). The modal number of palatine teeth is 7 in A. daryi and 8 and 9 in A. nigrilatus and A. latifasciatus, respectively (Campbell & Ford 1982).
