|Distribution||S/C Guatemala, 2000-2100 m elevation|
Type locality: 3 km SSE Chichicastenango, 2100 m elevation, in valley between Paxot and Caminibal, Quiché, Guatemala.
|Types||Holotype: UTA R-18696, a 521 mm female (J.A. Campbell, 14 June 1987).|
|Diagnosis||Diagnosis. This species is a member of the veraepacis group of Adelphicos; this group differs from A. quadrivirgatus, the only other member of the genus, by possessing a pattern of broad lateral stripes, a well-developed third infralabial and unexpanded chinshields, and more numerous hemipenial spines (condition unknown in A. ibarrorum). Adelphicos ibarrorum may be distinguished from all members of the veraepacis group, except occasional individuals of A. nigrilatus, by its bright orange ground color, immaculate venter, and absence of vertebral or dorsoventral stripes (in most specimens of A. nigrilatus the vertebral and dorsolateral body stripes are present). Adelphicos ibarrorum further differs from A. nigrilatus in usually having more ventrals in females [135-138 (x = 137.0) and 123-135 (x = 127.7), respectively], in having the distance across the eye contained 2.9-3.2 (x = 3.0) times in the snout length (1.4-2.6, x = 2.0, in A. nigrilatus), in having seven palatine teeth (10-11 in A. nigrilatus), and in reaching a greater length (521 mm vs. a known maximum of 451 mm for A. nigrilatus). For further differences that clearly distinguish A. ibarrorum from other members of the veraepacis group, see Table 1 and Remarks (Campbell & Brodie 1988).|
