DistributionW Honduras (915-1370 m elevation)

Type locality: Sierra de Merendon, west of San Pedro, Honduras, elevation 4500 ft.  
Reproductionovoviviparous 
TypesHolotype: FMNH 5066 
DiagnosisDiagnosis: A Celestus with well-developed limbs, two pairs of internasals, frontal not twice as long as broad, interparietal smaller than the parietals, caudal scales striated but not keeled, distal portion of the hind toes angularly bent and covered beneath with smooth lamellae, and with thirty-three scales around the body. It is allied in these characters to Celestus steindachneri, from which it differs in having three prefrontals in contact with the frontal. Description of type.-Habitus lacertiform, with well-developed limbs, though the limbs fail to meet when adpressed, by the length of the forearm; head small, snout depressed, flattened, with rounded canthus; tail stout and parallel-sided at base, reproduced distally, ear opening very small.
The large frontal shield is less than one and one-half times as long as broad; three prefrontals in contact with the frontal; two pairs of transversely elongate shields between the prefrontals and the rostral; five supraoculars, the first excluded from contact with the frontal, the second and third in contact with the frontal; five supraciliaries; two shields between the frontal and superior temporal separate the parietals from the supraoculars; interparietal smaller than the parietals, in contact with the frontal and occipital, the latter slightly broader than long, slightly broader than the interparietal; nasal in contact with the rostral, followed by two small superposed postnasals; these are succeeded by a small preloreal shield about as wide as high; anterior loreal much higher than long, in contact with the posterior internasal and lateral prefrontal; three more small shields lead to the crescentic subocular; eleven supralabials, the suture between the seventh and eighth shortest and below the eye; temporals 4 4. Thirty-three scales around the body, the ventrals smooth, the dorsals finely striated; seventeen transverse lamellae beneath the proximal part of the longest toe, six longer and smoother scales beneath the distal portion; reproduced part of tail with keeled scales. Olive green above, lighter on the sides, yellowish green beneath; small black spots on the back and sides. Measurements. Total length (tail reproduced) 150 mm.; tip of snout to anal cleft 80 mm.; fore limb 16 mm.; hind limb 24 mm.; tip of snout to posterior border of ear 14.5 mm. (Schmidt 1933) 
CommentSynonymy: The placement of this species in Diploglossus is based on phylogenetic data by Pyron et al. 2013.
