Head glabrous except for a line of hairs that runs along gena behind the postocular
furrow; malar furrow very weak and slightly curved (Fig.
Cephalic lappets present but small and not extending across forehead; right postocular
peduncle well developed, similar in size to eyestalk or perhaps larger; right subocular tentacle not evident; neck lobes similar, each with 5 or 6 tentacles of varying size; epipodium posterior to neck lobes with 4 or 5 tentacles of varying sizes on each side, with an epipodial sense organ faintly discernable at base of larger ones.
Coloration.--Head predominantly olive green, with a large black triangle on the occiput, black postocular
stripe, small black markings on the gena and a black border along its ventral edge.
DESCRIPTION: Head: Clypeus (tylus) unarmed, apically globose, weakly raised, extending anteriorly to and laterally weakly higher than juga; juga unarmed; antennal segment I stout, thickest, slightly curved outward, attenuated at base, and shorter than maximum length of head; segments II and III slender, cylindrical, and IV fusiform and barely thickened; each antennal segment clothed with scattered, short, semidecument, silver, bristle-like setae; antennal segments I to III densely tuberculate; ocellar tubercle barely raised; postocular
tubercle protuberant; labial segment I short, reaching posterior half of head.
Vertebral scales smaller than (0) or larger than (1) scales of the first dorsal (VRS); interparietal spot absent (0), rudimentary (1), present (2) (IPS); postocular
stripe absent (0), rudimentary (1), present (2) (POS); ventrolateral stripe absent (0), present (1) (VLS) virtually barren land is not suitable habitat for Dendrolaphis tristis.

legnotus of northern Mesoamerica in having the postocular
series of scales juxtaposed to the suboculars (a single continuous series of postoculars
and suboculars in the four listed forms).
Carapace with front edge densely pigmented; ocular tubercle black, with a dark stripe from postocular
furrow to lateral ocelli, leaving an anterior depigmented triangle that only in very pigmented specimens is pigmented; lateral surface with dark reticulated pigment; with 2 posterolateral dark spots.
At 8.1 mm, the postocular
, parietal, nuchal, inferior post-temporal, supracleithral, superior opercular, preoperculars (with the exception of the 2nd anterior), and lst and 2nd inferior and 1st superior infraorbital spines were present (Table 3).
