|Diagnosis||Diagnosis. Alopoglossus meloi sp. nov. is distinguished from all other species in the genus Alopoglossus by the combination of the following characters: (1) scales on sides of neck keeled, imbricate (at least posterior ones phylloid); (2) four pairs of chin shields (well-developed fourth pair); (3) third pair of chin shields irregularly trapezoidal (heptagonal), separated from gulars by large scales; (4) scales on sides of neck in 6–8 transverse rows; (5) gulars smaller, but similar in shape to dorsals, pointed, imbricate, phylloid (except the first transverse row is smooth, almost rounded); (5) keeled temporal scales; (6) ventrals smooth to feebly keeled, mucronate and imbricate, with posterior margin bluntly pointed; (7) total number of femoral pores 20–23 in males.|
Comparisons with other species. Alopoglossus meloi sp. nov. differs from A. atriventris, A. buckleyi, A. copii, A. embera, A. festae, A. lehmanni, and A. viridiceps (in parenthesis) in having scales on sides of neck similar in shape to dorsals, nongranular, keeled, imbricate (granular in A. atriventris and A. buckleyi; mostly granular in A. embera, A. festae, A. lehmanni, and A. viridiceps; conical with apparent bare skin between conical scales in A. copii). It also differs from A. embera, A. festae, and A. viridiceps in having gulars not in two longitudinal rows (vs. a double longitudinal row of widened gular scales); from A. lehmanni in having dorsal scales rhomboidal, in oblique rows (vs. dorsal scales hexagonal with parallel lateral edges, in transverse rows). Alopoglossus meloi sp. nov. differs from A. angulatus (in parentheses) in having four pairs of chin shields (vs. three pairs), and third pair of chin shields irregularly trapezoidal, separated from gulars by large scales (vs. third pair of chin shields with rounded posterior margins, in direct contact with gulars or separated from them by a row of small, rounded or granular scales) (Fig. 3).
|Comment||Distribution: see map in RIBEIRO-JÚNIOR 2018: 33 (Fig. 5).|
Habitat: leaf litter, predominantly in a more open, dry forest, compared with typical Amazonian dense forest. MHNCI 13588 and 13950 were collected in lowland dense forest, near water.
|Etymology||The specific epithet is a noun in the genitive case honoring André Renato de Melo Teixeira, for his great contribution motivating and supporting the present study. I have a special debt of gratitude for his help, tenderness, and encouragement.|
