Diagnosis

Alopoglossus andeanus is distinguished from all other species of Alopoglossus by the combination of the following characters: (1) scales on the sides of the neck non-granular, keeled, imbricate (at least medial and posterior ones phylloid), in 11 or 12 transverse rows; (2) three pairs of chin shields; (3) third pair of chin shields with rounded posterior margins, in direct contact with gulars; (4) presence of a pair of medial enlarged pregular scales; (5) scales on gular region varying in shape and size: lateral ones strongly keeled, pointed, phylloid; anterior, medial and posterior ones varying from smooth to feebly keeled, bluntly pointed; medial and posterior ones larger than anterior and lateral ones; (6) ventral scales smooth, mucronate, imbricate, with bluntly pointed posterior margins; (7) total number of femoral pores in males 24–28.
