Etymology

The specific epithet is a noun in the genitive case honouring herpetologist Guarino Rinaldi Colli in recognition of his valuable contribution to the knowledge on the lizards of the Cerrado, especially in the State of Rondônia, Brazil.

Diagnosis

Alopoglossus collii 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 eight or nine transverse rows; (2) three pairs of chin shields; (3) third pair of chin shields with rounded posterior margins, in direct contact with gulars or separated from them by small scales; (4) absence of a pair of medial enlarged pregular scales (see Remarks below); (5) scales on gular region varying in shape and size: lateral ones strongly keeled, pointed, phylloid (except the anterior ones); the first three anterior transverse rows with scales smooth, almost rounded, larger than those in the proceeding row (anteriormost row with the largest scales); medial and posterior ones smooth, almost rounded, bluntly pointed, larger than lateral ones; (6) ventral scales mucronate, imbricate, with bluntly pointed posterior margins, varying from smooth to feebly keeled; (7) total number of femoral pores in males 19–22.
