CommentDiagnosis.—Siagonodon acutirostris is distinguished from all Neotropical leptotyphlopids by the following unique com- bination of characters: snout slightly acuminate in lateral and ventral views; absence of supraocular scale; middorsal cephalic plates distinctively enlarged; ocular scale subhep- tagonal, dorsal apex acuminate and anterior border straight, roughly vertical at eye level; first and second supralabial scales not reaching eye level; two supralabials (1+1); fused caudals absent (Fig. 1B); temporal scale not distinct; rostral subcircular in dorsal view; middorsal scales 169–183; midventral scales 161–173; subcaudal scales 9–11; 12 scales around the middle of the tail; dorsum uniformly pale copper on five dorsal scale rows, contrasting with the whitish cream tonality covering nine scale rows of venter, and thereby reaching the paraventral region of trunk [PINTO & CURCIO 2011]. 
EtymologyEtymology.—The specific epithet acutirostris derives from the union of the Latin adjective acutus (= pointed) with the substantive rostrum (= beak, snout). This name is given in allusion to the slightly acuminate shape of the snout exhibited by the new species.
