| Diagnosis | Diagnosis: Atractus nasutus is distinguished from all congeners by the following: 17/17/17 smooth dorsal scale rows; two postoculars; long loreal; 1+2 temporals; seven supralabials, third and fourth contacting orbit; seven infralabials, first four contacting chinshields; 12 maxillary teeth, lacking diastema; three or four gular scale rows; four preventrals; 130 ventrals in the single male; 23 subcaudals; reddish brown dorsum, except by a light occipital band; creamish brown venter; small body size (single male with 176 mm SVL); moderate tail size (13.1% SVL); slightly bilobed, semicapitate, and semicalyculate hemipenis (Table 1). Among all congeners, Atractus nasutus shares only with A. lasallei and A. lehmanni the following suite of characters: 17 dorsal scale rows; seven upper and lower labials, first four contacting chinshields; generally four preventrals; 23–28 subcaudals in males; small to moderate tail size; long, robust, and acuminate caudal spine; reddish brown dorsum, with a light occipital band or blotches; brown pigmentation on venter. Atractus nasutus differs from both by having a distinctly acuminate snout, 12 maxillary teeth, 130 ventrals, large and complete occipital band, and a semicalyculate hemipenis (vs. truncate snout and 7–9 maxillary teeth in both species; 154–167 ventrals in males of A. lasallei and 139–155 in males of A. lehmanni; no occipital band in A. lasallei and narrow and incomplete occipital band in A. lehmanni; bicalyculate hemipenis in both species). |
| Comment | |
| Etymology | Named after the Latin adjective ‘‘nasutus’’ meaning prominent snout region (5large-nosed). This word is used here in allusion to the acuminate snout of the new species. |
