|Distribution||Venezuela (Bolivar); elevation 400-1400 m.|
Type locality: Vegas Falls, 15 mi north of Esmeraldas, Venezuela, elevation 1400 m.
|Types||Holotype: AMNH R36649|
|Diagnosis||Diagnosis. Neusticurus with elongate snout, regular scales in frontonasal-prefrontal region, tympanum deeply recessed in the external auditory meatus, lower eyelid with semitransparent disc of 4 or 5 palpebrals. Dorsum with enlarged, keeled scales on midline and paravertebral zone without enlarged tubercles; flanks with keeled scales of equal size. Scales across sides and dorsum in three different rings (one posterior to the forelimbs, another at midbody, the last before hind limbs) 29-5-28 on male (EBRG 4250), 4-4-9, -01, and 1-27-0 (respectively on three females EBRG 4251–5). Ventrals in 28, 27-27-29 transverse rows with 6–9 scales each (all specimens combined). Tail distinctly compressed without rows of tubercles, with enlarged, keeled scales forming double dorsal crest on distal part of tail. Male with 0 and 1 (total 61) femoral pores; 22 subdigital lamellae on Finger 4, on Toe 4. Three females with 20–2 (mean = 21.7) subdigital lamellae on Finger 4, 2–4 (mean = ) on Toe 4. Size of male (EBRG 4250) 94 mm SVL, 14 mm TL (tail half regenerated), 9.0 mm RHL, 51.0 mm RFL, 28.0 mm HL, 15.5 mm HW, 10.0 mm L4F, 16.8 mm L4T. Size of females 85.0-80.0-7.0 mm SVL, 125 (tail half regenerated)-160- (tail 1/6 regenerated)-145 (tail 1/5 regenerated) mm TL, 1.0-0.0-24.0 mm RHL, 45.0-44.0-44.0 mm RFL, 2.5-21.5-20.6 mm HL, 12.-11.211.0 mm HW, 8.0-7.0-7.8 mm L4F, 1.5-1.5-1.5 mm L4T. Other Neusticurus reported from the Venezuelan Guayana are N. bicarinatus, N. medemi, N. racenisi, and N. rudis. Neusticurus tatei can be easily differentiated from N. racenisi (sympatric in Sarisariñama) by the following characters (those of N. tatei in parentheses): short snout (elongated), irregular scales in frontonasalprefrontal region (regular), smaller scales on flanks and dorsum in a transversal count, up to 6 (larger, up to 9). Neusticurus bicarinatus has six longitudinal rows of tubercles on the dorsum (none). Neusticurus medemi is similar to N. racenisi by having irregular scales on frontonasal-prefrontal region (regular) (Dixon and Lamar 1981). Neusticurus rudis has a moderately short snout (elongate), 4–6 regular or irregular rows of tubercles on the dorsum (none), flanks with prominent trihedral tubercles surrounded by distinctly smaller scales (absent) [from BARRIO-AMOROS & BREWER-CARIAS 2008].|
