|Diagnosis||Diagnosis (short): Potamites flavogularis is characterized by the absence of isolated basal flounces of spines and presence of calcareous spinules on flounces of the hemipenis, a short (1,30–1,41 times SVL) and slightly compressed tail without tubercles, tympanum slight- ly recessed, subimbricate ventral scales, lateral body scales lacking conspicuous enlarged tubercles, four longitudinal rows of dorsal tubercles, 6 transverse series of ventral scales, absence of intercalated scales along sides of tail, and absence of tubercles on sides of neck and gular regions. Like their congeners, the new species was found close to vegetation surround- ing streams in primary and secondary forests.|
Diagnosis. a species of Potamites with a single frontonasal; regular longitudinal rows of dorsal tubercules in series of single enlarged and strongly keeled tubercles; absence of enlarged tubercules on sides of body, neck and gular region; tail slightly compressed with no intercalated scales along sides, and a brown spot around nostril. Potamites flavogularis sp. nov. differs from all species of Neusticurus (characteristics in brackets) by presenting a short and slightly compressed tail (long and highly compressed), tympanum slightly recessed (highly), presence of calcareous spinules on flounces of the hemipenis (absent) and sub-imbricate ventral scales (imbricate). From all other species of Potamites except for P. cochranae, it differs by presenting a single frontonasal, lateral body scales lacking conspicuous enlarged tubercles, four longitudinal rows of dorsal tubercles, six transverse series of ventral scales, absence of intercalated scales along sides of tail, and absence of tubercles on sides of neck and gular regions. Like P. cochranae the new species has a conspicuous black or brown spot surrounding nostril but differs from it by presenting a slightly shorter tail (1,34–1,41 times SVL vs 1,53–1,58), by having distinctive and homogeneous dorsolateral and paravertebral longitudinal rows of tubercles formed by a sequential series of unique enlarged and strongly keeled tubercles [irregular and heterogeneous, containing irregularly one or more than one (mostly two) enlarged tubercles more rounded and with keels never so conspicuous], dorsolateral and paravertebral rows of tubercles distinct anteriorly and closely approaching scales from posterior part of head (indistinct anteriorly and not so close from scales on the posterior part of head), a short loreal with its suture with nasal corresponding to less than half to the posterior part of nasal (large loreal, its suture with nasal corresponding to the major part of nasal scale), enlarged scales on posterior part of tight (mostly granular scales), basal flounces of the hemipenial body circulating the assulcate face of the base of the organ (basal flounces of the hemipenial body restricted to the center of asulcate face), and in color pattern where a strong sexual dichromatism is present (absent).
|Comment||Similar species: Potamites flavogularis is closely related, sibling, and sympatric to Potamites cochranae to which it has been previously confused.|
|Etymology||From the Latin flavus (=yellowish) and gularis (=throat).|
