Diagnosis | Diagnosis: “A moderately sized member of the T. loriae Group (SVL up to 600 mm) with the following unique combination of characters: two scales covering vent; three infralabials contacting first genial; a single intergenial between posterior genials, widest posteriorly; preocular contacting nasal (87%) or not (13%), not contacting internasal (93.3%); relatively long snout (SNL/SNW mean = 1.16, range = 0.99–1.40); relatively large eye (EY/SNL mean = 0.22, range = 0.17–0.24); two postoculars (93%); usually three (67%) posterior temporals; ventral scale count sexually dimorphic with overlap (t12 = 3.7381, p = 0.001416), 172–184 ventrals in eight males, 178–197 in six females; subcaudals sexually dimorphic without overlap, 43–57 in males, 20–29 in females; SCR strongly sexually dimorphic, with the relative contribution of subcaudal scale number in males twice what it is in females (20.0–24.0 in males, 10.0–13.1 in females); pale parietal blotch usually absent (present in four small specimens); pale markings on prefrontals present; and venter uniformly yellow.” (Kraus et al. 2022) Additional details (9388 characters) are available for collaborators and contributors.

Etymology | Named after the Greek σπίλος (spilos = spot) and ῥῠ́γχος (rhynchos = snout), in recognition of the distinctive prefrontal blotch that typifies the species. |
