Type locality: south end of Cerro Corocoro, 1220 m elevation (5°42’N, 66°10’W), Amazonas, Venezuela.  
Reproductionoviparous 
TypesHolotype: EBRG 3130 (field no. CWM 19795), an adult male; collected March 1, 1995, AMNH–TERRAMAR Expedition. See locality 2 on map (fig. 1 in MYERS & DONNELLY 2001). PARATOPOTYPES: AMNH 147040–147045, EBRG 3128–3129, 3131–3132, from same locality as holotype, collected February 28– March 1, 1995, AMNH–TERRAMAR Expedition. PARATYPES: AMNH 147046, EBRG 3133– 3134, from above Yutajé, Río Corocoro, 180 m (5°37’N, 66°07’W); collected March 2, 1995, AMNH–TERRAMAR Expedition. See locality 3 on map (fig. 1 in MYERS & DONNELLY 2001). 
DiagnosisDIAGNOSIS: A large Tropidurus having several tufts of elongate, spinous scales on the neck; complete gular and antegular folds; anteriorly imbricate head scales; small, slightly imbricate, acutely pointed, thornlike body scales; and a middorsal crest from rear of head onto the tail. Tropidurus panstictus most nearly resembles T. lumarius, from which panstictus differs in larger size and a different color pattern, which is much lighter and which includes profuse pale speckling in adults (see later, under Comparison with Tropidurus lumarius). Tropidurus panstictus differs from other spiny-necked tropidurines in the same way that T. lumarius does (Donnelly and Myers, 1991: 31–32). MYERS & DONNELLY 2001: 75 provide a key to Venezuelan tropidurines. 
CommentAbundance: only known from its original description (Meiri et al. 2017). This is one of the species called 'lost' and 'rediscovered' by Lindken et al. 2024.

Diet: a large percentage of the diet of this species (10-30%) consists of ants (Lucas et al. 2023). 
EtymologyThe species name panstictus is an adjective derived from the Greek “pan-” (all, all over) and stiktos (dappled, spotted, punctured), in allusion to the profuse speckling and spotting over the head, body, and limbs of adults.
