Type locality: Popayán, W Colombia [there are both a city and a province of that name in Colombia, see KOCH et al. 2011 for a discussion].  
Reproductionoviparous 
TypesHolotype: ZFMK 21341 
DiagnosisDiagnosis (Tab. 3). (1) A Polychrus with a maximum known SVL of 170 mm; (2) dorsal and gular crest absent; (3) 63 to 82 scales around midbody; (4) 75 to 105 scales in middorsal row from behind the occipital scales to the level of the posterior edge of the thigh; (5) femoral pores 9 to 21 on one side (Fig. 6E); (6) lamellae on finger IV 25–36; (7) lamellae on toe IV 35–45 (Fig. 6D); (8) tail 2.36–3.55 times longer than SVL; (9) dorsal scales smooth or with 1–3 keels; (10) ventral scales with 1–5 keels; (11) gular scales oval, mostly striated, much larger than ventrals, those on gular fan widely separated by granular skin (Fig. 6C); (12) a sexual dichromatism present [from KOCH et al. 2011]. 
CommentSynonymy: partly after Peters et al. 1970. KOCH et al. 2011 synonymized P. spurrelli with P. gutturosus. 
EtymologyThe name gutturosus is Latin meaning ‘‘with enlarged throat,’’ and alludes to the extensible, saclike dewlap of males of this species.
