Material examined. Table 1.

Pristimantis gaigei is a small to medium-sized frog characterized by having a distinct tympanum; annulus partially concealed dorsally and posteriorly by supratympanic fold; skin of dorsal surfaces shagreened; skin of venter smooth or feebly granular along lateral and posterior borders of ventral disk; discoidal folds and prominent arm slender ( Lynch 1980). This species is eas- ily distinguished from related species (i.e., P. penelopus ) also distributed in the Magdalena river valley by having smooth and dark gray ventral surface, a bright yellow band on the forearm, and no calcar tubercle (in contrast with brown ventral surface with cream flecking, absence of yellow band and presence of calcar tubercle in P. penelopus ).

Pristimantis jaguensis Rivera-Prieto, Rivera-Correa & Daza 2014: 225 .

Material examined. Table 1.

A moderated-sized frog characterized by a wide variation in color; absence of nuptial pads, discoidal fold and conical calcar tubercles; flanks and belly white to cream without blotches as well as iris yellow ocher to copper with thick brown reticulation and cream sclera (Rivera et al. 2014). This species co-occurs in the Magdalena river valley with Pristimantis penelopus and P. viejas and may be distinguished from both by having smooth skin and lacking a calcar tubercle (dorsum with tubercles including the heel in P. penelopus and P. viejas ) and the concealed surfaces of the thighs yellow without blotches (orange spots on the concealed surfaces of the limbs in P. viejas ; yellow spots on the concealed surfaces of the limbs, sometimes forming a reticle, in P. penelopus ).

Eleutherodactylus penelopus Lynch and Rueda-Almonacid 1999: 310 .

Pristimantis penelopus — Hedges et al. 2008: 128.

Material examined. Table 1.

A moderated-sized frog with a shagreen dorsum; tubercles posteriorly and on flanks; no dorsolateral folds; skin of venter brown with cream flecking; discoidal folds prominent; subanal tubercles only slightly larger than granules on underside of thighs; and iris copper with black reticulation. Males have spots on concealed surfaces of the thighs, a feature shared with Pristimantis viejas ; nevertheless, these spots are usually yellow (sometimes forming a reticle) in P. penelopus and orange in P. viejas . Pristimantis penelopus is also similar to P. latidiscus from which it may distinguished in having a brown venter with cream flecking (in contrast to a cream venter with brown reticulation) (Lynch and Rueda-Almo- nacid 1999, Restrepo et al. 2017).

Eleutherodactylus viejas Lynch and Rueda-Almonacid 1999: 311 .

Pristimantis viejas — Hedges et al. 2008: 121.

Material examined. Table 1.

A small-sized frog with numerous non-conical tubercles on dorsum; absence of dorsolateral folds; finger I shorter than finger II; toe V very long; brown above with darker brown markings; venter cream stippled with brown and posterior surfaces of the thighs brown with large cream spots. Superficially similar to Pristimantis taeniatus in lacking a canthal stripe, but readily distin- guished from that species in having orange spots on the concealed surfaces of the limbs (absent in P. taeniatus ; Lynch and Rueda-Almonacid 1999).

Colostethus inguinalis ( Cope, 1868) : Figure 4B Prostherapis inguinalis Cope 1868: 10 .

Colostethus inguinalis — Savage 1968: 745.

Material examined. Table 1.

A moderate-sized dendrobatid with a pale oblique lateral stripe extending from groin only to around midbody; pale ventrolateral stripes present; pale dorsolateral stripes absent and toes moderately webbed. Colostethus inguinalis may be distinguished from C. aff. fraterdanieli (also distributed in the Magdalena river valley) by having an incomplete pale oblique lateral stripe (complete in C. aff. fraterdanieli ) and by the throat coloration of adults (black in adult males, white unpigmented or faintly pigmented gray or brown in adult females in C. inguinalis ; spotted in adult males and immaculate in adult females in C. aff. fraterdanieli ). It differs from C. pratti both in toe webbing (absent in C. pratti ) and adult male throat coloration (pale gray or brown with irregular white spots, forming a faint, mottled or reticulated pattern in C. pratti ).
