TypesHolotype: MZUSP 49153 (field number FMEDEM 1465), adult male, collected by W. W. Lamar and F. Medem, 22 October 1977. 
DiagnosisDiagnosis: A moderately large Gonatodes, with maximum SLV of 47.6 mm. Scales around midbody 96–123. Ventral scales in a longitudinal row 44–55. Proximal subdigital lamellae as wide as digits, in total 14–21 under fourth finger, 17–25 under fourth toe. Two or three lateral rows of scales on distal portion of fingers and toes. Tail with midventral scales distinctly wider than long, forming a repetitive sequence of two single midventrals (one after the other), each in contact with one laterodistal scale per side, followed by a divided (only on proximal portion of tail, when present) or single midventral in contact with two laterodistal scales per side (respectively 1’1’2” and 1’1’1”). A white suprahumeral bar bordered by black, present both in males and females, although more conspicuous in males; it reaches dorsally at least up to the dorsolateral region, in some females it almost reaches the middorsal region; never in the form of an ocellus. Males with head dorsally without vermiculation; back and limbs finely vermiculated; gular region without dark streaks.
CommentBehavior: diurnal 
EtymologyThe species is named after Dr. Carlos Rivero-Blanco, who made an extensive study on Gonatodes, as well as contributions to environmental conservation in Venezuela.
