|Distribution||Ecuador (Canelos), Colombia, N Venezuela, NW Brazil (?), N Peru|
Type locality: Canelos, Ecuador
|Types||Syntypes: BMNH 19220.127.116.11-12 (3)|
|Diagnosis||Diagnosis. A relatively large Gonatodes, with maximum SLV of 52.6 mm. Scales around midbody 109–131. Ventral scales in a longitudinal row 49–61. Proximal subdigital lamellae as wide as digits, in total 17–22 under fourth finger, 21–27 under fourth toe. Three or four 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”). |
Coloration: A white suprahumeral bar, bordered by black, present both in males and females, although more conspicuous in males; it reaches dorsally between the dorsolateral and middorsal regions. Males with head dorsally without vermiculations; back and limbs with a vermiculated pattern of dark and light spots; no dark streaks on gular region (at least in preservative).
|Comment||Taxonomy: populations previously assigned to Gonatodes concinnatus have been described as Gonatodes riveroi.|
Distribution: because some populations of Gonatodes concinnatus have recently been described as other species the distribution of this species may be much smaller.
Description: G. concinnatus shows dramatic sexual dimorphism (see Fig. 6 in STURARO & AVILA-PIRES 2011).
Behavior: mainly diurnal
Synonymy: Rivero-Blanco (1968), based on specimens from the type locality but without examining the type material of G. ligiae, considered it a synonym of G. concinnatus. Gonatodes concinnatus ligiae DONOSO-BARROS 1967 has been elevated to full species status by STURARO & AVILA-PIRES 2011.
