Higher TaxaSphaerodactylidae, Gekkota, Sauria, Squamata (lizards: geckos)
Common NamesE: Union Island Clawed Gecko 
SynonymGonatodes daudini POWELL & HENDERSON 2005 
DistributionCaribbean: Union Island, St. Vincent, and the Grenadines

Type locality: Water Rock Reserve on the northern slope of Mt. Taboi above Chatham Bay (elevation ∼120 m), Union Island (12°35’N, 61°25’W), St. Vincent and the Grenadines.  
TypesHolotype: KU 275717, University of Kansas Natural History Museum (original number: Milwaukee Public Museum Field Herpetology, MPM-FH 2307; male; collected by Mark de Silva and Matthew Harvey. 
DiagnosisDiagnosis: A very small Gonatodes with a pointed snout, a bright red-orange iris, and 39-44 scales around midbody (>70 in all congenerics). Scales along mid-ventral line between anterior margin of the forelimbs and vent 34-38. Proximal subdigital lamellae as wide as digits, in total 18-22 under fourth toe. Two lateral rows of scales on distal portions of fingers and toes. Tail ventrally with two enlarged single midventral scales, each in contact with one latero-distal scale per side, followed by a divided mid-ventral in contact with two latero-distal scales per side. Males with three conspicuous pairs of dorsolateral white spots surrounded concentrically first by black and then by red. No other species of Gonatodes has comparably large body scales, small SVL, bright red-orange iris, or a body pattern consisting of three prominent dorsolateral pairs of ocelli [from POWELL & HENDERSON 2005]. 
CommentHabitat: remnant dry forest; the species appears to be terrestrial while most species of Gonatodes are arboricolous, with larger froms frequently found closer to the base of trees.

Behavior: mainly diurnal

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyNamed after Jacques Daudin (b. 1925), a naturalist, author, and conservationist who has lived on the island of Union, the Grenadines, for some 30 years and has over 30 adopted children.
