Common NamesE: Admiralty or Bumble-bee Slender-toed Gecko 
SynonymNactus kunan FISHER & ZUG 2012
Nactus kunan — ZUG 2020: 48 
DistributionPapua New Guinea (Admiralty Islands: Manus Island)

Type locality: Papua New Guinea, Admiralty Islands, Manus Island, Sohoniliu Village (2.11296°S 147.14912°E)  
TypesHolotype: USNM 576300, adult female, collected by Robert N. Fisher and villagers from Sohoniliu Village, 26 May 2010. Paratype. Same collection data as holotype PNGNM 25190 (RNF8981), juvenile female. 
DiagnosisDiagnosis. Nactus kunan sp. nov. is a member of the Nactus pelagicus species group and differs from all other members except N. galgajuga by a pattern of broad alternating dark (black or dark brown) and light bands on neck, trunk, and tail. It differs from N. galgajuga by the golden yellow of its light bands instead of the white bands of N. galgajuga. N. kunan sp. nov. also possesses a unique head pattern among Nactus taxa with a sharply contrasting yellow crown and eyelids on a black background.

Definition. A bisexual taxon of geckos (Gekkoninae) with moderate adults (♀ 56 mm SVL) with smooth subcaudals, no postmental scales, moderate number of dorsal tubercle rows (16–17) and high number of tubercles (45–47) in parasagittal row (TubRow), enlarged tubercles on dorsal surface of hindlimb, and no precloacal pores in females (unknown for males).
Note that Zug and Fisher (2012) labeled the subcaudals as keeled but that these are tiny regenerate scales and not typical subcaudal enlarged scales. Genetic relationship to N. galgajuga would suggest unregenerated subcaudals are smooth (Zug 2020).

Coloration in life is similar to only one other Nactus, N. gal- gajuga, in the possession of bold coloration. Dorsally, adult is yellow and dark brown and yellow in 6 irregularly edged trans- verse bands from the neck to the base of the tail (Zug 2020). 
CommentDistribution: see map in Zug 2020: 47 (Fig. 18). 
EtymologyThe specific name comes from the Tokples people’s (Nali language) term for bumblebee; this is in reference to the striking bicolor yellow and black banding of holotype. Note that the description explicitly says Nactus kunan FISHER & ZUG although the author order is inversed on the paper.
