Higher Taxa | Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos) |
Subspecies | |
Common Names | E: Arafak Slender-toed Gecko |
Synonym | Gymnodactylus (Heteronota) arfakianus MEYER 1874: 129 Nactus arfakianus — ZUG 2020: 39 |
Distribution | Indonesia (Schouten Islands in the mouth of Cenderawasih Bay) Type locality: “Neu-Guinea”; subsequently, Meyer (1887) identified the locality as Doré, a town on the northeastern coast of Pulau Yapen (=Kepulauan Yapen) |
Reproduction | Nactus pelagicus is a composite of unisexual [parthenogenetic] and bisexual populations. Note however that Zug and Moon (1995) recognized Nactus pelagicus as the asexual species for the populations in southern Vanuatu and elsewhere in Oceania, and N. multicarinatus for the bisexual species from Vanuatu and the southern Solomon Islands. |
Types | Holotype: lost (destroyed during the Dresden firebombing in February 1945. Zug 2020 has not designated a neotype because he has not located any specimens from Doré or Yapen. Other specimens: BPBM 3951, Biak Island; UMMZ 122449, (Numfoor Island) are from the Schouten Islands, of which Yapen is a member. |
Diagnosis | Additional details, e.g. a detailed description or comparisons (879 characters), are available for collaborators and contributors. Please contact us for details. |
Comment | Synonymy: this species has been considered as a synonym of N. pelagicus for most of recent history until it was revalidated by Zug 2020 based on 2 specimens. |
Etymology | “Arfak” derives from the language of the coastal Biak people of the Vogelkop Peninsula and appears to be used for their lowland area (“inferior”) relative to the adjacent Arfak Mountains, the highest mountains on the Vogelkop. Apparently, Meyer used Arfak in a broader geographic sense to label the entire region. |
