|Distribution||Japan (Kyushu, NE Ryukyu Islands: Yakushima, Tanegashima)|
Type locality: Anbo, Yakushima, Ryukyu Archipelago.
|Types||Holotype: JSC *** #522, adult female (cited in original description like this, with asterisks etc., Japan Snake Center, Yabuduka-cho Ota, Gunma Prefecture, Japan)|
|Diagnosis||Although G. yakuensis strongly resembles G. hokouensis, it can be discriminated from the latter by possessing a distinctly enlarged internasal as compared to the immediately posterior scales (as large as or slightly larger than in G. hokouensis) and paired apical tubercles, each located anterior to the caudal annular groove, throughout the original tail (absent, or present but usually less than four and rarely eight in the basal region of the original tail in G. hokouensis) [Shibata et al. 1981].|
However, Okada (1998), by examining morphological characters of 31 Gekko specimens from southern Kyushu, stated that the conditions of both the internasal and the paired caudal tubercles varied more or less continuously among them, and that seven of the specimens remained unidentified due to the possession of combinations of character states inconsistent with Shibata’s (1981) diagnoses.
|Comment||Hybridization: Gekko hokouensis occasionally hybridizes with Gekko yakuensis (Toda et al. 2001, Okamoto et al.: Genbank sequences).|
