Cyrtodactylus tahuna sp. nov. is a new bent-toed gecko we describe herein based on three specimens from Sangihe, North Sulawesi, Indonesia, an island situated in the northern corner of the Wallacea biodiversity hotspot. The new species is a medium sized Cyrtodactylus with a SVL of up to 78.5 mm in adult males and 79.2 mm in females. It is easily distinguished from all but four species (Cyrtodactylus fumosus, C. halmahericus, C. papuensis, and C. tambora) occurring on Sulawesi as well as in the Moluccas and the Lesser Sunda Islands, by possessing precloacal and femoral pores, enlarged precloacal and femoral scales, and lacking transversely enlarged median subcaudal scales. It differs from C. fumosus by the presence of tubercles on the ventrolateral fold, more unkeeled dorsal tubercles (19 versus 4-7) and a pit-like precloacal depression in males (versus groove in males); from C. halmahericus by presence of smaller scales between the enlarged precloacal and femoral scales (versus a continuous series of enlarged precloacofemoral scales) and a continuous series of precloacofemoral pores, as well as the presence of a pit-like precloacal depression in male (versus groove in males), from C. papuensis by possessing a pit-like precloacal depression in males (versus a groove ); and from C. tambora by the presence of tubercles on the dorsal surface of the brachium and the possession of femoral pores. Our contribution, along with several other recent descriptions of bent-toad geckos from Southeast Asia, clearly indicating that the diversity of the genus Cyrtodactylus in Indonesia is still underestimated.
塔胡纳弯趾虎新种（Cyrtodactylus tahuna sp. nov.）是一种新的弯趾虎，我们在此基于来自印度尼西亚北苏拉威西省桑义赫岛的三个标本对其进行描述。桑义赫岛位于华莱士生物多样性热点地区的东北角。新物种是一种中等大小的弯趾虎，成年雄性的头体长可达78.5毫米，雌性为79.2毫米。它很容易与苏拉威西岛以及摩鹿加群岛和小巽他群岛上除四种（烟熏弯趾虎、哈马黑拉弯趾虎、巴布亚弯趾虎和坦博拉弯趾虎）之外的所有其他物种区分开来，其特征是具有泄殖腔前孔和股孔、扩大的泄殖腔前鳞片和股部鳞片，且没有横向扩大的尾下正中鳞片。它与烟熏弯趾虎的区别在于腹侧褶上有瘤、背侧瘤更无棱（19个对4 - 7个）以及雄性有一个坑状泄殖腔前凹陷（而雄性烟熏弯趾虎为沟状）；与哈马黑拉弯趾虎的区别在于扩大的泄殖腔前鳞片和股部鳞片之间有较小的鳞片（而不是连续的一系列扩大的泄殖腔前股部鳞片）以及连续的一系列泄殖腔前股部孔，还有雄性有一个坑状泄殖腔前凹陷（而雄性哈马黑拉弯趾虎为沟状）；与巴布亚弯趾虎的区别在于雄性有一个坑状泄殖腔前凹陷（而不是沟状）；与坦博拉弯趾虎的区别在于肱部背面有瘤以及有股孔。我们的研究成果，连同最近对东南亚弯趾虎的其他一些描述，清楚地表明印度尼西亚弯趾虎属物种的多样性仍被低估。
