Hoser, R. T. 2022. Eleven new species of Australian gecko within the genus Heteronotia Wermuth, 1965. LSIDURN:LSID:ZOOBANK.ORG:PUB:1C7EAA91-A50D-4AEE-B6BE-3E6D17E9F9E7 Australasian Journal of Herpetology 55:3-48. Published 15 May 2022. ABSTRACT The Australian gecko genus Heteronotia Wermuth, 1965 has been subject of recent taxonomic studies including Wells and Wellington (1985), Fujita et al (2010) and Pepper et al. (2013), two of which resulted in the formal naming of taxa. The most commonly accepted taxonomy of just five recognized species is seen in Cogger (2014), including two forms named by Pepper et al. (2013). Notwithstanding the identification of further self-evidently unnamed forms by Pepper et al. (2013), all of which were common knowledge among herpetologists in Australia prior, it is significant that no one has sought to assign names to other sometimes common and widespread species in the genus. To rectify this error, obviously unnamed species and subspecies within the genus are formally named according to the rules of the International Code of Zoological Nomenclature (Ride et al. 1999 as amended online since) for the first time. These new taxa are identified on the basis of morphological divergence, known biogeographical barriers affecting similarly constrained reptiles and the genetic evidence previously published. These include one species and a subspecies in the H. spelea (Kluge, 1963) complex (currently with three recognized species), Heteronotia planiceps Storr, 1989 is split five ways, with four new species named, as well as a new subspecies and the Bynoe’s Gecko H. binoei (Gray, 1845) is split into nine species, with two available subjective synonyms resurrected and six new species formally named for the first time. A further two morphologically divergent insular subspecies in that complex are also formally named. In summary the genus is expanded from 5 widely recognized species to include 2 resurrected forms and 11 newly named species, to make it have a total of 18 species, with four recognized subspecies. There may yet be other species or subspecies in the genus awaiting formal description.
