It resolves issues of taxonomy and nomenclature, including by means of publication (this paper), effectively settling any disputes about potential validity of names for use according to the ICZN rules for various well-defined taxa. In accordance with the ICZN code, this paper formally names one new genus (Jackypython gen. nov.), one new subgenus (Rawlingspython subgen. nov), two new species, (Morelia wellsi sp. nov. and Australiasis funki sp. nov.) and one new subspecies, (Chondropython viridis adelynhoserae subsp. nov.). A neotype is desig- nated for A. amethistina. Furthermore, four subspecies within the genus Aspidites and one subspecies within Leiopython are formally named. Assessed are matters relating to the genus Leiopython and a 2008 paper by Wulf Schleip. This paper redefines the family composition at tribe level. As a result, one new tribe is erected, namely Broghammerini tribe nov.. For the pre-existing tribe Moreliini there are four newly identified subtribes, namely Moreliina subtribe nov., Aspiditesina subtribe nov., Katrinina subtribe nov. and Antaresiina subtribe nov..

INTRODUCTION Due to a number of factors including the commercial significance The “true” pythons of Africa, Asia and Australasia had for most of of these snakes, their generally large size and popularity among the last century been placed in the sub-family Pythoninae, although hobbyist keepers and more recently government-backed attempts in recent years, there has been a move by taxonomists to elevate to remove these snakes from private keepers in several countries, this status to full family (as in Pythonidae), which is agreed by this there have been numerous studies into the taxonomy of these author. snakes.
