本研究提供了三个翅目物种的修正：Choristopanorpa drinnani Jell & Duncan，白垩纪chorista parva Jell & Duncan， Prochoristella leongatha Jell & Duncan和一个以前被认为是双翅目的化石标本（No. 1）。NMVP103336)，由Jell和Duncan（1986）从Koonwarra（澳大利亚）描述。利用紫外光下的荧光可以对翅膀脉纹进行详细的研究，并导致对一些标本的分类位置的重新考虑。新的图纸，照片和一些描述。基于M1+2独特的早期分叉，P. leongatha被转移到新建立的Australochorista gen. 11 .属和Australochoristidae fam新科。11 .龙心蜂翅脉分布模式。11 .与Prochoristella Riek相似，但也显示出非Permochoristidae的典型特征，并可能与某些全景总纲（sensu Novokshonov, 2002），特别是正亲和总纲和全景总纲。australochistidae的系统发育关系尚不清楚，但观察到的分类学特征不支持它是包括澳大利亚特有的Choristidae在内的任何鞘翅目现存类群的祖先。这个新发现的科可能出现在澳大利亚，并在没有任何现存的代表的情况下灭绝了。(C) 2014 Elsevier Ltd.版权所有。
The study provides revision of three species of Mecoptera: Choristopanorpa drinnani Jell & Duncan, Cretacochorista parva Jell & Duncan, Prochoristella leongatha Jell & Duncan and one fossil specimen considered previously as Diptera (No. NMVP103336), described by Jell and Duncan (1986) from Koonwarra (Australia). Using fluorescence under UV light allowed the detailed studies of wings venations and led to reconsideration of taxonomical position of some specimens. New drawings, photographs and some description were made. Based on the unique early forking of M1+2, the species P. leongatha was transferred to the newly established genus Australochorista gen. nov. and the new family Australochoristidae fam. nov. The wing venation pattern of A. leongatha comb. nov. resembles that of Prochoristella Riek, but also shows characters not typical of Permochoristidae and possibly synapomorphic with some Panorpoidea (sensu Novokshonov, 2002), particularly of orthophlebiid and panorpoid grades. The phylogenetic relationships of Australochoristidae are not quite clear, but observed taxonomical characters do not support it as an ancestral group to any living group of Mecoptera including the Australian endemic Choristidae. This newly described family probably emerged in Australia and extinct without any recently living representatives. (C) 2014 Elsevier Ltd. All rights reserved.
