Revision of the subgenus Phortica (sensu stricto) (Diptera, Drosophilidae) from East Asia, with assessment of species delimitation using DNA barcodes Author Huang, Jia Author Gong, Lu Author Tsaur, Shun-Chern Author Zhu, Lin Author An, Keying Author Chen, Hongwei text Zootaxa 2019 2019-09-30 4678 1 1 75 journal article 25341 10.11646/zootaxa.4678.1.1 96c8a18a-e887-4345-b266-d76076e8416b 1175-5326 3468782 91B46647-B441-41F5-BE27-3A67D699788C Phortica ( Phortica ) orientalis ( Hendel, 1914 ) ( Figs. 6A, 6B , 23 ) Amiota orientalis Hendel, 1914: 116 . Amiota ( Phortica ) antheria Okada, 1977: 20 . Amiota ( Phortica ) orientalis : Okada 1971: 91 (misidentified); Okada 1977: 19 (misidentified). Diagnosis. This species is similar to P . ryukyuensis Chen in Chen & Máca 2012 in the characters of paramere and aedeagus, but can be distinguished from the latter by having two characters of the vertical process of gonopod ( Fig. 23D ): submedian branches (b) of anterior tripartite processes much longer than apical branches (a); base (c) of posterior saccate processes distinctly thinned and stalk-like; in P . ryukyuensis (as fig. 31 in Chen & Máca 2012 ): apical branches (a) of anterior tripartite processes slightly longer than submedian branches (b); base (c) of posterior saccate processes distinctly broadened.
