Discussion. When examining the Homogryllacris specimens collected from Yunnan, we discovered four specimens sampled from Jinping, Yunnan are very similar to Homogryllacris yunnana Shi, Guo & Bian, 2012 with regard to the posterior processes on male tenth abdominal tergite, but they differ from the latter in the following: posterior processes of male tenth abdominal tergite distinctly shorter, basal halves cylindrical, apical halves compressed, sickle-shaped, not decussate, apical areas slightly incurved, tips subacute. Furthermore, DNA sequencing was implemented in two of these four specimens sampled from Jinping, Yunnan and two specimens of Homogryllacris yunnana Shi, Guo & Bian, 2012 sampled from Meizihu, Pu’er, Yunnan based on COI gene, respectively, the genetic distance between them is about 4.1%, which is far below the minimum value of interspecific genetic distances (The interspecific genetic distances range are 6.59–19.49% in the genus according to our analysis). As a consequence, with the consideration of morphological and molecular evidence, we regard these four specimens sampled from Jinping, Yunnan as a geographical population of Homogryllacris yunnana Shi, Guo & Bian, 2012 and the morphological difference mentioned above belongs to intraspecific variation.
