Goniogryllus yunnanus ( Wu & Zheng, 1992)

Callogryllus yunnanus comb. nov. Wu & Zheng 1992: 95; Yin and Liu 1995: 45; He 2018: 518; Zhao and Liu 2022: 244.

Material examined.

CHINA • 1 ♂ 2 ♀ (4224, 4226, 4228); Yunnan Prov., Yuxi City, Xinping County, Ailaoshan (101 ° 26 ′ E 23 ° 58 ′ N); 16 Jul. 2021; Zhu-Qing He leg. ( ECNU) .

Diagnosis.

No wings in females, wings short to the third segment of abdomen in males; all glabrous (Fig. 3 K ); yellow stripes on head without bifurcation (Fig. 4 H ); maxillary palpus black with yellow stripes on the dorsal side of the 5 th joint (Fig. 5 G ); male genitalia: apical part of epiphallus with two divided lobes, the inside of lobes strongly concave (Fig. 6 B ).

Remarks.

The molecular result shows that C. yunnanus and Goniogryllus are in the same clade. C. yunnanus and Goniogryllus possess some of the same morphological features such as yellow stripes on each side of the head ( Wu and Zheng 1992). Besides, the male genitalia of C. yunnanus and Goniogryllus are similar, they differ only in the degree of emargination on the inside of epiphallus. Combining molecular result and structures of genitalia, we consider C. yunnanus has close relationship with Goniogryllus rather than Callogryllus kilimandjaricus Sjöstedt, 1910 , the type species, from Africa. Thus, Callogryllus yunnanus Wu & Zheng, 1992 is transferred to the genus Goniogryllus , as Goniogryllus yunnanus comb. nov.
