Goniogryllus chongqingensis Chen & Zheng, 1995

Goniogryllus chongqingensis Chen & Zheng 1995: 213, 216; Chen and Zheng 1996: 291; He 2018: 518; Zhao and Liu 2022: 244.

Goniogryllus octospinatus syn. nov. Chen & Zheng 1995: 215; Han et al. 2015: 21; He 2018: 518; Zhao and Liu 2022: 244.

Material examined.

G. chongqingensis : CHINA • 2 ♀ (3440, 3441); Chongqing City , Beibei District, Jinyunshan (106 ° 23 ′ E 29 ° 50 ′ N); 19 Aug. 2020; Hui-Cong Xie leg. ( ECNU) . — G. chongqingensis (= G. octospinatus ): CHINA • 1 ♂ 1 ♀ (4551, 4554); Hubei Prov., Lichuan City, Wangying Town, Fubaoshan (108 ° 44 ′ E 30 ° 11 ′ N); 19 May. 2021; Wen-Xuan Bi leg. ( ECNU) .

Diagnosis.

Apterous; all glabrous (Fig. 3 F, G ); yellow stripes on the head without bifurcation (Fig. 4 D, E ); maxillary palpus black with yellow stripes on the apex of the 4 th joint and the dorsal side of the 5 th joint (Fig. 5 D, E ); male genitalia: apical part of epiphallus with two divided lobes, the inside of lobes prominent (Fig. 6 G ). G. chongqingensis is similar to G. emeicus by Chen & Zheng, 1995. The difference is that G. chongqingensis is larger than G. emeicus in body size, and there is a finger-like process on the base fusion of endoparameron of G. chongqingensis ( Chen and Zheng 1995 b) .

Remarks.

The main difference between G. chongqingensis and G. octospinatus is: the pronotum and the hind femur of G. chongqingensis are black, while there are yellow stripes on both sides of pronotum and a yellow longitudinal stripe on the superior border of the hind femur of G. octospinatus ( Chen and Zheng 1995 b) . However, the molecular result indicates that they are the same species. They all possess the above morphological features in diagnosis. See details for discussion about the color and pattern of the pronotum and hind femur as intraspecific variations (Fig. 7 , 8 ). Therefore, we place G. octospinatus syn. nov. in a junior synonym of G. chongqingensis .

Measurements.

(mm) ♂: BL 12.13; PL 2.57; HFL 7.04. — ♀: BL 12.24–13.82; PL 3.24–3.66; HFL 8.27–8.56; OL 9.40–10.99.

Distribution.

China (Chongqing, Hubei, Sichuan).
