Body length 16.0 mm from anterior margin of head to posterior margin of abdominal segments; cerci length 8.0 mm (Fig. 1). Head (Fig. 2 A, B) reddish-yellow, epicranial suture distinct; compound eyes small and dark, each with a small pit on inner side. Antennae 17 - segmented, basal segment long; segment 2 as wide as its length; segment 3 three times longer than segment 2, covered with a few setae; length of segment 4 nearly two-thirds that of segment 3; segments after the third gradually prolonged and covered with dense setae; segments 10 and 15 pale (Fig. 1). Pronotum dark with metallic luster, anterior margin straight with a median expansion, posterior and lateral margins forming a wide arc, covering the scutellum; two rounded humps present lateral to the median suture. Elytra well-developed, dark with distinct metallic luster, length about twice the width, lateral margins arc-shaped, posterior margins truncate (Fig. 2 A). Scales of hindwings short and trapezoidal, posterior margins truncate, color similar to elytra but posteromedial corners pale (Fig. 2 A).

Abdomen brown; tergum 3 with two small glandular folds, tergum 4 with two glandular folds; last dorsal segment with parallel lateral margins, posterior margin sub-trapezoidal and slightly concave medially, with two large lateral lobes and two smaller median lobes. Subgenital plate broad and oval, posterior margin with a shallow median concavity. Pygidium short but wide, lateral margins concave, posterolateral corners projected into two obtuse lobes. Forceps (Fig. 3) long and incurved, basally broad and apically sharp; inner margin of basal sixth and apical sixth glabrous, remainder with small teeth. Genitalia (Figs 4, 5) long, slightly constricted at apical third; paramere long, hook-shaped, apically constricted into a long spine; penis lobe movable; basal vesicle sclerotized with two parts, one larger and denticulate, the other smaller. Female (Figs. 6 – 8). Body length 16.0 mm; cerci length 5.0 mm. Generally similar to male (Figs. 6, 7); apex of antennal segment 10 and segments 11, 12 and 17 pale (Fig. 6).

1965866AD53E6169FF60F1F5BE984E55.taxon	etymology	Etymology. The species is named for the type locality, Chongqin City.	en	Ye, Xiao-Han, Gu, Jun, Zhang, Mei, Chen, Zhi-Teng (2020): Description of Chelisoches chongqingensis sp. nov. (Dermaptera: Chelisochidae) and redescription of Platylabia major Dohrn, 1867 from China. Zootaxa 4790 (3): 551-563, DOI: 10.11646/zootaxa.4790.3.9
1965866AD53E6169FF60F1F5BE984E55.taxon	discussion	Remarks. The new species is assigned to genus Chelisoches based on the lateral groove on the hind tibia, shorter antennal segments 4 and 5 than segment 3, and the similarity of the penis with the type species C. morio (Srivastava 2003, Chen & Ma 2004). The type locality, Chongqin City, is distant from the localities of other Chelisoches spp. Chelisoches chongqingensis sp. nov. is characterized by the following characters: forceps of the male slender and without large teeth, forceps of the female strong and with small inner teeth (Dubrony 1879, Burr 1917, Günther 1934, Chen & Ma 2004). The pygidium of the male is similar to other species in the Oriental region, but the pygidium shape of the female is distinctly diagnostic and can easily separate C. chonqingensis n. sp. from other species.	en	Ye, Xiao-Han, Gu, Jun, Zhang, Mei, Chen, Zhi-Teng (2020): Description of Chelisoches chongqingensis sp. nov.

Redescription of female (Figs. 13 – 14). Generally similar to male (Fig. 13). Last dorsal segment (Fig. 14) gradually narrowed to posterior margin, posterolaterally with two pyramid-shaped projections. Pygidium near-rectangular, posteromedial margin slightly concave.

1965866AD5386167FF60F18DBA984BEC.taxon	discussion	Remarks. In China, P. major was previously known only from Guangxi, Yunnan and Hainan provinces in southern China (Chen & Ma 2004, Hopkins et al. 2020). We obtained new specimens of this species from Guangdong and Fujian provinces thus, extending its distribution eastwards and slightly northwards (Fig. 15). This species is expected to be found in other provinces of southern China, such as Hunan and Jiangxi provinces.	en	Ye, Xiao-Han, Gu, Jun, Zhang, Mei, Chen, Zhi-Teng (2020): Description of Chelisoches chongqingensis sp. nov.
