Type material. Holotype: ♂ (Mime-0104- HNU): China, Guangxi Zhuang Autonomous Region: Chongzuo City , Longzhou County, Nonggang National Nature Reserve , Sanlian Site , Longdan , 22°32.10'N, 106°50.22'E, 310m, 30.X.2017, Ailan He, Keke Liu, Qu Cai, Jihe Liu, Jinxin Liu and Zongguang Huang leg.

Etymology. The specific name is derived from the Latin adjective clavatus , meaning “clavate” (i.e., thicker at the apex than at the base) and refers to the shape of the cymbium apex in prolateral view.

Diagnosis. The males of Mimetus clavatus n. sp. differ from those of all other Mimetus species by the ovalshaped subtegular apophysis and the triangular flag-shaped cymbial apex ( Figs 9D, F, G View FIGURE 9 , 10B–D View FIGURE 10 ). Females remain unknown.

Description. Male (Holotype). Habitus as in Fig. 9A View FIGURE 9 . Total length 1.85. Carapace 0.78 long, 0.79 wide. Opisthosoma 0.99 long, 1.15 wide. Sternum 0.54 long and 0.45 wide. Labium wider than long. Clypeus height 0.15. Eye sizes and interdistances: AME 0.09, ALE 0.08, PME 0.07, PLE 0.07, AME–AME 0.04, ALE–AME 0.03, PME–PME 0.04, PME–PLE 0.06. MOA 0.09 long, anterior width 0.03, posterior width 0.04. Leg measurements see Table 3.

Cephalothorax: Carapace ( Fig. 9A–C View FIGURE 9 ) yellowish, long oval and glabrous, widest at coxae II and III; with a large deep brown pattern between ocular area and fovea, slightly constricted at one third near the fovea; a pair of dark patches on the lateral margins of the carapace near the coxae I and II; fovea inconspicuous. Sternum yellowish. Labium reddish brown. Chelicerae ( Fig. 10E, F View FIGURE 10 ) reddish brown, with six promarginal peg teeth and two retromarginal teeth. Endites brown, longer than wide. Leg color similar to carapace, with irregular brown stripes.

Abdomen ( Fig. 9A, B View FIGURE 9 ): yellow-brown, sub-tetrahedral, wider than long and widest in medial region, covered with sparse setae, with whitish spots and many deep-brown patches dorsally.

Pedipalp ( Figs 9D–G View FIGURE 9 , 10A–D View FIGURE 10 ): tibia long and thin, twice as long as cymbium, slightly swollen distally, with a few long macrosetae. Cymbium with many especially long setae dorsally, strongly extended apically to form a triangular flag-shaped outgrowth ( Fig. 9D View FIGURE 9 ). Paracymbium broad, anchor-shaped. Subtegular apophysis oval-shaped, with rugged surface. Sclerotized area of conductor complex, whorled and rolled up forming several apophyses, including one protecting the apical end of embolus. Top of conductor membranous area with pilose cuticular projections. Embolus tubular, strongly curved around the membranous area of conductor and forming ca. 3/4 circle, proximally swollen.

Female. Unknown.

Distribution. China (Guangxi) ( Fig. 23 View FIGURE 23 )
