Paramritodus concavicaudus Zhang sp. nov.

( Figs 6 , 12 , 47–57 )

Diagnosis. Male. Body yellowish brown ( Fig. 6 ). Upper part of face, genae and lora ( Fig. 12 ) pale brown, frontoclypeus and anteclypeus yellowish brown. Pronotum ( Fig. 6 ) with triangular mark, small, black on anterior margin, mesonotum with basal triangles mark black. Forewings ( Fig. 6 ) brown, veins dark brown.

Male genitalia. Pygofer ( Figs 48–49 ) with ventral margin strongly concave dorsally; inner process S-shaped, not reaching caudal margin; anal tube surpassing pygofer lobe ventral margin and hook-like terminally. Subgenital plates distinctly shorter than pygofer.Aadeagus ( Figs 50–51 ) with developed dorsal apodeme and elongate preatrium; aedeagal shaft slightly curved dorsally and tapered to apex, with elongate process on each side above preatrium, gonopore subapical on ventral surface. Connective ( Figs 52–53 ) as in generic diagnosis. Style ( Fig. 54 ) curved dorsally at nearly 45° angle, apophysis of uniform width to apex fork-like, ventral margin with a small number of setae, dorsal margin with 14–16 teeth.

Female. Similar in overall coloration to male, but face slightly darker. Crown yellowish brown, with pale brown maculae on either side of median line closer to eyes.

Female genitalia. Seventh sternite ( Fig. 56 ) concave in dorsal view. Second valvulae ( Fig. 57 ) regularly broadened in lateral view, bearing approximately 9 teeth along dorsal margin.

Measurements. Male: 4.3–4.4mm, Female: 4.2–4.5mm.

Material examined. Type. Holotype: 1 ♂, CHINA, Guangxi Prov., Chongzuo City, Longzhou, 26.vii.2021, coll. Wei Wang ( IMNU). Paratypes: Guangxi Prov., 2 ♂, 4 ♀, data same as holotype; 1 ♂, 1 ♀, Guangxi Prov., Mt. Damingshan , 20.vii.2022, coll. Qiuyi Zhu ( IMNU) .

Distribution. China: Guangxi.
