Mitjaevia shibingensis sp. nov. Figs 1-7 , 15-27

Description.

Vertex pale yellow, with pair of small black apical spots and two irregular markings at sides of coronal suture (Figs 1 , 3 ). Face pale brownish yellow, anteclypeus with apical half dark brown; frontoclypeus with brownish black patches at sides basally (Fig. 4 ). Pronotum mostly dark brown, with pair of symmetrical brownish yellow oval impressed patches medially, showing brownish yellow near anterior margin (Figs 1 , 3 ). Scutellum orange yellow, with brown irregular elliptical spot at base medially (Figs 1 , 3 ). Forewing with orangey and gray patches (Fig. 6 ).

Abdominal apodemes small, not extended to hind margin of 3rd sternite (Fig. 15 ). Male genitalia with subgenital plate relatively short, broadened basally, provided with two long macrosetae at midlength on lateral surface and numerous peg-like setae along dorsal margin basally to near midlength; several microsetae scattered on apical portion (Fig. 17 ). Style elongate, with subapical extension laterally, lateral lobe moderately large (Fig. 18 ). Aedeagal shaft narrow tapered to narrowly rounded apex in lateral view, gonopore arising near midlength on ventral surface; basal apodeme reduced; preatrium well developed (Figs 19 , 20 ). Connective moderately broadly Y-shaped, central lobe well developed (Fig. 21 ). Female 7th sternite as in Fig. 24 . Valvula I elongate, curved dorsad and evenly tapered from base to apex, finely strigate along dorsal margin of apical 1/5 (Fig. 25 ). Valvulae II elongate, slightly expanded blade-like to near apex, thereafter tapered to down-turned apex, with few dorsal roundish teeth distally on right branch (Fig. 26 ). Valvula III tapered distally to narrowly rounded apex (Fig. 27 ).

Measurement.

Body length, males 2.6-2.8 mm, females 2.7-2.8 mm.

Specimen examined.

Holotype ♂: China, Guizhou Prov., Shibing, 27 V 2019, coll. Zhouwei Yuan, Chao Tan and Xiaowei Yuan. Paratypes: 14♂♂, 55♀♀, same data as holotype.

Remarks.

This species has a similar shaped aedeagus to M. korolevskayae but the style has a preapical extension ( “heel”) and a smaller lateral lobe.
