Mitjaevia dworakowskae sp. nov. Figs 8-14 , 28-41

Description.

Vertex light yellow, with two pairs of irregular black preapical spots distributed symmetrically (Figs 8 , 10 ). Face milky yellow, anteclypeus with central area brownish; frontoclypeus with brownish black patches at sides basally (Fig. 11 ). Pronotum mostly black, with pair of symmetrical pale-yellow oval impressed patches medially, also showing pale yellow near anterior margin (Figs 8 , 10 ). Scutellum milky yellow, with longitudinal black stripe between scutellar suture and apex (Figs 8 , 10 ). Forewing with brown and brownish yellow patches (Fig. 13 ).

Abdominal apodemes small, not extended beyond hind margin of 3rd sternite (Fig. 28 ). Male genitalia with subgenital plate laterally with 3 macrosetae at midlength and three more distal shorter macrosetae, dorsal peg-like setae restricted to central part (Fig. 30 ). Style elongate with preapical extension on inner surface, lateral lobe large (Figs 31 , 32 ). Aedeagal shaft narrow slightly sinuate and tapered to acute apex in lateral view with gonopore arising near midlength of ventral surface; basal apodeme reduced (Figs 33 , 34 ). Connective broadly Y-shaped, central lobe slender (Fig. 35 ). Female 7th as in Fig. 38 . Valvulae as in previous species (Figs 39-41 ).

Measurement.

Body length, males 2.3-2.4 mm, females 2.4-2.5 mm.

Specimen examined.

Holotype ♂: China, Guizhou Prov., Shibing, 27.V.2019, coll. Zhouwei Yuan, Chao Tan and Xiaowei Yuan. Paratypes: 14♂♂, 19♀♀, same data as holotype.

Remarks.

This species can be distinguished by the narrow and slightly sinuate aedeagal shaft in lateral view and the style with a subapical extension on the inner surface with a greatly enlarged lateral lobe.
