Mitjaevia salaxia sp. nov.

Figs 11-15 , 32-39

Material examined.

Holotype: ♂, China: Guizhou Province, Bijie , 5.VI.2021, coll. Jia Jiang and Ni Zhang. Paratypes: 1 ♂♂, 6 ♀♀, same data as holotype .

Diagnosis.

The new species can be identified by the two pairs of abdominal apodemes and the aedeagal shaft with lamellate-like processed at base. Style apex long and slender. Subgenital plate long, expanded near caudal.

Description.

Vertex pale yellow (Fig. 11 ). Pronotum yellowish, with symmetrical brownish black impressed patches medially (Figs 11 , 13 ). Scutellum (Fig. 11 ) yellow, with basal triangles black and area under transverse impression black too. Face brownish gray; anteclypeus with central area brownish (Fig. 14 ). Forewing brownish, with large milky white or whitish patches.

Second abdominal apodemes and third abdominal apodemes small and short, lamellate, not exceeded 3rd sternite (Fig. 39 ).

Male genitalia. Pygofer dorsal appendage simple, curved upward in lateral view, hook-like apically (Fig. 37 ). Pygofer lobe broad, with many long fine setae on lateral surface, with a small process at caudal edge ventrally (Fig. 36 ). Subgenital plate long, with three macrosetae near apex (Fig. 35 ). Style apex long and slender; preapical lobe large (Fig. 32 ). Aedeagal shaft slender, with pair of long processes arising from base (Figs 33 , 34 ). Connective Y-shaped; stem slender; arms and central lobe well developed (Fig. 38 ).

Body length (including wings). ♂, 3.0-3.1 mm, ♀, 2.9-3.0 mm.

Remarks.

The new species is similar to M. protuberanta Song, Li & Xiong, 2011, but differs in having the “lamellate” processed arising from base of aedeagal shaft and not branched at apex; with two pairs of abdominal apodemes.

Etymology.

The new species is named after its type locality Salaxi town.
