Luo, Guimei, Wang, Jinqiu & Song, Yuehua, 2022, Three new species of the leafhopper genus Mitjaevia Dworakowska from Karst areas in Southwest China (Hemiptera, Cicadellidae, Typhlocybinae), ZooKeys 1125, pp. 159-169 : 159

Mitjaevia solitaria sp. nov.

Figs 6-10 , 24-31

Material examined.

Holotype: ♂, China: Guizhou Province, Bijie , 6.VI.2021, coll. Jia Jiang and Ni Zhang. Paratypes: 18 ♂♂, 3 ♀♀, same data as holotype .

Diagnosis.

The new species can be distinguished from other species by the aedeagal shaft with only one thick finger-like process at base. Pygofer dorsal appendage not extended beyond hind margin of pygofer. Style strong; preapical lobe obvious. Subgenital plate wide and short with one hook-like process on apex.

Description.

Vertex yellowish (Fig. 6 ). Pronotum mostly grayish black (Figs 6 , 8 ). Scutellum yellowish, transverse impression distinct (Fig. 6 ). Face brownish yellow; anteclypeus brownish except lighter base (Fig. 9 ). Forewing brownish, with large milky white or whitish patches.

Abdominal apodemes small, located in 3rd sternite (Fig. 31 ).

Male genitalia. Pygofer dorsal appendage weakly expanded at base, not extended beyond hind margin of pygofer (Fig. 29 ). Pygofer lobe broad, with fine setae scattered outer lateral surface (Fig. 28 ). Subgenital plate wide and short, with three macrosetae on lateral surface, and one hook-like process on apex (Fig. 27 ). Style strong; preapical lobe obvious (Fig. 24 ). Aedeagal shaft as long as or little shorter than that of preatrium, with one finger-like process basally; dorsal apodeme small (Figs 25 , 26 ). Connective Y-shaped; arms and central lobe slender (Fig. 30 ).

Body length (including wings). ♂, 3.1-3.2 mm, ♀, 3.0-3.2 mm.

Remarks.

The new species is similar to M. aurantiaca (Mitjaev, 1969), but can be distinguished by the aedeagal shaft with only one thick finger-like process at base; the style is stronger and the subgenital plate is shorter and wider.

Etymology.

The new species is named from the Latin word solitarius, referring to the aedeagal shaft with only one processes at the base.
