Baseprocessa longiprocessa sp. nov.

Fig. 3 A–R.

Description. Measurements. Body length (including tegmina): ♂, 6.5 mm. head width: 1.94 mm; crown length×width: 0.80× 0.70 mm; eye width: 0.65 mm; pronotum length×width: 0.65× 2.10 mm; mesonotum length: 1.25 mm. female, unknown.

Coloration. Ground coloration orange. Crown dull yellow with symmetrical black spots, eyes transparent ( Fig. 3 A ). Face black, with numerous indistinct yellow spots ( Fig. 3 B ). Scutellum black, margin yellow ( Fig. 3 B ). Forewing reddish-brown, with numerous yellow patches, venation black with orange spots; appendix yellowish-green ( Fig. 3 A–D).

Morphology. External features as in generic description.

Male genitalia. Male pygofer abruptly narrowed postero-dorsally in lateral view, apex with a pair distinguish uniform and slender processes on dorsal margin ( Fig. 3 E–F). Connective small ( Fig. 3 G ). Style long, base expanded ( Fig. 3 H ). Subgenital with numerous slender setae from middle to subapex ( Fig. 3 I ). Aedeagal shaft slightly curved, with hook-like process on base in lateral view; apex round, with numerous irregular preapical lateral teeth; subapex with a extremely developed knifelike process ( Fig. 3 J–K).

Material examined. Holotype: ♂, China: Tibet, Motuo Beibeng , 827 m, 17. VII. 2017, collected by Cheng Yangqi.

Diagnosis. The new species is similar to type species B. nigribacka (Fan & Li, 2017) , but can be distinguished by the elongate, slender preapica process on the aedeagus, the yellow margin of the scutellum and the forewing with dark veins distinctly contrasting with the pale membrane.

Etymology. The new species name is derived from the words “ longi ” and “ processa ”, indicating that the aedeagal subapex has a well-developed elongate process.

Distribution. China (Tibet).
