Empoascanara (Empoascanara) lancanga Pu & Song , sp. nov.

( Figs 1g –j , Figs 2a–g )

Description. Body yellowish-brown ( Fig. 1g ). Vertex rounded, slightly protruding forward, with one irregular black spot on anterior margin ( Figs 1g, i ). Eyes black ( Fig. 1g ). Pronotum yellowish-brown, wider laterally, mid-length about twice as long as length of vertex ( Fig. 1i ). Scutellum yellowish-brown, with distinct transverse impression ( Figs 1j, i ).

Abdominal apodemes small, not extended beyond hind margin of 3rd sternite ( Fig. 3g ).

Male genitalia. Pygofer lobe broad, with scattered microsetae at lower basal margin; pygofer dorsal appendage strongly expanded at base ( Fig. 3e ). Subgenital plate shorter, wider sub-basally, slightly upturned apically, densely peg-like setae and microsetae along upper margin, 3 long macrosetae on outer surface ( Fig. 3d ). Style long and slender, with two terminal points at apex; preapical lobe distinct ( Fig. 3a ). Connective nearly Y-shaped, with central lobe small and stem well developed ( Fig. 3f ). Aedeagal shaft slightly curved dorsad, with scattered micro-setae and sculptures on dorsal area; preatrium almost as long as shaft, with one single strong and long process arising from base, and bifurcated at apex; gonopore subapical, on ventral surface. ( Figs 3b, c ).

Measurement. Male length 2.6-2.7 mm, female length 2.4-2.5 mm (including wing).

Material examined. Holotype: ♂, CHINA, Yunnan Prov., Lancang , 2021.Ⅴ.20, coll. Guimei Luo.

Remarks. This species is similar to Empoascanara linnavuorii ( Dworakowska,1972) , but has the vertex with one irregular black spot on the anterior margin ( Figs 1j, i ); the subgenital plate with densely peg-like setae and microsetae along the upper margin ( Fig. 3d ); and the aedeagal shaft with scattered microsetae and sculptures on the dorsum ( Figs 3b, c ).

Etymology. The new species is named after its type locality: “Lancang” County, Yunnan Province, China.
