Alebroides hei Ding, Yu & Yang sp. nov.

(Figs 18–33)

Description. Length. Male 3.7 mm.

Whole body red (Figs 18–21). Eyes grayish-yellow to black (Figs 18–21). Coronal suture deep red (Figs 18, 21). Legs red to light orange-red (Figs 19, 20). Forewing with veins red to reddish-brown (Figs 18, 19, 22).

Head including eyes broader than pronotum in dorsal view, crown short, middle length shorter than width between eyes, coronal suture distinct, not reaching crown (Figs 18, 21). Face slender, convex in lateral view (Figs 19, 20). Head anterior margin roundly produced in dorsal view (Figs 18, 21). Forewing narrow, veins RP and MP’ stalked at base, arising from r cell and MP”+CuA’ arising from m cell, hindwing with CuA branched (Figs 22, 23).

Male dorsal abdominal apodemes relatively long, reaching the end of segment 5 ( Fig. 24 ). Male pygofer with ca.12 rigid macrosetae, and ventral pygofer appendage extended beyond posterior margin, slim and curved ( Figs 25, 26, 27 ). Subgenital plate extended well beyond pygofer side, with 5 A- group setae, ca. 21 B-group spiny setae, 19 C- group setae in two rows, and 3–4 rows D-group setae ( Figs 25, 26, 29 ). Paramere slim, apex denticulate with 2 rows of fine setae ( Fig. 30 ). Connective longer than wide ( Fig. 31 ). Aedeagus with preatrium as long as shaft, shaft curved dorsad and acuminate apically in lateral view, notched in posterior view, with lateral pair of slender curved processes arising near base of shaft, strongly divergent from shaft then curved distad, arched in lateral view ( Figs 31, 32 ). Anal tube process slim, narrow and slightly curved anterad ( Fig. 33 ).

Material examined. Holotype ♂, Motuo , Xizang, China, 95.4642° E, 29.4937° N, 1569.48 m, 3 July 2022, coll. Hong-Li He . Paratypes: 1♂, same data as holotype ; 1♂ same location and time, coll. Yan Ding.

Etymology. The new species name is derived from the family name of collector Hong-Li He.

Remarks. The new species is similar to Alebroides flavoniger Linnavuori, 1960 , mainly in having a pair of lateral processes on the aedeagus, but the new species differs in having the whole body red without a streak (Figs 18–23) (in A. flavoniger body color is yellow with a dark brown longitudinal streak on the midline of the face, along the coronal suture, and the midline of the entire thorax), the anal tube process narrow and slightly curved ( Fig. 33 ) ( A. flavoniger has the anal tube process ( Fig. 36 ) narrow and long, strongly curved in an arch), aedeagus shaft apex with concave teeth and aedeagus processes narrower than the latter and arched dorsad in lateral view ( Figs 31, 32 ). The aedeagus of A. flavoniger is shown in Figs 34, 35 . Dworakowska (1997) described that species as follows: “penis stem in side view narrow, hooked apically, with a “step” on dorsal margin and long lamellate processes of the lamella made by 1st section produced dorsad to near half of length of the stem.”

Distribution. China (Xizang).
