Fanjinga Yu & Yang gen. nov.

Type species.

Fanjinga digitata Yu & Yang, sp. nov., here designated.

Diagnosis.

Within the Alebroides group of Empoascini , the new genus runs to Nulliata Lu, Xu & Qin in the key to genera by Xu et al. (2017), based on the following characters (in order of couplets): MP’ vein arising from r cell, coronal suture not extending onto face, anal tube appendage absent, crown face transition without a dark medial patch and male pygofer not emarginated dorsally, aedeagus with preatrium long. The new genus differs from Nulliata in having the abdominal apodemes long and from Nulliata and other genera in having a finger-like process bearing micro-setae on the lower posterior margin of the male pygofer.

Description.

Relatively robust (Figs 1-3 ). Head slightly narrower than pronotum; vertex short, slightly longer medially than next to eyes, coronal suture reaching to anterior margin of vertex. Ocelli present. Face broad, distinctly broadened at lower part, convex in profile (Figs 3-5 ). Pronotum nearly twice as long as vertex (Fig. 1 ). Forewing with apical cells occupying almost 1/3 of total length, veins RP and MP’ stalked at base, arising from r cell, and MP’’+CuA’ from m cell, r cell longer than m cell, but narrower than m cell, third apical cell triangular (Fig. 12 ). Hindwing with CuA branched, termination of branch distad of coalescence of CuA with MP’’ (Fig. 13 ). Front femur with AM1 enlarged, with one antero-basal macroseta and 8 small setae near tip of femur. Hind femur with macrosetae 2+1+1, hind tibia row AV with 10 macrosetae near apex.

Male basal abdominal sternal apodemes well developed (Fig. 14 ). Male pygofer elongate, dorsolateral fracture distinct, dorsal bridge moderately long, with several rigid microsetae at posterior margin; ventral appendage well developed, extended beyond posterior margin; lower posterior margin with a finger-like process (Figs 6-8 , 15-18 ). Subgenital plate extended slightly beyond pygofer, A-group setae present, B-group setae following A-group setae to tip of dorsal margin, C-group setae arranged in two rows in basal half, then merged into single row to apex; D-group setae thick (Fig. 22 ). Paramere very thin, curved apically, apex with teeth and sensory pits (Fig. 10 , 21 ). Aedeagus slender, preatrium very long, dorsal apodeme absent (Figs 9 , 11 , 19-20 ). Anal tube appendage absent (Fig. 9 ). Connective almost square shaped, apical margin medially concave (Fig. 23 ).

Etymology.

The genus name is an arbitrary combination of letters.

Distribution.

China (Guizhou).
