Processina hunanensis Yu & Zhang sp. nov.

( Figs. 1 , 2 )

Description. Body length (including tegmina), male: 5.0 mm.

Body pale yellow to brown. Crown ( Fig. 1 , A, C) deep yellow, with large black spot medially; apex of lateral frontal suture black, two light symmetrical spots on anterior margin in dorsal view. Face ( Fig. 1 , D) dark yellowish except with darker tinge in frontoclypeus and anteclypeus. Pronotum ( Fig. 1 , A, C) brown with posteror margin black and anterolateral margins yellow. Exposed part of mesonotum ( Fig. 1 , A, C) concolorous with pronotum but with basal dark brown angles and two medial pale yellow lines, scutellum ( Fig. 1 , A, C) lighter than the former with apex yellowish white. Forewing ( Fig. 1 , A, B) hazel, veins of clavus yellowish; base with faint reddish markings. Legs ( Fig. 1 , A, B, C, D) yellow, tarsal apices black. Venter of thorax and abdomen ( Fig. 1 , B, D) yellow, distal part of male subgenital plates ( Fig. 1 , B) dark brown.

Body small and slender. Crown ( Fig. 1 , A, C) broadly rounded in dorsal view; coronal suture obscure; ocelli anterior to line between anterior eye angles, the distance between ocelli approximately 1/3 interocular width. Face smooth ( Fig. 1 , D); anteclypeus swollen, broad basally and narrow apically; transclypeal suture obvious, junction flat, slightly apically expanded beyond gena. Antennae ( Fig. 1 , B, C, D) slightly shorter than median length of crown; antennal pits near upper corner of eyes in anterior view and not overlapping frontoclypeus. Pronotum ( Fig. 1 , A, C) almost trapezoidal, posterior margin concave. Forewing ( Fig. 1 , A, B) apices exceeding posterior margin of pygofer by about 1 mm.

Male pygofer ( Fig. 2 , A) slightly produced dorsally, lobe with posterior margin angularly convex, with few small setae and a macroseta on posteroventral margin. Pygofer process ( Fig. 2 , A, B) relatively short, strongly curved posterodorsally in lateral view, extending posteriorly to middle part of lobe, expanded preapically, unbranched. Anal tube ( Fig. 2 , A) extended to apex of pygofer. Subgenital plate ( Fig. 2 , C) ventral surface some long thin setae dispersed on inner side and few microsetae distributed in middle. Style ( Fig. 2 , D, E) somewhat broad, narrowed anteapically, with several long microsetae and a few short setae at apex. Connective ( Fig. 2 , D) with anterior arms divergent, shorter than stem. Aedeagus ( Fig. 2 , F, G, H) exceeding posterior margin of pygoer lobe; basal apodeme irregularly expanded dorsally in lateral view; shaft long, slender and parallel-sided, tubular, evenly curved dorsally, apex bent anterad and tapered to point, with retrorse thorn-shaped median ventral process at mid-length; gonopore on posterior margin at base of distal extension; ventral margin of aedeagus with clavate anterior process.

Material examined. Holotype: ♂ ( NWAFU), Hunan Province, Shaoyang, Huangsang National Nature Reserve , 26°21'32'' N 110°8'6'' E, 1040 m, 28.V.2021, Coll. Ai Deqiang. Etymology. The specific epithet refers to the type specimen locality. Remarks. This new species is similar externally to P. dashahensis but differs in having the male pygofer process unbranched; and the aedeagus with a single preapical spine and an unpaired distal process.
