Diagnosis

Kokeshia hsiaoi can be recognized from all other species of Kokeshia by tergite VIII subdivided into two hemitergites, left hemitergite VIII with an elongate, slender, curved process with an appendage split into 3‒5 branches ( Figs 13D–E, G , 14 A−B).

Redescription

Male

MEASUREMENTS (in mm) (male non-type specimens, N = 3). Total body length 1.18–1.29; length of head 0.24–0.26, maximum width across eyes 0.38–0.41, interocular distance 0.26–0.28; length of antennal segment I 0.07–0.08, segment II 0.07–0.08, segment III 0.30, segment IV 0.34; length of labial segment I 0.08–0.09, segment II 0.05–0.06, segment III 0.06–0.07, segment IV 0.09–0.10; middle length of pronotum 0.37–0.40, length of collar 0.06–0.07, humeral width 0.65–0.68; length of forewing 1.09– 1.17; length of fore femur 0.29–0.33, fore tibia 0.33–0.35, fore tarsus 0.12–0.13; length of middle femur 0.32–0.36, middle tibia 0.33–0.35, middle tarsus 0.13; length of hind femur 0.38–0.41, hind tibia 0.53– 0.60, hind tarsus 0.17–0.18; greatest width of abdomen 0.54–0.56.

MACROPTEROUS. Small sized (about 1.18–1.29 mm).

COLORATION. Body yellowish brown to light brown, appendages yellowish brown ( Fig. 13A–C ). Surface, vestiture and general structures as in generic description, except mentioned below.

HEAD. Interocular distance 0.66–0.70 × length of maximum width across eyes.

THORAX. Humeral width 1.69‒1.76 × as long as middle length of pronotum. Venation of forewing in accordance with general pattern of genus. C+Sc, R+M, R and basal portion of 1An darker than wing surface, other veins slightly darker than wing surface ( Fig. 26G ).

ABDOMEN. Tergite VII slightly asymmetrical, right portion wider than left portion, sternite VII nearly symmetrical. tergite VIII subdivided into two hemitergites, left hemitergite VIII with elongate, slender, curved process with appendage split into 3‒5 branches, its inner margin with large, prominent process ( Figs 13D–E, G , 14A ).

GENITALIA. Pygophore simple, asymmetrical, dorsal surface with dense microtrichia. Posterior margin of right dorsum with a triangular process ( Fig. 13 D−F), which function might be to fix position of phallus. posterior area with about twelve relatively long setae. Parameres strongly asymmetrical, left paramere ( Figs 13E , 14C‒D ) with broadly rounded laminate extension directed dorsal near base, and with flattened and tapering distal projection, and curved inward; right paramere ( Figs 13E , 14F‒G ) with flattened, round and relatively slender distal projection. Apical portion of phallus ( Figs 13D‒E , 14H ) tubular, slender, forming more than one coil outside of pygophore.

Female

Unknown.

Distribution

China: Guangdong, Zhejiang ( Fig.20 ).
