Diagnosis

Kokeshia drepanoides sp. nov. can be recognized from all other species of Kokeshia by tergite VIII subdivided into two hemitergites, left hemitergite VIII with a flattened, curved, sickle-shaped process. ( Figs 9D, E, G View Fig , 10 View Fig A−B).

Etymology

The species epithet is derived from the Greek adjective ʻ drepanoides ʼ, means ʻsickle-shapedʼ, and refers to the curved, sickle-shaped process of tergite VIII.

MACROPTEROUS. Small sized (about 1.2‒1.31 mm).

COLORATION. Body light brown to brown, appendages yellowish brown ( Fig. 9A–C View Fig ). Surface, vestiture and general structures as in generic description, except mentioned below.

HEAD. Interocular distance 0.67–0.69 × length of maximum width across eyes.

THORAX. Humeral width 1.69‒1.77 × 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. 26E View Fig ).

ABDOMEN. Tergite VII and sternite VII slightly asymmetrical. Tergite VIII subdivided into two hemitergites, left hemitergite VIII with a flattened, curved, sickle-shaped process, and horizontally directed mesad; prominent setae near its inner margin ( Figs 9D–E, G View Fig , 10 View Fig A−B). Right hemitergite VIII simple, posterolateral portion elongated subtrapezoidal, projecting posteriad, prominent setae near posterior margin ( Figs 9E‒F View Fig , 10C View Fig ).

GENITALIA. Pygophore asymmetrical, dorsal surface with rows of microtrichia on transverse projections, posterior margin with curved setae. Parameres strongly asymmetrical, left paramere ( Figs 9E View Fig , 10D‒E View Fig ) with broadly rounded laminate extension directed dorsal near base, and with flattened and elongate distal projection, and curved inward from middle of it; right paramere ( Figs 9E View Fig , 10F‒G View Fig ) with flattened, blunt and relatively slender distal projection. Apical portion of phallus ( Figs 9D‒E View Fig , 10E View Fig ) tubular, short, forming half coil outside of pygophore, with triangular laminate at middle portion.
