Diagnosis
Kokeshia acutiformis sp. nov. can be recognized from all other species of Kokeshia by male tergite VIII not subdivided into two hemitergites, only a long, flattened, acuminate process at right portion of tergite VIII, the process bent at about ⅓ from its apex (Figs 1D‒G, 2A‒B).
Etymology
The species epithet is derived from the Latin prefix ʻacut -ʼ and suffix ʻ- formis ʼ, means ‘acuminate shaped’, refers to the acuminate process of tergite VIII.

MACROPTEROUS. Small sized (about 1.28‒1.32 mm).
COLORATION. Body yellowish brown to light brown, appendages yellowish brown (Fig. 1A‒C). Surface, vestiture and general structures as in generic description, except mentioned below.
HEAD. Interocular distance 0.55–0.59 × length of maximum width across eyes.
THORAX. Humeral width 1.66‒1.68 × 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. 26A).
ABDOMEN. Tergite VII slightly asymmetrical, right portion wider than left portion, sternite VII nearly symmetrical. Tergite VIII not subdivided into two hemitergites, only a long, flattened, acuminate process at right portion of tergite VIII, process bent at about ⅓ from its apex (Figs 1D‒G, 2A‒B).
GENITALIA. Pygophore slightly asymmetrical, dorsum with rows of tooth like microtrichia, posterior area with about twelve relatively long setae (Fig. 1D‒G). Parameres strongly asymmetrical, left paramere (Figs 1E, 2D‒E) with broadly squarish laminate extension directed dorsal near base, and with flattened and elongate distal projection; right paramere (Figs 1E, 2F‒G) with flattened and acute, near triangular distal projection, curved inward at middle portion. Apical portion of phallus (Figs 1D‒E, 2C) tubular, short, forming one incomplete coil outside of pygophore.
Female
