Figs 23A–E, 116
Diagnosis: This species can be recognized by the distinct ventroapical spine on the hind trochanter; elongated surstyli, left one longer and club-shaped in dorsal view (Fig. 23A); both gonopods with a thumb-like projection towards surstyli; phallic guide with 3–4 different-sized dorso- dorsolateral spines, one is longer and sinuous; subepandrial sclerite with condensed transverse wrinkles in ventral view (Fig. 23B); phallus bearing some teeth apically before ejaculatory ducts in lateral view (Fig. 23D–E).
Description: MALE: Body length: 2.6 mm. Head. Scape, pedicel, flagellum light brown. Flagellum tapering. Face silvery pollinose. Frons, upper part shining black; lower part distinctly silver pollinose; eyes touching for distance equal to 2 times the length of ocellar triangle. Occiput silvery pollinose with scattered short dark bristles. Thorax. Postpronotum pale, with 2–3 short pale bristles. Mesonotum (viewed obliquely from front) silvery pollinose, anterior part close to postpronotum, greyer. Scutellum silvery pollinose and with 6–8 very short bristles along distal edge. Dorsocentral bristles short, dark, longer in frontal half, numerous pale bristles around postpronotum present. Halter, knob and stem pale, tip brownish. Legs. Mid coxa with 3–6 different-sized dark bristles. Trochanters brown, femora darker, shining ventrally, silvery pollinose posteriorly except shiny hind femur; knees and basal 1/6 of tibiae yellow (tibiae otherwise brown), tarsal segments light brown. Hind trochanter grey pollinose with a distinct ventroapical spine; ventrobasal spines present (1) on fore and mid femur. Hind femur without ventroapical spines. Subapical (distal) spines on first four tibiae present (short). Hind tarsomeres not flattened, hind metatarsus almost as long as 2–4 combined, dorsally all tarsomeres with erect dark bristles. Pulvilli shorter than last tarsal segment. Wing. (damaged). Upper side of basal costal cell with 2–3 short to medium dark brown bristles. Abdomen. Viewed obliquely from front tergites brown-black, tergite 1 silvery grey. Lateral bristles on first tergite present, 4–6 dark bristles up to as long as ¾ of hind femur’s width at base. Genitalia. Genital capsule in dorsal view: epandrium rather quadratic-shaped (MLE:MWE = 1.02). Surstyli elongated, left longer and wider than right one, both surstyli widened at the basal fourth, narrowed in the middle, broadened at the apex, left one club-shaped, both curved to each other at apex (Fig. 23A). Genital capsule in ventral view: both gonopods widened at base with a thumb-like projection towards surstyli; phallic guide with 3–4 different-sized dorso- dorsolateral spines, one is longer and sinuous; subepandrial sclerite widened in the middle with condensed transverse wrinkles (Fig. 23B); Genital capsule in lateral view: both surstyli straight in basal two thirds, left one bent towards sternite apically, right one slightly curved towards sternite apically. Phallus trifid with some teeth apically before ejaculatory ducts (Fig. 23D– E). Ejaculatory apodeme tube-like, bent, with a bulb in its middle (Fig. 23C).
FEMALE: Unknown.
Etymology: The name is from the Latin clava, club or cudgel and refers to the club-shaped left surstylus.
