Diagnosis: This species can be recognized by the two patches of spines on the hind trochanter ( Fig. 146E View FIGURE 146 ); long and condensed bristles on membranous area; surstyli elongated in dorsal view ( Fig. 78A View FIGURE 78 ); phallic guide with some different-sized spines ( Fig. 78B View FIGURE 78 ); one of ejaculatory ducts with some saw-like teeth ( Fig. 78B View FIGURE 78 ); both gonopods with a finger-like projection in ventral view ( Fig. 78B View FIGURE 78 ).
Description: MALE: Body length: 3.0– 3.1 mm. Head. Flagellum acuminate; yellow-brown. Face silvery pollinose. Frons, upper part shining black, lower part distinctly silver pollinose; eyes touching for distance equal to 1.5–1.8 times the length of ocellar triangle. Occiput silvery pollinose, less so on upper half. Thorax. Postpronotum pale, with 4–5 distinct pale bristles. Mesonotum (viewed obliquely from front) brownish pollinose, anterior part silver pollinose, slightly grayish also from the side. Scutellum silver pollinose and with 5–7 weak bristles along the distal edge. Dorsocentral bristles well developed, dark, longer on frontal part and numerous dark bristles around postpronotum. Halter, knob pale, stem black. Legs. Mid coxa with 2–3 spines. Trochanters and femora black, shining ventrally, silvery pollinose posteriorly except shiny hind femur; knees yellow, tibiae black, tarsal segments dark brown, only yellowish ventrally; fore metatarsus is transparent in ventral view. Hind trochanter with a few short dark spines (5–8) ventrobasally and (2–3) shorter ones ventroapically ( Fig. 146E View FIGURE 146 ). Ventroapical row of spines on fore femur missing, 4–6 very short, black spines on mid femur; no spines on hind femur, only 6–8 pale bristles posteriorly on distal half (as long as the width of hind tibia at the distal end); ventrobasal spines (2) present on fore and weaker on mid femur; hind tibia slightly bent at middle in posterior view. Subapical (distal) spines on first four tibiae present, very short. Hind metatarsus extremely flattened, spoon-like (extending posterior edge, widest at basal 1/3) ( Fig. 151E View FIGURE 151 ), second tarsomere slightly longer than 3–5. Pulvilli as long as last tarsal segment. Wing. Length: 3.0 mm. Upper side of basal costal cell with one dark and long bristles. Fourth costal section 1.5–2 times as long as third costal section, fourth section appears to be unusually short. Cross-vein r-m slightly distal to middle of discal cell. 4–5 dark setulae on tegula. Abdomen. Viewed obliquely from front tergites subshining black, tergite 1 silvery grey, sides silvery pollinose on tergites 4 and 5 (the latter with larger spots). Dispersed long dark bristles on tergites present, the longest on ST8 and up to 3.5–4 times as long as width of hind tibia at base. Lateral bristles on first tergite present, 6–8 brown bristles in a patch up to as long as 1–1.2 times the width of hind femur at distal tip in lateral view. Postabdomen in dorsal view: T6, S7 invisible; T5 1–1.5 times as long as syntergosternite 8 (ST8). Genitalia without dissection: ST8 large, black, hairy with longest bristles on posterior part; membranous area round, posteriorly directed, the longest bristles originate from membranous area; tip of epandrium brown; surstyli pale, appear elongated and uniformly broad. Genitalia. Genital capsule in dorsal view: epandrium wider than long (MLE: MWE = 0.8). Surstyli asymmetrical, elongated, left longer than right one ( Fig. 78A View FIGURE 78 ). Genital capsule in ventral view: subepandrial sclerite covered with some transverse streaks in middle; both gonopods with a finger-like projection extended towards surstyli, left rather longer than right one ( Fig. 78B View FIGURE 78 ), phallic guide with 5–6 different-sized spines dorsolaterally (longer ones extended towards left surstylus); phallus with three ejaculatory ducts, one bears 10–11 saw-like teeth along its side. Genital capsule in lateral view: left surstylus straight in basal two thirds, bent towards sternite in apical one third; right surstylus curved towards sternite ( Fig. 78D–E View FIGURE 78 ); ejaculatory apodeme flat, sperm pump elongated, linear ( Fig. 78C View FIGURE 78 ).
FEMALE: Unknown.
Etymology: The name planca is derived from the Latin plancus, flat-footed, in reference to the flattened hind metatarsus.
