Figs 58A–E , 127 , 149C

Diagnosis: This species can be recognized by the hind trochanter having a pronounced hump ventrobasally covered by crest-like bristles and a few short bristles ventroapically ( Fig. 149C ); surstyli slender in dorsal view ( Fig. 58A ); phallic guide with 5–6 dorso-dorsolateral spines; two long membranous sheaths associated with the ejaculatory ducts; hypandrium with a small projection and a small hairy membranous sheath ( Fig. 58B, D–E ).

Description: MALE: Body length: 2.8 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 times the length of ocellar triangle. Occiput silvery pollinose, less so on upper 1/3. Thorax. Postpronotum pale, with 4–5 pale bristles. Mesonotum (viewed obliquely from front) brownish pollinose, anterior part more grey, grayish also from the side. Scutellum brownish pollinose and with 4–6 weak bristles along the distal edge. Dorsocentral bristles distinct, dark, somewhat longer along frontal edge, numerous long dark bristles around postpronotum. Halter, knob pale, stem brown. Legs. Mid coxa with 2–3 dark bristles. Trochanters and femora dark brown, shining ventrally, silvery pollinose posteriorly except shiny hind femur; knees and basal 1/5 of tibiae yellow (tibiae otherwise dark brown), tarsal segments yellow-brown, ventrally somewhat paler, last segment darker. Hind trochanter with a pronounced little hump and crest-like bristles, distal part with 1–2 short spines ( Fig. 149C ); ventrobasal (one) long bristle on fore and mid femora. Ventroapical row of indistinct spines on fore femur 3–4; 8–10 small, black spines on mid femur; hind femur without ventroapical spines, except 12–14 equally spaced bristles posteroventrally, longer on the distal half, in length up to 0.8 times the width of hind tibia at distal end. Subapical (distal) spines on first four tibiae present (distinct, longer on mid tibia). Hind metatarsus flattened and almost as long as 2–4 combined and with strong, thick bristles ventrally. Pulvilli as long as last tarsal segment. Wing. Length: 3.0 mm. Upper side of basal costal cell with one long dark bristle. Fourth costal section 2.5 times as long as third costal section. Cross-vein r-m at middle of discal cell. 3–4 small brown setulae on tegula. Abdomen. Dissected. tergite 1 and anterior 2/3 of tergite 2 silvery grey. Lateral bristles on first tergite present, 4–5 pale bristles up to 1.5 times as long as hind femur’s width at base. Postabdomen in dorsal view: Dissected. Genitalia. Genital capsule in dorsal view: epandrium longer than wide (MLE:MWE = 1.3). Surstyli symmetrical, broadened at base, slender and elongated, both curved to each other in middle, left surstylus longer than right one ( Fig. 58A ). Genital capsule in ventral view: phallus with three short ejaculatory ducts and two long membranous sheath covered by small hair; gonopods elongated towards surstyli, equal in height, right is slightly wider than left one, subepandrial sclerite long, hypandrium with a small projection towards gonopod and a small hairy membranous sheath ( Fig. 58B ). Genital capsule in lateral view: both surstyli curved towards sternite, more broadened at middle; phallic guide with 5–6 lateral spines (the longest one twice as length as others) ( Fig. 58D–E ). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 58C ).

FEMALE: Unknown.

Etymology: The name lophia is Greek for a mane, crest, comb, tuft or ridge and refers to the crest-like bristles on the hind trochanter.
