Thorax: Predominantly brown, parts silver and brown pruinose; antepronotum, postpronotum, and median postpronotal lobes silver pruinose; lateral postpronotal lobes apruinose, light yellow to light brown; scutum brown, sometimes antero-laterally lighter brown, predominantly apruinose, lateral and posterior margins brown pruinose; presutural dc setae: 1 short, 1 intermediate, 1 long, postsutural dc setae: 3–5 short anteriorly oriented setae, 5–6 short acr setae, 1 npl and 1 spa seta; anepisternum brown, few yellow anepisternal setae on anterior and dorsal margins, anteriorly and dorsally silver and remaining parts brown pruinose; anepimeron, proepimeron, katepisternum, katepimeron and meron+metanepisternum brown, proepimeron silver pruinose, katepisternum anteriorly and antero-dorsally silver pruinose, posterodorsally brown pruinose, central area apruinose, meron+metanepisternum brown pruinose anteriorly, medially apruinose, posteriorly silver pruinose, metkatepisternum brown, silver pruinose; scutellum brown, silver pruinose, few very short apical scutellar setae.

Legs: light yellow to light brown; coxae and trochanters light yellow; pro and mes femora light yellow with 2 transverse light brown bands, met femur mostly light yellow to light brown, clubbed in distal 1/3, club brown, yellow transverse band at proximal margin of club, scattered brown macrosetae on pro and mes femora, met femur with distinct rows of brown macrosetae; pro and mes tibiae light yellow with 2 light brown transverse bands, met tibia brown with median yellow transverse band, about 2 times as long as width of tibia, all tibiae with yellow to light brown erect macrosetae in rows, pro and mes tibiae with 2 long apical macrosetae, met tibia with 2 apical macrosetae; tarsus light yellow to light brown, proximal tarsomere always longer than 2 following tarsomeres combined, short and long macrosetae on all tarsomeres; all empodia minute, sometimes met empodium 1/4 of median claw; median claw more than half as long as lateral claw.

Wings: length = 4.4–4.7 mm; few microtrichia, trichoid spicules short, symmetrical dorsally and ventrally, about 18–20 on M1 between r-m and diversion of M1 and M2; cell d small, terminating in M2 and M3, r-m situated proximal to separation of M3 and CuA1; R1 reaching C well proximal to R5 and M1 joining C, R2+3 straight proximally and smoothly arching posteriad distally; halter light yellow, knob dark brown, length = 0.9 mm.

Abdomen: Brown; T2 length = 2.7–3.0 mm, T2 with yellow transverse band medially, T2–3 with short, erect, evenly spaced macrosetae, remaining T with irregularly spaced and longer macrosetae, T7–8 with lateral sensory areas.

Male terminalia: epandrial halves fused medially, distal tip straight, pointed; epandrium and hypandrium fused proximally, gonocoxite and hypandrium fused to form gonocoxite-hypandrial complex; Aedeagus: not protruding from hypopygium, very short, prong a wide tube; Female genitalia- spermathecae occupying only segment 8, individual spermathecal ducts long and coiled; spermathecal reservoirs not sclerotized, as wide as individual ducts, forming a coil.
