Scape and pedicel not enlarged, ﬂagellomeres short, eyes form incomplete bridge, apical palpal segment rounded, M3+4 strongly curved, legs not modiﬁed.
Head: Postocciput ﬂat. Antennae inserted near middle of face. Scape and pedicel not enlarged, widths equal to width of average ﬂagellomere. Flagellum 14-segmented, ﬂagellomeres cylindrical, width about equal to length, setulose. Frons setose. Eyes setulose, emarginate at antennal bases, forming lobes toward middle of head 4–5 facets wide, but dorsal bridge incomplete, separated by distance more than 4x facet diameter. Ocelli three, equal in size to the distance from middle to lateral ocelli, twice the length as from lateral ocellus to eye margin (distance of lateral ocellus from eye margin equal to diameter of ocellus). Face setose. Palpi short, only 2 visible, rounded segments, with numerous hairs. Clypeus bare.
Thorax: Scutum with long lateral, dorsocentral, and acrostichal setae. Scutellum with 6 long setae. Anterior parapsidal suture distinct. Suture between antepronotum and proepisternum oblique. Proepimeron touches mesepisternum at anepisternal suture. Anepisternal cleft narrow, oblique. Mediotergite and laterotergites bare. Metepisternum touches katepisternum.
Wing membrane without macrotrichia, with scattered microtrichia. All veins setose. Costa ends beyond tip of R5, one-third the length between tips of R5 and M1. Sc very short, ends free. R1 short, about 0.5 wing length. R5 about 0.85x wing length, curved slightly, runs very close to R1. M1 conﬁned to apical third of wing. RS base, M1 and stem of M absent. Crossvein r-m fused with R5, horizontal, fused with CuA base. CuA base weak. Base of M3+4 and CuA fork at level of tip of R1. M3+4 curved and well rounded. CuA with two straight segments forming obtuse angle.
Legs: Coxae almost equal in length. Hind coxae bare at base. Fore tibia distally with apical hemispherical anteroapical depression with comb of ﬁne setae. Tarsal claw without teeth.
Abdomen shorter than wings, with 7 visible segments, setose. Sixth and 7th segments twice as short as 5th, 8th retracted. Cerci one-segmented.
Body length = 1.40 mm; wing length = 1.22 mm.
