Taxonomy from Mindat.org. Diagnosis from Liu et al. 2010: "Costal area narrow. In forewing, Sc simple, terminating at C near pterostigma; M with 4 branches; Cu 1 and M forked before the cross-vein cu 1 -cu 2." Description from Liu et al. 2010: "Antenna filiform, incompletely preserved. Femur shorter than tibia. Tibial spurs not present. Setae irregularly arranged. Costal area narrow, one cross-vein c-sc between C and Sc. Sc simple, ending at C and extending to pterostigmal area. One short cross-vein sc 2 -r 1 before pterostigma. Rs arised at the same level to cross-vein csc. Rs with 4 branches. Length of R 2 two-thirds that of stem of R 2 + 3. Cross-vein r 1 -r 2 at level of pterostigma. Cross-vein r 3 -r 4 at level of cross-vein r 1 -r 2. Cross-vein r 5 -m 1 + 2 approximately at middle of wing length. Crossvein r 5 -m 1 proximal to cross-vein r 4 -r 5. One cross-vein r 4 -r 5 dividing cell R 4 into 2 cells. Conspicuous thyridium at fork of M, which has 4 branches. M 3 + 4 divided beyond the fork of M 1 + 2; cross-vein m 1 + 2 -m 3 between M 1 + 2 and M 3; cross-vein m-cu not straight, slightly S-shaped. Cu 1 coalesced with M for a short distance and separated from M before cross-vein cu 1 -cu 2. One cross-vein a 1 -a 2 connected 1 A and 2 A. 3 A absent. Female abdomen with 11 segments, segments 9–11 smaller than segment 8. One pair of cerci located at apex of abdomen. Right cercus with 3 segments. Third segment of left cercus not preserved. Basal segments fused with abdomen segment 11. Body length 7.8 mm, forewing length 8.2 mm, width 2.6 mm."
