Female
(
Figs 2G, H
). Length
9.5 mm
. Head black, reddish yellow on wide ventromedial part of face (
Fig. 2L
); postocellar area widely dark brown (
Fig. 3P
); labrum red yellow or brown; antenna black, basally narrowly yellow (
Fig. 3X
); mandible reddish brown, basally dark brown, with yellow spot on outer basal part; palpi yellow. Thorax red yellow, dark brown to black on most of lateral mesoscutal lobe, most of posterolateral sunken part of mesoscutum, mesoscutellar appendage, anteromedial part of mesopostnotum, metascutum, wide part of anepimeron, anterior margin of katepimeron, and ventral part of metepisternum (
Figs 2G, H
, 4M, N). Legs red yellow (
Fig. 2H
); fore and middle coxae basally narrowly blackish; hind coxa widely black; middle and hind tibiae basally pale yellow; hind trochanter widely dark brown. Wings colorless transparent (
Fig. 2G
); veins brown to black; most of vein C and bases of vein 1A and 2A+3A yellow; vein R1 basal to stigma widely pale; stigma brown, black on narrow margins and basal third.Abdomen red yellow; second to eighth terga dorsally widely black along posterior margins, and their laterotergites narrowly black along posterior margins; posterior sterna narrowly darkened along posterior margins; ninth tergum posteroventrally black; ovipositor sheath with valvifer 2 widely black, valvula 3 mostly black; cercus dark brown to black.
Postocellar area distinctly swollen; lateral furrow distinct (
Fig. 3P
). OOL:POL:OOCL 1.0:1.0:0.9–1.0. OOCL 2.8–3.1× lateral ocellus length. Inner margins of eyes convergent below (
Fig. 2L
). Distance between eyes at level of torulus 2.0 × major axis of eye. Supraclypeal area moderately swollen. Clypeus with ventral margin very slightly concave medially; median height 1.0 × torulus height. Malar space 1.0–1.1 × median ocellus width. Antenna with 22–23 antennomeres (
Fig. 3X
); first flagellomere without serration, with apical breadth in lateral view 0.9–1.0 × dorsal length; serrations of third to seventh flagellomeres largest.

Distance between cenchri 0.7–0.8 × major axis of cenchrus (Fig. 4M). Metascutellum in dorsal view posterolaterally angulated, with posterior margin truncate; median length 0.4–0.5 × major axis of cenchrus. Hind leg with posterior tibial spur with length 1.0–1.1 × dorsal length of first tarsomere, 0.9–1.1 × apical breadth of tibia in lateral view; dorsal length of second and third tarsomeres combined 1.5–1.6 × dorsal length of first.
Valvula
3 in
dorsal view about 3.0 × as wide as cercus, apically with round lateral projection and small acute medial projection (
Fig. 5K
); scopa about 1.5–2.0 × as wide as cercus, in posterior view long oval, about 2.5 × as high as wide (
Fig. 5L
). Lance with posterior projection on processus articularis apically not extending to most basal annular suture of lance (
Figs 5T, U
). Lancet
Fig. 6I, J
; lamnium with 9 annuli and length from ventral end of first ctenidium to apex 2.2 × maximum width; ctenidia nearly straight except second arched and third slightly arched; sclerite before first annulus narrow; serrula of second annulus with or without precalcar (absence of precalcar probably due to severe wear,
Fig. 6J
) and serrula of third annulus with very small precalcar or without it; serrula of second annulus much larger than other serrulae, with precalcar relatively close to postcalcar.
Head and thorax mostly covered with dense punctures (
Figs 3P
, 4M, N); punctures very often fused; interspaces generally narrower than diameters of punctures. Punctures on mesoscutellum much larger than those of mesoscutum. Abdomen microsculptured.
