(Figs. 1–17)
Material examined: Holotype male labelled: Vietnam, Haiphong / Catba, 200m / N 20°42’, E 106°53’ / 5 X 2011, Bai & Pham leg. // deposited in CAU; paratypes: 4 males, 6 females collected with holotype (CAU, CEHI); these types are designated and labelled accordingly.
Description. Holotype, male; coloration reddish to blackish brown; eyes reddish;
body structures except median parts of pro-, meso-, metasternum and vltg II–VII densely covered with setigerous tubercles; antennae and legs beset with many erect setae. Head. Genae exceeding clypeus, reaching to 2/3 of first antennal segment and leaving a small notch at apex, lateral margins constricted; clypeus raised; antenniferous tubercles dentiform, divergent anteriorly; antennae 1.57 times as long as width across eyes; vertex with wide longitudinal tuberculate ridge flanked by 2 (1+1) small callous pits; rostrum not reaching limits of rostral groove, rostral groove deep and narrow, closed posteriorly.
Pronotum. More than 3x as wide as long at midline; anterolateral angles slightly angularly expanded not reaching collar, lateral margins with many setigerous tubercles; disc with a median longitudinal granulate ridge, flanked by 2 (1+1) smooth oval callous depressions and 2 (1+1) lunate granular carinae laterally; posterior margin sinuate. Mesonotum. Scutellum distinct, disk with a wide median granulate ridge; anterolateral angles not reaching lateral margins of anteriorly produced wing pads; these oval, lateral margins granulate and elevated; posterior margin convex; suture separating metanotum bisinuate.
Metanotum. Fused to mtg I, with a triangular median elevation, interrupted posteriorly by a shallow median depression; lateral sclerites sloping toward lateral margins; posterior margin slightly concave.
Abdomen. Surface granulate, lateral margins slightly rounded with erect setae; tergal disk elevated along midline as high as metanotal elevation; fused mtg II with 2 (1+1) oval elevations depressed at middle; rounded ridge of mtg III–VI with distinct scent gland openings; lateral parts sloping with usual pattern of apodemal impressions; mtg VI narrow, sloping posteriorly; deltg II–VII separated by sutures, surface granulate; tergite VII raised posteriorly for reception of pygophore.
Venter. Prosternum with median elevation, separated from mesosternum by a suture, posterior borders of propleura with oblique tuberculate carinae, visible from above; meso- and metasternum flattened medially, with shallow longitudinal impression; vltg III–VI with smooth triangular spots medially, flanked by the 1+2+2 pattern of apodemal impressions; mst VII transversely carinate posteriorly; spiracles II–VII ventral, remote from lateral margin, VIII lateral and visible from above.
Genitalic structures. Pygophore globular, median triangular elevation extending posteriorly (Figs. 3–5); ptg VIII small, shorter than pygophore; parameres as in Figs. 6–8; phallus as Figs. 9–11.
Legs. Slender, femora moderately inflated, tibiae cylindrical, nearly straight, preapical comb on fore tibia present, claws with thin pulvilli.
Female. Generally as male but of larger size and more rounded abdomen; tergite VII roundly elevated, ptg VIII triangular, shorter than produced tricuspidate tergite IX+X.
Measurements. Holotype male: length 4.5; length / width of head 1.0/1.15; l/w pronotum 0.5/1.6; l/w scutellum 0.4/1.4; length of antennal segment I/II/III/IV = 0.5/0.35/0.5/0.45; ratio length of antennae / width of head 1.57; width of abdomen across tergite IV 2.3. Variation of size in paratypes: males 4.2–4.5; females 4.9–5.0.
Etymology: The specific name refers to the long tergal plate anteriorly produced because of the fusion with mtg II.
Distribution: So far only recorded from northern Vietnam (Catba).
