Description of male. Head. Longer than wide across eyes (1.02: 0.83); genae slightly notched anteriorly, reaching basal one-fourth of first antennal segment; clypeus strongly raised anteriorly, with tubercle near apex; antenniferous tubercles short, dilated, apices acute; antennae 2.47 times as long as width of head across eyes, length of antennal segments I to IV= 0.66: 0.33: 0.73: 0.33; eyes small, convex; postocular tubercles small and not reaching outer margin of eyes, postocular lobes strongly constricted posteriorly; vertex with irregular carinae flanked by a pair of large, ovate infraocular callosities.
Pronotum. 3.02 times as wide as long (1.48: 0.49), attenuated anteriorly; collar smooth and about as thick as diameter of first antennal segment (0.2: 0.17); anterolateral angles produced and forming blunt lobes; disc with a longitudinal median furrow, flanked by a pair of subtriangular plates which meet at anterior margin; laterally of plates disc with four (2+2) tuberculate callosities; laterally of callosities with a pair of subrectangular plates with strongly elevated granulate carinae; posterior margin of pronotum slightly convex separated from mesonotum by a deep furrow.
Mesonotum. Wider than pronotum (1.91: 1.48); separated from metanotum by a pair of very deep furrows; elongate subpentagonal median ridge across meso- and metanotum flanked by deep furrows and subtriangular plates with four (2+2) longitudinal callosities and granulate carinae along lateral margin.
Metanotum and mtg I+II. Wider than mesonotum (2.15: 1.91); median ridge flanked by a pair of deep oval excavations, laterally with a pair of oval plates with irregular longitudinal callosities, lateral margins granulate, like those of mesonotum; disc of mtg I with a pair of deep oval depressions sloping anterolaterally; disc of mtg II with a pair of deep furrows, sloping posteriorly and sideways, posterior margin carinate.
Abdomen.Tergal plate consisting of mtg III–VI, subquadrangular, posterior margin truncate, lateral margins slightly rounded; with a slightly raised median ridge on mtg III, a pentagonal elevation on mtg IV then tapering posteriorly; laterad of median ridge with usual pattern of large and small callous spots; deltg II+III completely fused, IV–VII separated by fine sulci; posterolateral angles formed by dorsally reflexed vltg II–VII progressively protruding; posterolateral angle of deltg VII subangulate; ptg VIII clavate, reaching to posterior margin of deltg VII; pygophore cordate (Figs.13–14); parameres slender (Figs.15–17).
Venter. Sterna III to VI raised along posterior margin, depressed along anterior border, and with triangular, smooth spots medially, flanked by a pair of large, transversely ovate shallow depressions, these bearing a pair of round callous spots of usual pattern; spiracles II to VII lateral and visible from above, VIII terminal; lateral rim of male vltg VII with a shiny callus anterior to spiracle VII.
Legs. Slender, preapical comb on fore tibia present, claws with fine pulvilli.
Female. Morphological structures as of male but of larger size. Head longer than wide across eyes (1.16: 0.92); length of antennal segments I to IV= 0.72: 0.36: 0.86: 0.36; pronotum wider than long (1.75: 0. 63); width of mesonotum 2.18; width of metanotum 2.51; across meso- and metanota median ridge strongly posteriorly elevated, irregularly rugose; mtg VII strongly elevated posteriorly; posterolateral angles of deltg VII blunt, ptg VIII lobiform, shorter than tergite IX; spiracles II to VII lateral and visible from above, VIII terminal.
Measurements [in mm, ♂♂ (n=24) / ♀♀ (n=14), holotype in parentheses]. Body length 5.1–5.5 / 5.9–6.7 (5.3); maximal width of abdomen 2.4–2.6 / 3.0–3.13 (2.6). Head length 0.99–1.06 / 1.09–1.19 (1.02), width 0.83– 0.86 / 0.89–0.96 (0.83). Pronotum length 0.49–0.53 / 0.56–0.59 (0.49), width 1.45–1.58 / 1.72–1.75 (1.48).
