Measurement. BL= 3.25–4.03 mm; FBL= 1.75–1.80 mm; HL= 0.41–0.47 mm; HWE= 0.69–0.75 mm; HWT= 0.66–0.77 mm; EL= 0.13–0.22 mm; TL= 0.19–0.30 mm; ETR= 0.81–1.22; PNL= 0.45–0.55 mm; PNW= 0.79–0.81 mm; PNR= 0.56–0.68; ABDW= 0.80–0.88 mm. Description. Body yellow, elytra darker, head brown, shining, forebody with dense and small punctures.
Male: Head (Fig. 4–1C) near rectangular, as broad as pronotum. Clypeus convex, smooth, with small punctures, anterior martin slightly curved forward. Epistomal suture with lateral portions running backward to level of anterior margin of eyes. Front of head bordered by fine ridge. Post-ocular furrow marked, reach to base of head. Disc with dense small punctures, sides with deep longitudinal furrow, depressed at anterior 1/3, flat at basal 2/3 carrying denser and bigger punctures. Temples dilated, with big punctures, about 1.2 times as long as eyes. Eyes big. Occipital furrow complete and curved forward. Antenna filiform, VI-X with basal ridges.
Pronotum (Fig. 4–1C) trapezoidal, broadest at near 1/2, convex in middle, with dense punctures and less furrows. Mid-longitudinal sulcus broad and shallow, narrower and deeper at posterior 1/3, with two shallower and poorly defined paramedial sulci and two para-lateral depressions close to lateral margins. Posterior angles obvious and sharp. Sides running continuously and constricted at posterior 1/4. Elytra with punctures and furrows. Abdomen without puncture.
Sternite VII (Fig. 4–1E) with posterior margin slightly emarginate and carrying long setae laterally, with two small tubercles in middle; Sternite VIII (Fig. 4–1F) with posterior margin broadly bi-emariginate and carrying long setae laterally, obtused angulate in the middle, not beyond lateral angles posteriorly.
Aedeagus (Figs 4–1H–J, 4–2A–C) oval, inflated at base and shortly narrowing to apex; apical orifice large and ventral orifice crescentic. Parameres (Figs 4–1K, 4–2H) arm-like, closely situated, broader at anterior 1/3 carrying row of setae, penicillate at apex; with large seta at middle of ventral edge on each piece.
Female. Head (Fig. 4–1D) narrower than pronotum (Fig. 4–1D). Punctures of pronotum lesser and bigger than male. Temples not dilated, about 0.8 times as long as eyes. Sternite VII with posterior margin almost straight and unmodified. Sternite VIII (Figs 4–1G, 4–2G) with posterior margin produced, broadly and obtusely triangular. Spermatheca (Fig. 4–1N) with base bulb-like, with apical part clavate and slightly curved.
Distribution: China (Guangxi).
Etymology. The specific epithet derived from two Latin words, declivis and sculptilis, to indicate the obliquely arranged scultptures in the posterior and lateral part of the head.
Differential diagnosis. This new species can be distinguished by the following characters: head flat near base and with post-ocular furrow reach to base; pronotum constricted near base and with posterior angles sharp; mid-longitudinal sulcus of pronotum broad and shallow at anterior 2/3; paramere penicillate at apex; structure and relative position of internal sac selerites (Fig. 4–2C–D).
