Diagnosis. This species can be easily separated from all other Anisoderomorpha species by the following characteristic: elytra dark green with metallic luster.
Description. Male. Body length = 15.55 mm. Elytral length = 10.66 mm.
Coloration almost brownish red; antennae and legs black; elytra dark green with metallic luster.
Head (Fig. 15) almost symmetrical, with microscopic setae. Clypeus rounded, asymmetrical, dilated on right side of anterior margin, delimited by a transverse impressed line. Eyes strongly prominent. Maxilla rather feebly chitinous, the inner lobe armed with three minute blunt teeth at the tip. Mandibles slightly asymmetrical (length: 1.38 mm for left; 1.18 mm for right). Antenna (Fig. 16) with 5-segmented club; antennomere III> II> IV = V = VI; VII dilated terminally, as long as wide; VIII dilated terminally, distinctly wider than VII, as wide as IX and X; IX and X strongly transverse; XI trapezoidal-ovate, transverse, a little narrower than X.
Pronotum (Fig. 17) subquadrate, slightly longer than wide, convex in front, feebly narrowed from the front to the hind margin; lateral side slightly arcuate, slightly sinuate just before posterior angles; basal margin only slightly arched posteriorly at median part; posterior angles slightly projected. Prosternal process (Fig. 18) forming a rounded deflexed lobe behind the coxae. Metaventrite acutely notched between the hind coxae, with a deep groove along the midline.
Scutellar shield (Fig. 19) as long as wide. Elytra (Figs. 13, 19–21) very straight; the intervals rugulose and minutely, rather closely punctured; apical margins evenly rounded. Tibiae smooth. Tarsi (Figs. 13, 14) moderately dilated and fairly long. Abdominal ventrites 1–4 with a deep pit on each side.
Male terminalia. Sternite VIII (Fig. 23) parallel-sided; posterior part closely pubescent and punctate; apical margin concave; basal margin V-shaped. Tegmen (Fig. 24) ventrally with a pair of sclerotized ridges in middle, enclosing penis; parameres distinctly asymmetrical in length, flattened, stout, with long setae at apical part. Penis (Figs. 25, 26) long, flat, curved laterally; narrowed apically, produced and rounded at the apex; penile struts as long as the length of median lobe excluding penile struts.
Female. Body length = 13.56–21.40 mm (n = 5). Elytral length = 9.09–14.50 mm (n = 5).
Female similar to male in general appearance except for the following characters:
Head (Fig. 30) very large, distinctly asymmetrical. Genae dark red to black. Eyes smaller than in male, slightly prominent. Mandibles distinctly asymmetrical (mean length ± SD = 2.57 ± 0.55 mm, range = 1.95 to 3.14 mm, n = 5 for left; 1.61 ± 0.32 mm, range = 1.27 to 1.98 mm, n = 5 for right). Pronotum (Fig. 32) inverted-trapezoid, large, as long as wide; lateral side strongly arcuate, sinuate just before posterior angles; basal margin protruded outwardly at the median part; posterior angles distinctly projected. Prosternal process (Fig. 33) wider than in male. Scutellar shield (Fig. 34) wider than long. Protarsi (Figs. 28, 29) much wide. Mesotarsi (Figs. 28, 29) wide.
Female terminalia. Sternite VIII (Fig. 38) parallel-sided; posterior part closely pubescent and punctate; apical margin strongly concave; basal margin strongly V-shaped. Ovipositor (Figs. 39, 40) straight, long, narrow. Gonocoxite acute; lateral side slightly arcuate at basal part; right gonocoxite rather longer than left one; setae present near stylus. Stylus (Fig. 39) short, with long setae, located subapically. Spermatheca (Fig. 41) curved and elongate, with apex spherically expanded.
Etymology. The new species is named after the type locality, Tam Dao, Vinh Phuc Province, Vietnam.
Distribution. Vietnam (Tam Dao).
