Type material.

Holotype: male, China, Hainan Province, Jianfengling Mountain, 27 May 1983, coll. Maobin Gu.

Diagnosis.

This new species resembles Sarimodes clavatus sp. n. in the present paper, but differs from the latter by 1) frons approximately 1.25 times wider than long in middle line, in Sarimodes clavatus , frons slightly longer than wide; 2) genital style with hind margin produced near apex, caudo-ventral angle strongly convex, in Sarimodes clavatus , genital style with hind margin almost straight, caudo-ventral angle slightly convex; 3) aedeagus with a pair of hooks semicircularly curved, in Sarimodes clavatus , aedeagus with hooks almost straight, slightly curved dorsally at apex.

Description.

Male length (n = 1) (including tegmen): 6.8 mm, length of tegmen: 5.8 mm.

Coloration. Generally brown with pale brown carinae and dark brown maculae. Vertex yellowish brown with black brown spots. Eyes dark brown. Frons dark brown with pale brown tubercules, near lateral and apical margins black. Gena yellowish brown with dark macula in front of eyes. Antenna with scape pale brown, pedicel brown with pale sensory pits. Clypeus yellowish brown with dark brown longitudinal stripes. Tegmen brown. Hind wing yellowish brown. Leg brown, base and apex of fore and mid femora and tibiae with dark brown band, and base of hind femora dark brown, tips of teeth black. Abdomen ventrally and dorsally brown, disc dark brown (Figs 33-35).

Head and thorax. Vertex nearly hexagonal, approximately 2 times wider than long in middle line, anterior margin weakly angulately convex at middle, posterior margin distinctly obtusely concave (Fig. 33). Frons approximately 1.25 times wider than long in middle line, upper margin moderately concave, with median carina present at basal half, with a row of submarginal tubercules (Fig. 34). Pronotum narrower than head combined with eyes, longer in middle line than vertex, median carina distinct, with several small tubercules at lateral area (Fig. 33); paranotal lobes lamelliferous, with three small tubercles along posterior margin, ventral margin moderately oblique (Fig. 34). Tegmen approximately 3.2 times longer than widest part (Fig. 35). Hind wing with single transverse vein in between R and M and between M and CuA1 respectively; CuA2 thoroughly fused with CuP, the fused part relatively thick and short (Fig. 36). Metatibiotarsal formula 2+7/8/2.

Male terminalia. Anal segment elliptical, 2.9 times longer than widest part near base, apical margin obtusely convex (Fig. 37). Phallobase with dorsolateral lobe bearing a pair of spiniform processes near apex, directing cephalad, ventral lobe with apical margin weakly concave medially; aedeagus with a pair of almost straight hooks at middle (Figs 40, 41). Genital style with hind margin obtusely convex near apex, caudo-ventral angle strongly convex (Fig. 38). Capitulum short, with posterior margin sinuate, apex pointed, with triangular lateral tooth (Fig. 39).

Etymology.

The specific epithet is derived from the Latin word “parallelus”, referring to the pair of ventral hooks of aedeagus being nearly parallel in ventral view.

Distribution.

China (Hainan).
