Diagnosis.

This new species resembles Sarimodes taimokko Mastumura, but differs from the latter by 1) frons with median carina distinct at upper half, in Sarimodes taimokko , frons with median carina distinct at basal third; 2) genital style with hind margin almost straight, in Sarimodes taimokko , genital style with hind margin weakly concave near middle; 3) phallobase with dorsolateral lobe bearing a pair of long clavate processes near apex, aedeagus with a pair of curved hooks at middle, in Sarimodes taimokko , phallobase with dorso lateral lobe bearing a pair of short triangular processes, aedeagus each with two processes, inner one slightly short.

Description.

Male length (n = 4) (including tegmen): 7.6-7.9 mm, length of tegmen: 6.6-6.9 mm; female length (n = 3) (including tegmen): 8.8-9.5 mm, length of tegmen: 7.8-9.5 mm.

Coloration. Body fulvous with fuscous maculae. Vertex yellowish brown. Eyes black brown. Frons fuscous with pale tubercules at black lateral area. Clypeus brown with two dark lateral fascia. Rostrum dark brown and black at apex. Ocelli yellowish brown. Pronotum and mesonotum yellowish brown. Tegmen fulvous with fuscous and yellow speckles. Hind wing brown, veins fuscescent. Leg fulvous with fuscous transverse stripes, tips of teeth black (Figs 17-19). Abdomen fulvous and fuscous medially.

Head and thorax. Vertex hexagonal, 1.2 times longer than wide in middle line, anterior margin angulately convex at middle, posterior margin deeply angulately excavate (Fig. 17). Frons slightly longer than wide, upper margin distinctly concave, with median and sublateral carinae present at upper half of frons (Fig. 18). Clypeus smooth with disc slightly convex. Rostrum reaching post-trochanter. Pronotum almost as long as vertex, with anterior margin acutely convex, posterior margin nearly straight, only shallowly emarginate at middle, median carina distinct (Fig. 17), paranotal lobe smooth, ventral margin oblique and straight, lateroventral angle subacute (Fig. 18). Tegmen elongate, 3.1 times longer than wide at widest part at basal third (Fig. 19). Hind wing with single transverse vein in between R and M and between M and CuA1 respectively; CuA2 and CuP fused from one third of CuA2 to apex, the fused part relatively thin and long (Fig. 20). Metatibiotarsal formula 2+7/9/2.

Male terminalia. Anal segment cyathiform in dorsal view, 2.1 times longer than widest part, lateral margin weakly widened at base, apical margin weakly concave at middle (Fig. 25). Phallobase with dorsolateral lobe bearing a pair of long clavate processes near apex, ventral lobe with apical margin acutely convex; aedeagus with a pair of curved hooks at middle (Figs 23, 24). Genital style in lateral view subtrianglar, hind margin almost straight, caudo-ventral angle slightly convex (Fig. 22). Capitulum short and wide, with a very small lateral tooth (Fig. 21).

Female terminalia. Anal segment elongate, nearly oblong in dorsal view, 2.5 times longer than widest part, apical margin slightly convex; anus short, situated at base of anal segment (Fig. 26). Gonoplac with apical margin oblique and convex at dorsal half, disc elevated near base in dorsal view, fork faintly pigmented (Figs 27, 28). Proximal part of posterior connective lamina of gonapophyses IX strongly convex in lateral view, median field single lobed, lateral fields obtusely bent at distal part (Figs 29, 30). Anterior connective laminae of gonapophysis VIII broad, ventral margin straight, bearing one tiny tooth near apex, apical group with three short stout teeth, with three keeled teeth in lateral group (Fig. 31). Sternum VII with posterior margin nearly straight at middle (Fig. 32).

Etymology.

The specific epithet is derived from the Latin word “clavatus”, referring to dorso-lateral lobe of phallobase having a clavate process in lateral view.

Distribution.

China (Hainan).
