Description.

Length, male, pronotum: length × width: 5.5 × 6.0mm, tegmen 18.5-19.0mm; overall length (including tegmen) 24.0mm. Body yellowish brown (Figs 9, 56-58). Antenna pitch-black except apex of flagellum reddish brown. Labrum, maxillary palpus and labial palpus pitch-black. Pronotum yellowish brown with dark brown maculae at disc (Figs 9, 47). Tegmen pale reddish brown and apex blackish brown (Figs 9, 56-58); wing pale brown with inner and apical margin blackish brown (Fig. 49). Legs yellowish brown, tibiae and tarsi blackish brown (Fig. 10).

Vertex with interocular space wider than distance between antennal sockets, and ocellus width about same as distance between antennal sockets. Third and fourth maxillary palpomus about same length, both distinctly longer than the fifth. Pronotum nearly trapezoid with shallow U-shaped macula near base, and hind margin distinctly curved (Figs 9, 47, 56-58). Tegmen with apical posterior branch of radius vein unbranched; median vein also unbifurcated (Fig. 48). Hind wing with radius vein branched beyond the middle, median vein simple, cubitus with 2 complete and 3 incomplete branches, and triangular apical area reduced and small (Fig. 49). Middle of the first abdominal tergite elevated, with a tuft of hair directed forward, T7 and T9 unmodified (Fig. 50).

Male genitalia. Supra-anal plate (Fig. 51) symmetrical, hind margin truncate and turning ventrad. Paraprocts dissimilar, right one bearing a long spine-like process and a hand-like process on distad; left one with a spine-like process distad (Fig. 51). Sub genital plate (Fig. 52) asymmetrical, hind margin produced in the middle, right stylus arising at apex and left stylus spine-like directed downwards near base of right one, right side with an irregular sclerite with apex is serrated. Hook-like phallomere on the left (Fig. 53), median phallomere with tapering apex (Fig. 54); right phallomere with lots of irregular sclerites and one of them with slim setae (Fig. 55).

Female is similar to male. Supra-anal plate symmetrical, triangular; subgenital plate broad, hind margin slightly arced, near lateral sides concaved.

Remarks.

This species resembles Symploce striata , but can be differed by the following characters: 1) pronotum with shallow U-shaped macula, without macula in Symploce striata ; 2) apex of tegmen with blackish brown macula, without macula in Symploce striata ; 3) terminal half of subgenital plate distinctly triangular, trapezoidal in Symploce striata .

Etymology.

The specific name is derived from the Latin adjective “evidens”, referring to the pronotum with an evident shallow U-shaped macula.
