Material examined. Holotype—male, Thailand: Surat Thani Province, 40 km SW of Phanom City, environs of National park Khao Sok, 6 November 2010, coll. D. Gapon (ZISP).
Description. Body medium-sized for the genus. Antennae filiform, 14-segmented, 1.7 times as long as the fore femur; middle segments (7–9th) 6.0–6.5 times as long as wide. Antennal sockets situated between the lower third of the eyes. Fastigium of the vertex as wide as one eye seen from above; medial carina of the fastigium short; tranverse carina in frontal view U-shaped; supraocular lobes distinct. Eyes not protruding above the pronotum in lateral view. Lateral ocelli situated slightly above the middle of the eyes. Frontal ridge broadly rounded in lateral view. Width of the frontal ridge near the base of the antennae 0.6 times the width of the 1st antennal segment. Pronotum in dorsal view with a straight anterior margin; posterior process of the pronotum not reaching the apex of the hind femora. Median carina of the pronotum in profile low, almost straight. Lateral carinae in the prozona well defined and slightly incurved posteriorly; prozona transverse, its width 1.3 times its length. Disc of the pronotum gently depressed near the humeral angles, with a pair of long interhumeral carinae; posterior process of the pronotum with few tubercles. Hind margin of the lateral lobes of the pronotum with a tegminal (upper) sinus as deep as the lower sinus; lower side of the lateral lobes of the pronotum in dorsal view triangular. Tegmina ovate, with rounded apex; visible part of the tegmen 2.8 times as long as wide; width of the visible part of the tegmen 0.8 times the width of the mid femur. Hind wing almost not reaching the apex of the posterior process of the pronotum. Upper and lower sides of the fore and mid femora straight and weakly serrate. Fore femur 3.8 times, and mid femur 3.2 times as long as wide. Upper and lower side of the hind femur almost smooth. Hind femur 3.2 times as long as wide. Upper side of the hind tibia with 8–9 outer and 4–5 inner teeth. First tarsal segment of the hind leg 1.2 times as long as the 3rd segment (without claws); ventral side of 1st segment with 3 pointed pads, apical pad distinctly longer than the other pads; 3rd segment not swollen. Epiproct triangular, with a pointed apex. Subgenital plate elongated, 1.2 times as long as wide, posterior margin of the plate excised near the middle. Cerci conical, with pointed apices, twice as long as wide near the base.
Head dorsally uniform brown; eyes light brown; ocelli shining brown; antennae brown. Genae and frons light brown with indistinct blackish marks; labrum shining black with two light spots; mandibles and maxillary palpi pale brown. Disc of pronotum brown with indistinct dark brown marks; lateral lobes of pronotum brown with blackish marks. Visible part of the tegmina blackish brown. Anterior margin of hind wings blackish. Fore and mid femora brown. Fore and mid tibiae brown with 3 light brown rings. Fore and mid tarsi black, but the base of 2nd segment brown. Hind femur light brown with few indistinct dark brown spots on outer side; lower part of femur black. Hind tibia blackish brown. All tarsal segments of hind leg brown. Tergites and epiproct brown with blackish marks. Sternites pale brown. Subgenital plate light brown with blackish apex. Cerci brown.
Female unknown.
Measurements (mm). Length of male body 8.5; antenna 2.9; pronotum 7.9; tegmen 1.4; fore femur 1.7; mid femur 1.9; hind femur 6.0.
Distribution. Thailand (Surat Thani Province).
Diagnosis. The new species is similar to Cotysoides albipalpulus Zheng et Jiang, 2003 from China (Guangxi) in the shape of the body and the relatively short pronotum, but differs from the latter in the shape of median carina of the pronotum and in the colour of the hind tibia (in C. albipalpulus the median carina in profile sinuate and the hind tibia are black with two light rings).
Etymology. The new species is named after his collector Dr. D.A. Gapon.
