Apical valves of penis long, divided, widened and lobed-like in median part, narrowed apically, almost as long as cingular valves (Fig. 5J); basal and apical penis valves connected by flexure.
Head and pronotum brownish grey; abdomen brown when alive (Fig. 6G), but fade to yellowish brown after preservation (Figs. 5A–B). Dorsal side of head dark brown; frons and genae dark brown (Fig. 5A); mandibles yellowish brown with brown apex (Fig. 5F). Antennae yellowish brown (Figs. 5A–B). Disc of pronotum and lateral lobes dark brown uniformly (Figs. 5A–B). Tegmina light brown (Fig. 5B). Fore and mid legs yellowish green. Hind femur yellowish brown with three black spots along the upper keel from basal to median part, and two indicting brownish spots near the apex (Figs. 5A–B); dorsal and ventral genicular lobes brown. Hind tibia green; dorsal spines with black apex. Hind tarsi light brown (Figs. 5A–B). 1 st and 2 nd abdominal tergites dark brown with large blackish spot on the median line between the apical part of 1 st tergite and basal part of 2 nd tergite, rest tergites brown. Supra-anal plate and paraprocts brown with dark brown small tubercles on dorsal surface of supra-anal plate; cerci light brown with brown banded near the middle; subgenital plate brown (Figs. 5A–B).
Female. Similar to male, but distinctly larger and bulge body. Head slightly shorter than the pronotum (Figs. 5D–E). Frons and genae coarsely punctured; vertex and occiput punctured except median part smooth. Face in profile reclinate (Fig. 5D). Frontal ridge distinct to median ocellus, deeply sulcated between the antennae, slightly narrowed near median ocellus. Vertex between eyes slightly broader than maximal width of frontal ridge. Fastigium of vertex rather long; foveolae present (Fig. 5D). Eyes large, almost spherical. Antennae 23-segmented. Pronotum punctured, crossed by three transverse furrows and one short transverse furrows between the first and the third furrows, pronotum constrict at the median half in dorsal view (Figs. 5D–E); median and lateral carinae absent; prozona 2.5–2.6 times as long as metazona; anterior margin of pronotum subtruncate; posterior margin of pronotum nearly truncate with shallow excise on the middle (Fig. 5E).

Tympanum rather large, oval, covered by tegmina. 6 th and 7 th abdominal sternites with two subparallel rows of hairs. 10 th abdominal tergite with paired of small lobes on posterior margin; supra-anal triangular with shallow median groove, longer than width near base (Fig. 5P). Cerci slightly beyond the supra-anal plate, conical, with obtuse rounded apex, 2.3–2.5 times as long as their width near base (Figs. 5Q–R). Subgenital plate 1.6–1.7 times longer than wide, apical part triangular with acute apex (Fig. 5R). Ovipositor short, dorsal valves thicker and longer than ventral valves, both valves smooth margins, dorsal valves slightly curved upward, but ventral valves almost straight (Figs. 5Q–R).
When alive (Fig. 6H), head with greyish dorsally, yellowish stripe behind the eyes longitudinal and continue to the pronotum; frons and genae brown; postocular grey. Antennae light brown with darker near apical part. Disc of pronotum dark brown and separated from lateral lobe of pronotum by the broad yellowish stripe that connect from the stripe behind the eyes, lateral lobe with blackish upper half and yellowish brown with scattered dark brown spots on lower half; blackish spots along both anterior margin and posterior margin of pronotum. This coloration could be faded after preservation and hard to see in dried specimens (Figs. 5D–E). Tegmina light brown. Fore and mid femur light brown with small blackish spots; fore and mid tibia brown with small blackish spots. Hind femur with the same coloration and spots presented on the male, but inner side orange brown. Hind tibia brown, dorsal spines with black apex. All tarsi light brown. Abdominal tergites brown with small black spots on the posterior margins except 10 th abdominal tergite. Supra-anal plate and paraprocts brown; cerci light brown. Sternites and subgenital plate light brown. Ovipositor light brown (Figs. 5D–E).
Measurements (length in mm). Body: male 17.1, females 20.8–22.1; antenna: male with apical part broken, females 10.7–13.5; pronotum: male 3.2, females 4.4–4.6; tegmen: male 2.5, females 3.6–4.2; hind femur: male 10.4, females 13.2–14.6.
Diagnosis. The new species is easily distinguished from congeners by follows combination of features: the coloration (dark brown to yellowish brown), the shape of tegmina (widened); furculae on 10 th abdominal tergite of male (distinctly long); shape of male supra-anal plate (lateral margin distinctly constricted and form a small tubercles); male paraprocts (with small rounded tubercles); genital complex (long and bent upward valves of cingulum, blunt shape of epiphallus); female abdominal sternites (two row of hairs presented of 6 th and 7 th rows sternites); and female subgenital plate (triangular with acute apex).
Etymology. The specific epithet from the Latin word “maculatus” which gave the meaning “spot” for the presented of blackish spots on the hind femur in both sexes and on abdominal tergites in female.
Distribution. Thailand (Chiang Rai Province).
