( Figs. 1 View FIGURE 1 A –B, 4, 5, 7)

Diagnosis. Readily distinguished from any other congeners by its fuscous, rather elongate, antlike body, nearly matt dorsal surface, two dark stripes on the antennal segment I, very short and sparse scalelike setae on hemelytron, a ventral, mesal keel on male genital segment, and both noticeably long, flagellum and a median spine on endosoma.

Description. Male: Body generally fuscous, rather elongate, antlike, moderately constricted (HCR = 0.67); dorsal surface matt, weakly shining, with sparsely distributed, short, silky, semierect setae. Head triangular in frontal view. Antenna dark brown; segment I creamy yellow, with two dark reddish brown stripes dorsally; segment III weakly incrassate toward apex; basal half of segment III and extreme base of IV yellowish white. Labium shiny chocolate brown, broad, exceeding procoxa but not reaching base of mesocoxa. Pronotum weakly constricted anteriorly; pleura uniformly pruinosed or shagreened; scutellum somewhat swollen, with uniformly distributed, reclining, silvery, scalelike setae. Hemelytron with a short fascia composed of rather long scalelike setae on median part of corium and a confluent posterior fascia with very short, scalelike setae; membrane dark smoky brown. All coxae and trochanters creamy yellow, except for apical half of mesocoxa dark reddish brown; profemur yellowish brown, with a dark, dorsal stripe at apical 2 / 3; meso- and metafemora dark brown, except for yellow extreme bases; all tibiae dark brown, except for apical halves of pro- and mesotibiae and apical 1 / 3 of metatibia pale reddish brown; tarsi pale brown; tarsomeres III brown. Abdomen shiny fuscous; genital segment ventrally with a keel mesally. Male genitalia ( Figs. 5 View FIGURE 5 , 7 View FIGURE 7 ): Left paramere with a slender, dorsal protuberance. Endosoma elongate, rather strongly curved, nearly J-shaped, with a subapical spine and a long flagellum. Female: Unknown.

Measurements. ♂: Total body length 3.3; length from apex of clypeus to cuneal fracture 2.62; width of head across eyes 0.80; head height 0.78; width of vertex 0.34; lengths of antennal segments I −IV 0.24, 1.06, 0.30, 0.35; basal width of pronotum 0.84; minimum width across hemelytron 0.68; maximum width across hemelytron 1.02; and length of metatibia 1.72.

Etymology. Named after the wife of the third author, Suwimon, who supported a recent survey in Chaiyaphum Province.

Biology. Unknown.
