Dawwrueng, N. Makbun, P. Pawangkhanant & K. Yimyoo. Diagnosis. This species differs from all known species of Terraplistes by: maxillary palps with apical, subapical and third segments completely black; first (basal) and second segments mostly black but distally white; male paraproct process with dorso-apical angle obtuse and ventro-apical angle more acute, very setose along apical margin. Description (n = 5). Habitus as typical for the genus ( Fig. 8 A). Frontal rostrum about 3.3 times broader than scapus. Maxillary palps with apical (fifth) segment elongated, moderately widened and apex strongly oblique; fourth segment with apical part slightly widened, third segment cylindrical; apical segment longer than third and fourth segments ( Fig. 8 B). Pronotum in male about 1.3 times longer than wide; with anterior dorsal margin concave, lateral margins slightly narrowed anteriorly, and posterior dorsal margin broadly rounded, covering tegmen completely. Hind femur about 1.6 times longer than hind tibia; hind tibia 1.5 times longer than hind metatarsus. Male. Last abdominal tergite and epiproct partly fused to a supra-anal plate; triangular, transverse at base and obtuse at apex; with a row of setae along margin ( Fig. 8 D). Cercus stout and fairly long. Subgenital plate broadly rounded. Paraproct process with club-like projection, separated from base by wide but shallow gap; projection fairly large, with dorso-apical angle obtuse and ventro-apical angle more acute, very setose along apical margin ( Fig. 8 E). Sclerotized structure in phallic complex absent. Female. Supra-anal plate setose, apical margin rounded. Subgenital plate triangular, about as long as wide, apical margin concave ( Fig. 8 F). Ovipositor short, with apical valves narrow; dorsal valve slightly longer than ventral valve; dorsal valve and ventral valve with apex acute, ( Fig. 8 G). Colouration. Generally black. Head black, eye brown; scapus and basal antennal segments black, antenna pale with black rings. Maxillary palps with apical, subapical and third segments completely black; first (basal) and second segments mostly black but distally white ( Fig. 8 B). Pronotum black ( Fig. 8 C). Mesosternum and metasternum black. Wing white ( Fig. 8 C). Legs, including tarsus, generally black. Hind femur with inner surface black; outer surface black with some brown scales. Hind tibia black. Abdominal tergites mostly black with scales along distal margins of tergites brown; abdominal sternites and subgenital plate black in male and dark brown in female. Cercus brown, more pale basally and darker apically ( Fig. 8 D). Ovipositor brown ( Fig. 8 G). Measurements. See Table 4 . Etymology. This species is named after Sigfrid Ingrisch, who has made immense contribution to the taxonomy of Mogoplistinae from Southeast Asia, including the erection of the genus Terraplistes .
