Cleotomiroides vietnamensis Duwal & Yasunaga, sp. nov.

Cleotomiroides vietnamensis Duwal & Yasunaga sp. nov. (Figs. 4 ḠI, 6C, 9, 16B̄C) Diagnosis. Recognized by its larger sized body; yellowish brown hemelytron with apically smoky corium; distinct white fascia anteriorly on the hemelytron; pale or white areas on clavus and corium; pale appendages; and form of male genital structures. The new species is distinguished from congeners by the distinct coloration of dorsum and the form of male genital structures. It has a Cleotomiroides- type endosoma as described in Schuh, 1984, which is very close to C. spadix, but can be easily distinguished by presence of prominent spines on inner lateral side of apex of endosoma, and relatively wide proximal region of the apical process; and a distinct sub-apical protuberance (or spine) on the phallotheca. Description. Male. COLORATION (Fig. 4 ḠI): Dorsum yellowish brown; head uniformly pale yellow to yellowish brown including clypeus, mandibular plate, maxillary plates, and/ or entire ventral side of the head; antennal segments ĪII pale yellow, segment III brownish, and segment IV darker (in some specimens tinged red); labium brown except for pale yellow segment III; pronotum dark brown to blackish brown, anterior pronotum blackish, and basal margin and lateral corners of posterior pronotum pale; scutellum resembles coloration with posterior pronotum i.e., dark brown to blackish brown, with black margins; thoracic pleura dark brown to black with pale edge; scent gland evaporatory area brown to dark brown anteriorly and white or ivory posteriorly (Fig. 4 H); procoxa yellowish brown (red tinged in some specimen), meso- and metacoxae entirely pale; all trochanters whitish; all femora, tibiae and tarsus pale, with hind femur, meso- and metatibiae tinged red; hemelytron yellowish brown with darker base and apical 1/3 region; base of clavus blackish brown, followed by a white transverse fascia at level of apex of scutellum, and extended laterally to costal margin; subapical region of costa with large, more or less rounded, white spot; narrow region of posterior corium between white spot and cuneus, and lateral margins of cuneus smoky brown; membrane smoky brown, with white base, and basal margin distinctly dark brown; abdomen ventrally dark brown or blackish with pale basal segments, ĪIV. SURFACE AND VESTITURE: Head, pronotum and scutellum shiny; head and posterior pronotum smooth; anterior pronotum and scutellum rugose; hemelytron weakly shiny and shagreen. Head, pronotum, scutellum and cuneus with semierect simple pale setae; hemelytron and scutellum with erect long pale setae except for apical narrow region of corium, region behind posterior white spot of corium covered with semierect dark setae; antenna and legs with short semierect pale simple setae; and tibial spine pale, arranged in single row on hind tibia. STRUCTURE: Macropterous, body elongated. Head: Vertex weakly convex, with distinctly carinate basal margin; width between eyes narrow, shorter than length of antennal segment I; frons flat; eyes large, occupying almost entire height of head in lateral view; antennal fossae located above ventral margin of eye; antennal segments slender, with weakly thickened segment I, and length of segment II equal to width of basal pronotum. Thorax: Pronotum trapezoidal, with concave lateral margins; pronotal collar flat, narrow, shorter than width of base of antennal segment II; calli not demarcated; mesoscutum completely covered with pronotum; scent gland evaporatory area broadly triangular with distinctly elevated peritreme. Hemelytron: Width of hemelytron wide anterior to cuneal fracture; costal margin concave; cuneal fracture weakly incised, short and perpendicular to costal margin; basal width of cuneus nearly equal to length of the cuneus; larger cell of membrane angulated apically. Legs: Femora long and slender, hind femur somewhat thick apically; hind tibia weakly curved; tarsal segments I and II sub-equal in length, and segment III distinctly longer; pulvillus attached along claw, reaching midpoint of claw, parampodia weakly fleshy, and apically convergent. GENITALIA (Figs. 6 C, 9): Pygophore with a stout, relatively short spine sub-apically (Fig. 9 A). Right paramere broad sub-apically, and narrow apically to form thumb-like apical process (Fig. 9 E). Left paramere simple with elongated anterior and posterior processes, the anterior process tapered towards apex and posterior process somewhat broad sub-apically (Fig. 9 C̄D). Phallotheca broad basally and narrow apically, and furnished with a horn-like process sub-apically (Fig. 7 B). Endosoma, phyline type with complex apex and elongated apical process, the inner-lateral margin of apex with five spines, four large forming serrated surface, and one located slightly separate in distance and minute (Figs. 6 C, 9F). Female: The female resembles the male in color and vestiture, except for following characters: Body size slightly smaller in length; head width across eyes smaller; eyes small; vertex distinctly wide; antennal segment II relatively short; mesal length of pronotum short; width across hemelytron slightly wider. GENITALIA (Fig. 16 B̄C): Sclerotized ring elongated, thin rimmed, with wide base and narrow apex (Fig. 16 C). Anterior and vestibular sclerites of first gonophysis as in figure 16B. Measurements.
