Cleotomiris inthanon Duwal & Yasunaga sp. nov.

(Figs. 4 ĀC, 6A, 7)

Diagnosis. Recognized by its larger sized body; black pronotum and scutellum; brownish hemelytron, femora and tibiae; a distinctly white transverse fascia across clavus and corium, and pale areas on corium (Fig. 4 ĀB); orientation of two subapical spines of phallotheca (Fig. 7 B); short and broad anterior process of left paramere (Fig. 7 D̄F); elongated apical process of right paramere (7C); and short endosoma with long slender apical process, with lanceolate distal region (Figs. 6 A, 7ḠH).

The new species is easily distinguished from Cleotomiris schneirlai by its larger size. Although it is similar in size, coloration and vestiture pattern to C. yamadakazi, or, C. levigatus, C. inthnon can be easily separated by the entirely pale meso- and metacoxae. The most distinctive characters are exhibited in the male genitalic structures, i.e., sub-apical spine of pygophore is relatively short (Fig. 7 A); orientation of sub-apical spines, or processes on phallotheca (Fig. 7 B); anterior process of left paramere short and broad (Fig. 7 E); and slender apical process of endosoma with lanceolate distal region (Fig. 7 ḠH).

Description. Male. COLORATION (Fig. 4 ĀC): Dorsum brown; head black, dark brown vertex basally with black margin; clypeus brown with dark base and apex; mandibular plate, maxillary plates and ventral side of head dirty yellowish; baccula whitish; eyes black with red marginal edge; antennal segment I yellowish with pale extreme base and dark ring apically, segment II brown gradually darkened towards the apex, and segment III dark brown with paler base; segment IV missing; labium dirty yellowish brown with darker apical segment; pronotum and scutellum black, with pale basal margin of pronotum and apex of scutellum; pleura black with brown edge; scent gland evaporatory area anteriorly yellowish brown and posteriorly whitish, with dark (blackish) peritreme; procoxae blackish brown, meso- and metacoxae, and all trochanters pale; femora, tibiae, tarsus brown with slightly paler bases of meso-, and metafemora; hemelytron brown with darker apical costa and lateral margins of cuneus, and corium and clavus with contrastingly white or pale areas: claval fascia white located behind apex of scutellum and transversely extended to endocorium (Fig. 4 A), corium near sub-apical region of costa bears pale brown spot, and areas at level of apex of clavus relatively paler; membrane smoky brown with white base; abdomen brown with darker anterior margins. SURFACE AND VESTITURE: Head, pronotum and scutellum weakly shagreen, anterior pronotum slightly rugose; hemelytron entirely dull. Dorsum covered with mixture of sparsely scattered long erect pale setae and densely distributed with recumbent pale shining setae; hemelytron also bears simple recumbent brownish setae; all appendages covered with short, semierect simple setae and scattered long erect pale spines. STRUCTURE: Macropterous, body remarkably enlarge and elongate. Head: Vertex weakly convex, flattened, with weakly carinate narrow basal margin; frons flat; eyes large, width of head across eyes as long as length of pronotum, and eyes occupying almost entire height of head in lateral view; antennal fossa located slightly above ventral margin of eye; antennal segment I short and diameter smaller than apex of segment II, apex of segment II thickened, and segment III somewhat stout and spindle shaped; and labium slightly surpassing apex of mesocoxae. Thorax: Pronotum trapezoidal, with concave lateral margins; collar narrow, flat; calli flat and not demarcated; scent gland evaporatory area triangular, with distinctly elevated peritreme. Hemelytron: Laterally sub-parallel; costal margin weakly concave in basal 2/3 region; cuneal fracture weakly incised, short and perpendicular to costal margin; larger cell of membrane angulated. Legs: Femora long, slender, lateral margins nearly parallel with slightly narrow apices; tibia somewhat stout and long; tarsal segments in hind legs missing; pretarsal segments of middle leg, claw curved, pulvillus attached along the claw reaching midpoint of the claw, and parampodia weakly fleshy and convergent apically. GENITALIA (Figs. 6 A, 7): Pygophore small and trapezoidal with short and stout spine sub-apically (Fig. 7 A). Right paramere lanceolate with elongated apical process (Fig. 7 C). Left paramere with short and broad anterior process, and long and slender posterior process (Fig. 7 D̄F). Phallotheca narrow towards apex, with two stout spines sub-apically (Fig. 7 B). Endosoma short and stout, with secondary gonopore enlarged, and the apical process very long, slender and twisted with lanceolate distal region (Figs. 6 A, 7ḠH).

Female: Unknown.

Measurements. (♂) (n= 1). Body length 3.80; length from apex of tylus to cuneal fracture 2.62; width of head across eyes 0.70; width of vertex 0.25; lengths of antennal segments ĪIV 0.35, 1.05, 0.48,?; length of labium 1.39; mesal length of pronotum 0.70; basal width of pronotum 1.20; width across hemelytron 1.19; length of metafemora, tibiae and tarsus 1.21, 1.74,?.

Etymology. Named after the highest mountain “Doi (=Mt.) Inthanon ” in Thailand, type locality of this new species; a noun in apposition.
