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.
