Bresseel (I.G.: 32.161)— 2 females, 3 males( Brussels RBINS).   Diagnosis.Males of  C. panitvongican be recognized by the ninth abdominal tergite having a large groove on posterior surface with bulging margins but without distinct dorsal lobe, the lateral projections are nearly rectangularly bent from the broad base to the rather short acute spine while the pair of projections of the tenth tergite are long and thin with the base rather faintly swollen. The females have the basal area of the seventh abdominal sternite distinctly sclerotised, strongly setose in middle and concavely opening behind to a pair of large oval grooves at the beginning of the membranous zone; the subgenital plate is tongue-shaped. Beside of the color morph with a hieroglyphic figure on pronotum as described in Gorochov et al. (2015), there is also a morph with a large black spot on pronotum including four light dots. Additional Description.Medium sized species. Head: Face oval; nearly smooth; fastigium verticis wider than scapus; ocelli little distinct; fastigium frontis separated from fastigium verticis by a very fine suture; subocular furrows shallow ( Figs. 55G–H). Abdominal tergites two and three each with two rows of stridulatory pegs (1–7, 8– 13; 13–18, 9–22; n = 3 males, 2 females). Wings reaching or little surpassing end of stretched hind tibia ( Figs. 54F–I). Tegmen: Radius with two branches, both forked near tip; media anterior free, in subbasal area closely approached to radius, usually unbranched but in some specimens dividing into 2 branches; cubitus anterior at base with a single branch that forks into two veins, the anterior branch makes a curvature and often receives an oblique connection vein from MA and shortly after divides again into two parallel branches, MP and CuA1, while the posterior branch (CuA2) does not divide further; cubitus posterior undivided, free throughout; with 4 anal veins, last two with common stem. Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; hind femur with 6–7 external and 5–7 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine; with 3 apical spurs on both sides. Coloration. General color light brown; vertex uniformly light brown or with a black band from behind compound eye along anterior area of fastigium verticis to other side, in another color variant vertex black, on fastigium verticis alternating with 3 brown bands; pronotum with a black figure on disc consisting of anterior and posterior transverse bands connected by 3 distinct or indistinct longitudinal bands, in some specimens this figure is almost completely black with the light bands within this spot reduced to two pairs of small or minute light spots; legs of general color. Face yellowish brown with black spot below compound eyes and at baso-lateral angles of clypeus; tips of mandibles black; fastigium verticis with two faint or distinct dark spots. Tegmen semi-transparent white, veins and veinlets brown; towards base little darker; hind wing semi-transparent white, veins and veinlets brown. Male. Eighth abdominal tergite only little prolonged. Ninth abdominal tergite globular with apical area bent down and with concave surface; ventro-apical margin little concavely excised in middle, on both sides of excision with a strong process with about triangular dorso-ventrally compressed base and down-curved, narrow, longconical apical area with acute tip. Tenth abdominal tergite in middle and between projections of ninth tergite with a pair of narrow, upright, acute projections curved faintly proximad, base of projections distant, oval, compressed. Epiproct long, oval, furrowed; paraproctes forming large plate at internal base of cercus ( Figs. 57C–D, F). Subgenital plate with convex lateral margins, apical margin on both sides oblique, in middle with bicornute median process; slightly curved styli inserted at oblique areas of apical margin. Phallus with a narrow elongate but little sinuate sclerite with forked and recurved base, in situ embedded into a membranous sac ( Fig. 58J). Female. Seventh abdominal sternite largely membranous with transverse riffles, sclerotised area restricted to a lateral convex swelling on both sides of a wide median furrow, posterior side of those swellings and area in between covered by long hairs. Subgenital plate separated by a long membranous area with transverse folds from preceding sternite; plate semi-oval, vaulted and with compressed lateral areas, apical margin rounded ( Fig. 59L). Ovipositor elongate substraight with faintly approaching margins, tip with narrowed margins, subobtuse ( Fig. 59O). Measurements ( 6 males, 6 females).—body w/wings: male 39–47, female 39–47; body w/o wings: male 26– 33, female 30–45; pronotum: male 5.2–6.5, female 5.5–6.5; tegmen: male 31–39, female 30–38; tegmen width: male 11.0, female 10.5–11.4; hind femur: male 14.0–16.5, female 15–18; antenna: male 80–125, female 120–130; ovipositor: female 25–30 mm.   Discussion.  D. panitvongiwas previously known only from the typelocality, Sakaerat, Nakhon Ratchasima Provinceof Thailandand with the subspecies D. p. boulaphaGorochov & Dawwrueng, 2015 from Boulapha district in Laos. The present findings show that its range obviously covers a rather large area from Northeastern Thailand( Phetchabunand Loeiprovinces) to South Cambodiaand even to Con Son Islandin South Vietnam. 2028147642 2015-05-09 2015-05-12 2015-05-09 RBINS Kirirom N.
