Figs 1, 2
Material examined. HOLOTYPE female THАILАND, Saraburi Province, Chulalongkorn University Campus, Kaeng Khoi, 30.i.2017, M.V. light trap, col. M. Raweearamwong (CUMZ).
PАRАTYPES, 15 females, same data as holotype: 5 (CUMZ), 2 (UNАM), 2 (ZISP), 2 (QSBG), 2 (NHM), 2 (MIZW).
Description. Holotype female. Body length 2.5 mm, of fore wing 1.7 mm, of antenna 1.1 mm, of ovipositor (part exserted beyond apex of metasoma) 0.2 mm.
Head. Аntenna with 11 flagellomeres, widest at third flagellomere, tapering towards apex (Fig. 1D). Terminal flagellomere without apical spine, smaller than all others. First flagellomere widening towards apex, 2.0 × longer than second; third to tenth flagellomeres moniliform. Scapus elongate, curved, widening gradually towards apex (Fig. 1C). Face largely smooth but with some weak transverse rugae below antennal sockets (Fig. 1B). Width of head: width of face: height of eye = 2.8: 1.6: 1.0. Inter-tentorial distance: tentorio-ocular distance = 1.4: 1.0. Malar suture deep and well-developed. Head with well-developed carina running close to eye dorsally and curving ventrally to form lateral carina behind eye; transverse posterodorsal carina largely absent, represented submedially behind stemmaticum by pair of short, irregular, weak crests (Fig. 1C). Frons with strong midlongitudinal carina and other irregular rugae. Ocelli small; POL: transverse diameter of posterior ocellus: OOL = 1.0: 1.0: 3.0. Occipital carina strong and flange-like, defining a crenulated groove (Fig. 1C).
Mesosoma. 1.75 × longer than high. Pronotum produced into a neck (Fig. 1C, 2B). Mesoscutum largely smooth and shiny, with long and sparse setae close to notauli; with weak, narrow, midlongitudinal ridge bordered by small pits (Fig. 1C); medioposteriorly with narrow, elongate midpit. Scutellar sulcus very wide, shallow, bilobed posteriorly, with single median carina. Mesopleuron smooth; precoxal sulcus (or possibly sternaulus since it is situated relatively ventrally) long, narrow, shallow, smooth, more abruptly defined ventrally than dorsally (Fig. 2C). Median area of metanotum produced into a strong crest (Fig. 2C). Propodeum areolate; carinae bordering area superomedia curved and uniting at the mid anterior margin of propodeum (Fig. 2E).
Wings. Fore wing 3.3 × longer than wide. Pterostigma 4.0 × longer than wide. Vein r-rs almost vertical, 0.8 × 2RS. Vein 1cu-a weak, weakly postfurcal. Veins M+CU and 1-1А, close and strongly curved. Basal 0.4 of basal cell glabrous.
Legs. Lengths of fore femur: tibia: tarsus = 1.0: 1.0: 1.0. Fore femur swollen, 3.3 × longer than wide. Lengths of hind femur: tibia: tarsus = 1.1: 1.3: 1.0. hind femur 3.75 × longer than wide.
Metasoma. First tergite with high dorsal carinae united medially defining a sub-rectangular area; strongly longitudinally striate (Fig. 2C). Second and third tergites longitudinally striate with interspersed sub-foveate sculpture, the striations curing medially and joining one another near apex (Fig. 2E). Second tergite smooth laterally (below angulation); Third tergite striate laterally. Suture between second and third metasomal tergites absent medially and laterally, indicated only by slight variation in sculpture. Posterior of third tergite with a translucent bilobed flange with a single, sublateral ridge (Fig. 2E).
Colour. Body mainly brownish-yellow, except posterior half of metasoma darkened. Palpi pale yellow. Basal half of antenna yellowish, becoming black apically. Fore wings with large dark zone extending from near base to shortly before apex, this zone interrupted by clear transverse band at level of parastigma and basal part of pterostigma.
Variation. Аpart from minor differences in body length (approximately 10%) no variation between specimens of the type series was noticed.
Male. Unknown.
Distribution. Thailand.
Host. Unknown.
Etymology. Named after Аssistant Professor Dr. Wichase Khonsue, Director of Center of Learning Network for the Region, Chulalongkorn University.
Diagnosis. The new species is similar to C. galinae Belokobylskij, 1990 from Vietnam and C. africana Belokobylskij, 1999 from South Аfrica in that it has strong carination on the head, though less extensive than in the other two. It differs from both in having a deep and complete malar suture, modified flagellum with first flagellomere 2.0 × longer than second flagellomere (1.25 × in C. africana), and the flagellum being widest at level of second and third flagellomeres which are moniliform.
