Type material.

Holotype ♀, Thailand, Nakhon Ratchasima province, Khoa Yai National Park , 19. iv. 2007, 14 ° 25.535 ' N, 101 ° 23.442 ' E, Malaise trap, col. S. Warat ( QSBG).

Diagnosis.

Troporhogas hugoolseni sp. nov. can be differentiated from others with similar colour pattern (orangish mesosoma, T 1 with black mark anteriorly, T 2 largely and T 6 entirely white) by having the vertex smooth except for small setiferous punctures and the raised oblique area of mesopleuron immediately below subalar depression moderately densely punctate but without oblique striation.

Description.

Holotype, female body length 6.2 mm; fore wing 5.5 mm; ovipositor sheath 0.5 mm.

Head. Antenna incomplete, with at least 40 flagellomeres. First flagellomere 2.0 × longer than second and third, respectively. Width of head: width of face: height of eye = 3.1: 1.6: 1.0. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 1.4: 1.6. Face and clypeus rugose with sparse setosity laterally. Vertex and temple shiny and with sparse setosity. Occipital carina complete, curved dorsally.

Mesosoma. Mesosoma 1.6 × longer than high. Mesoscutum shiny, sparsely punctate, with narrow foveate longitudinal groove mid-posteriorly. Scutellar sulcus with three carinae between outer pair. Axillae striate. Raised anterodorsal area of mesopleuron below subalar depression with diagonal striation. Precoxal sulcus short, broad, and shallow, with weak irregular striation. Mid-longitudinal carina of metanotum strong and roundly protruding posteriorly, weak anteriorly. Propodeum reticulate with long setae, with submedial carinae meeting medially in V-shape connected by ladder of variably developed transverse crenulations, lateral to these with moderately dense, small setiferous punctures.

Wings. Fore wing. Lengths of fore wing veins r-rs: 3 RSa: 3 RSb = 1.0: 2.8: 4.7. Lengths of vein 2 RS: 3 RSa: rs-m = 1.1: 1.9: 1.0.

Legs. Lengths of fore femur: fore tibia: fore tarsus = 1.0: 1.1: 1.5. Lengths of hind femur: hind tibia: hind tarsus = 1.0: 1.3: 1.6 Length of hind femur and tibia 5.0 × and 8.3 × as long as wide, respectively. Hind tibial spurs glabrous. Tarsal claws with large acutely pointed basal lobe.

Metasoma. T 1 1.1 × longer than posteriorly wide. T 2 1.5 × as long as T 3. TT 1 and 2 with mid-longitudinal carina dorsally, sparsely striate. TT 3-6 with distinct striate sculpture and without medial longitudinal carina. Ovipositor sheath straight and shorter than hind basitarsus, ~ 0.3 × length hind femur (including trochantellus).

Colour. Body tricoloured; scapus, pedicellus and flagellar segments dark brown. Head including stemmaticum orange-red, mouthparts paler brownish yellow. Mesosoma and tegulae ochraceous. Metasoma bicoloured; TT 1, 2, and 6 white but T 1 and T 6 with small black marks anteriorly and posteriorly, TT 3–5 black with small white anterolateral areas and with small white spot on the mid-posterior margin of T 5, hypopygium white. Wings hyaline with dark brown venation, pterostigma brown. Fore legs and mid legs yellow, hind legs mainly dark brown. Ovipositor and ovipositor sheath black.
