HOLOTYPE female THAILAND , Kanchanaburi province , Thongpapoom 13.vi.2009 , Aerial net , col. B. Butcher , DNA voucher CCDB-24264-C10 ( CUMZ ). Description. Holotype female. Length of body 5.5 mm , fore wing 4.5 mm , length of antenna 4.5 mm , length of ovipositor sheath 1.5 mm . Head . Antenna with 42 flagellomeres. Terminal flagellomere acuminate. Median flagellomere 1.2 × longer than wide. Malar space long, height of eye 1.5 × vertical distance separating lower margin of eye from mandible. Face finely punctuate rugulose superimposed on coriaceous sculpture, moderately short setose, eyes glabrous. Frons with a Y sculpture running from anterior ocellus. Height of eye: width of face: width of head = 1.0: 1.4: 2.4. Length of face (from dorsal margin of clypeus to anterior margin of antennal socket) 1.5 × width of face. Horizontal length of eye (measured perpendicular to face) 1.85 × horizontal length of head behind eye. Post-ocellar length: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 1.0: 3.3. Occipital and vertex rugulose superimposed on coriaceous sculpture. Mesosoma. Mesosoma 1.54 × longer than high, largely coarsely rugose and setose.. Notauli present but shallow, precoxal sulcus complete. Mesoscutum with weak longitudinal carina, mesopleuron and mesosternum with strongly striate. Median area of metanotum with strong dorsally protruding mid-longitudinal carina. Propodeum shiny with coriaceous sculpture by pair of anterior diverging carinae; groove deeper anteriorly with transverse carina; posterior laterally of propodeum with weak sculpture. Wings . Length of fore wing veins SR1: 3-SR: r = 4.0: 2.5: 1.0. Lengths of 2-SR: 3-SR: r-m = 1.5: 2.5: 1.0. Length of fore wing vein m-cu: 2-RS+M = 1.0: 1.0. Apex of hind wing vein C+SC+R with 1 thick setae. Legs. Length of fore femur: tibia: tarsus = 1.0: 1.1: 1.33. Length of hind femur: tibia: tarsus = 1.0: 1.25: 1.3. Hind basitarsus 2.0 × longer than sub-posteriorly deep. Metasoma. Carapace coarsely rugose; widest at 0.7 × distance from base to apex. Anterior sculpture radially areolate rugose. Posterior spines robust, ratio of distance of each spine tip 1.1 × spine length. Ovipositor exserted beyond apex of metasomal spines by approximately 1.5 × length of spine. Coloration. Body brownish; antenna, compound eyes, claws, tip of mandibles and ovipositor sheaths, black; mesoscutum, vertex, pterostigma and ovipositor, dark brown; Veins C+SC+R and M+CU1 of fore wing, half basal membrane of fore wing, veins C+SC+R and M+CU of hind wing, half basal membrane of hind wing, yellow brown; and apex of fore wing and hind wing, dark brown. Distribution. Kanchanaburi province , Thailand . FIGURE 1 . Light micrographs of Physaraia nanensis n. sp. , holotype female (♀).
