( Figure 13 View Figure 13 )
Material examined
Holotype (♀). Dak Lak, Chu Yang Sin NP, 800–940 m a.s.l., 2–10 June 2007, Malaise trap, C. v. Achterberg and R. de Vries leg. ( RMNH).
Diagnosis
Frons without carina between antennal sockets; face with small, fine punctures; clypeus without apical swelling, basal half slightly raised, transverse ridge at lateral corner present; ovipositor 2.3 × as long as hind tibia.
Description of holotype
Body length 13.2 mm, fore wing 12.0 mm, ovipositor 7.0 mm. Head. Antenna with more than 35 flagellomeres (apical part missing), first flagellomere 1.6 × length of second; diameter of lateral ocellus 0.9 × ocellar–ocular distance; frons impunctate, without carina between antennal sockets; inner margins of eyes strongly concave above antennal sockets, convergent ventrally; face 0.8 × as high as wide, slightly raised medially, with small, fine punctures, pubescent, upper margin broadly concave between antennal sockets; clypeus smooth, about 0.35 × as high as wide, flat with basal half slightly raised, apical margin thin, emarginate; malar space short, about 0.15 × basal width of mandible; occipital carina complete, meeting hypostomal carina about 0.55 × basal mandible width from base of mandible.
Mesosoma
Epomia about 0.33 × as long as mandible basal width; pronotum impunctate and polished laterally, punctate and pubescent dorsally; mesoscutum densely pubescent, about 1.25 × as long as width at anterior level of tegulae, notaulus indistinct; scutellum strongly convex, pubescent, lateral carina strong on basal half; mesopleuron with small punctures, pubescent, epicnemial carina strong on lower half of mesopleuron, sternaulus moderately impressed anteriorly; metapleuron polished, with fine punctures, pubescent dorsally, anterior lobe of submetapleural carina with carinae, posterior part of juxtacoxal carina present; propodeum polished, impunctate dorsally except lateral areas with sparse hairs, anterior transverse carina entirely absent, area superomedia open behind, 0.7 × as long as wide, pleural part of posterior transverse carina partly present, propodeal spiracle elongate, about 3.4 × as long as wide. Hind leg with femur 3.2 × as long as wide, length about 0.8 × tibia, basitarsus length 0.3 × tibia, 0.33 × tarsus, 1.9 × second tarsomere, fifth tarsomere longer than third. Fore wing vein Rs & M basad of cu-a, vein 2 rs-m about 0.5 × length of 3 rs-m, hind wing with distal part of vein M + Cu straight, first abscissa of vein Cu 1 0.4 × as long as vein cu-a.
Metasoma
Tergites with very small punctures, pubescent, first tergite 1.6 × as long as apical width, median longitudinal carina present basally, lateral carina weakly extending to spiracle; second tergite 0.65 × as long as apical width, 0.7 × as long as first tergite, 1.3 × longer than third tergite, basal and apical oblique grooves moderately deep; ovipositor straight, length of ovipositor from tip of hypopygium 2.3 × length of hind tibia, tip truncate, lower valve with seven weak teeth.
Colour
Antenna brown; frons and hind side of vertex marked with black; mesoscutum with three black stripes, median stripe joined posteriorly to black mark in front of scutellum; mesopleuron with black stripe at anterior margin, extending from above fore coxa to groove below subalar prominence and another black stripe at ventral half of mesopleural sulcus, plus a small round spot medially, under subalar prominence; propodeum with black patches in lateral areas; mid femur with black stripes on posterior face dorsally and on anterior face ventrally, hind leg with anterior face of coxa blackish, posterior face with round, black spot medially, trochantellus, basal and apical parts of tibia reddish, ventral reddish stripe of tibia long, connecting to reddish stripes at base and apex, upper part of posterior and anterior faces of tibia with reddish stripes medially, tibia and tarsus brown; wings brownish yellow; tergites with two lateral blackish brown to black spots.
Male. Unknown.
Comparison
This species resembles T. maskeliyae and T. zebra in general colour pattern. It can be distinguished from both by its finely punctate face, longer ovipositor and its frons without a carina between the antennal sockets.
Etymology
This species is named after the Latin for a long spear, referring to the long ovipositor, and is a noun in apposition.
Distribution
Currently known only from Chu Yang Sin NP, Dak Lak Province, Central Highlands of Vietnam ( Figure 5 View Figure 5 ).
Ecological notes
The single specimen was collected in evergreen forest at an elevation of 800–940 m a.s.l.
