Description
Female (Fig. 1 View Figure 1 ). Length, mesosoma plus metasoma, 0.57 mm. Head (Fig. 1 View Figure 1 A) dark brown with scrobes pale; eyes dark red, ocelli red. Mesosoma (Fig. 1 View Figure 1 B) with mid-lobe of mesoscutum dark brown, except sides and posterior margin light brown, axilla and propodeum dark brown, side lobe of mesoscutum brown-yellow with a dark patch anteromedially, scutellum pale yellow with posterior margin infuscate, metanotum pale brown-yellow. Metasoma (Fig. 1 View Figure 1 C) dark brown, except middle of T5-T6 and 3/4 apex of T7. Ovipositor yellow with third valvula brown. Antennae (Fig. 1 View Figure 1 D) yellow-brown with radicle and scape brown. Wings (Fig. 1 View Figure 1 E) hyaline, venation pale brown and tegula dark brown. Legs (Fig. 1 View Figure 1 F) pale yellow, except base of hind coxae brown.
Head (Fig. 1 View Figure 1 A) as wide as mesosoma. Maxillary and labial palps 1-segmented. Mandibles with three teeth. Eyes with fine and transpar-ent setae. Stemmaticum with transverse reticulate sculpture. Frontovertex with robust setae. Antennal formula 1,1,4,2 (Fig. 1 View Figure 1 D); F1 2 × as long as wide, 1.5 × as long as pedicel, as long as F2 and slightly shorter than F3, respectively. F2 and F3 1.83 × and 2.5 × as long as wide, respectively. Flagellum with the following numbers of longitudinal sensilla: F1:2, F2:2, F3:3, F4:4, F5:3, F6:3.
Mid-lobe of mesoscutum (Fig. 1 View Figure 1 B) with six setae, each side lobe with two setae. Axilla with one robust seta anteriorly. Mid-lobe of mesoscutum, axillae and scutellum with reticulate sculpture. Distance between placoid sensilla on scutellum 4.4 × the maximum width of a sensillum. Distance between anterior pair of scutellar setae 1.31 × as long as the distance between posterior pair. Fore wing (Fig. 1 View Figure 1 E) 2.74 × as long as wide, with a clear asetose area around the stigmal vein and a wide asetose strip along posterior margin of wing disc; marginal fringe 0.37 × as long as disc width, costal cell with nine setae in a row, basal cell with two setae, submarginal vein with two setae, marginal vein with five setae along anterior margin. Tarsal formula 5-5-5 (Fig. 1 View Figure 1 F). Mid-tibial spur 0.66 × as long as correspond-ing basitarsus, the latter 0.35 × as long as mid-tibia. Hind tibia 0.96 × as long as mid-tibia.
Petiole smooth (Fig. 1 View Figure 1 C). T1-T5 laterally with scale like reticulation. T2- T7 with 2+2, 2+3, 1+1, 2+2, 1+2+1 and 4 setae, respectively. T7 1.29 × as wide as long. Ovipositor exerted, apparently originating from level of T4, 1.19 × as long as mid-tibia, 0.91 × as long as mid-tibia and basitarsus combined. Third valvula 0.58 × as long as second valvifer, 0.38 × as long as ovipositor.
Diagnosis
Head and body largely dark brown, except scutellum and some pale spots on last three metasomal segments. Antennal F1 and F2 with longitudinal sensilla, F1 1.5 × as long as pedicel. Mid-lobe of mesoscutum with three pairs of setae. Third valvulae brown and terminating in an abrupt angle.
Etymology
The specific name is derived from the collection locality name.
Taxon discussion
The new species is easy to distinguish from other species of this group by the combination of a dark metasoma, F1 with longitudinal sensilla and distinctly longer than pedicel and three pairs of setae on mid-lobe of mesoscutum.
