Description

Female. Body length 4.7 mm. Forewing 2.8 mm. Colour: wings bi-banded; pronotum and mesonotum orange; metasoma dark castaneous; head and metapectal-propodeal complex dark castaneous nearly black. Head: head longer than wide. Malar space longer than VOL, convergent anteriorly. Median clypeal lobe rounded. Antenna short; pedicel caliciform; flagellomere I as long as pedicel; flagellomeres short. Eye small [0.5 × LH], circular. Frons strongly foveolate. Ocelli small, DAO 1.0 × POL. Mesosoma: dorsal pronotal area foveolate, with anterior corner angled, lateral margin straight, and posterior margin sinuous; longitudinal pronotal sulcus complete. Anteromesoscutum weakly foveolate, longer than mesoscutellum; longitudinal antero-mesoscutal sulcus incomplete. Mesoscutellum short, foveolate, with longitudinal sulcus. Metapectal-propodeal complex 0.5 × as long as wide; metapostnotum with a longitudinal ridge between metaposnotal median carina and metaposnotal-propodeal suture; posterior spine of metapectalpropodeal complex short, thin. Metasoma: tergum II with dorsal surface polished, ventral surface polished. Genitalia: 2vf with anterior area narrow, posterior projection narrow, dorsal projection short; asf transversally oriented. Shaft (1vv+2vv) as long as sting body (2vf+3vv), valvulae equally wide. 3vv longer than wide.

Male. Body length 2.8 mm. Colour: wings bi-banded; metasoma dark castaneous; head and mesosoma dark castaneous nearly black. Head: head as long as wide. Malar space convergent anteriorly. Median clypeal lobe rounded. Antenna long; pedicel caliciform; flagellomere I as long as pedicel; flagellomeres long. Eye small [0.5 × LH], circular. Frons strongly foveolate. Mesosoma: dorsal pronotal area foveolate, with anterior corner angled, lateral margin straight, and posterior margin straight; longitudinal pronotal sulcus complete. Anteromesoscutum coriaceous, longer than mesoscutellum; longitudinal anteromesoscutal sulcus absent. Mesoscutellum short, foveolate, without longitudinal sulcus. Metapectal-propodeal complex more than 0.5 × longer than wide; metapostnotum without longitudinal ridge between metaposnotal median carina and metaposnotalpropodeal suture; posterior spine of metapectal-propodeal complex short, thin. Metasoma: tergum II with dorsal surface polished, ventral surface polished. Hypopygium with anterior spiculum long and wide. Genitalia: paramere ventral arm of short, wide, and club-shaped; dorsal arm shorter than ventral, filamentary.
