Figs 4–7 , 10, 11

Etymology: From Latin lanternarius (carrying a lantern).

Description:

Female.

Body length 3.3 mm.

Head roundly narrowed behind eyes in dorsal view; temple short, 0.63 times as long as eye width. Flagellum of antenna with 14 segments; all flagellomeres, except apical one, distinctly elongate, mostly 1.4–1.6 times as long as wide ( Fig. 4 ). Upper tooth of mandible longer than lower tooth. Malar space about as long as basal width of mandible. Face and frons granulate. Vertex very finely granulate, matt.

Mesonotum granulate, usually impunctate (indistinctly punctate in one paratype). Notaulus substituted by a short distinct carina. Mesopleuron granulate, usually indistinctly punctate centrally. Sternaulus in anterior part of mesopleuron weakly impressed, more coarsely granulate than the remaining mesopleuron, sometimes also with very shallow wrinkles. Propodeum evenly granulate, impunctate; basal keel 0.4 times as long as apical area; spiracle separated from pleural carina by about 1.5 diameters of spiracle; apical area more or less rounded anteriorly, with a pair of longitudinal carinae reaching transverse carina ( Fig. 11 ).

Fore wing length 2.26 mm. First section of radial vein about as long as width of pterostigma. Metacarp not reaching apex of fore wing. Second recurrent vein interstitial ( Fig. 10 ). Vein 2 rs–m moderately long ( Fig. 10 ).

First tergite length 0.66 mm; tergite slender, almost entirely smooth, with petiole slightly striate laterally, with small deep glymma ( Fig. 7 ). Second tergite length 0.28 mm. Thyridia very shallow (sometimes hardly discernible), about 2.5 times as long as wide. Ovipositor long; sheath 2.0 mm, 3.0 times as long as first tergite ( Fig. 6 ).

Body brown to black with brownish hue. Palpi, mandibles (except teeth), clypeus, scape and pedicel of antenna, tegula and legs yellow to yellowish brown. Flagellum usually yellowish basally, evenly darkening towards apex. Pronotum reddish.Pterostigma brown, sometimes with pallid basal, apical and peripheral spots. Metasoma behind first segment usually brown to dark brown, with second tergite yellowish dorsally; sometimes tergites yellowish ventrally.

Male. Unknown.
