Description. Male. Holotype. Head. Scape and pedicel black; postpedicel black except for yellow base; 2 black ocellar macrosetae; vertex black, sparsely brown tomentose; frons black; face black, apical half grey tomentose and basal half brown tomentose; mystax with black and yellow setae; palpus with long black and short yellow setae; proboscis black with 3 brown ventral macrosetae and 2 setae, remaining yellow; labial setae yellowish; occiput grey tomentose; black and yellow occipital setae; 4 black postocular macrosetae.

Thorax. Antepronotum and postpronotum black, brown tomentose dorsally and grey laterally; mesonotum black; lateral margin of mesonotum, postpronotal, sutural, prescutellar spot and scutellum brown tomentose; mesopleuron grey tomentose, except for the anterior half of black anepisternum.

Lengths. Body 21.1mm; wing 12.7mm.

Holotype conditions. Wing mounted in microslide with Canada balsam. Part of the abdomen and the terminalia in microtube with glycerine. Microtube and microslide pinned with specimen.
