Redescription. Male. Fully winged; usual length 2.2–4.3 mm (in specimen from Canary Islands length 1.3 mm). Head black or brown, except clypeus and mandible testaceous; antenna testaceous or testaceous-brown; mesosoma testaceous-brown (in two small paratypes from Mt. Tachibanyama), or with prothorax and scutum brown, scutellum and metanotum testaceous-brown, propodeum black (in holotype and large paratype from Omogo Valley); metasoma brown or testaceous; legs testaceous. Antennae filiform, not geniculated, not thickened distally, without rhinaria, articulated to prominent contiguous processes; antennal toruli very far from upper margin of clypeus; antennal segments in following proportions: 10:3:32:31:30:28:26:25:23:24. Head shiny, smooth, very finely punctate, unsculptured among punctures, covered with fine short hairs; dorsal side of head swollen; occipital carina complete; ocelli distinct; POL = 3; OL = 2,5; OOL = 7; OPL = 8; TL = 13; face with track of median furrow, only present in front of anterior ocellus and near antennal toruli; eye large, much shorter than head (13:29); region of face from clypeus to antennal toruli with two complete longitudinal and median sutures much nearer antennal sockets than clypeus. Maxillary palpi with six segments; labial palpi with two-three segments. Pronotum very short, partly hidden behind occiput, with complete median longitudinal furrow; pronotal tubercle reaching tegula. Scutum and scutellum shiny, smooth, finely punctate, unsculptured among punctures, covered with fine short hairs. Notauli incomplete, reaching approximately 0.2 × length of scutum. Metanotum very short, medially rugose. Propodeum rugose, dull, without longitudinal or transverse keels. Meso- and metapleuron shiny, smooth, unsculptured or finely punctuate. Fore wing hyaline or weakly darkened, without dark transverse bands, with four cells fully enclosed by pigmented veins (CC, BC, SBC, 1DC); marginal cell open.
