Description.
Male
(
Fig. 2
). Fully winged; length 1.5 mm. Forewing as long as mesosoma + metasoma (50: 50). Length of mesosoma + metasoma: 1.2 mm. Colour black, except antenna and legs brown. Antenna ¿liform, less than three times as long as head (32: 12). Antennal hairs long, slightly shorter than breadth of antennal segments.Antennal segments in following proportions: 5: 2: 3: 3: 3: 3: 3: 3: 3: 4. Head dull, apparently smooth, not rugose, less than twice as long as eye (12: 8). Clypeus very long, ovoid. Mandible very long, with teeth not distinct. Eye apparently bare. Occipital carina complete. Posterior ocelli touching occipital carina. Temple distinct, very short. POL = 1.5; OL = 0.5; OOL = 2; TL = 1; greatest breadth of posterior ocelli about as long as POL; frontal line not visible. Propleuron short, forming a neck between head and pronotum, deeply inserted in occiput. Pronotum short, much shorter than head (2: 12) and scutum (2: 7); pronotal tubercle reaching tegula. Scutum apparently bare, apparently unsculptured. Notauli incomplete, reaching about 0.7 length of scutum. Scutellum apparently unsculptured, shorter than scutum (4: 7). Metanotum shorter than scutellum (2: 4), apparently unsculptured. Propodeum longer than scutum (8: 7), with dorsal surface reticulate rugose, with very large areolae; posterior surface not completely visible. Forewing hyaline, without dark transverse bands, with two basal cells (costal and median + submedian) clearly enclosed by pigmented veins; median and submedian cells fused (M+Cu vein, usually separating median and submedian cells, only shortly present near M vein (
Fig. 2C
)). Pterostigma narrow, much longer than broad (10: 2); marginal cell open; stigmal vein regularly curved, without distinct proximal and distal parts, almost reaching wing’s border, similar to that of
Aphelopus
Dalman, 1823
species.
Petiole little distinct, much shorter than propodeum (1: 27). Foreleg segments in following proportions: 5 (coxa): 3 (trochanter): 10 (femur): 6 (tibia): 15 (tarsus). Midleg segments in following proportions: 6 (coxa): 2 (trochanter): 8 (femur): 8 (tibia): 14 (tarsus). Hindleg segments in following proportions: 5 (coxa): 3 (trochanter): 12 (femur): 14 (tibia): 17 (tarsus). Maxillary and labial palpi only partly visible; palpal formula apparently 6/3. Tibial spurs 1/1/2.
