Species in this genus are characterized by having 8 flagellomeres, relatively reduced eyes (usually females), wings frequently large and floppy with reduced venation (C, Sc, M+CU, 1CUa, 1CUb and 2CU only present), fore wing with only one cell enclosed by tubular veins (costal), and hind tarsomeres 1-3 elongated posteriorly into spines. According to
The goal of this paper is to disseminate the pictorial key for females of

Female body length: 1.6 mm (head to propodeum). Head color: black. Mesosoma color: black. Legs color: fore leg: trochanter, trochantellus, tibia, tarsus light-castaneous; femur dark-castaneous. Wings: fore and hind wing hyaline. Metasoma: petiole light-castaneous; tergites: dark-castaneous.
Eye: 1.8–2.0 times higher than wide. Postorbital carina: present and complete; conspicuously outlined; detached from the margin of lower eye orbit; sinuous (see malar space); reaching the top of eye orbit (some foveae may also be present and are part of carina). Antennal foramen: inserted at the same level as the top of eye orbit; antennal rim: conspicuously elevated laterally (head lateral view). Median lobe of mesoscutum: slightly curved or flat (lateral view). Notaulus: present as continuous furrow. Metanotum: not concealed by mesoscutellum (dorsal view). Sculpture of hind femur: unsculptured (nitid, autapomorphy for
