Diagnosis: It belongs to the annulicornis species-group, and can be separated from other species within that group based on the combination of head, flagellomeres, mesosoma and metasoma mostly dark brown to black, body length and fore wing length 2.3–2.5 mm, and shape of T1 and T2.
Description: Male. Body length 2.0–2.1 mm. Fore wing length 2.2–2.3 mm. Head color: mostly dark brown to black, except for yellow clypeus, labrum, mandibles, and spot on lower corner of gena near oral foramen. Mesosoma color: entirely dark brown to black. Metasoma color (dorsally): mostly dark brown to black, except for yellow-orange anterior 0.4–0.6 of mediotergite 1. Coxae color: pale/pale/mostly or completely dark. Metatibia color: mostly pale, with posterior 0.1–0.2 dark. Metatarsus color: dark. Pterostigma color: pale, with thin dark margins.
Comments: Only the holotype male was used to morphologically characterize the species. The known female specimen are in poor condition and entirely bleached, with a coloration that most likely does not represent the actual females of this species (Fernandez-Triana et al. 2014).
