Paramblynotus nigricornis Benoit, 1956

FEMALE: Length 3 mm. Head and mesosoma black; antenna, legs, and metasoma brown. Wings clear.

Antenna 13-segmented with apical flagellomere less than twice the length of the subapical flagellomere. Ocellar plate distinctly raised. Vertex foveate-reticulate. Antennal scrobes longitudinally carinate above and glabrous below. Gena coarsely sculptured, rugose to rugulose. Clypeus diagonally carinate. Pronotal crest medially not raised into a triangular process. Upper mesopleuron foveate. Scutellar sulcus divided by a several longitudinal carinae. Metepisternum alveolate to rugose with dense pubescence in lower part, without elevated glabrous area. T6 of female metasoma the largest among all terga, lateral margin of T7 concave, T8 distinctly exposed. 1mt/2–5mt 5 0.65.

MALE: Unknown.

Paramblynotus nigricornis forms a distinct, monophyletic clade with P. samiatus , P. claripennis , P. maculipennis , and P. townesorum within the trisetosus group. They are easily separated from the rest of the species group by (1) ocellar plate distinctly raised; (2) T6 of female metasoma the largest, lateral margin of T7 concave, T8 distinctly exposed; (3) gena coarsely sculptured, rugose to rugulose; and (4) metepisternum without elevated nude area. Among the five species, P. nigricornis and P. claripennis are separated from the rest by having clear wings. In addition, P. nigricornis is unique among the five species in that it has 13-segmented antenna with apical flagellomere less than twice the length of the subapical one.

MATERIAL EXAMINED: MRAC: 1♀ (holotype, one antenna and wings from one side are mounted on separate slide).

DISTRIBUTION: Zaire: Kivu.
