Belonogaster atrata von Schulthess, 1912

(Figs 1B–F)

Belonogaster atratus von Schulthess, 1912: 41, ♀ – “Westafrika, Uelleburg” (lectotype female ETHZ).

Material examined. DEMOCRATIC REPUBLIC OF CONGO: Tshopo, Yangambi, MAB forest, 0.861N 24.400E, 417 m, 27.VI.2023, leg. A. Dorchin, 1♀ (MSVI).

Distribution. Equatorial Guinea, Democratic Republic of Congo * (Fig. 1A).

Notes. Richards (1982) reported Cameroon as origin of the lectotype, but the type locality “Uelleburg” is in fact in Equatorial Guinea, close to the current city of Mbini (Pont 2013: 160).

The examined female (Figs 1B–F) presents some differences from the description provided by Richards (1982): sides of mesoscutum and pronotum with smaller punctures and interspaces densely micropunctate-reticulate, mesoscutum with short black setae and inconspicuous pale pubescence, pubescence of metasoma grayish, scutellum and metanotum red. These differences are here considered to be intraspecific variability, since the specimen coincides with the description in all other diagnostic characters, in particular the sculpture of the propodeum, the rest of the pattern, the vestiture of the femora and the brevity of the T1 and of the petiole of the T2.
