The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.

  • mentu. Aenictus mentu Weber, 1942a: 40, fig. 2 (w.) SOUTH SUDAN.
    • Type-material: syntype workers (number not stated, “one colony”).
    • Type-locality: South Sudan (“Anglo-Egyptian Sudan”): Imatong Mts, 4.viii.1939, 4200 ft. No. 1436 (N.A. Weber).
    • Type-depository: MCZC.
    • Status as species: Weber, 1943c: 292; Bolton, 1995b: 60.
    • Distribution: South Sudan.

Type Material

  • Syntype, SOUTH SUDAN: Equatoria Region, Imatong Mountains (Neal A. Weber) 24 Jul- 5 Aug. 1939. (1w) [MCZC:ENT:26131] MCZC [Material seen on web by Gomez, 2022].

Taxonomic Notes

Gomez (2022): The type material is located at the MCZC, but it wasn’t available for examination for this study. Also, no other specimens were found in any of the major museum collections that provided access or material loans. I have provisionally placed this species in the same group as Aenictus rixator due to measurements from the type images (HW~0.40, CI~90), habitus, clypeal shape and mandibles. Based on paucity of material and the limited image quality, presently I have to refrain from offering a more accurate diagnosis or description until the types can be analyzed in detail.
