Identification

This species can be separated from the rest of the group as it presents a quite dense white pubescence directed backwards at the meso and especially at the metapleurae. The other species may present some isolated small setae, but never becoming pubescent in appearance. It also presents the most developed propodeal process of the four species in this complex.

Its general shape, size and colour might resemble Aenictus rotundatus, but can be separated due to its shorter scapes (SIL >60 for rotundatus) and cited pubescence.

    • Type-material: syntype workers (number not stated).
    • Type-locality: South Africa: Orange Free State, Reddersburg (H. Brauns).
    • Type-depository: NHMW.
    • Status as species: Emery, 1904a: 111; Emery, 1910b: 31; Santschi, 1914b: 69; Arnold, 1915: 139; Wheeler, W.M. 1922a: 754; Bolton, 1995b: 60; Hita Garcia, et al. 2013: 201.

Type Material

  • Syntypes, SOUTH AFRICA: Orange [CASENT0911440] (4w) NHMB [Examined by Gomez, 2022]; Syntype, SOUTH AFRICA: Free State, Reddesburg (1w) [CASENT0919642] NMHW: Coll. Mayr [Examined by Gomez, 2022]; Syntypes, SOUTH AFRICA: Free State, Orange (Arnold) (6w) MHNG: Coll. Forel [Examined by Gomez, 2022].

Gomez (2022): There is a series of 8 workers at MNHW from Reddesburg, identified by E. Mayr as types for “A. rotundatus laevigatus”, probably part of the type series for A. steindachneri, but not labelled as such.
