Type material:
Anochetus africanus madagascarensis Forel, 1887: 382 [23]. Lectotype: worker, Madagascar, Tamatave Province, Ivondro, (Dr. Conrad Keller) (MHNG) present designation [examined] AntWeb CASENT0101574. Raised to species by Brown, 1978: 557 [2].
Anochetus africanus friederichsi Forel 1918: 155 [24]. Lectotype: worker, Madagascar, Tamatave Province, Prune Island (Nosy Alanana) (Friederichs) (MHNG), present designation [examined] AntWeb CASENT010165. Synonymized with madagascarensis by Brown, 1978: 557 [2].
Worker measurements: maximum and minimum based on n = 20. HL 1.35-1.68, HW 1.19-1.53, CI 87-94, EL 0.23-0.28, ML 0.73-0.93, MI 53-57, SL 1.11-1.41, SI 89-95, WL 1.60- 2.02, FL 1.13-1.54, PW 0.63-0.80.
Queen measurements: maximum and minimum based on n = 5. HL 1.52-1.66, HW 1.48-1.55, CI 92-97, EL 0.32-0.36, ML 0.81-0.89, MI 53-55, SL 1.26-1.39, SI 85-91, WL 1.99- 2.22. FL 1.35-1.49, PW 0.84-0.92.
Male measurements: maximum and minimum based on n = 5 from Madagascar: HL 0.85-1.89, HW 1.07-1.20, CI 122- 135, EL 0.63-0.69, SL 0.20-0.22, SI 18-21, WL 1.90-1.98, FL 1.35-1.47
Worker Diagnosis: Inner blade of mandible without teeth and denticles; apical end of inner blade with notched semicircular concavity (Fig. 1a). Eyes large (0.24-0.26 mm), projecting dorsally. In full face view, antennal scape extends beyond posterior margin of occipital lobe. Dorsal surface of head asetose. Pilosity and sculpture as in Figures 4a,b.
Queens alate: Very similar to worker and only slightly larger (Figs 4c,d). Queens of only one size. Ergatoid queens not recorded.
Males: Males light yellowish brown in color and with large projecting ocelli on vertex (Figs 4e,f). Males have been collected in Malaise traps in every month of the year and males have been noted to swarm and fly at dusk and early evening.
The species is most similar to A. grandidieri but can be easily distinguished by its large eyes (0.24-0.26 mm), and scapes that surpass occipital lobes.
Distribution and biology. A. madagascarensis is widespread throughout Madagascar in forest or shrubland habitats below 1100 m elevation and is also known from the Comoros. Forel's (1912:159) record of a male ' Anochetus sp.? africanus var. madagascariensis Forel " from Seychelles, Mahe, has not been seen and confirmed. This record most likely refers to pattersoni.In Madagascar, madagascarensis is widespread and has been collected in gallery, dry, littoral, lowland, and montane forests, and in desert spiny bush thicket in the southwest of Madagascar. The longer scapes and larger eyes of A. madagascarensis compared to A. grandidieri, correlate with nesting and foraging above the soil layer. The species was most often recorded nesting in rotten logs (99 collection records) followed by sifted litter (41). In addition, it was collected from dead twigs above ground (1), rot pockets (2), ground foragers (20), ground nests (6), Malaise trap (14), on low vegetation (2), and pitfall traps (4).
CO1. Shallow iIntraspecific and deep interspecific divergences between A. madagascarensis and the other species. Average within species sequence divergence of 1.67% (SE = 0.055) (Fig. 16).
Diagnostic barcoding loci. A. madagascarensis: A-21, T-423 (shared with one A. goodmani population), T-132 (shared with one A. grandidieri population), T-83, A-84, T-93, T, 138, C-306, T-513, A-595
