Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Material of the unavailable names biroi, haltrichi, rufitarsis, szaboi referred to hungaricum by Csösz & Markó, 2004: 52.

Wagner et al. (2017) - Smallest species of complex, CS = 657 ± 34 [584, 722] μm. Dark brown to blackish.

Head moderately elongate, CL / CW = 1.020 ± 0.014 [0.996, 1.051]. Eye large, EYE / CS = 0.184 ± 0.007 [0.170, 0.194]. Scape short, SLd / CS = 0.747 ± 0.015 [0.716, 0.773]. Mesosoma shortest within complex and narrow, ML CS = 1.103 ± 0.018 [1.064, 1.146], MW / CS = 0.628 ± 0.008 [0.608, 0.645].

Promesonotal dorsum convex, metanotal groove shallow. – Smoothest and shiniest surface within complex: longitudinal costae and costulae on head dorsum and occiput usually interrupted by large-scale smooth and shiny areas. Postoculo-temporal area of head with few longitudinal costae and costulae, POTCos = 2.14 ± 1.21 [0.13, 4.50]. Longitudinal costae and costulae on mesosoma interrupted by smooth and shiny areas, lateral side of propodeum with strongly pronounced smooth and shiny area, Ppss = 85.6 ± 36.1 [21.1, 169.5] μm. Dorsum of petiolar node usually smooth, exceptionally feebly microreticulated. – Connected stickman-like or reticulate microsculpture: small units scattered over 1st gastral tergite, MC1TG = 14.91 ± 2.53 [9.64, 20.85]. – Some workers with long c-shaped, crinkly, or sinuous hairs on ventral head posterior to buccal cavity.


Paramere structure belongs to caespitum-like form: ventral paramere lobe with one or two sharp corners; without distinct emargination between paramere lobes in posterior view, both paramere lobes reduced in size; in ventro-posterior view, second corner on ventral paramere lobe missing or < 87 μm apart from first. In posterior view, typically only one sharp corner on ventral lobe.

Type Material
