Known from type material collected from the Anatolian Plains of Turkey, nothing is known about the biology of Rossomyrmex anatolicus.

Identification

Although it is very similar to Rossomyrmex proformicarum because of the abundant pilosity, it can be distinguished by the petiole, which gradually narrows towards the apex. This character, together with the high number of hairs, can be used to differentiate it from Rossomyrmex minuchae.

Description

Worker

Head length: 1.19-1.41 mm; Head width: 1.05-1.22 mm; Occipital width: 0.84-1.00 mm; Scape length: 0.84-0.93 mm; Thorax length: 1.41-1.62 mm. General colour is black or dark brown. The tegument is bright with some ridges in the mesopleuron and metapleuron. There are two types of whitish hairs: very small (about 50 μm) adpressed hairs, and long hairs (about 200 μm) which are abundant on the thorax, petiole and gaster and less abundant on the head.

Long head with sides slightly bowed and with occipital region slightly excised. Slightly marked keel in the front region, the edge of the clypeus is convex and complete, with a small lump on its upper part. Well-developed reddish mandibles with eight teeth, the apical and pre-apical sharper and more developed than the others. Drumstick-like scapes, funiculus with eleven articles, the first being four times longer than its average width and as long as the second and third.

The tegument of the thorax is bright and polished, striated in the pleuron of mesothorax and metathorax only. The entire surface is covered with adpressed hairs and long hairs (around 200 μm), with thirty appearing on the pronotum, a dozen on the mesonotum and epinotum.

High petiole scale narrowing to the apex, where a dozen long hairs appear as well as on both side margins. Oval gaster with numerous hairs all over the dorsal and ventral surfaces.

Type Material

Holotype and type series (19 workers) come from Belembasy Bebi’s harbour (Konya, Turkey), collected the 7 June 2006 at 1340 m altitude, A. Tinaut leg. The holotype and 24 paratype workers are stored in the author’s collection. Two specimens of the paratype series are stored in the collection of the Museo Nacional de Ciencas Naturales of Madrid (Spain) and the Museum of Geneva (Switzerland) besides two other specimens stored in Dra. Dolores Martínez (Univ. Complutense, Madrid, Spain) and Dr. Aktac (Anatolia, Turkey) private collections.

Etymology

The name is dedicated to the region of Anatolia (Turkey).
