Head (Fig. 1) subrectangular, with evenly rounded occipital corners. Head width equal in front of and behind the eyes. Eyes comparatively small, situated at midpoint of head. Frontal triangle distinctly delimited and well depressed. Scapes short, not reaching occipital corners. Mesosoma flat, outline in lateral view over a long distance straight, with shallow mesometanotal depression. Mesonotum at place where wings ofalate would insert with slight, but in dorsal and lateral aspect well visible crests; more prominent than in congeners. Propodeal spines broadly attached, longer than broad, in lateral view more or less straight caudad oriented, with pointed tips. In dorsal view, spines slightly convex, distally only minimally divergent. Propodeal spine index (cf. Buschinger1966) 1.3 - 1.6, the spines thus being comparatively short. Petiole short and high, node triangular, its anterior face markedly concave (Figs. 3, 4, 6) in lateral view, its posterior face also slightly concave, straight, or appearing a little bit convex with straight or slightly concave outlines. Top of node acute. In dorsocaudal view, upper part of node distinctly convergent, with sharp, medially distinctly impressed ridge. Anterior part of dorsal petiolar outline with prominent corners, well visible in dorsal or lateral view. Subpetiolar process well developed, pointing anterioventrad. Postpetiole rounded and lacking any conspicuous ventral appendage. Erect hairs relatively short (60 - 80 µm). Scapes only with subdecumbent, not erect hairs. Tips of hairs blunt. Petiole with a total of c. 8, postpetiole with c. 10 erect setae. Sculpture of head, mesosoma and waist mainly densely reticulate, without any stronger rugae or other sculpture elements. Color of body evenly dark brown, without any lighter spots, appendages distinctly lighter, mainly light brown to orange-brown.</paragraph>

Perhaps, at the end of the Ice Age, a comparatively rapid colonization of the area may have occurred, along the valleys that commonly extend in North-South direction. We may speculate that the populations in the comparatively short time have not yet finally settled; that certain species are still increasing, others diminishing due to competition.
