In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.Įstimated Abundance Relative abundance based on number of AntMaps records per species (this species within the purple bar). Palaearctic Region: Albania, Austria, Bulgaria, Czech Republic, Greece, Hungary, Iberian Peninsula, Israel, Malta, Montenegro, North Macedonia, Romania, Russian Federation, Slovakia, Slovenia, Spain, Turkey, Ukraine.Ĭheck data from AntWeb Countries Occupied Number of countries occupied by this species based on AntWiki Regional Taxon Lists. 2010).ĭistribution based on Regional Taxon Lists It is known in Bulgaria in a small number of localities (Dobrudzha, Thracian Lowland (Svilengrad), Struma Valley (Petrich, Sandanski) and Burgas) (Forel 1892, Atanassov and Dlussky 1992, Lapeva-Gjonova et al. Lapeva-Gjonova & Borowiec (2022) - Proceratium melinum is rarely collected due to its subterranean lifestyle and small colonies, although it is widespread in the Palaearctic. melinum appears to be from southern Poland (Cracow). The northernmost distributional record for P. The account, however, represents the southernmost record for this species and appears as biogeographically plausible. Kugler (1988) reports this species from Israel, a country from which we did not see any specimen.

The known distribution of this species in the Iberian Peninsula is detailed by Tinaut & Martinez-Ibanez (1998). Key to Proceratium workers of the worldĬentral and Southern Europe from South Spain to Russia, Turkey, and Israel.

Differing from its ingroup species, Proceratium confinium, in the worker, mainly by the frontal carinae separate instead of very close to each other, by the antennal scapes shorter and by the fore basitarsi longer than the mid basitarsi instead of subequal and from its outgroup, Proceratium morisitai, in the worker and gyne, by the head rugosopunctate instead of granulate and by the second tarsomere of hind leg about 1/5 longcr than the pretarsus instead of about as long as the pretarsus, and, in the male, by the IGR = 0.62 instead of IGR 0.68. Poldi (1963, cited in Hölldobler and Wilson, 1990) described how the queen plugs the nest entrance with her rounded and unmodified first gastral segments, a behaviour seen in phragmotic species.Ī member of the pergandei clade. Carebara oertzeni was also found in this same sample.

In Albania (Purkart et al., 2019) it was found near a canyon of the river Lengaricës, where rocky slopes are covered with small areas of forest-steppe, from a sample of rotten wood, leaf litter and soil taken from a decaying tree, and the collected material was then heat extracted from the sample using Tullgren funnels. Sysphincta europaea rossica Arnol'di, 1930Ī wide ranging Palaearctic species.
