Temnothorax tuberum

Identification
Colour varies from entirely pale yellowish brown with the head pale to almost black and the dorsum of the gaster brownish. The antennal clubs are brown to brownish black contrasting with the rest of the funiculus. The head and clypeus are longitudinally striate and the alitrunk rugose. The petiole node has a distinct but short truncate dorsal area; propodeal spines are very short but quite distinct. Length: 2.3-3.4 mm (Collingwood 1979).

Distribution
A common and very widely distributed species in the mountains of Central Europe from Spain to the Caucasus and North Italy to Central Sweden (Collingwood 1979).

Biology
Collingwood (1979) - This species characteristically nests in small single queened colonies under stones and in rock crevices. In Scandinavia it is restricted to warm lowland habitats. The alatae are found in July and August.

The original and very brief description was based on Swedish material but the types are lost. Most Scandinavian samples have dark heads and could be referred to the supposed species L. nigriceps Mayr, 1855. In England where L. tuberum is locally abundant along the south coast, the colour tends to be uniformly pale but samples also occur with dark heads and there are no structural differences between dark headed and light coloured series.

Type locality(-ies): “Gotland (44 Fundorte, 47 Proben): 2, 3, 11, 12, 31, 32, 38, 39, 41, 43, 68, 72, 75, 79, 79*, 80, 81, 91, 103, 107, 108, 111, 192, 193, 194, 206, 207, 217, 218, 220, 221, 221*, 225, 226, 228, 229.

Oeland: (19 Fundorte, 21 Proben): 2,b, 3, 9, 12,c, 15,c, 15,e, 18,a, 18,f, 22, 27,e, 35,d, 35,h, 36,a, 36,c, 41,b, 42,b, 51,c, 52,b, 55, 57,a, 69,c, 80,c” (for details of these localities see Karawajew, 1930, pp. 110–144).

Original Karawajew label(-s): “Leptothorax (Leptothorax) / tuberum F. v. nigricephala Kar. / typus. Gotland, H. Lohmander / leg. Karavaiev dt.”; “Leptothorax (Leptothorax) / tuberum F. v. nigricephala / Kar. typus. Oeland, Loh- / mader leg. Karavaiew det.”.

Material: SYNTYPES, 12 w, 2 q, 1 m (newly mounted, IN 314/6/1), 1078 w, 61 q, 40 m, 12 pupae (in alcohol, IN 314/BAMS1/Karaw62, 64).

Notes. Karawajew (1930, 1931) had investigated abundant material from Sweden (including Islandes Gotland and Öland) collected by H. Lohmander. He had recorded for these territories only three species from the former genus Leptothorax: L. acervorum (F.), L. muscorum (Nyl.), and L. tuberum nigricephala (for the details of the taxonomic history of this genus see Bolton 2003). Thus, any material of var. nigricephala collected by Lohmander in Sweden and preserved in Karawajew’s collection could be considered as syntypes of this taxon.

Taxonomic Notes
Salata & Borowiec (2019): Results presented by Prebus (2017) suggest that the tuberum species group (sensu Cagniant and Espadaler 1997) and unifasciatus species group (sensu Bernard 1967) are paraphyletic. In both cases species groups were defined based on West-Mediterranean taxa. Only two Greek members of the tuberum species group were included in analysis presented by Prebus (2017): Temnothorax nigriceps and Temnothorax unifasciatus and they created a separate cluster. Confirmation, if the tuberum species group as defined by us here is a natural, monophyletic group requires further studies.
