Leptothorax (Leptothorax) tuberum F. var. nigricephala Karawajew, 1930: 146 , w, q (also described as a new taxon: Karawajew, 1931: 212).

Current status: junior synonym of Temnothorax tuberum Fabricius, 1775 , w, Sweden. Synonymy: Radchenko, 1995: 14 (as synonym of Leptothorax tuberum ; see also Bolton, 2003).

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/ BAMS 1/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.
