Until recently the ant Temnothorax albipennis was known as Leptothorax albipennis (=tuberointerruptus) and had been misidentified as Temnothorax tuberum in Britain. It appears that all mainland records of Temnothorax tuberum refer to T. albipennis (Orledge, 1998). Whether the Channel Islands records for T. tuberum are similarly in error is unknown, although they are included here on the T. albipennis map. Workers of T. albipennis are smaller than those of Leptothorax acervorum, and generally distinguishable from workers of the three other British Temnothorax species, by their combination of darkened antennal clubs, straight and relatively short propodeal spines, and rather poorly-defined darkening on their gasters.
British mainland records come only from southern England and from Wales. Most are from sites on or near the coast, a notable exception being the record from Castle Drogo, South Devon (Alexander, 1983). There are no confirmed records from Ireland.
On continental Europe T. albipennis has been recorded from The Netherlands, southern France, northern Spain, south and central Germany and central Italy.
