(220SEdom) Seira domestica (Nicolet, 1841)

Lubbock (1869) was the first person to record Seira domestica from 'Millbank and Brixton prisons' (the former is the current site of Tate Britain). It has since been found in a small number of scattered localities, always in buildings. I found the specimen in the photo (Fig. 1) in an isolated farmhouse in Southole near Hartland in Devon in September 2001. Other confirmed localities are 'Hampstead, indoors' and 'water dish, Natural History Museum'!). Seira domestica is covered in rounded scales (Fig. 2), has a long claw on the foot (Fig. 3), and possesses a highly distinctive mucro with a single tooth, and a strongly crenulated dens (Fig. 4).
The records suggest that the species has a southerly bias. Bagnall would surely have found Seira domestica had it occurred in northern England.
