An updated checklist of spiders (Araneae) of the Faroe Islands

This study updates the previous checklist of Faroese spiders published in 2004. Fifteen species
are added to the list: Amaurobius fenestralis (Ström, 1768), A. similis (Blackwall, 1861), Zygiella
x-notata (Clerck, 1757), Allomengea scopigera (Grube, 1859), Baryphyma trifrons (O. P.-Cambridge,
1863), Erigone dentigera O. P.-Cambridge, 1874, E. whymperi O. P.-Cambridge, 1877, Halorates
reprobus (O. P.-Cambridge, 1879), Microlinyphia pusilla (Sundevall, 1830), Porrhomma campbelli
F.O.P.-Cambridge, 1894, P. pallidum Jackson, 1913, Silometopus ambiguus (O. P.-Cambridge,
1905), Psilochorus simoni (Berland, 1911), Tetragnatha extensa (Linnaeus, 1758), and Parasteatoda
tepidariorum (C.L. Koch, 1841). Nine species are deleted from the checklist. While Araneus
diadematus Clerck, 1757, A. quadratus Clerck, 1757, and Nuctenea umbratica (Clerck, 1757) have
been repeatedly introduced to the Faroes they have failed to establish and are deleted. Crustulina
guttata (Wider, 1834) and Walckenaeria obtusa Blackwall, 1836 are considered accidental imports
unable to breed in the islands and are also deleted. Bolephthyphantes index (Thorell, 1856) and
Tmeticus affinis (Blackwall, 1855) are assumed erroneously reported from the islands and are deleted
from the list along with Agyneta ramosa Jackson, 1912 and Ozyptila atomaria (Panzer, 1801) which
were found to be misidentified upon re-examination of museum specimens. The status of Porrhomma
egeria Simon, 1884 in the Faroes is uncertain and is maintained on the list. At least 114 spider species
have been recorded in the Faroes, however only 90 meet the criteria of the checklist
