NIGHTINGALE ISLAND: Site 8, 1st Pond furthest from the path, 37 o 25 ' 616 ''S, 12 ° 29 ' 302 ''W, mire wetland with pool surrounded by Scirpus spp., 30.iii.–01.iv.2005, 15 females, Malaise trap, C. Hänel; Site 10, 3rd Pond close to top of path, 37 ° 25 ' 533 "S, 12 ° 29 ' 102 "W, mire wetland, Scirpus spp, fernbush spp. and mosses, 26–28.iii.2005, 46 females, Malaise trap, C. Hänel (BMNH, TCD, ZMBN). The species including parthenogenetic populations is redescribed by Saether (1975: 1032 as L. hudsoni Saether, 1975; 1990: 59). As mentioned by Saether (1990) the parthenogenetic populations from the subantarctic islands mostly show a higher chaetotaxy than in most specimens of L. minimus , particularly on the preepisternum. The range given in Saether (1990) is 5–15 preepisternals with non-parthenogenetic populations having 5–12 preepisternals. The population from Nightingale Island has 9 –16, 12 (30) preepisternals, the one from Gough Island 7 –16, 13 (26) preepisternals. Distribution. The species is known from all regions except Australia (Saether & Spies 2004) including the parthenogenetic populations of the subantarctic islands of Kerguelen, Marion, Prince Edward, Gough, Inaccessible and Nightingale (Saether 1990; Jones et al. 2003; Barber-James 2007). : Published as part of Saether, Ole A. & Andersen, Trond, 2011, Chironomidae from Gough, Nightingale and Tristan da Cunha islands, pp. 1-19 in Zootaxa 2915 on page 8, DOI: 10.5281/zenodo.206060 : {"references": ["Meigen, J.
