Tectocepheidae Grandjean, 1954 Tectocepheus velatus sarekensis Trägårdh, 1910 Distribution: semicosmopolitan: Holarctic, Oriental and Ethiopian regions, Central America, Australia and Pacific Habitat: euryoecious species Obergurgl area: This species has been recorded in all investigated sites: pine forest at 2050 m (Zirbenwald), Nardetum at 2300 m (Schönwieskopf), Caricetum at 2600 m (Hohe Mut), Androsacetum alpinae at 2900 m (Liebener Rippe); previous studies: 1960–1980 m (hay meadows), pine forest at 2050 m (Zirbenwald), 2100–2190 m (dwarf shrub community), 2250–2340 m (alpine meadows with lichen communities), 2500 m (scree slope), 2550–2650 m (alpine meadows), 2800–3100 m (Androsacetum alpinae) Taxonomic remark: The taxonomic rank and position of “ T velatus. sarekensis ” is still unclear. Tectocepheus species are primarily parthenogenetic. Nübel-Reidelbach (1994) lumped together the characters of different and heterogeneous populations, and she postulated all studied populations—except of T. minor —as members of one large and polymorphic species, T. velatus . Weigmann (2002) studied morphological differences between different populations and distinguished distinct groups, tentatively ranked at subspecific level (also in Weigmann 2006). Based on molecular analyses of nucleotide sequences, Laumann et al . (2007) suggested that the different morphotypes of Tectocepheus evolved in absence of sexual reproduction, and that T. minor , T. velatus and T. sarekensis are best considered as distinct species. Tectocepheus velatus tenuis Knülle, 1954 Distribution: Germany, Czech Republic, European Russia, Central Asia Habitat: rather dry and sandy dune areas and heath Obergurgl area: pine forest at 2050 m (Zirbenwald), Nardetum at 2300 m (Schönwieskopf), Caricetum at 2600 m (Hohe Mut) Remark: See T. velatus sarekensis Tectocepheus velatus velatus (Michael, 1880) Distribution: almost cosmopolitan, including Antarctic and Subantarctic Islands Habitat: undifferentiated, euryoecious species Obergurgl area: 2050 m ...
