Remarks
In Slovenia, N. b. sparsum lives in the northeast, at the margins of the Pannonian basin (Martens & Gruber 1968; Martens 1978; Kovač 1997). The type series deposited in Naturhistorisches Museum Wien (Gruber & Martens 1968) also includes N. b. gruberi ssp. nov. distributed south of the Sava River in Slovenia and Croatia. All prior identifications of N. b. sparsum south of the Sava River (Novak et al. 1995, 2002; Novak 2005b) refer to N. b. gruberi ssp. nov. Martens (1978: 112) reported a sparsum -like population living in the mountain pine association (Hyperico grisebachii-Pinetum mugo Horvat 1938) on Mt. Veliki Snežnik (the peak at 1796 m) at least up to the altitude of 1650 m a.s.l. These individuals may refer to N. b. gruberi ssp. nov., N. b. martensi ssp. nov. or N. b. sneznikensis ssp. nov. Individuals from Bosnia and Herzegovina (Mt. Plasa, Jajce) and Dalmatia, Croatia (Split) (Gruber & Martens 1968) should be revised for identification. See remarks under N. b. gruberi ssp. nov. and N. b. gruberi ssp. nov. × N. b. schmidti ssp. nov., N. b. martensi ssp. nov. and N. b. sneznikensis ssp. nov.
Distribution
Central and eastern Europe: Austria, Bulgaria, Bosnia and Herzegovina, Czech Republic, Denmark, Hungary, Croatia, Montenegro, Romania, Russia, Slovakia, Slovenia, Serbia and Turkey (Gruber & Martens 1968; Staręga 1976; Martens 1978, 2006; Mučalica 1988; Klimeš 2000; Komposch 2002; Komposch & Gruber 2004; Schönhofer & Holle 2007). Vertical distribution: 120−1650 m a.s.l. (Komposch 1999; Komposch & Gruber 2004), in Slovenia 155–644 m a.s.l. Type locality: Sonnenberg (47.88° N, 16.31° E, 480 m a.s.l.), Leitha Mts, Burgenland, Austria.
Ecology
Nemastoma b. sparsum is a lowland and hilly land subspecies inhabiting various types of acidophilous and neutrophilous forests of Fagus sylvatica, Carpinus betulus L. and Quercus petraea (Matt.) Liebl., riverine forests, and thermophilous scrubs in north-eastern Slovenia, mostly on non-calcareous soils. Phenology: adults eurychronous.
