Koch, 1835) Eueremaeus oblongus Weigmann 2006 , p. 219 , fig. 116e. Eueremaeus oblongus Seniczak et al ., 2014 , p. 83 , figs 1-6. Parco Naturale delle Alpi Marittime: AB, AND-I sparse. General distribution: Northern, southern Italy ; Italian, Swiss, Austrian Alps; Holarctic, Oriental. Habitat preferences: silvicolous; xerophilous. Remarks: A morphological differentiation between E. oblongus and E. valkanovi (Kunst, 1957) is given by Weigmann (2006) , but in the present material the different characters are not always clearly distinguishable. The specimens show a high variability and a mosaic pattern of characters in-between the species. A synonymy of E. valkanovi is suspected by Subías (2004 , electronic update 2021) and Seniczak et al . (2014) .
