Female (from Grosses Kar, Salzburg) BODY. Length 1.70. CHELICERAE.

Pa article lengths in Table 5. OVIPOSITOR. Rec sem with 5 lobate, tubular-saccular vesicles (Fig. 11D). LEGS. Leg article lengths in Tables 5–6. Remarks We did not examine the original type material; for the current description, we used other specimens from the type location. Rec sem were found much different from the other taxa within the N. b. complex. Distribution Austria, endemite of eastern Central Alps (Gruber & Martens 1968; Martens 1978; Komposch 1999, 2009). Vertical distribution: 1325−2240 m a.s.l. (Komposch 1999, 2009). Type locality: Grosses Kar, near the Tappenkarsee Lake, Kleinartal, Salzburg (47.19° N, 13.32° E, 1760 m a.s.l.), Radstädter Tauern Mts, Austria. Ecology Nemastoma relictum stat. nov. is a montane to alpine species within the N. b. complex inhabiting forests below the krummholz zone, alpine meadows, spring-areas, and gravel and block heaps in the eastern Central Alps (Gruber & Martens 1968; Martens 1978; Komposch 1999, 2009) in 1325–2240 m a.s.l. (Komposch 1999). Phenology: evidence of adults from the end of May till the end of October, but probably eurychronous.
