Diagnosis
Species within the N. b. complex with button-shaped Ch-Apo, and secretion field oriented frontally. Pa- Fe without spines, slightly club-shaped (Pa-Fe min:max width ~1:2.3). Rec sem with 5 lobate, tubularsaccular vesicles.
Material examined
AUSTRIA • 2 ♂♂, 3 ♀♀; Grosses Kar, the Koralpe Mts; 25 Oct. 2005; C. Komposch leg. (CK det.); PMSL.
Description (according to Gruber & Martens 1968, slightly modified)
Male (from Grosses Kar, Salzburg)
BODY. Length 1.55−1.60.
CHELICERAE. Ch with flat triangular dorsal margin in front of dorsal indentation; ventral margin straight, with minute triangular hump. Ch-Apo button-like, inferior and frontal margins straight, embracing a
90° angle, Ch-Apo dorsally round, secretion field with dense setae (brush) frontally (Figs 4C, 6C, 9C). Proximal article length 0.54, distal article length 0.53, max width 0.18, movable finger length 0.19.
PEDIPALPS. Pa-Tr dorsal margin high, oval, leaned distally; Pa-Fe distended distally (max:min width ~ 1.7:1), without spines. Pa-Pt with conspicuously convex ventral margin and finger-like medial Apo. Pa-Ti and Pa-Ta straight (Figs 5C, 6C). Pa article lengths in Table 5.
PENIS. Pe length 1.6, Pe basis ¼ Pe length, glans isosceles triangular (Figs 7C, 8C).
LEGS. Leg article lengths in Tables 5–6.
Female (from Grosses Kar, Salzburg)
BODY. Length 1.70.
CHELICERAE. Ch basal article with low-arched dorsal margin in front of indentation, and ventral lowarched concavity, Ch basal article length:width ~ 2.3:1 (Fig. 13C). Proximal article length 0.56, distal article length 0.55, max width 0.19, movable finger length 0.20.
PEDIPALPS. Pa short, ~ 2 mm long, Pa-Tr with high, isosceles triangular dorsal margin arched on the top, Pa-Fe distended distally (max:min width ~1.6:1), Pa-Ta short, Pa-Ta length:Pa-Ti length ~1:1.6 (Fig. 13C). 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.
