Diagnosis (according to Gruber & Martens 1968, slightly modified)
Subspecies of N. bidentatum with large, arched dorsal hump on male Ch basal article, and large, apically, sagittally shallowly bifid, quarter moon-like Ch-Apo, ~2.4 times as high as wide. Pa-Fe distinctively club-shaped (Pa-Fe min:max width ~1:3.5), with 3 stout spines in distal Pa-Fe quarter, spine 2 the largest and longest. Pa-Pt Apo equilateral triangular with rounded apex. Pa-Ti with conspicuous proximal dorsomedial hump. Glans isosceles triangular, terminally rounded-truncated. Rec sem of 1 tubular and 12 elongated balloon-like vesicles.

Remarks
The type locality Comana Vlasca in Romania ( Roewer 1914) is erroneous, since besides N. b. sparsum (sic! not described by Roewer 1914), the type series also contains N. b. bidentatum and N. triste , both endemic to the Eastern Alps ( Gruber & Martens 1968: 143). Later, Roewer (1951) designated a type specimen from the type series from an unknown locality, but the mixed composition of the type series remained unresolved ( Gruber & Martens 1968). Thus, there was a need to clarify the type locality ( ICZN 1999: Art. 75.3.1.). Respecting both Roewerʼs drawing of the male Ch characteristic of individuals in the Karawanken/Karavane Mts and the syntopy of the Roewerʼs type specimens with N. triste, Gruber & Martens (1968) redescribed the nominal subspecies N. b. bidentatum upon a neotype ( Gruber & Martens 1968: figs 4−6) from Bärental, Carinthia, Austria (not mapped in Gruber & Martens 1968: fig. 24). Bärental is considered the type locality of the type subspecies. However, according to our findings the figured Pe tip from Leutschach/Lučine, Styria, Austria ( Gruber & Martens 1968: fig. 3), considered under the type subspecies, belonged to N. b. schmidti ssp. nov. All so far published evidence on N. b. bidentatum in Slovenia, Croatia and NE Italy ( Hadži 1927, 1928; Gruber & Martens 1968; Martens 1978; Novak & Gruber 2000; Komposch & Gruber 2004; Novak 2004a, 2004b, 2005b, 2005c; Novak et al. 1984, 1995, 1996, 2002, 2006, 2017) refer to other taxa. The type series deposited in Naturhistorisches Museum Wien ( Gruber & Martens 1968) also includes N. b. schmidti ssp. nov. See remarks under N. pluridentatum stat. nov., N. b. schmidti ssp. nov., N. b. gruberi ssp. nov. × N. b. schmidti ssp. nov. and N. b. martensi ssp. nov. × N. b. schmidti ssp. nov.
Distribution
The South-Eastern Alps: Austria, Slovenia ( Gruber & Martens 1968; Martens 1978), perhaps endemic to the Karawanken/Karavanke Mts. Vertical distribution (incomplete data): 980−1407 m a.s.l. (partly Gruber & Martens 1968 and Martens 1978; this work). Type locality: Bärental/Zavrh−Rute (46.47° N, 14.15° E, 980 m a.s.l.) near Feistritz im Rosental/Bistrica v Rožu, Carinthia, Austria.
Ecology
Montane subspecies of N. bidentatum inhabiting submontane and montane neutrophile fir forests within the area of distribution of the montane beech forests, dominated by Abies alba Mill. , with a great admixture of Picea abies (L.) H.Karst. and Fagus sylvatica L. Phenology : adults probably eurychronous.
