Nomen dubium.

Type series

Lost. Type locality: Russia, Kamtschatka, Ustj-Kamtschatsk, large island, 2 Jun. 1908, 1 specimen (Glas 21) (based on Thor 1926: pl. 11 fig. 3, obviously a female). No material available.

Remarks

In the original description, Thor (1926) recognized a similarity to L. porosa (without stating which characters) and to L. vigintimaculata (in colour pattern). From the description and an analysis of the figures given there ( Thor 1926: pl. 11 figs 1–3: palp, misshaped III-L, and genital field), the following additional details are noted: large in size (idiosoma L/H 1500/1200); gnathosomal and genital bays very large; Ac at their tips rounded (instead of subrectangular); ventral seta P-2 not far from distal end, medial setae at distal end of P-3 equidistant; P-4 little curved, distally narrowed, ventral setae far away from each other, sectors 26, 48, and 26%. No data on legs (except for the description and depiction of a malformation of III-L in the single available specimen).

The description of this species, based on a single, malformed specimen, does not include information sufficient to define diagnostic characters; an interesting feature is the large centroventral sector of P-4, not found in any specimen of the Lebertia porosa aggr. treated here. Lebertia porosa distans cannot be interpreted as a junior synonym of L. porosa (as proposed in Viets 1956), and it must be considered a nomen dubium.
