Holotype female: SW Slovakia, Borská Nížina Lowland, Šaštín-Stráže Town, Gazárka Settlement, Jubilejný Les Forest, elevation 175 m, in bark crevices of an old oak ( Quercus sp. ) heavily soaked with xylem sap, in a mixed forest with pines ( Pinus sylvestris ) and oaks, 10 August 2019 (leg. author) ; paratype female, with the same data as the holotype; type specimens were deposited in the Institute of Zoology, Slovak Academy of Sciences, Bratislava , Slovakia.

Diagnosis (Female)

Dorsal shield with 37 pairs of setae, including four pairs of marginal setae (r2‒r5); r6 and R1‒R6 and two pairs of submarginal setae (UR) on soft cuticle adjacent to lateral margins of dorsal shield; dorsal setae needle-like and long, usually projecting far beyond bases of following setae in longitudinal row; vertical setae (j1) straight, blunt, rod-shaped, and arranged on regularly curved vertex. Pre-anal setae incomplete, opisthogaster with only eight pairs of setae (JV1‒JV5, ZV1, ZV4, ZV5), of which only one pair (JV2) on ventrianal shield. Peritremes thin, with free anterior and posterior ends, each terminating in a stigma between coxae III and IV. Peritrematal shields narrow, each with short poststigmatic part connected to parapodal part of exopodal platelet. Anterior margin of epistome tricuspid, median cusp conspicuously larger than lateral cusps. Middle article of chelicerae long and thin. Pretarsi and claws of legs I distinctly smaller than those of legs II‒IV; tarsi I longer than tibiae I; legs shorter than idiosoma except well elongated legs IV; trochanter I with four setae. Minor duct relatively short and broad (not filiform).

As in Mašán (2023a), pages 462–466, figures 1–8.

Note

This species was described by Mašán (2023a), but its name is not available because the author did not indicate where the type specimens are deposited (ICZN Article 16.4.2).
