Type material.

Slovakia, Považský Inovec Mts.: 1 ♀ (IZSAV, holotype) - 13. 10. 2012, Hrádok Village, Hrádocká Dolina Valley, edge of broad-leaved deciduous forest, decaying wood-destroying fungi, altitude 290 m, leg. P. Mašán; 4 ♀♀ (IZSAV, paratypes), with the same collection data as in holotype.

Diagnosis.

Dorsal shield strongly sculptured, scrobiculate, with a series of interconnecting ridges. Dorsal setae of different length, relatively thin and variously curved; setae J2 long, with tips reaching clearly beyond bases of following setae J4; setae Z2 notably longer than Z1 and Z3. Pseudo-metasternal platelets relatively well developed, subequal or slightly larger than metapodal platelets. Opisthogastric soft integument with six pairs of setae; setae JV5 lengthened, with tips reaching anal aperture.

Description.

Female. Idiosoma oval to egg-shaped, narrowed anteriorly, 405-460 μm long and 270-325 μm wide. Dorsal shield strongly sclerotised and coarsely ornamented, scrobiculate, covering whole dorsal surface, and bearing 29 pairs of setae; vertex with anterior margin denticulated. Dorsal setae well differing in length, relatively thin, curved, sparsely covered by very minute spines, inserted in small basal papilla-like tubercles; setae j1-j4, z5, z6, Z1, Z3, s1, s2, S2, S3, and r3-r5 notably shorter than other dorsal shield setae; setae j1 lanceolate and conspicuosly spinate; posterior dorsocentral setae long, J2 and J4 with tips reaching beyond bases of J4 and Z5, respectively. The length of some selected dorsal setae as follows: j5 83-92 μm, j6 92-102 μm, J2 105-118 μm, z5 25-30 μm, z6 29-40 μm, Z1 38-46 μm, Z2 78-92 μm, Z3 45-55 μm. Sternal shield subquadrate, 62-70 μm in length and width (at level of st2), reticulate on surface, with two pairs of setae (st1, st2). Pseudo-metasternal platelets relatively large, rounded, bearing a pair of sternal setae (st3). Metasternal setae (st4) on soft integument. Epigynal shield 70 μm wide, oblong, with reticulate pattern and a pair of genital setae (st5). Postgenital sclerites present, partly fused behind posterior margin of epigynal shield. Metapodal platelets small, suboval. Peritremes and peritrematal shields normally developed. Ventrianal shield 125-140 μm wide and 100-115 μm long, almost hexagonal, well reticulate, having three circum-anal setae and anus in its posteromedial portion. Ventrally situated setae smooth, needle-like, about 25 μm long, except JV5, markedly elongated, 60-67 μm in length. Epistome subtriangular, with rounded apex. Fixed digit of chelicera with three small teeth on proximal masticatory area. Other gnathosomal structures and leg chaetotaxy typical of genus.

Etymology.

The new species is named in honour of my dear older sister.
