Description.

Female ( Figs 1-2 , 5-10 ). Length 620, width 429 (n=1).

Shape oval and pentagonal, two pairs of rounded horns present at anterior margin of idiosoma, one pair of incisions located below coxae IV, posterior margin of idiosoma rounded, colour brown.

Dorsal idiosoma ( Figs 1 , 5 ). Along whole inner line of the idiosoma, marginal shield is completely separated from dorsal shield by a distinct structural line ( Fig. 1 ). Dorsal shield with one elongated and well sclerotised line. Dorsal setae T-shaped (anchor shaped), mostly placed around middle and posterior parts of idiosoma. The posterior part of the idiosoma is significantly narrowed with deep lateral and marginal incisions are located below level of coxae IV. The inner part of the idiosoma has V-shaped supported marginal furrows. The dorsal shield of idiosoma covered by oval pits in various sizes. Marginal shield large, without any setation or sculptural pattern, and the outer edge of marginal shield is wavy with several small cavities ( Fig. 5 ).

Ventral idiosoma ( Figs 2 , 6-7 ). Sternal shield smooth ( Fig. 2 ). Three pairs of T-shaped sternal setae are situated around genital opening. Genital shield has shallowed pits and is almost oval with a relatively thin front. One pair of deep lateral and marginal incisions are located below level of coxae IV. Posterior part of ventral shield covered with oval pits, remaining parts smooth. Anal opening small ( Fig. 6 ). Peritreme with two loops and not clearly visible. Base of tritosternum narrow, tritosternal laciniae subdivided into four branches, two central branches apically pilose and two lateral branches marginally pilose ( Fig. 7 ).

Gnathosoma ( Figs 8-10 ). Corniculi short and horn-like shaped. Internal malae subdivided into several smooth branches. Hypostomal setae about in equal lenghts, h1 smooth and located the anterior margin of gnathosoma, setae h2-h4 marginally serrate ( Fig. 8 ). Epistome triangular shaped and pilose ( Fig. 9 ). Movable digit of chelicera shorter than fixed digit ( Fig. 10 ).

Male ( Figures 3-4 , 11 ). Length 686, width 470 (n=1).

Marginal shield wide, with many oval pits unlike female specimen. Ornamentation and chaetotaxy of dorsal shield ( Figs. 3-4 ) as in female specimen. Sternal shield covered by oval pits are mostly placed around anterior and lateral parts of genital opening. Genital shield oval and located between coxae II ( Fig. 11 ).

Nymphs and larvae. Not found.

Distribution: Austria, Czechia, Hungary, Iran, Italia, Romania, Slovakia ( Kontschán, 2021), Turkey (present study).
