Figures 9A–B

Type species. Yllenus hamifer Simon, 1876 .

Documentation studied. Comparative diagnostic drawings of 21 species in Prószyński (2016a) and original literature.

Etymology. Named in honor of prominent arachnologist – Dr. Y.M. Marusik [MARUS-ik-YLL- US], co-author of the big monograph of the genus Yllenus , the editor of many of my publications and a personal friend. Grammar gender - masculine.

Diagnosis. General characters shared with remaining genera of YLLENINES (see above), but palps and epigyne very special.

Palp. The tip of cymbium striking by being drawn into long, anterior "tail", arching above bulbus and serving as guide to embolus, the latter's hair thin and very long. Bulbus relatively small. Conductor very unusual, crescent shaped, broad and robust, in majority of species larger than bulbus. Palpal femur broad, crescent shaped, tibia short with large tibial apophysis, articulating with corresponding plate-like outgrowth of the cymbium's postero-vental angle ( Fig. 9A ).

Spermathecae set transversally, flattened oval, small and simple but with developed posterior part, often coiled and set parallel to epigyne's axis. Copulatory ducts thin walled, long but twisted into tight and compact, double spiral ( Fig. 9B ). The length of ducts seems to be correlated with the length of embolus of male.

Remarks. The description of this genus upgrades, without other changes, previously described group of species Yllenus ( hamifer group) ( Prószynski, 1968: 430., Logunov, Marusik 2003 b: 118).
