Type material. Holotype (♂): ITALY: Sardinia, South Sardinia province, Iglesias, Marganai , 700 m, 5 Aug - 13 Sep 2005, pitfall trap, G. Chessa leg. ( MSNV) . Paratypes: 1♀: same data ( CAT) ; 1 ♂ (specimen in very poor condition): same data but 30 Sep - 17 Oct 2005 ( CAT) ; 1 ♀ (specimen in very poor condition): Sardinia: South Sardinia province, Iglesias, Vecchia Cantoniera Marganai , 491 m, direct collecting, M. Bardiani, D. Birtele, P. Cornacchia & D. Whitmore leg. ( CAT) .

Diagnosis (♂ ♀). A Cybaeodes species differing from the other known congeneric in having the following dentition pattern of chelicera: promargin without teeth (Fig. 5) and retromargin with five teeth (Fig. 6; the other Cybaeodes species have promargin with two teeth and retromargin with three teeth). Male can also be recognized by the combined presence of two large and pointed apophyses of the embolar base and by the coiled shape of the laminate embolus; female differs from other known representatives of the genus by the shape of the epigyne, the shape of the epigynal anterior rim, the epigynal lobes and the long epigynal ducts. Etymology. It is an honour for me to dedicate this new species to my mentor in arachnology and friend Giulio Gardini, renowned pseudoscorpion specialist, to which I express my deep sense of gratitude and indebtedness.

Description (♂ ♀). Prosoma yellowish brown with fovea dark brown and sternum yellowish, chelicera yellowish brown, legs pale yellowish and opisthosoma white greyish to greyish. Prosoma longer than wide (Figs 1, 3). Eyes formula: ALE> PLE> AME> PME. Chelicera robust (Figs 2, 4); cheliceral promargin without teeth and with long stout hairs on the cheliceral rim (Fig. 5), cheliceral retromargin with five teeth: three contiguous in basal position (the first the smallest; the second and third the largest), two well separate teeth in median position (Fig. 6). Labium slighty longer than wide apically with hairs. Endites subrectangular, frontally rounded, with apical tuft hairs. Legs long with trochanters notched and patella spineless, tarsal claws with five teeth and spatulate hairs on the tarsal tips; leg spination as in Tables 1 and 2. Opisthosoma with very fine pubes- cence and an evident hairs tuft in the anterior part.

Measurements and morphological indices (due to the poor conditions of some specimens, only the holotype and 1♀ paratype were measured): total length: ♂ 5.86, ♀ 4.97; carapace length: ♂ 2.68, ♀ 2.07; carapace width ♂ 2.06, ♀ 1.59; carapace length/width ratio: ♂ ♀ 1.30; AME: ♂ 0.06, ♀ 0.04; ALE: ♂ 0.08, ♀ 0.07; PME: ♂ 0.05, ♀ 0.03; PLE ♂ 0.07, ♀ 0.05.

Male: all the spinnerets gnaphosid-like (cylindrical, elongate and bearing enlarged spigots), AS well separated at the base, MS contiguous and PS well separated at the base; spinnerets size: AS > PS> MS (Fig. 7).

Pedipalp tibia with long setae on ventral and lateral side; retrolateral tibial apophysis triangular longer than wide and apically pointed; tegulum wide with a well-defined rounded peak on the anterior edge; median apophysis moderately robust and elongate, apically rounded and with a spur located near the apex; wide embolar base with two large, robust and pointed apophysis; long and laminate embolus, curved and coiled in the distal part (Figs 9–12).

Female: all the spinnerets subconical, AS well separat- ed at the base, MS contiguous and PS well separated at the base; spinnerets size: AS > PS> MS (Fig. 8).

Epigyne with anterior ridge well defined and with central part thicker and semicircular shaped; atrium completely occupied in the central part by two slightly curved longitudinal lobes, contiguous in the middle part and separated in the upper and lower part; the two longitudinal lobes have inner and outer margins thicker and darkest, with the outer margins strongly curved to form two well-defined lobes in the upper lateral part of the epigyne (Figs 13–14).

Vulva with moderately thin insemination ducts strongly curved at the base (look like a question mark overturned) and small spermatechae located at the base of the longitudinal bands in the outer part (Fig. 15).
