: 387 (corrected spelling, original name based on the generic name
Cybaeus
, which was also misspelled as
Cybeus
by

: 206).

DIAGNOSIS:
Cybaeodes
can easily be recognized by the combined presence of gnaphosid-like anterior lateral spinnerets in males (but not females) and two ventral rows of modified setae on the anterior legs of both sexes. The extremely small eyes (see
Roewer, 1960
: Fig. la) seem also to be diagnostic (both of the cavernicolous species

molara
and the other, presumably epigean species), and we would not be surprised to find that blind, cavemicolous members of
Cybaeodes
occur in Mediterranean caves.
DESCRIPTION: To the detailed descriptions provided by
Roewer (1960)
and
Di Franco (1989)
, we can add that the trichobothrial bases bear several chevron-shaped ridges (
Fig
. 9
), that the tarsal organ is elongate, with a round opening and elevated receptors (Fig. 10), and that the male palpal tibia bears a small prolateral lobe (as in
Liocranum
and
Hesperocranum
).

SYNONYMY: Roewer's redescription of the genus can probably be ascribed to Simon's lack of
Cybaeodes
males and his association of the genus more closely with gnaphosids than with other liocranids.
