Tribasodites bedosae
species-group
Diagnosis.
Cavernicolous
Tribasodites
with slender habitus and elongate antennae and legs. Males of all, except
T
.
abnormalis
sp. nov.
, have strongly modified antennomeres VIII–XI. A few species have strongly reduced eyes. Metaventrite modified, often with a pair of rows of dense setae anterior to metacoxae, or setae tufted instead of arranged in rows, or occasionally only sparsely covered.Aedeagus usually with median lobe split apically, with broad dorsal lobe, parameres attached to base of the median lobe, with distinct basoventral projection. Females lack any modification, and can be properly identified only if associated with the males, or sometimes by a combination of the forms of tergite VIII, sternite VIII, and genital complex.

Comments.
Except for
T
.
abnormalis
sp. nov.
, which has simple antennae and modified vertex, all males of this group are morphologically similar to each other. They can be separated only based on a combination of the following features: (1) shape of the aedeagus, (2) presence/absence of the pronotal lateral spines, (3) setation on metaventrite, (4) shape of the antennomeres VIII–XI, and (5) their distribution. An identification key is provided below.
