Diagnosis

The species described below could be assigned to Canariphantes based on the similarity with other congeners by showing poor leg spination, basically same conformation of the embolic division, a compact epigyne with a relatively short proscape and a reduced median part of the scape. The new species differs from all known congeners by the presence of a trichobothrium on metatarsi IV, a modified palpal tibia, as well as the shape of the distal part of the lamella characteristica in the male. The male seems to be especially similar to the East Mediterranean C. nanus (Kulczyński, 1898), but differs by a simple, unmodified paracymbium; the female is distinguished by a shorter and wider proscape. The shape of the epigyne is most similar to that of C. relictus Crespo & Bosmans, 2014, from the Azores (Crespo et al. 2014), but differs by the proscape base not being narrowed, as well as by the shape of the posterior median plate which shows a small invagination anteriorly, vs divided into two lobes in C. relictus .

Etymology

The specific epithet is a noun in apposition, referring to the presence of a trichobothrium on metatarsi IV, this not being typical of this genus. The name derived from both Latin ‘ trichobothrium ’ and ‘ fero ’, meaning ‘bearing’.
