Abstract. A new ground spider, Berinda idae Lissner spec. nov. is described from material collected in Kalymnos and Nisyros ofthe
Dodecanese Islands, as well as Santorini and Christiani oftheThira island complex, Cyclades, Greece.The affmity ofthis species to its
congenersisbrieflydiscussed.

Diagnosis. The male of the species described here differs
from those ofall other Berinda species by possessing a small,
triangulär tibial retrolateral apophysis, about one fifth the
length of palpal tibia. In all other Berinda males the tibial
apophysis is considerably longer or, in the case ofB. amabilis
Roewer,1928,shortbutwith an additionalfingerTikepatellar
apophysis (Panayiotou et al. 2010). The shape of the mem-
braneous part(sac orbladder,sensu Panayiotou etal.2010) of
the conductor is highly distinctive in each species being ap-
proximately triangulär in retrolateralview in the present spe-
cies.The female of B. idaeLissner spec. nov.possesses a short,
rectangularepigynal hood,abouttwice aswide as long,unlike
those ofanyother known Berinda females.The spermathecae
are oval in shape and distinctly separated. In the five already
described species (female of the sixth B. cooki is unknown)
the spermathecae are almost touching or overlapping,and all
those species, except B. amabilis, have kidney-shaped sper-
mathecae.
