Diagnosis. This species belongs to the „ rubidum “ group sensu Bosmans (1997). It is closely related to Z. viduum Denis 1937   , Z. costablancae Bosmans 1994   and Z. machadoi Denis 1939   . Males of this species are distinguished from these species by shape of tibial apophysis, which is wide at base and gradually tapering towards tip. Females differ in shape of posterio­lateral margins of epigynal plate that are convergent.

Description. Male. Total length 2.39 mm (SD=0.14, n=10), prosoma 1.25 mm (SD=0.06, n=10) long, 0.87 (SD=0.03, n=10) wide. Colour: Prosoma, chelicerae and sternum brown. Legs yellow but femora I and II brown. Opisthosoma dorsally dark sepia with one whitish spot above spinnerets, ventrally pale. Palp (Figs 56): tibial apophysis broad gradually tapering, curved anterio­dorsally, distally pointed. Basal part of bulbus protruding. Retinaculum with distal end rounded and flattened. Embolus and disal tegular apophysis straight and truncate.

Female. Total length 3.19 mm (SD=0.32, n=10), prosoma 1.34 mm (SD=0.08, n=10) long, 0.92 (SD=0.06, n=10) wide. Colour: as in males but femora III and IV distally light brown. Epigyne (Figs 78): with two pouches. Anterior margin with a wedge­shaped structure. Posterior margins convergent. Width of epigynal plate twice as long as distance between inner ends of posterio­lateral margins.

Distribution. In continental Portugal it is known from the centre of the country, in the Azores from Pico and Faial islands ( Fig. 16 View FIGURES 13–20 ).

Etymology. The name is an adjective derived from the Atlantic Ocean in whose proximities it is found.
