Type material. Male holotype, female paratype. PORTUGAL. Coimbra district: Coimbra, botanical garden, 2005, L. Crespo leg. ( SMF).

Etymology. The name is a noun in apposition and is derived form the area where it occurs, Costa da Prata.

Diagnosis. This species belongs to the rubidum group. It is closely related to Z. costablancae but differs in the overall dark brown colour and smaller size. Males can further be distinguished by the wider tibial apophysis. Females are distinguished the by shorter plate of the epigyne.

Description. Male. Total length 2.2–2.6 mm; prosoma 1.0–1.5 mm long, 0.7–1.0 mm wide. Colour. Carapace dark brown, femora dark brown, other leg segments yellow, sternum dark brown, coxae light brown, abdomen dorsally dark brown, ventrally pale, laterally pale, palpi dark brown. Palp. Tibial apophysis broad, slightly curved and bluntly pointed terminaly with a process on retrolateral side ( Fig. 7 ). Median apophysis short and U-shaped. Embolus broad terminally oblique ( Fig. 8 ).

Female. Total length 2.7–3.7 mm; prosoma 1.2–1.7 mm long, 0.7–1.1 mm wide. Further as in male. Epigyne: Median plate 1.9 x wider than long, with paired openings separated by a septum. Anteriorly with a wedge-like structure ( Fig. 9 ). Vulva with separated small round receptacula

and irregular ducts as in Fig. 10 .

Remark. Re-examination of the material from Pekár & Cardoso (2005) revealed two individuals of this species previously assigned incorrectly to Z. atlanticum .
