Type material. Male holotype, female paratype. SPAIN. Valencia district: Montcada, 5 September 2008, S. Pekár leg. ( SMF).

Etymology. The name is dedicated to César Monzó, a colleague who collected this species for the first time.

Diagnosis. This species belongs to the pusio group. It is very similar to Z. pusio both in colour and size. Males are distinguished by the shape of the terminal part of the tibial apophysis. Females are distinguished by the presence of a roof-like structure in the median plate of epigyne.

Description. Male. Total length 1.7–2.3 mm; prosoma 0.9–1.1 long, 0.7–0.8 wide. Colour: Coxae pale, carapace yellow, legs segments yellow, sternum pale, abdomen dorsally brown, ventrally pale, dark spot around eyes, sternum with thin brown margin. Palp. Tibial apophysis with ventro-lateral lobe at base, bent but not hooked terminally, on the retrolateral side with a tiny pointed terminal apophysis ( Fig. 3 ). Distal part of median apophysis slen- der, elongated and pointed ( Fig. 4 ). Embolus rather straight and S-shaped.

Female. Total length 2.3–2.8 mm; prosoma 1–1.2 long, 0.7–0.9 wide. Colour as in male. Epigyne. Paired openings surrounded anterio-laterally by sclerotised rims converging in the centre and forming a roof-like structure in the centre of the plate ( Fig. 5 ). Vulva with rounded receptacula separated by 2.5x their diameter, ducts short Sshaped ( Fig. 6 ).

Other material. SPAIN. Valencia district: Xilxes, Castellón, 26 October 2009, 43, C. Monzó leg. (CSP); 10 March 2010, 5Ƥ, C. Monzó leg. (CSP); Massalfassar, 7 September 2008, 1Ƥ, S. Pekár leg. (CSP); Bétera, 5 September 2008, 113+2Ƥ+5j, S. Pekár leg. (CSP); 10 March 2010, 4Ƥ, C. Monzó leg. (CSP).

Distribution. Known only from the Valencia district, from disturbed areas, such as orchards and parking lots ( Fig. 17 ).
