The species name is a noun in apposition and refers to agricultural fields where the species was exclusively collected. Diagnosis. Both sexes of Zodarion agricola spec. nov. are easily recognized by the prosoma with contrasting coloration: dark cephalic and pale thoracic. Males are further diagnosed by the long retrolateral tibial apophysis with recurved, toothed terminal part, females by the rounded antero-median process of the epigyne. By the elongated tibial apophysis, the shape of the tegular apophysis in the male and the antero-median epigynal pit in the female, the species belongs to the Z. elegans group defined by Bosmans (1997) .

Distribution . Central part of North Algeria , wilayas Algiers , Bouira and Bejaia . The species is present only in some Algerian agro-ecosystems where collections were made at regular intervals ( Fig. 13 ). Ecology . The species was mainly collected in agricultural habitats such as wheat fields and oilseed rape fields and has no preference for one or the other habitat; it is more abundant at the field edges ( Bouseksou et al. , 2015 ). The species is the dominant Zodarion in Olea europaea groves, an old but important Mediterranean ecosystem. Other species sampled were: Z. algiricum (Lucas, 1846) , Z. kabylianum Denis, 1937 and Z. ludibundum Simon, 1914 . Males and females were collected from May to October, except for one male collected in March ( Fig. 14 ). There is a peak in June and one in September, suggesting there are two generations per year.
