- Agroeca maghrebensis Bosmans, Robert, 1999, Bulletin Di L' Institut Royal Des Sciences Naturelles De Belgique Entomologie 69: 27-29.
Description
(Figs 5-8)
Materials Examined
Algeria Tamarisk along Oued Sahel R. Bosmans
Diagnosis
Diagnosis: Males of this species are easily distinguished by the dorsal angularity on the male palpal tibia, females by the epigyne with median depression with parallel margins and x-shaped pattern of copulation ducts.
Discussion
Remarks: The male Figured by Simon (1932) as the male of Agroeca annulipes, Sim on 1878 apparently belongs to the species described here.
Description
Description: Measurements: Male: Total length 4.0; carapace 2.06 long, 1.68 wide. Female: Total length 4.6-6.4; carapace 2.32-2.84 long, 1.72-2.40 wide. Colour and spination as in Agroeca annulipes. (Figs. 5-6): Tibial apophysis straight, with distinct dorsal angularity; median apophysis hooked, distal part strongly pointed; wide basal part of embolus visible in anteromedian part of bulb, gradually narrowing, curved in antero-dorsal direction. Epigyne (Fig. 7): Longer than wide; with large median depression, posteriorly truncate, anterior half with narrow median septum; depression often filled with concretions (“copulation plugs”); x-shaped pattern of touching copulation ducts visible in transparency.
Vulva (Fig. 8): Copulation ducts semi-circular, touching in middle; spermathecae not wider than copulation ducts.

Distribution
Distribution: Algeria, Morocco, Tunisia. Not as coastal as A. annulipes.
Biology and Ecology
Ecology: Adult in winter. Males were collected from November to February, females from November to May.
Description
(Figs 9-12)
Diagnosis
Diagnosis: Besides the copulatory organs, this species is easily distinguished from both other Agroeca species occurring in the Maghreb by its yellowish brown cephalothorax and the uniform legs with no annulations.
Description
Description: Measurements: Male: Total length 5.0-5.4; carapace 2.34-2.44 long, 1.82-1.92 wide. Female: Total length 5.3- 7.6; carapace 2.56-2.64 long, 2.02-2.16 wide. Colour: Carapace yellowish brown with narrow black margin and anastomosing, radiating dark brown striae; legs yellowish brown, not annulated; abdomen with central reddish brown band, laterally darker. Palp (Figs. 9-10): Tibial apophysis relatively short; median apophysis large, terminally with elongated hook. Epigyne (Fig. 11): As long as wide, with large anteromedian depression with triangular antero-median septum; depression often filled with secretions (“ copulation plugs”). Vulva (Fig. 12): Copulation ducts c-shaped, widely touching in middle; spermathecae not wider than copulation ducts.
