Holotype male: Tunisia, Monastir, 16 September, 1977, alga settled on stones of pier, netted from debris possibly mixed with human feces, leg. L. and S. Mahunka. - Paratypes: 6 ó, 9 oj data same as for holotype. Thoracochaeta tunisica sp.n. is closely related to T. fittkaui (Remmert, 1955), which was described from Egypt and reported from southern France and the Caroline Is. but latter data need revision. The wings of T. tunisica sp.n. are somewhat longer, its presutural dc bristles are strongly inclinate,its t

a-tp section is slightly longer than that of fittkaui, its acmi are more sparse than on fittkaui. The surstylus of T. tunisica sp. n. can be characterized by its comparatively short process and bristles. 1,0 mm Fig. 1: Thoracochaeta tunisica sp. n.
