ABSTRACT. New data on some Mediterranean dolichopodid species are discussed. The following re-combinations (from Hercostomus) are proposed in the paper (comb.n.): Ortochile morenae (Strobl, 1899), Sybistroma parvilamellata (Macquart, 1827), Sybistroma parvula (Parent, 1927), Sybistroma quadrifilata (Strobl, 1899) and Sybistroma quadrifilata (Becker, 1917, nec Strobl, 1899). Gymnopternus quadrifilatus Strobl, 1899 is removed from synonymy with Sybistroma parvilamellata and placed in synonymy to Sybistroma parvula (syn.n.). A new name Sybistroma theodori Grichanov et Nourti, nom.n., is proposed for Hercostomus quadrifilatus Becker, 1917 (nec Strobl, 1899). A neotype for Hercostomus quadrifilatus Becker is established. Updated keys to known species of Ortochile and Mediterranean species of Sybistroma are compiled. Sybistroma parvula and S. theodori are found in Morocco for the first time. Teuchophorus rifensis Nourti, Grichanov et Kettani, 2019 described from Morocco is found in earlier reports from Algeria and Krasnodar Territory of Russia under the name T. bipilosus Becker, 1908. The latter species is removed from faunas of Algeria and Russia.
