Résumé fourni par la source

Two new species belonging to the cosmopolitan subfamily Frieseinae are described from northeastern Iran. Friesea paraafurcata sp. nov. is characterized by a relatively small body size (up to 0.8 mm in length), absence of pigmentation in the eyes and body, a reduced number of ocelli (5–7 + 5–7), and complete reduction of the furca and retinaculum. The enigmatic genus Gisinea is recorded from Iran for the first time, and G. persica sp. nov. represents the fourth species of the genus described to date. Gisinea persica sp. nov. can be distinguished by the following combination of characters: absence of pigmentation in the eyes and body, reduced number of ocelli (6 + 6), labium with 5 + 5 chaetae, and furca with 4 + 4 chaetae.
