Abstract. Durand, P. - Ophrys aegirtica P. Delforge 1996 in the department of Tarn (81, France) [Natural. belges 80 (Orchid. 12) (1999): 230-232]. Described in november 1996, Ophrys aegirtica, a late flowering O. fuciflora s.l. with large flowers and own pollinator, was at first considered as an endemic of South-West of France: departments of Gers (32), Haute‑Garonne (31) and Hautes‑Pyrˇnˇes (65) and later discovered in the Riviera: department Var (83), and in the lower Rhone basin: departments Dr™me (26) and Vaucluse (84). Research in 1997 and 1998 in the department of Tarn (81) has revealed the presence of O. aegirtica, with 4 populations on the Causse de Labrugui¸re. The demonstration of the identity of those 4 populations with O. aegirtica is made.
