As a result of recent fieldwork in southern Portugal and Spain we report here an update on the distribution range and habitat preferences of T. mariae. The distribution of this species is mostly restricted to the coast of central Algarve (Portugal) and Huelva province (Spain), being heavily fragmented and discontinuous. The species appears to be habitat-specific, with a clear preference for habitat with stone pine and at a close distance from the sea. The conservation of T. mariae populations is threatened, particularly in Algarve, by anthropogenic changes in land use and habitat loss and by interspecific competition with its sibling and wider distributed T. argentata. We advocate that T. mariae should be considered as an endangered species and should be subjected to annual monitoring.
