Dirina arabica is a species of saxicolous (rock-dwelling), crustose lichen in the family Roccellaceae.[1] Found in Socotra, it was formally described as a new species in 2013 by lichenologists Anders Tehler and Damien Ernst. The type specimen was collected by the first author near the village in Homill, at an altitude of Шаблон:Convert. The species epithet refers to Arabia, the geographical location encompassing the type locality. The lichen is endemic to Socotra, where it grows on Eocene limestone rocks. It has a creamy-white, slightly Шаблон:Lichengloss thallus that is 0.1–0.5 mm thick and a chalk-like medulla. There are no soralia on the thallus. The ascomata have a circular outline and measure up to 2.0 mm in diameter, and have a pruinose, white-grey Шаблон:Lichengloss with a Шаблон:Lichengloss. Dirina arabica is a sister species to Dirina immersa, a sympatric species that can be distinguished from the former by its Шаблон:Lichengloss ascomata.[2]
