von Arx (1971) introduced the family Testudinaceae to include the genera Testudina (type), Neotestudina, Lepidosphaeria, Argynna (later transferred to Argynnaceae) and Pseudophaeotrichum (synonymized as Neotestudina). Testudinaceae is characterized by astomatous ascomata with a dark peridium, bitunicate asci and dark, 1-septate ascospores (about 10 μm long) (Phookamsak et al. 2015, Wanasinghe et al. 2017). Hawksworth & Booth (1974) synonymized Testudinaceae under Zopfiaceae. Subsequently, Hawksworth (1979), considered Zopfiaceae as a synonym of Testudinaceae on the basis of the size and more especially the shape and type of sculpturing of the ascospores in SEM studies. Eriksson (1981) accepted both families and Zopfiaceae was validated by Eriksson & Hawksworth (1992). Hyde et al. (2013) considered Testudinaceae as a family in Dothediomycetes and included five genera: Lepidosphaeria, Neotestudina, Testudina, Ulospora and Verruculina (Suetrong et al. 2009).

Currently, Testudinaceae includes the genera Angustospora, Lepidosphaeria, Lojkania, Muritestudina, Neotestudina, Testudina, Ulospora and Verruculina (Hyde et al. 2013, Wanasinghe et al. 2017). This paper introduces a novel genus Halotestudina and a novel species to the family Testudinaceae which was collected from mangrove habitats.

Type species: Testudina Bizz., Atti Inst. Veneto Sci. lett., ed Arti, Sér. 6 3: 303 (1885).
