A taxonomic revision of the Neotropical genus (Annonaceae), including five new species.

We present a taxonomic revision of , a genus of Neotropical Annonaceae occurring in lowland to premontane wet forest, mostly in areas surrounding the Andean mountain chain. We recognise 34 species, describing five as new here: from east of the Andes, Pirie & Chatrou, and Pirie & Maas, , endemic to Peru; Pirie, , from southern Peru and adjacent Bolivia and Brazil; and Pirie & Chatrou, , at higher elevations in northern Peru and Ecuador; and from west of the Andes, Pirie & Chatrou, endemic to Costa Rica, the most northerly distributed species of the genus. We provide an identification key, document diagnostic characters and distributions and provide illustrations and extensive lists of specimens, also presenting the latter in the form of mapping data with embedded links to images available online.

Unravelling the moons: review of the genera and in the Indo-Pacific (Demospongiae, Tetractinellida, Tetillidae).

(Selenka, 1867) and (Carter, 1886) occur in a broad range of marine environments and are allegedly widely distributed species in the Indo-Pacific. We coin the term 'moon sponges' for these species as they are spherical in shape with numerous porocalices resembling the lunar surface. Both species have a complex taxonomic history with high synonymization, in particular by Burton (1934, 1959).
