The occurrence of eight species of Bibionidae is reported from Sardinia, mainly based upon recent collections made in the south-western part of the island. Two species, Dilophus bispinosus Lundström, 1913 and D. humeralis Zetterstedt, 1850, are new records for Sardinia, while two species are described as new to science: Bibio sardocyrneus sp. nov. (from Sardinia and Corsica) and Dilophus sardou...

Elachista sulcsiella sp. n. from Latvia is described. A series of specimens was collected by netting and breeding in three localities. The newly described species belongs to the Elachista bifasciella-group and is likely a close relative of E. irenae Buszko and E. talgarella Kaila. The adult habitus and genitalia of both sexes are figured.

A floristic survey of the marine algal biodiversity Antsiranana Bay, northern Madagascar, was conducted during November 2018. This represents first inventory encompassing three major macroalgal classes (Phaeophyceae, Florideophyceae and Ulvophyceae) for little-known Malagasy flora. Combining morphological DNA-based approaches, we report from our collection a total 110 species including 30 Phaeo...

Density, biomass and productivity of animals >0.5 mm were estimated in 4 shallow subtidal rocky reef habitats in temperate northeastern New Zealand. The main objective was to determine the relative contributions of mobile epifauna (0 5-10 mm) and megafauna (> 10 mm) to the flux of materials on the reef. The habitats surveyed were (1) Carpophyllum plumosuln var. capillifolium forest (Phaeophycea...

Genetic variation in tolerance for seaweed chemical defenses among populations of marine herbivores is poorly described, either because few marine studies have addressed the issue or because the feeding preferences of populations of marine herbivores rarely differentiate. We address this using the polyphagous amphipod Ampithoe longimana (Crustacea), which commonly consumes, and lives on, terpen...
