[Mammalogy • 2019] Parahypsugo happoldorum • A New Genus and Species of Vesper Bat (Chiroptera: Vespertilionidae) from West Africa, with Notes on Hypsugo, Neoromicia, and Pipistrellus

Abstract
We describe a new species of vespertilionid bat from Guinea and Liberia, West Africa. In this context we evaluate previously described taxa from West Africa assigned to Pipistrellus, Neoromicia, and Hypsugo. Based on genetics, morphology and ecology we conclude that the taxon Pipistrellus eisentrauti bellieri should be elevated to species level, and that the taxa bellieri, crassulus, eisentrauti plus the new species form a monophyletic clade for which a new genus name is proposed. The new genus occurs in forested regions south of the Sahara from Senegal to Ethiopia and Somalia, from where further taxa remain to be described.

[Ichthyology • 2015] Diplecogaster tonstricula • A New Species of Cleaning Clingfish (Teleostei: Gobiesocidae) from the Canary Islands and Senegal, eastern Atlantic Ocean, with a review of the Diplecogaster-ctenocrypta species-group

Eastern Atlantic Cleaner Clingfish

Abstract
The Diplecogaster-ctenocrypta species-group is reviewed; it comprises two species. The clingfish Diplecogaster ctenocrypta from the Canary Islands is redescribed. The new species Diplecogaster tonstricula, a facultative cleaner of other teleosts, is described on the basis of eight specimens and colour photos from Senegal and the Canary Islands, eastern Atlantic Ocean. The species is small, apparently not exceeding 23 mm total length; it is characterised by having nine dorsal-fin rays, eight anal-fin rays, 24–25 pectoral-fin rays, 14–15 principal caudal-fin rays, 13–16 rakers on third gill arch, pelvic disc without lateral papillae in region A, disc region B with two rows of weak papillae, interorbital distance 4.1–4.6 in head length, distance between disc and anus 14–17% of SL, head and body with 10–13 narrow vertical brownish bars, cheek with a white ocellus surrounded by black, and with a small black spot in the middle. The new species is compared with other species of the genus; a key to the six known species of the eastern Atlantic, Mediterranean and Black Sea and South African genus Diplecogaster is presented. A checklist is provided for the species of Diplecogaster and their synonyms.
