RESUMEN
The European species of the potter wasp genus Eumenes Latreille, 1802 (Vespidae, Eumeninae) are illustrated and a new illustrated key to the 13 recognised species is presented. Eumenesmediterraneusaemilianus Guiglia, 1951 is synonymised with E.papillarius (Christ, 1791) (syn. nov.), E.obscurus André, 1884 and E.andrei Dalla Torre, 1894 with E.pedunculatus (Panzer, 1799) (syn. nov.) and E.crimensis Blüthgen, 1938 with E.sareptanus André, 1884 (syn. nov.).
RESUMEN
The genus Psilota Meigen, 1822 is recorded for the first time from China, and the species Psilota bashanensis Huo and Zhao sp. nov. is described and illustrated based on the adult male. The complete cytochrome c oxidase subunit I (COI) gene of this new species has been successfully obtained and compared to that of other congeneric species. An updated key to adult males of the genus Psilota from the Palaearctic Region is also provided.

Abstract Eumerus Meigen, 1823 is a very speciose genus of flower flies from the Eastern Hemisphere. Several reports of introduced species of this genus in the Americas have been recorded since early in the twentieth century, with a present list of six species recorded to date from the Americas and the US territory of Hawaii. In this paper we give new geographical records for the African-native species Eumerus obliquus (Fabricius, 1805), which reflect the expansion of this fly through Brazil and Paraguay along the last twenty years. At the same time, we report a second species from Paraguay, Eumerus aurifrons (Wiedemann, 1824), being this the first Western Hemisphere record for this Asian-native species. We finally provide an identification key to all of the species of Eumerus presently known from the Americas and Hawaii.

In this paper 4 species of bat ectoparasites are recorded from the island of Sint Eustatius, Dutch Caribbean. One species of true bug (Hemiptera: Polyctenidae) as well as 3 species of bat flies (Diptera: Hippoboscidae: Streblinae) are recorded. All species are photographed. The first DNA barcodes for 3 bat ectoparasite species ( Trichobius frequens, Trichobius intermedius, and Hesperoctenes fumarius) have been posted to the BOLD database; DNA barcode sequences for a fourth species ( Megistopoda aranea) are the first from a Caribbean island.

The status of Tolmerus atricapillus calceatus (Meigen) is discussed. Based on morphological, ecological as well as genetic information it is concluded that Tolmerus calceatus stat. rev. should be treated as a valid species separate from T. atricapillus (Fallén). Characters to separate both are provided as well as a key to all Tolmerus species of northwestern Europe.
