| Cylisticus convexus, a rare synanthropic woodlouse in The Netherlands (Crustacea: Isopoda: Cylisticidae) Until recently, the occurrence of Cylisticus convexus (De Geer, 1778) in the Netherlands was uncertain. The only certain old record dates from March 1927, when the species was collected at the coal-shed of the Zoological Museum at Amsterdam. During the last years, two specimens have been collected on semi-natural sites. Both were found on a dike, one near Everdingen, in the province of Gelderland, and one near Ritthem, in the province of Zeeland. These are the first records of C. convexus in the field. Yet the species certainly is very rare in The Netherlands. The most important morphological characteristics of the species are described and... |

| Eluma purpurascens, new for the Dutch fauna (Crustacea: Isopoda: Oniscoidea). The first Dutch specimen of Eluma purpurascens was found on 29 April 1994 on the Kaloot, east of Vlissingen, in the south-western province of Zeeland. One year later the species proved to be locally common along the southern coast of the Oosterschelde and three years later several hundreds mature and immature specimens were found along the southern coast of the Westerschelde and along the coast of the North Sea. So far, the species has not been found on the isle of Schouwen-Duiveland. It seems to be almost absent inland although not all sites where this species might occur have yet been visited. In this paper the morphology of Eluma purpurascens is illustrated, and some notes on... |
