Abstract
Recently, the first sightings of the semi-slug Vitrinobrachium breve have been reported in Belgium. However, this species was probably already present in the east of the country a century ago. We present a historical investigation starting from an illustration in a book by W. Adam on Belgian land molluscs published in 1960. The depicted shell was presented as that of the semi-slug Eucobresia diaphana (Draparnaud, 1805) and was collected in 1923 in Malmedy. We show it most certainly belongs to V. breve. We also discuss the halo-effect hypothesis of an authoritative work in long-term identification errors and the historical biogeographic implications for these two species.
期刊介绍:
The Journal of Conchology is the world''s oldest continuing publication on the subject. Published twice a year, it contains scientific papers and short communications on molluscs with emphasis on promoting conservation, biogeography and taxonomy. The contents cover, typically, descriptions of new species from anywhere in the world and reports concerning the ecology, distribution and status of molluscs. Both living and fossil molluscs are dealt with.
