Limax grossui Lupu 1970,a slug new to the British Isles

Limax grossui Lupu, originally described from Bucharest, is recorded from Ireland where it is widespread. It closely resembles L. flavus externally and in having lemon-shaped eggs, but is larger, has rougher tubercles, deeper pigment, an overall green appearance and a more marked pattern of colour blotches on thc body and mantle. Internally the spermatheca duct is inserted near the base of the short, broad c-shaped penis in L. grossui. L. flavus has a long s-shaped penis and the spermatheca duct inserted on the oviduct. The intestinal appendix does not extend as far into the tail in L. grossui as it does in L. flavus.
L. grossui lives under logs and stones in woodland, while L.flavus occurs near human settlement, particularly in crevices of old walls and cellars.
