Krynickillus maculatus Kaleniczenko, 1851 Limax ecarinatus O. Boettger, 1881 Limax grossui Lupu, 1970 Limax maculatus (Kaleniczenko, 1851) Limax pseudoflavus Evans, 1978[1] Limacus maculatus, the green cellar slug or Irish yellow slug, is a species of slug native to the Caucasus and Black Sea coast.

[2] It has also been introduced to a number of northern European countries.

It is most likely to be confused with Limacus flavus, which it closely resembles externally.

[3] The reason is that Nunneley already described a Limax maculatus in 1837; this turned out to be a synonym of Limax maximus, but nevertheless the combination Limax maculatus cannot be re-applied to a species described under the name maculatus at a later date (even though that 1851 description used a different genus, Krynickillus).

This species is believed to be native in parts of Romania, Bulgaria, Ukraine, Turkey, southwestern Russia, Armenia, Azerbaijan, and Georgia.
