Sea Slugs of Portugal's Boletim

Following the recent publication of a paper combining analysis of chromatic variations and molecular data, a new species of the genus Polycera was described and it turns out to be one of the most common in Portugal. Although Polycera faeroensis is confirmed to be present, the newly described species Polycera kernowensis is the most often found.

Less than a week after the last addition, here's another new entry: the elusive Corambe testudinaria.

Although it had been previously recorded in Spain, in Galicia and in Western Andalusia, and was expected to occur in Portugal there were still no published records to confirm its presence. The small size and remarkable camouflage make it particularly difficult to spot so it's likely to have been missed up until now.
