Philinoglossa helgolandica

Hertling, 1932

P. helgolandica measures up to 3 mm in the length of the translucent greyish shell-less body. On the head is a pair of darker longitudinal bands. A kind of purple, veiny marking on each side of the head is described. A blackish renal gland is present at the rear. Small glandular structures can be seen through the skin and are especially characteristic.

It is a constituent of the meiofaunal community living in sublittoral shelly gravel.

Only a few records from the North Sea (Distr. P. helgolandica). Further distribution from Helgoland and the Mediterranean Sea (Banyuls-sur-Mer).
