A new species of Streblospio (Polychaeta: Spionidae) from the northern Adriatic Sea (Mediterranean Sea)

“…Streblospio eridani n. sp. is easily distinguished from the description of S. eunateae (Martínez & Adarraga 2019) by its smaller size (4.7 -14.9 mm, compared to 10 -25 mm in S. eunateae), and the staining pattern with methyl green, in that the latter species shows uniform staining thoroughout the body, rather than a defined pattern (as in the new species herein described). Streblospio eridani n. sp.…”

“…To date, five species and one subspecies of the genus Streblospio are known: Streblospio benedicti Webster, 1879 originally described from northeast U.S.A.
