What’s in a name? A worm by any other name must surely be as tasty! Inconsistent use of common and species names of bait polychaete worms can affect management C.A.

Gunnarea gaimardi • Two distinct lineages Two species? Lumbrineris tetraura Lysidice natalensis • Scenario 1 Species from SA ≠ species from China • Species from SA ≠ species from 2 species in SA India • Scenario 2 1 widespread species that includes 4 others Conclusions • Inconsistent use of common and species names creates loopholes and confusion Develop identification guide, using easy to see characteristics, to be distributed with bait collecting permits • Further studies with additional markers needed to resolve taxonomy of Marphysa corallina, Lumbrineris tetraura & Gunnarea gaimardi Thank You • Organisers of FBIP Forum • Bait collectors • Research partners • Funders Thank you: Students .
