Description

'With regard to Pennaria disticha, we analyzed new sequences from Thuwal (Saudi Arabia, Red Sea), Sint Eustatius (the Netherlands, Caribbean), Bocas del Toro (Panama, Caribbean Sea), Bergeggi (Italy, Mediterranean Sea), Tricase (Italy, Mediterranean Sea), Dibba Al-Fujairah (United Arab Emirates, Gulf of Oman), and Galveston (Texas, Gulf of Mexico). We confirm the presence of several clades and putative cryptic species that indicates multiple invasive episodes and undercover a new clade from the Gulf of Oman. Finally, species delimitation analyses recover 2 to 3 clades as separate species within P. disticha, and 7 to 9 species withinTurritopsis, with T. lata being a complex of 2-4 cryptic species (Miglietta et al. 2019).
