. ?lapeta, M. commoda was firstly described by Van Baren et al. (2016) who just mentionned that this species was not recorded in high latitudes yet (beyond 60°North and South) The species was then revised by Simon et al. (2017), who described the distribution of this species as ubiquitous using available reference sequences. The high genetic variability within this newly described species was already highlighted in the literature, 48%) and Hawaii (OSD56, 57 around 25% and 144 10%

. Worden, Simon et al. proposed the hypothesis that speciation events should be ongoing inside M. commoda. The OSD dataset provided specific patterns for both M. commoda AB and C (Fig.5 and Fig. S2) suggesting that, these two clades are not ubiquitous (M. commoda was not recovered in Mediterranean Sea Fig, 5A) and that, M. commoda AB and C could be in fact different species. Interestingly, M. commoda AB OSD distribution particularly fitted the clade A strains distribution in ?lapeta et al, 2006.

. Hawaiisimon, in Mediterranean Sea off Egypt (OSD53 22%) and in Singapore (OSD95 12%). The OSD distribution agreed with previous data One representative strain was isolated in Mediterranean Sea in summer in, This clade was recorded at the 3 Hawaii stations (OSD56, 57 29%, 144 23%), in Florida (OSD37 31%), off Portugal (OSD101 30%)1109) and then, recovered from clone libraries in the Red Sea References, 1109.
