Leptothecata: Sertularellidae

Genetic data (16S rRNA region) for Sertularella decipiens Billard, 1919 and S. quadridens (Bale, 1884) are provided for the first time, whereas the sequence of S. diaphana (Allman, 1885) appears to be slightly divergent from that of a specimen from the Philippines (Fig. 27B), with an intra-specific genetic distance of 2.7%.
