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%.

FIGURE 27. Phylogenetic hypotheses of the families Thyroscyphidae (A) and Sertularellidae (B) based on the 16S rRNA region. Numbers at nodes represent BPP and MLBS, respectively. N.B.: According to Galea et al. (2017: 263) and Galea & Schuchert (2019: 2), Sertularella sanmatiasensis El Beshbeeshy, 2011 FN424141 should be correctly regarded as S. antarctica Hartlaub, 1901.
