“…A recent morphology-based review of the family (Bolstad 2010) raised the number of known species from the 12-14 accepted by most previous studies (e.g., Nesis 1987;Kubodera et al 1998) to 25, making it one of the more diverse oegopsid families. Seven genera were recognised in the review, ranging from monotypic (Ancistroteuthis Gray, 1849;Filippovia Bolstad, 2010) to quite speciose (seven to ten species in Onychoteuthis Lichtenstein, 1818, andOnykia Lesueur, 1821) with the remaining genera each containing two or three known species ('Callimachus' [= Walvisteuthis Nesis and Nikitina, 1986; see Vecchione et al 2015]; Kondakovia Filippova, 1972;Notonykia Nesis, Roeleveld and Nikitina, 1998). As most of the examined material had been fixed in formalin, a molecular component was not possible at the time.…”

The oegopsid squid family Onychoteuthidae was recently revised based on morphology, but sufficient material for a complementary molecular analysis has not been available until now. In the present study, over 250 sequences of cytochrome c oxidase subunit I (COI) and 16S rRNA for 222 individuals were analysed to create a combined phylogeny for the family. Results support monophyly for the family and all seven onychoteuthid genera (including Moroteuthopsis, established herein as the senior genus name for species formerly attributed to Kondakovia); 29 genetically distinct species were recovered, with the BIN (Barcode Index Number) analysis for COI showing good congruence overall with morphological species groupings. No sequences were available for five additional known species, making the total family diversity likely to exceed 34 species. Seven of the BINs formed in this study appear to represent undescribed taxa, suggesting that even in this relatively well-studied family, much additional work remains before a comprehensive understanding of the diversity and evolutionary relationships for the Onychoteuthidae can be achieved.
