accurate assignment of cryptic larvae to species-level is a key aspect
of marine ecological research and can be achieved through integrated
molecular and morphological studies. A combination of two mitochondrial
markers (COI and 16S) and a
detailed morphological analysis was used to identify phyllosoma larvae
of slipper lobster (Scyllaridae) species collected during a survey in
the SW Indian Ocean. Two morphotypes were tentatively assigned to Acantharctus ornatus and Biarctus pumilus,
both genera for which the larval morphology was unknown. Morphological
revision of an adult specimen used to generate the putative A. ornatus sequences in GenBank
revealed that it was misidentified and corresponds to B. dubius. The final phyllosoma
stage of B. pumilus and
subfinal and final stages of A.
were described, clarifying prior misidentifications in the literature.
Scyllarid biodiversity in the SW Indian Ocean is underestimated and
sampling of deeper water layers is recommended to complete current
knowledge of species and larval stages present in the region.
