“… 2019 ). The largest superfamily the order of Stomatopoda is Squilloidea, which is morphologically diverse and includes over 185 species in 49 genera (Ahyong 2001 , 2005 ; Van Der Wal and Ahyong 2017 ). As active predators in muddy and sandy substrates on coastal and continental shelf habitats (Abelló and Martin 1993 ; Ahyong 2005 ), some species of Squilloidea are also major fisheries targets, including Squilla mantis (Abelló and Martin 1993 ; Maynou et al.…”

“…Up to three sequences were selected to represent a species when several different sequences were available within a species (applied to 12 species in total) in which those sequences derived from the different studies were clustered for all 12 species; thus, the terminal branch of each species was compressed in the final tree (Figure 3, Supplementary Figure S1). Three species from the superfamily Parasquilloidea were selected as the outgroups because of their close relationship to Squilloidea (Van Der Wal et al, 2017, 2019. The analysis involved 67 nucleotide sequences from 46 species of mantis shrimp.…”

“…Mantis shrimps or stomatopods (Crustacea: Malacostraca) are predatory marine crustaceans, which are found mainly in tropical and subtropical coastal waters and are characterized by the remarkably developed second maxilliped that has been modified as a powerful raptorial appendage (Ahyong et al, 2008). Almost 500 species of stomatopods are known and divided into 17 families within seven superfamilies (Ahyong & Harling, 2000;Ahyong et al, 2008;Van Der Wal & Ahyong, 2017;Hwang et al, 2019;WoRMS, 2021). The life history of stomatopods involves a series of larval stages consisting of short propelagic and long pelagic phases.…”

Morphological observations and molecular confirmation of larvae ofLevisquilla inermis(Crustacea: Stomatopoda) from the Seto Inland Sea

Mantis shrimps are commercially important crustaceans in many areas of the world. In contrast to the relatively common studies of adults, limited studies have been attempted of larvae because of a lack of identification keys. The objectives of this study were two-fold: (1) to link wild-caught larval specimens from the Seto Inland Sea to a certain species and (2) to present a detailed morphological description of the last larval stage. The resulting molecular phylogenetic tree based on 16S rRNA gene sequences strongly implies that our larval specimens were linked to Levisquilla inermis, which was barcoded from a newly collected adult specimen with a morphological identification. K2P genetic divergence was found to be 0% among the larval and adult specimens. The congeneric species L. jurichi was the sister group of the L. inermis cluster, but the K2P distance between them was 3.4%, and it was considered a distinct species. Morphological observations provided five major distinguishing characteristics of the last-stage larva of L. inermis: (1) propodus of second maxilliped with three basal spines, (2) all five pleopods possessing an appendix interna with cincinnuli, (3) exopod of uropod longer than the endopod, (4) distal margin of the exopod of the uropod reaching the lateral tooth of telson, and (5) telson with nine intermediate denticles. Overall, our results reveal the importance of combining molecular and morphological analyses for solving stomatopod larval identification. This finding can be used to support and facilitate future research on the taxonomy and biodiversity of stomatopod larvae.

The mantis shrimp superfamily Squilloidea, with over 185 described species, is the largest superfamily in the crustacean order Stomatopoda. To date, phylogenetic relationships within this superfamily have been comprehensively analysed using morphological data, with six major generic groupings being recovered. Here, we infer the phylogeny of Squilloidea using a combined dataset comprising 75 somatic morphological characters and four molecular markers. Nodal support is low when the morphological and molecular datasets are analysed separately but improves substantially when combined in a total-evidence phylogenetic analysis. We obtain a well resolved and strongly supported phylogeny that is largely congruent with previous estimates except that the Anchisquilloides-group, rather than the Meiosquilla-group, is the earliest-branching lineage in Squilloidea. The splits among the Anchisquilloides- and Meiosquilla-groups are followed by those of the Clorida-, Harpiosquilla-, Squilla- and Oratosquilla-groups. Most of the generic groups are recovered as monophyletic, with the exception of the Squilla- and Oratosquilla-groups. However, many genera within the Oratosquilla-group are not recovered as monophyletic. Further exploration with more extensive molecular sampling will be needed to resolve relationships within the Oratosquilla-group and to investigate the adaptive radiation of squilloids. Overall, our results demonstrate the merit of combining morphological and molecular datasets for resolving phylogenetic relationships.
