“…In contrast, our results showed a highly supported clade of smashing taxa comprising members of the families Gonodactylidae, Takuidae, and Protosquillidae (Figures 3, 4 and S1). A clade of spearing taxa, Squilloidea, was recovered consistently as well supported in the nucleotide analyses (Figures 3A and 4), congruent with other studies [18,[33][34][35][36]. However, the various Eumalocostraca-rooted mixed amino acid nucleotide analyses recovered Squilloidea as a grade (Figures 3B and S1) and the position of Squilloides leptosquilla deserves further investigation.…”

“…As next-generation sequencing (NGS) technology, such as genome skimming (shallow, low pass sequencing), becomes more accessible, studies using whole mitochondrial genomes in their phylogenies have had better resolution and support compared to those of analyses with partial mitogenomic data [29][30][31][32]. To date, 15 complete mitogenomes of Stomatopoda have been published, though phylogenetic studies [33][34][35][36] have used only a proportion of these. The study by Yang et al [36] used the most, with 13 stomatopod mitogenomes and rooted their analysis with Penaeidae Rafinesque, 1815 [37] (Decapoda).…”

Stomatopoda, commonly known as mantis shrimps, are notable for their enlarged second maxillipeds encompassing the raptorial claw. The form of the claw can be used to divide them into two basic groups: smashers and spearers. Previous phylogenetic studies of Stomatopoda have focused on morphology or a few genes, though there have been whole mitochondrial genomes published for 15 members of Stomatopoda. However, the sampling has been somewhat limited with key taxa not included. Here, nine additional stomatopod mitochondrial genomes were generated and combined with the other available mitogenomes for a phylogenetic analysis. We used the 13 protein coding genes, as well as 12S rRNA, 16S rRNA genes, and included nuclear 18S rRNA gene sequences. Different rooting options were used for the analyses: (1) single and multiple outgroups from various eumalocostracan relatives and (2) a stomatopod-only dataset, with Hemisquilla californiensis used to root the topologies, based on the current hypothesis that Hemisquilla is the sister group to the rest of Stomatopoda. The eumalocostracan-rooted analyses all showed H. californiensis nested within Stomatopoda, raising doubts as to previous hypotheses as to its placement. Allowing for the rooting difference, the H. californiensis outgroup datasets had the same tree topology as the eumalocostracan outgroup datasets with slight variation at poorly supported nodes. Of the major taxonomic groupings sampled to date, Squilloidea was generally found to be monophyletic while Gonodactyloidea was not. The position of H. californiensis was found inside its superfamily, Gonodactyloidea, and grouped in a weakly supported clade containing Odontodactylus havanensis and Lysiosquillina maculata for the eumalocostracan-rooted datasets. An ancestral state reconstruction was performed on the raptorial claw form and provides support that spearing is the ancestral state for extant Stomatopoda, with smashing evolving subsequently one or more times.

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.
