“…In this sense, to solve geographic morphological variation problems in the future, one possible approach is to sequence the DNA of the spent female crab (see Li et al ., 2019), which could also provide useful data for geographic comparisons. An alternative is to sequence the DNA barcode region of larvae collected at different geographic locations and examine their morphology, a methodology successfully applied to identify other marine organisms, such as fish and stomatopod larvae (Chu et al ., 2019; Wong et al ., 2021).…”

The complete larval development of the spider crab Maguimithrax spinosissimus (Lamarck, 1818) is re-described and illustrated in detail from laboratory-reared material. The development consisted of the typical pattern reported for the Majoidea, two zoeal stages and one megalopa. The complete larval development from hatching to first crab lasted 5–6 days at temperatures that ranged between 24–28 °C. Both zoeal stages of M. spinosissimus exhibited moderate reduction in the number of setae in the maxilla and maxillipeds, from the first to the second zoeal stage, when compared with other closely related species. Maguimithrax spinosissimus can be easily distinguished from other species belonging to the closely related genus Mithrax by the (i) setation of the endopod of the maxillule, maxilla and second maxilliped in both zoeal stages; (ii) setation of the scaphognathite of the maxilla in the first zoeal stage; (iii) setation of the basis of maxilliped I in the second zoeal stage and megalopa; (iv) morphology of the antennule and antenna in the second zoeal stage; and (v) setation of the antennule, coxal endite of maxilla, and exopod of second maxilliped in the megalopa. All these characters support the recent generic status of Maguimithrax within the Mithracidae. Additional morphological details, not available previously, are provided. This study will provide support for conservation strategies in this species.

“…The K2P distance of the nucleotide sequences of 16S rRNA and/ or COI genes have been proposed as one of the indicators for species identification of stomatopods (Tang et al, 2010;Wong et al, 2021). The distances to be found within the species are considered below 2-2.4% for the COI gene and below 0.91-2.1% for the 16S rRNA gene (Tang et al, 2010;Wong et al, 2021). The present study also demonstrates that the K2P distance of 16S rRNA gene can be considered 1% or lower within the species of Squilloidea.…”

“…The K2P genetic distances of the 16S rRNA gene were 1% or below within species (Supplementary Table S1) except for the distances in Alima orientalis and Oratosquilla oratoria (3.7% and 0.3-1.3%, respectively) in which the greater sequence divergences were indicated (Du et al, 2016;Cheng & Sha, 2017;Wong et al, 2021).…”

“…A DNA barcode is also useful to identify larvae collected from the field into species by matching with the available sequences from GenBank. Such methods have already been applied to crabs, barnacle larvae, fish larvae and stomatopods (Tang et al, 2010;Chen et al, 2013;Chu et al, 2019;Li et al, 2019;Wei et al, 2021;Wong et al, 2021). In addition, DNA barcoding as a method for identifying stomatopod larvae has been used not only for taxonomy (Barber & Erdmann, 2000;Feller et al, 2013) but also for experimental (Feller & Cronin, 2014;Feller et al, 2019) and diversity or distribution studies (Barber et al, 2002;Barber & Boyce, 2006;Tang et al, 2010;Abinawanto et al, 2019).…”

“…The larvae of the superfamily Squilloidea can be distinguished from those of the other superfamilies based on a flatter carapace and a slender abdomen (Ahyong et al, 2014). In Japan, 25 out of 70 recorded species are classified in the Squilloidea (Ahyong, 2012;Osawa & Fujita, 2016;Nakajima et al, 2020) and among them, late-stage larvae have been described in 12 squilloid species (Alikunhi, 1944(Alikunhi, , 1952(Alikunhi, , 1975Manning, 1962;Hamano & Matsuura, 1987;Zheng et al, 2006;Veena & Kaladharan, 2010;Wong et al, 2021). During our recent cruise in the Seto Inland Sea of Japan, late-stage larvae with a pair of large orange spots on the basal part of the fifth pleopods were found.…”

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

2021

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.

Pelagic larval stages play a critical role in the dynamics of marine populations since they are the main way of dispersal and habitat colonization. Here, we examined the larval dispersal pathways of two common stomatopod species in the western Atlantic: Squilla empusa and Lysiosquilla scabricauda. To complement this goal, we also analyzed the haline tolerance of the stomatopod larvae collected in an estuary from the southern Gulf of Mexico. Larval dispersal was simulated using a Lagrangian particle‐tracking module coupled to the Global HYCOM model and consisted of releasing 100 passive particles from each starting site. Results indicated a high level of larval retention in the west Florida shelf and over the narrow western shelf of the Gulf of Mexico. In the South Atlantic Bight, Central America, and northern South America the larval transport was almost unidirectional following the pattern of currents. Generally, connections were among nearby sites, but long‐distance transport can also occur when larvae are trapped by great high‐speed currents. Retention of larvae and connection with neighboring sites were due to local atmospheric and hydrological conditions. During fieldwork, we found two kinds of larvae: antizoea and alima. Morphological characteristics of the antizoea correspond to the superfamily Lysiosquilloidea, and those of the alima, with the superfamily Squilloidea. The antizoea larvae were found in salinity values as low as 21.9 psu, while the alima were at 23.2 psu. Salinity tolerances and dispersal potential of larvae indicate a high level of colonization of new habitats and a broad intrusion into the estuaries.
