Comparisons with previous studies of the first zoeal stages in the Xanthidae from Korean waters, revealed that some former studies were incorrected. The first zoea of M. orientalis described by Ko was identical to the first zoea of Macromedaeus distinguendus described by Terada. In addition, zoeal stages of Nanocassiope granullipes described by Ko & Clark was revealed the zoeal stages of M. cassiopes. So, the first zoea of M. orientalis is redescribed and illustrated in detailed with color photo herein, and compare its morphological characteristics with previous described zoea of N. granulipes by Ko & Clark Keywords: redescription, first zoea, Xanthidae, Microcassiope orientralis, Nanocassiope granulipes 1. INTRODUCTION Currently, five species of the genus Microcassiope are recognized in the subfamily Xanthinae in the family Xanthidae [1]: Microcassiope granulimana, M. minor, M. orientalis, M. taboguillensis, and M. xantusii. Among them, two species (M. minor by Clark et al. [2], and M. orientalis by Ko, [3]) of the first zoea stages (M. minor by Clark et al. [2], and M. orientalis by Ko, [3]) in this genus have been recorded from the world. The only one species, M. orinetalis, has been recorded from Korea ([4]; [5]). During continuous comparisons with previous studies of the first zoea in the family Xanthidae from Korean waters. Some previous studies were revealed to be incorrected. The first zoea of M. orientalis described by Ko [3] was identical to the first zoea of Macromedaeus distinguendus described by Terada. In addition, zoeal stages of Nanocassiope granullipes described by Ko & Clark [6] was revealed the zoeal stages of M. cassiopes. Therefore, the purpose of this study is to re-describe and illustrate its first zoea with digital color photo, and compare its morphological characteristics with previous described zoea of N. granulipes by Ko & Clark [6]. 2. MATERIALS AND METHODS An ovigerous female Microcassiope orientalis was collected by SCUBA diving in about 20m depths from Geomun Island, Yeosu, Jeollanamdo, Korea on 1 August 2010. Female crab was reared in a glass beaker of 2,000 ㎖ at a constant seawater temperature of 22±1 ℃ and were fed on Artemia nauplii until zoeas hatched. The first zoeas were hatched on 9 August 2010 in the laboratory. The first zoeas were preserved in 95% ethyl Manuscript received: April 18, 2020/ revised: May 06, 2020/Accepted: May 12, 2020 Corresponding Author:[email protected] Tel:+82-51-999-6931, Fax: +82-51-999-5471 (Full Time) Lecturer, Dept. of Life Sciences, Silla Univ., Korea 278 International Journal of Advanced Culture Technology Vol.8 No.2 277-282 (2020) alcohol for examination. Living zoeas were taken digital photograph with a Leica EZ40 microscope and then processed in Photoshop. Zoeal specimens were dissected using the Leitz zoom stereomicroscope and appendages were examined under a Leitz Laborlux S microscope. Appendages were mounted in ethylene glycol and drawings were made with the camera lucida. Observations of setal counts on appendages and measurements were based on the mean of 10 specimens. The sequence of the zoeal description follows that of Clark et al. [7]. The long plumose natatory setae of the first and second maxillipeds were drawn truncated. The chromatophore patterns were observed with living zoeas. A micrometer was used for the zoeal measurements: Carapace length (CL) from the base of the rostrum to the most posterior carapace margin and rostral and dorsal spine length (RDL) from the tip of rostral carapace spine to the tip of the dorsal carapace spine. Specimens examined in present study and spent female were deposited in Silla University, Korea. Fig. 1. Color photos of adult and the first zoea of Microcassiope orientalis.

First maxilliped (Fig. 2G): Coxal segment with 1 seta; basis with 10 setae, arranged 2+2+3+3; endopod 5- segmented, with 3, 2, 1, 2, 5 (1 subteminal, 4 terminal) setae; exopod 2-segmented, distal segment with 4 long terminal plumose natatory setae. Second maxilliped (Fig. 2H): Coxa without seta; basis with 4 setae, arranged 1+1+1+1; endopod 3- segmented, with 1, 1, 5 (2 subterminal, 3 terminal) setae; exopod 2-segmented, distal segment with 4 long terminal plumose natatory setae. Abdomen (Fig. 2I): With 5 somites; somite 2 with 1 pair of lateral processes directed anteriorly; somite 3 with 1 pair of lateral processes directed posteriorly; somites 2-5 each with 1 pair of posterodorsal setae, respectively; somites 3-5 each with 1 pair of posterolateral spines, respectively; pleopod absent. Telson (Fig. 2I’): Each fork long, naked, with 1 stout lateral spine, 1 simple lateral seta and 1 stout dorsomedial spine; posterior margin with 3 pairs of setae. 4. DISCUSSION The first zoea of M. orientalis is identical to other the first zoeas of superfamily Xanthoidea suggested by Ko & Lee [8] as follows: well developed rostral and dorsal carapace spines and short lateral carapace spine; antennal exopod less than one third of protopod with one to three spines; endopods of maxillule and maxilla with 1, 2+4 setae, and 3+2+3 (rarely 2) setae, respectively; lateral processes on abdominal somites 2, 3; and fork of telson has on lateral seta, one lateral and dorsomedial spines. Morphological characteristics of the first zoea M. orientalis agree well with those of Nanocassiope granulipes (Rathbun, 1939) described by Ko & Clark [6] (Table 1), except in number of aesthetasc and seta on antennule and length of antennal exopod (Fig. 3). The difference in the antennule may be insignificant because a seta is sometimes confused as a minute aesthetasc under a microscope. The difference in the exopod/protopod ratio of antenna (8% in present study vs. 12% in Ko & Clark [6]) is due to measurement whether a terminal seta is included or not when measuring the length of antennal exopod. Hence, re-examined a spent female crab of N. granulipes used by Ko and Clark [6] to confirm species and identified as M. orientalis having defined carapace regions except fused mesogastric and posterogastric regions and a subdistal spine on a dactylus of the ambulatory leg (Lee & Ko [4]). Therefore, re-description of the zoeal stage of N. granulipes should be needed. Redescription of the First Zoea of Microcassiope orientalis (Crustacea: Decapoda: Xanthidae) 281 Table 1.

  • Deepwater Xanthid Crabs from French Polynesia (Crustacea, Decapoda, Xanthoidea)
    Bull. Mus. natl. Hist, nat., Paris, 4' ser., 14, 1992, section A, n° 2 : 501-561. Deepwater Xanthid crabs from French Polynesia (Crustacea, Decapoda, Xanthoidea) by Peter J. F. DAVIE Abstract. — A collection of brachyuran crabs of the family Xanthidae, trapped in deepwater in French Polynesia, has been studied. Of a total of 13 species, 10 are described as new, and four new genera are erected : Alainodaeus gen. nov. to include A. akiaki sp. nov. and A. rimatara sp. nov.; Epistocavea gen. nov. to include E. mururoa sp. nov.; Meriola gen. nov. to include M. rufomaculata sp. nov.; and Rata gen. nov. to include R. tuamotense sp. nov. Five species are described in existing genera : Banareia fatuhiva sp. nov.; Euryozius danielae sp. nov.; Medaeus grandis sp. nov.; Meractaea tafai sp. nov.; and Paraxanthodes polynesiensis sp. nov. The records of Demania garthi Guinot and Richer de Forges, 1981, Demania mortenseni (Odhner, 1925), and Lophozozymus bertonciniae Guinot and Richer de Forges, 1981, all represent considerable eastwardly range extensions. Actaea mortenseni Odhner, 1925, removed from Actaea by GUINOT (1976) and subsequently incertae sedis is re-described and placed into Demania for the first time.

FELDER1 1Department of Biology and Laboratory for Crustacean Research, University of Louisiana at Lafayette, Lafayette, LA 70504, USA 2Muséum national d’Histoire naturelle, Département milieux et peuplements aquatiques, 61 rue Buffon, Paris 75005, France Received 11 June 2013; revised 16 September 2013; accepted for publication 23 September 2013 Members of the brachyuran crab superfamily Xanthoidea sensu Ng, Guinot & Davie (2008) are a morphologically and ecologically diverse assemblage encompassing more than 780 nominal species. On the basis of morphology, Xanthoidea is presently regarded to represent three families: Xanthidae, Pseudorhombilidae, and Panopeidae. However, few studies have examined this superfamily using modern phylogenetic methods, despite the ecological and economic importance of this large, poorly understood group. In this study we examine phylogenetic relation- ships within the superfamily Xanthoidea using three mitochondrial markers, 12S rRNA, 16S rRNA, and cytochrome oxidase I (COI), and three nuclear markers, 18S rRNA, enolase (ENO) and histone H3 (H3). Bayesian and maximum-likelihood analyses indicate that the superfamily Xanthoidea is monophyletic; however, the families Xanthidae, Panopeidae, and Pseudorhombilidae, as defined by Ng et al., are not, and their representative memberships must be redefined. To this end, some relevant morphological characters are discussed. © 2013 The Linnean Society of London, Zoological Journal of the Linnean Society, 2014, 170, 86–109. doi: 10.1111/zoj.12093 ADDITIONAL KEYWORDS: COI – enolase – histone H3 – Panopeidae – phylogenetics – Pseudorhombilidae – 16S–12S–18S – Xanthidae.

Corrected 11-II-2008. Accepted 11-VI-2008. Abstract: A summary of the available information on stomatopod and decapod diversity of Isla del Coco and records of recently collected species during the CIMAR-MarViva expedition (January 2007) as well as the pres- ence of yet unpublished specimens deposited in the Museo de Zoología, Universidad de Costa Rica, is reported. The material of the CIMAR-MarViva expedition comprised 23 species, including nine species new for the island. Revision of the collection of the Museo de Zoología, including two unpublished records, revealed the presence of additional 12 decapod species not previously reported for the island. Overall, a total of 135 species (6 stomatopods and 129 decapods) has been reported so far for the island, which harbors 29.5% of all decapod species known to occur along the Pacific mainland of Costa Rica, and 16.3% of all decapods reported for the Panamic Province. The most diverse families (including > 10 spp.) at Isla del Coco are Xanthidae (14 spp.), Majidae and Alpheidae (each 11 spp.), and Porcellanidae (10 spp.). There is a strong affinity of the stomatopod and decapod fauna of both Isla del Coco and Islas Galápagos.

The decapod crustaceans of Madeira Island – an annotated checklist (Crustacea, Decapoda). Spixiana 38 (2): 205-218. We list 215 species of decapod crustaceans from the Madeira archipelago, 14 of them being new records, namely Hymenopenaeus chacei Crosnier & Forest, 1969, Stylodactylus serratus A.
