Our examinatton of types and other material of both S, rugosus and S. clavitopis (Fowler, 1938) has clarified that S. rugosits represents postlarvae and juveniles of the latter speeies. We therefore regard S, rugosus as a junior synonym of S, clavilapis and comment on its ontoge- netic changes in morphology, Key Words: Actinopterygii, Peristediidae, Satyrichthys rugosus, Satyrichtbys clavilapis, Acanthostedion, synonym. Introduction Fowler (1943), who described Acanthostedion with A, rugosum Fowler, 1943 from the Philippines as its type species, stated that the genus is charactertzed by having five dorsal-fin spines, a sticklike rostral projectien, and a well developed parietal spine. Since then, no other species has been included in Acanthostedion, and no additional specimens of A. rugosum have been collected. Miller (1967) noted that the description ef Acanthostedion was based on postlarvae and juveniles, and that the postlarvae of peristediids have a long rostral projection and a well devel- oped parietal spine. In addition, MMer (1967) pointed out that the holotype of A. ru- gosum is damaged and that three of the seven paratypes have seven dorsal-fin spines, not five; therefore, he treated Acanthostedion as a junior synonym of Satyrichtlrys Kaup, 1873 without discussing the validity of A. rugosum. Our com- parison reported here, among all species of Satyrichthys (sensu Kawai 2008), shows that S. rugosus is a junior synonym of S. clavilqpis (Fowler, 1938), a species knewn firom the Philippines, Indonesia, and the South China Sea (Fowler 1938; Richards 2000; Kawai and Takata 2008).

Results and Discussion The peristediid genus Satyrichthys was established as having a broad head and mesethmoid, postocular, parietal, and preopercular spines, with Peristethus rieffeti NII-Electronic Library Service JapaneseJapaneseSociety Society ofSystematicof Systematic Zoology 92 T. Kawai and Y. Takata Kaup, 1859 as the type species (Kaup 1873). Later, Kamohara (1952) characterized Salyrichtbys as being toothless with a strong preopercular spine. Since then, most authors have agreed with this latter definition (e.g., Miller 1974; Ochiai and Yatou 1984; Yamada 2002). Recently, Kawai (2008) analyzed peristediid interrelationships using morphological data, and demonstrated that'this concept of Satyrichtdys is not monophyletic. Consequently, he divided it into two genera, Satyrichtbys per se and Scalicus, and characterized this restricted Satyrichtdys by following character combinationi upper jaw teeth absent; lateral margin of head smooth; posterior parts of lower lateral rows of bony plates separated from each other; barbels on lower jaw not branched, except for posteriormost lip and chin barbels (some species without chin barbels); number of soft rays of dorsal fin fewer than 20; and number of seft rays of anal fin fewer than 19. He also suggested that Satyrichthys is separated from Scalicus in having low numbers of dorsal- and anal-fin soft rays (at most 19 dorsal and 18 anal vs at least 20 in both fins in Scalicus). The fo11owing 14 nominal species included in Peristediidae have all the charac- ters of Satyrichthys listed by Kawai (2008): S. adeni, S. clavilqpis, S, halei (Day, 1888), S, tsohawae, S. Iaticeps (Schlegel, 1852), S. Zingi, S, tongicops, S, magnus, S. moluccensis (Bleeker, 1851), S, piercei Fowler, 1938, S, pothumaluva (Deraniyagala, 1936), S. riqtr/eti, S. rugosus, and S. welchi. Day (1888) described S. hatei as a new species based on a single specimen with a poor description and no illustrations; furthermore, the whereabouts of the holotype are unknown (Eschmeyer 1998), MMer (1974) suggested that this species is a nomen dubium on account of the lack of an extant type and the inadequate description, and we agree with this. De Beau- fort and Briggs (1962) showed that S. Iaticqps is a junior synonym of S. motuccensis based on a comparison of the type specimens of both nominal species. Miller (1974) later also showed that S. piercei and S, pothumatuva are junior synonyms of S. adeni. Although Cemro and Lloris (1997) pointed out a purported synonymy be- tween S, moluccensis and S. welchi, the number of barbels is clearly different be- tween the two, i,e,, 3+O in S.

The aim of this studs, is to infer Telationships among the species in the family based on morpho- logical characters and to revise the genus-level classification en the basis of the inferred pattern of phylogeny. Twenty-four peristediid and 16 outgroup taxa, i.e., 13 triglid and three hoplichthyid species, were used for the phylo- genetic analysis. Monophyly, of the Peristediidae is highly corroborated and two major clades are recognized in the family. The first clade ineludes Gar- gariscus, Heminodus, Satyrichtbys, and Paraheminodus, and the second in- cludes only Peristedion. It beeame clear that the genus SatyrichthJ)s is a non- monophyletic group, In conclusion, six monophyletic genera are recogriized in the Peristediidae: Oargariscus, Hentinodus, Paraheminodus, Peristedion, Satyrichtltys, and Scalicus, Accordingly, I propose seven new combinations with Scalicus as follows: Scaticus engyceros, S. gilberti, S. hians, S. investiga- toris, S. orientalis, S, quadratorostratus, and S. serrutatus, Key Words: Teleostei, Scorpaeniformes, Peristediidae, phylogenetic sys- tematics. Introduction Armored sea robins, the family Peristediidae (sensu Nelson 2006), comprise about 36 benthic species that are currently classMed tn four or five genera (Miller 1974; Kawai et al, 2004a, 2004b; Nelson 2006).

Journal of Fisheries 8(2): 850–853. Abstract Barbels are sensory-appendage near the mouth of many fishes including Cyprinidae, Ictaluridae and Peristediidae and commonly used for identification of the species. Similarly scales and bony plates of fishes also being used in taxonomic studies. Satyrichthys laticeps commonly called armoured searobins, is a deep-sea peristediid that distributed in the Indo-West Pacific region of the world. However, surface structures of has been unknown. The aim of this study is to reveal the microstructures of barbels and bony plates of S. laticeps, occurring in the Andaman Sea of Thailand, for the first time by using a scanning electron microscopy method. The chin barbels were characterised by a pebble-like surface whereas lip barbels resemble wooden texture. Taste bud-like organs were only visible in chin barbels. Bony plates from heads contained small semispheres around spine. In dorsolateral of posterior body, pits appeared at the apices, and semispherical buds were present in the middle and basal parts of tubercles.

    The First Two Complete Mitochondrial Genomes for the Family Triglidae

    www.nature.com/scientificreports OPEN The first two complete mitochondrial genomes for the family Triglidae and implications Received: 20 January 2017 Accepted: 31 March 2017 for the higher phylogeny of Published: xx xx xxxx Scorpaeniformes Lei Cui1, Yuelei Dong1, Fenghua Liu1, Xingchen Gao2, Hua Zhang1, Li Li1, Jingyi Cen1 & Songhui Lu1 The mitochondrial genome (mitogenome) can provide useful information for analyzing phylogeny and molecular evolution. Scorpaeniformes is one of the most diverse teleostean orders and has great commercial importance. To develop mitogenome data for this important group, we determined the complete mitogenomes of two gurnards Chelidonichthys kumu and Lepidotrigla microptera of Triglidae within Scorpaeniformes for the first time. The mitogenomes are 16,495 bp long in C. kumu and 16,610 bp long in L. microptera. Both the mitogenomes contain 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes and two non-coding regions. All PCGs are initiated by ATG codons, except for the cytochrome coxidase subunit 1 (cox1) gene. All of the tRNA genes could be folded into typical cloverleaf secondary structures, with the exception of tRNASer(AGN) lacks a dihydrouracil (DHU) stem. The control regions are both 838 bp and contain several features common to Scorpaeniformes. The phylogenetic relationships of 33 fish mitogenomes using Bayesian Inference (BI) and Maximum Likelihood (ML) based on nucleotide and amino acid sequences of 13 PCGs indicated that the mitogenome sequences could be useful in resolving higher-level relationship of Scorpaeniformes. The results may provide more insight into the mitogenome evolution of teleostean species. Generally, the fish mitogenome is a circular and double-stranded molecule ranging from 15 to 19 kilobases in length.

The aim of this study is to infer relationships among the species in the family based on morpho- logical characters and to revise the genus-level classification on the basis of the inferred pattern of phylogeny. Twenty-four peristediid and 16 outgroup taxa, i.e., 13 triglid and three hoplichthyid species, were used for the phylo- genetic analysis. Monophyly of the Peristediidae is highly corroborated and two major clades are recognized in the family. The first clade includes Gar- gariscus, Heminodus, Satyrichthys, and Paraheminodus, and the second in- cludes only Peristedion. It became clear that the genus Satyrichthys is a non- monophyletic group. In conclusion, six monophyletic genera are recognized in the Peristediidae: Gargariscus, Heminodus, Paraheminodus, Peristedion, Satyrichthys, and Scalicus. Accordingly, I propose seven new combinations with Scalicus as follows: Scalicus engyceros, S. gilberti, S. hians, S. investiga- toris, S. orientalis, S. quadratorostratus, and S. serrulatus. Key Words: Teleostei, Scorpaeniformes, Peristediidae, phylogenetic sys- tematics. Introduction Armored sea robins, the family Peristediidae (sensu Nelson 2006), comprise about 36 benthic species that are currently classified in four or five genera (Miller 1974; Kawai et al.

A total of 496 species in 118 families are listed with collection records and/or taxonomic remarks. A new Japanese name was established for Diceratias trilobus. Key words: deep-water fi shes, fi sh fauna, distribution, Tohoku District Introduction The Tohoku (meaning northeast in Japanese) District is a northern part of Honshu Island, Japan. The Pacifi c side is washed by the cold Oyashio Current from the north and warm Kuro shio Current from the south, resulting in good fi shing grounds for a scomberesocid Cololabis saira, a gadid Gadus macrocephalus and several scorpaenids (e.g., Sebastolobus macrochir).
