The total length of C. curvicornis mitogenome is 16,406 bp, which consists of 13 protein–coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region. It has the typical vertebrate mitochondrial gene arrangement. This is the first report of a complete mitochondrial genome in the fish suborder Callionymoidei.

Acta Ichthyol. Piscat. 47 (2): 163–171. Background. The reticulated dragonet, Callionymus reticulatus, was originally described based on a single specimen, the holotype from Malaga, Spain, south-western Mediterranean, probably collected before 1831. The holotype is now disintegrated; the specific characteristics are no longer discernible. The species was subsequently recorded from several north-eastern Atlantic localities (Western Sahara to central Norway), but missing in the Mediterranean. Material and methods. Specimens of C. reticulatus were observed and collected during two cruises in 2014 and 2016 in the Balearic Islands off Mallorca and Menorca. The collected specimens (8 females) have been deposited in the collection of the Hebrew University of Jerusalem (HUJ). All individuals of C. reticulatus were collected from beam trawl samples carried out during the DRAGONSAL0914 in September 2014, and during the MEDITS_ES05_16 bottom trawl survey in June 2016, on shelf and slope bottoms around the Balearic Islands. Both surveys used a ‘Jennings’ beam trawl to sample the epi-benthic communities, which was the main objective of the DRAGONSAL0914 and a complementary objective in the MEDITS_ES05_16. The ‘Jennings’ beam trawl has a 2 m horizontal opening, 0.5 m vertical opening and a 5 mm diamond mesh in the codend.

  • Systematic List of the Romanian Vertebrate Fauna

Compiling different bibliographical sources, a total of 732 taxa of specific and subspecific order remained. It is about the six large vertebrate classes of Romanian fauna. The first class (Cyclostomata) is represented by only four species, and Pisces (here considered super-class) – by 184 taxa. The rest of 544 taxa belong to Tetrapoda super-class which includes the other four vertebrate classes: Amphibia (20 taxa); Reptilia (31); Aves (382) and Mammalia (110 taxa). Résumé. Cette contribution à la systématique des vertébrés de Roumanie s’adresse à tous ceux qui sont intéressés par la zoologie en général et par la classification de ce groupe en spécial. Elle représente le début d’une thème de confrontation des opinions des spécialistes du domaine, ayant pour but final d’offrir aux élèves, aux étudiants, aux professeurs de biologie ainsi qu’à tous ceux intéressés, une synthèse actualisée de la classification des vertébrés de Roumanie. En compilant différentes sources bibliographiques, on a retenu un total de plus de 732 taxons d’ordre spécifique et sous-spécifique. Il s’agît des six grandes classes de vertébrés. La première classe (Cyclostomata) est représentée dans la faune de Roumanie par quatre espèces, tandis que Pisces (considérée ici au niveau de surclasse) l’est par 184 taxons. Le reste de 544 taxons font partie d’une autre surclasse (Tetrapoda) qui réunit les autres quatre classes de vertébrés: Amphibia (20 taxons); Reptilia (31); Aves (382) et Mammalia (110 taxons).

Kidney cell samples were taken from five male and five female fishes. The mitotic chromosome preparation was prepared directly from kidney cells. Conventional and Ag-NOR staining techniques were applied to stain the chromosomes. The results showed that the diploid chro- mosome number of S. ocellatus and S. picturatus were 2n=40, and the fundamental number (NF) was 40 in both males and females. The chromosomes were present as large telocentric, medium telocentric and small telocentric chromosomes in numbers of 16–18–6 and 14–24–2, respectively. No morphological difference was identified be- tween sex chromosomes of male and female specimens.

The whole mitogenome of most species was amplified as three fragments using the following primer sets: for the region between position 2 500 bp and 7 300 bp (of mitogenome starting with tRNA-Phe), we used forward primers ZM2500F (5'-ACG ACC TCG ATG TTG GAT CAG GAC ATC C-3'), L2508KAW (Kawaguchi et al. 2001) or S-LA-16SF (Miya & Nishida 2000) and reverse primer ZM7350R (5'-TTA AGG CGT GGT CGT GGA AGT GAA GAA G-3').

E-mail: [email protected] Abstract A new species of dragonet, Callionymus alisae from off New Ireland, Papua New Guinea, is described on the basis of a single male specimen collected with a grab dredge at 90-228 m depth, southwest of Kavieng. The new species is characterised within the subgenus Callionymus (Spinicapitichthys) by preopercular spine with a very short, straight main tip, four to five curved points on its dorsal margin, a strong antrorse spine at its base, and five to eight small serrae at its ventral margin; the dorsal margin of the eye with a tentacle, the dorsal fin in the male without filaments, the first spine longest; a total of 8 rays in the second dorsal fin and 7 rays in the anal fin; and the first dorsal fin in the male zebra-striped, with 4 vertical dark bands on 1st-4th membranes. The new species is compared with similar species. Revised keys to callionymid fish species of New Guinea, as well as of the subgenus Spinicapitichthys, are presented. Keywords: Fishes, Dragonets, New species, Identification key, New Guinea. Zoobank: urn:lsid:zoobank.org:pub:9F84BDFB-0863-46AB-8C0F-B0014E518592 Doi: Introduction Dragonets of the family Callionymidae are a group of benthic living fishes occurring in the upper 900 metres of all temperate, subtropical and tropical oceans of the world, and a few species found in estuarine and freshwater habitats.

Stuttgart, 15. 11. 2002 Annotated Checklist of the Dragonet Families Callionymidae and Draconettidae (Teleostei: Callionymoidei), with Comments on Callionymid Fish Classification By Ronald Fricke, Stuttgart With 1 figure and 2 tables Summary A revised checklist of callionymoid fishes (Perciformes) including the families Calliony- midae and Draconettidae is presented. A total of 310 nominal species of callionymoid fishes is included. The family Callionymidae contains 10 valid genera and 182 recent valid species (plus 5 fossil species). In the family Draconettidae, 2 genera with 12 valid species group taxa are known. Actual scientific names, English names, local names, references to original description and type locality of valid species and synonyms, type specimens, references to type catalogues, geographical distribution, actual classification, reference to source of taxonomic decision, and alternative classifications (if applicable) are given for each species. Callionymid fish classifications are compared, and a progress report on phylogenetic re- search is presented, outlining a new classification with several additional subgenera within the large genera Callionymus and Synchiropus which are supposed to be monophyletic. Several new distribution records of callionymid and draconettid fish species are included. Keywords: Checklist; classification; Teleostei; Callionymoidei; Callionymidae; Draco- nettidae.
