The presented work is the final part of the taxonomic revision of the Antarctic icefishes of the genus Channichthys Richardson, 1844 (Notothenioidei: Channichthyidae) from the Kerguelen Islands, the species composition of which was discussed until recently. Based on the morphological study of all available specimens from the ZIN and BMNH collections (including the holotype), a comprehensive redescription of the Red icefish Channichthys rugosus Regan, 1913 from the waters of the Kerguelen islands (South Ocean) was carried out, including external morphology, seismosensory system, gill apparatus, and axial skeleton. As a result, new diagnostic features of Red icefish were discovered and previously known ones were clarified, which made it possible to confirm the species validity. Comparison with other valid species icefishes was done. Channichthys rugosus differs from Ch. rhinoceratus Richardson, 1844 by a high anterior dorsal fin, the fin membrane of which reaches the apexes of its longest rays (does not reach in Ch. rhinoceratus), as well as a narrow and concave interorbital space (compared to the wider and flat one), by stronger granulation and a uniform reddish body color (dark spotted-marble in Ch. rhinoceratus). Channichthys rugosus differs from Ch. velifer Meissner, 1972 by the number of rays in the first dorsal fin (7–9 versus 9–12) and pectoral fin (18–20 versus 20–21), the presence of bone plaques in the proximal part of the medial lateral line (absent in Ch. velifer), and monochromatic reddish body coloration (spotted in Ch. velifer). Channichthys rugosus differs from Ch. panticapaei Shandikov, 1995 by the presence of only 1 row of gill rakers on the first gill arch (2 rows in Ch. panticapaei) and by light coloration (brownish-black in Ch. panticapaei).

The genus Microdaiphron Pic, 1926 is revised. Ten species are recognized as valid: Microdaiphron polemioides (Kirsch, 1889), M. implicitus (Erichson, 1847) comb. nov., M. pauloensis (Pic, 1926), M. peruvianus Pic, 1938, M. mendesensis (Pic, 1926), M. tapuruquara sp. nov., M. geodesicus sp. nov., M. batasitensis (Pic, 1926), M. guyanensis Constantin, 2016, and M. brevehumeralis Pic, 1938. Other 23 names within Microdaiphron are synonymized with the currently valid species, whilst Microdaiphron bicoloricornis Pic, 1947 is transferred to Malthesis Motschulsky, 1853. The taxonomic status of three primary homonyms is also discussed. Daiphron polemioides var. atripenne Pic, 1927 (=Microdaiphron implicitus comb. nov.) is the senior homonym of Daiphron atripenne Pic, 1934 and Daiphron atripenne var. bipartitum Pic, 1934. The later is synonymized and reinstated as a valid species under the name D. bipartitus Pic, 1934. Descriptions, distribution maps and illustrations of diagnostic features are presented for all valid taxa, including the photographs of primary types in all available names within Microdaiphron.

Fifteen holotypes of Asian Hesperiidae taxa described by Shu-iti Murayama were examined, and their taxonomic status is discussed. We confirm that five are valid names while the rest are synonyms as indicated partially by previous authors. Valid species-level names are Aeromachus matudai (Murayama), Aeromachus bandaishanus Murayama & Shimonoya, Coladenia pinsbukana (Shimonoya & Murayama), and Sebastonyma suthepiana Murayama & Kimura. Valid subspecies-level name is Ochlodes yuchingkina Murayama & Shimonoya. In order to settle the taxonomic status of Pedesta masuriensis cuneomaculata Murayama, masuriensis and tali were studied morphologically and molecularly. As a result, we consider that masuriensis and tali are two different species and treat cuneomaculata as a junior subjective synonym of tali.

Helicometrina nimia (Opecoelidae) is a digenean with wide distribution. Fish families most commonly used as hosts for H. nimia are Serranidae, Pomodasydae, Scorpaenidae and Clinidae. In the present study, a new host and a new host locality are presented for the species. A description of the studied specimens, besides comments concerning its taxonomic status and biometrically compared tables of H. nimia reports are given. The taxonomic status of members of Helicometrina has been questionable. The greatest controversy for the genus seems to be related to the validity of diagnostic features, especially in regard to the number of testes. In the present study, all studied specimens presented a permanent and steady number of testes (n=9) and therefore its use as a diagnostic character is supported by the present authors. Epinephelus marginatus is considered a new host for Helicometrina nimia, and São Paulo state, southeastern Brazil, a new locality for the species.

Gall Induction

Cynipidae (Hymenoptera: Cynipoidea) is a diverse group of wasps, many of which are capable of inducing plants to make novel structures, galls, that protect and nourish the wasps' larvae. Other cynipids, especially those species in Ceroptresini and Synergini, are understood to be usurpers of galls made by other cynipids. The North American cynipid fauna has not been fully cataloged since 1979, but there is renewed interest in revising the taxonomy and in doing research that sheds light on the mechanisms of gall induction, the evolution of this life history, and their ecological interactions more broadly. Significant taxonomic changes have impacted the group since 1979, thereby warranting a new catalog. The current state of knowledge of species classified in Aulacideini, Ceroptresini, Diastrophini, Diplolepidini, Phanacidini, and Synergini in the United States, Canada, and Mexico is summarized in catalog format. We report 323 names, including 170 valid species of rose gall wasps, herb gall wasps, and inquiline gall wasps, classified in 12 genera, from the United States, Canada, and Mexico. Current taxonomic status, distribution, host associations, and vernacular names are listed for each species. The catalog also includes the original description of galls for many species of gall-inducer, as well as atomized characterizations of different gall traits as key-value pairs. For most galling species without existing vernacular names, new vernacular names are proposed.

The name Flexopecten glaber ponticus (Bucquoy, Dautzenberg & Dollfus, 1889) is generally used for the only Pectinidae representative inhabiting the Black Sea. It is registered in the Red Book of the Republic of Crimea as endemic subspecies reducing in amount. F. glaber ponticus is listed in WoRMS MolluscaBase as the only accepted subspecies of Flexopecten glaber (Linnaeus, 1758). In the past its taxonomic status has been changed from a geographic variety to valid species. The purpose of this study is to establish its correct taxonomic status. The study is based on a comparative analysis of conchological features of Flexopecten glaber and F. glaber ponticus in relation with the brief natural history of population in the Black Sea. Sampling was performed by snorkel equipment in Kazach’ya Bay (Black Sea, Crimea, Sevastopol) at 2–6 m depths. A total of 100 scallop specimens were sampled in September 2017. To assure a better understanding in a broader context those results are compared with the previously published morphological data based on the analysis of a large amount of material from the Black Sea and the Mediterranean Sea – Marmara Sea regions. Comparative analysis of conchological features of F. glaber ponticus from the Black Sea with F. glaber from the Mediterranean region has not revealed any distinct differences between them. Thus, there are no evidenced data for the diagnosis of F. glaber ponticus as a subspecies. Species F. glaber appeared in the Black Sea not earlier than 7,000 years ago and formed a well developed population less than 3,000 years ago. We have to conclude that the specified divergence period is not long enough to form a subspecies. As a result of the present survey the subspecific status of F. glaber ponticus is not retained and the name is placed in synonymy of the parent species Flexopecten glaber.

The species of the genus Psammogorgia Verrill, 1868 from the shallow waters of the tropical eastern Pacific were mainly described from 1846 to 1870. Very few contributions were published subsequently. Recently, the genus was revisited with the addition of two new species. However, a comprehensive generic study is still missing for the eastern Pacific. Psammogorgia is characterised by having axes cores without mineralisation, mainly coarse irregular spindles and thorny, leafy or tuberculate clubs coenenchymal sclerites and the anthocodial armature with distinct collaret and points arrangements. Herein a taxonomic revision of the genus is presented based on type material which was morphologically analysed and illustrated using optical and scanning electron microscopy. Comparative character tables are provided for comparison among species in the genus, along with a taxonomic key. Moreover, the taxonomic status of each species was analysed. The genus Psammogorgia comprises six valid species and two varieties, and three lectotypes and a new combination are proposed to establish the taxonomic status of these species.

Cryptic Species Complex

To date, the genus Amphiduros (Annelida: Hesionidae: Amphidurine) is considered as monotypic. Its single species, Amphiduros fuscescens (Marenzeller, 1875), is well characterised by lacking proboscideal papillae and emerging acicular chaetae, as well as by having three antennae, eight pairs of tentacular cirri and inflated dorsal cirri with characteristic alternating length and colour (transparent, with median orange band and white tips) in live animals. Three specimens, one male and two females, were found below boulders at 5–7 m depth in Punta Santa Anna, Blanes and Cala Maset, Sant Feliu de Guixols (Catalan Sea, NW Mediterranean, Iberian Peninsula). Our finding allowed us to describe different, unreported morphological traits and lead us to support the existence of sexual dimorphism (in terms of colouring, cirri morphology and distribution of sexual products along the body). Despite A. fuscescens having been previously reported from the Atlantic and the Mediterranean (particularly in SE French coasts), the specimens from Blanes represent the first record of the species from the Iberian Peninsula. In addition, our molecular results strongly support that Amphiduros pacificus Hartman, 1961 from California (currently synonymised with A. fuscescens) requires to be re-described and reinstalled as a valid species. In turn, our morphological observations support suggesting all other non-Mediterranean reports of A. fuscescens, including the species still under synonymy (i.e. Amphidrornus izukai Hessle, 1925 and Amphidromus setosus Hessle, 1925) as likely being a cryptic species complex whose the taxonomic status requires further assessment.

Recent Attention

Recent attention to members of the sepiolid squid genusEuprymnaand symbiotic associations with luminescent bacteria (Vibrio fischeristrains) has prompted a review of this poorly-resolved group of squids. Twelve nominal species have been placed in this genus of which the majority are ill-defined, known only from their original descriptions and separated on the basis of inadequate characters. As a first step in resolving this group, a temperate Australian species, the Southern dumpling squid,Euprymna tasmanica, is here redescribed in detail. As the genusEuprymnacurrently stands, most members are only distinguished on the number and position of enlarged suckers in mature males. No diagnostic characters are available to identify females. All nominal species placed in this genus are reviewed and a key to proposed valid species is presented. Six species are considered here to be valid:Euprymna berryi, E. hoylei, E. morsei, E. scolopes, E. tasmanicaand an undescribed species treated here asEuprymnasp. 1.Euprymna similisis a synonym ofE. morseiof Japan. Due to inadequate original descriptions, and lost or poor type material, two species are considered here to benomen dubia(E. schneehageniandE. pusilla), while the taxonomic status of four additional species remain unresolved (E. albatrossae, E. bursa, E. phenaxandE. stenodactyla).

Critical Translation

The Dutch ichthyologist Pieter Bleeker described 34 species, including a new genus and five new species from a collection of fishes sent to him from the Cape of Good Hope by the French explorer, naturalist and diplomat, F.L. de Castelnau in 1858. A careful search of the Naturalis collection in Leiden found almost all the specimens received by Bleeker from Castelnau, including hitherto unrecognised types. Based on examination of this collection and a critical translation of Bleeker’s 1859 paper on the fishes of the Cape of Good Hope it has been possible to resolve the taxonomic status of Bleeker’s genus Pagrichthys (Pagrichthys castelnaui Bleeker, 1859, type by monotypy), previously considered a synonym of Sparus Linnaeus, 1758 but here regarded as a synonym of Lithognathus Swainson, 1839. The identity of the various species described by Bleeker, and type status of his new species are clarified: Cantharus castelnaui Bleeker, 1859 is a synonym of Pachymetopon blochii (Valenciennes, 1830); Pagrichthys castelnaui Bleeker, 1859 is a synonym of Lithognathus lithognathus (Cuvier, 1829); Seriola capensis Bleeker, 1859 (not previously recognised as a valid species) is a synonym of Seriola lalandi Valenciennes, 1833; Clinus dubuis Bleeker, 1859 (based on a misspelling of Castelnau’s ms name dubius) is a valid name, and a synonym of Clinus superciliosus (Linnaeus, 1758); and Clinus dorsalis Bleeker, 1859 is valid as Muraenoclinus dorsalis (Bleeker, 1859).
