A new cardinalfish, <Emphasis Type="Italic">Verulux solmaculata</Emphasis> (Perciformes: Apogonidae), from Papua New Guinea and Australia

Verulux solmaculata sp. nov., a new cardinalfish based on 88 specimens collected from Papua New Guinea and Australia, differs from V. cypselurus, the only other known member of the genus, by the following characters: higher modal numbers of pectoral fin-rays (16 vs. 15 in the latter) and developed gill rakers (14 vs. 13), a broader black band extending over 3–5 (mode 4) rays on each lobe of the caudal fin (vs. 1–3, mode 2), and a black blotch on the caudal-fin base (vs. blotch absent).     

<Emphasis Type="Italic">Erromyzon damingshanensis</Emphasis>, a new sucker loach (Teleostei: Cypriniformes: Gastromyzontidae) from the Pearl River drainage of Guangxi,China

Erromyzon damingshanensis, a new sucker loach is described from the Pearl River drainage in Guangxi, China. The new species Erromyzon damingshanensis is distinguished from the other species of the genus in having a crescentic median lobe of the rostral fold, rostral barbels shorter than rostral fold; postlabial groove broadly interrupted medially, seven branched dorsal fin rays, 16 branched pectoral fin rays, lateral line scales 88–95, caudal peduncle depth larger than its length; body with 12 irregular bars on flank, interrupted on dorsum.     

A new horned sculpin (Pisces: Cottidae) from the Miocene of Sakhalin Island,Russia

A new species of the Recent genus Enophrys, E. hoplites sp. nov., is described from the Miocene (Serravalian?Tortonian) Agnevo Formation of Sakhalin Island, Russia. This Miocene species differs from two Recent congeners in the greater number of anal fin rays (14 versus 9?13), the smaller head, less raised margins of the orbit, flatter upper contour of the head, longer anal fin base, short predorsal distance, higher first dorsal fin, and in the right angle (versus acute angle) between two upper preopercular spines. An archaic feature of the new species is the presence of two rays on the posterior pterygiophore of the anal fin, a character recorded only in the most primitive Recent members of the family. The occurrence of this new fossil species shows that extant subfamilies, tribes, and genera existed as a part of the family Cottidae as early as the Miocene time.     

Gall midges of the supertribe stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic region,with descriptions of new taxa from the late Eocene Rovno Amber. 2. The genera <Emphasis Type="Italic">Didactylomyia</Emphasis> and <Emphasis Type="Italic">Rovnodidactylomyia</Emphasis> gen. n.

One new genus (Rovnodidactylomyia Fedotova et Perkovsky, gen. n.) and four new species (Didactylomyia dlusskyi sp. n., Rovnodidactylomyia zosimovichi gen. n. et sp. n., R. sidorenkoi sp. n., and R. iconica sp. n.) are described from an amber sample of the late Eocene Period (Rovno District, Ukraine). Two species from a Baltic amber sample of the late Eocene Period, described earlier in the genus Bryocrypta, are attributed to the genus Rovnodidactylomyia (R. girafa (Meunier, 1904) comb. n. and R. capitosa (Meunier, 1904)). The first fossil species of the genus Didactylomyia is described for the first time; two contemporary Palaearctic species are recorded. Keys to the species of the genus Didactylomyia are given.     

Review of the <Emphasis Type="Italic">Chromis xanthura</Emphasis> species group (Perciformes: Pomacentridae), with description of a new species

A taxonomic review of the Chromis xanthura species group, defined here as having 13 dorsal-fin spines, three upper and three lower procurrent caudal-fin rays, two black bands at the preopercular and opercular margins, and a yellow caudal fin when juvenile, resulted in the recognition of three species, Chromis xanthura (Bleeker 1854), Chromis opercularis (Günther 1867), and Chromis anadema sp. nov. Chromis xanthura and C. opercularis, the Pacific and Indian Ocean paired sister species, respectively, are redescribed, with confirmation of two color types of C. xanthura (having a white or black caudal peduncle and fin) as a single species on the basis of morphological and molecular analyses. Chromis anadema sp. nov., described from the oceanic islands of the Pacific Ocean on the basis of 21 specimens, is characterized by having 28–33 gill rakers; longest dorsal-fin soft ray length 20.0–24.7% of standard length (SL); first anal-fin spine length 5.0–6.1% of SL; caudal-fin length 33.4–43.8% of SL; posterior tips of caudal-fin lobes not filamentous in adults; broad black bands along preopercular and opercular margins, sum width of two bands 28.9–38.7% of head length; distal half of soft-rayed portion of dorsal fin transparent in adults; triangular black blotches at upper and lower caudal-fin base in adults; caudal peduncle and fin bluish black in adults; and body grayish, and all fins (except for pectoral fin) bright yellow in juveniles.     

<Emphasis Type="Italic">Careproctus iacchus,</Emphasis> a new variegated snailfish (Liparidae) from the Seas of Japan and Okhotsk

A new species of snailfishes, Careproctus iacchus, is described on the basis of three specimens collected from the Seas of Japan and Okhotsk. Among the species of Careproctus, the new species is most similar to Careproctus comus and Careproctus faunus, both known from the Aleutian Islands, in having a variegated body coloration. However, it can be distinguished in having 44–46 dorsal- and 39–40 anal-fin rays (vs. 50–56 and 44–50 in C. comus and 47–51 and 41–45 in C. faunus, respectively), a pectoral fin without a notch (vs. both with a shallow notch), no interradial fenestra between proximal radials two and three in the pectoral girdle (vs. both having a fenestra between proximal radials two and three), a gill slit entirely above the pectoral fin (extending to just above the pectoral fin or to 1–5th ray), a body with many white spots (vs. mottled with red and white), and a large white blotch on cheek (vs. no distinct markings on cheek) when fresh.     

A review of the <Emphasis Type="Italic">Gerres subfasciatus</Emphasis> complex from the Indo-West Pacific,with three new species (Perciformes: Gerreidae)

Gerres japonicus Bleeker, 1854, and Gerres subfasciatus Cuvier in Cuvier and Valenciennes, 1830, are redescribed, and Gerres akazakii sp. nov. (Japanese endemic), Gerres ryukyuensis sp. nov. (Okinawa I., Japan), and Gerres shima sp. nov. (Indo-Malayan region, including the Andaman Sea, Southeast Asia, southern China and Taiwan, and Ryukyu Is., Japan) are described. Gerres ovatus Günther, 1859, and Gerres kapas Bleeker, 1854, are recognized as junior synonyms of G. subfasciatus and Gerres oyena (Forsskål, 1775), respectively. All species (except G. oyena) have a small (<170?mm in standard length: SL), moderately deep (depth 36–48% SL), body with dark vertical bars, dorsal fin rays X, 9 or IX, 10, and 31/2 or 41/2 scale rows between the 5th dorsal fin spine base and lateral line, defined as the G. subfasciatus complex. The five species can be variously differentiated from each other by dorsal head squamation, and differing meristic, morphometric, and color characters. They are generally distributed sympatrically in the Indo-West Pacific. Other nominal species of uncertain status or relationship are discussed.     

Review of the species of the genus <Emphasis Type="Italic">Leptomastidea</Emphasis> Mercet, 1916 (Hymenoptera,Encyrtidae) of the World,with description of a new species from Montenegro and with separation of a new genus from Turkmenia

The review contains a key to females of the species of the genus Leptomastidea Mercet, 1926 of the World fauna and annotated synopsis of 25 species with data on their distribution, hosts, plants, and use in biological control [for L. abnormis (Girault)]. L. ljubodragi sp. n. is described from Montenegro. A new genus Proleptomastidea gen. n. is erected for Leptanusia enigmatica Trjapitzin, 1971 from Turkmenistan. Leptanusia turkmenica Myartseva, 1978 is transferred to the genus Anagyrus Howard, 1896 and, thus, a new combination, Anagyrus turkmenicus (Myartseva, 1978), comb. n., is formed.     

Contribution to the phylogeny and a new species of <Emphasis Type="Italic">Coccodiella</Emphasis> (Phyllachorales)

Coccodiella is a genus of plant-parasitic species in the family Phyllachoraceae (Phyllachorales, Ascomycota), i.e., tropical tar spot fungi. Members of the genus Coccodiella are tropical in distribution and are host-specific, growing on plant species belonging to nine host plant families. Most of the known species occur on various genera and species of the Melastomataceae in tropical America. In this study, we describe the new species C. calatheae from Panama, growing on Calathea crotalifera (Marantaceae). We obtained ITS, nrLSU, and nrSSU sequence data from this new species and from other freshly collected specimens of five species of Coccodiella on members of Melastomataceae from Ecuador and Panama. Phylogenetic analyses allowed us to confirm the placement of Coccodiella within Phyllachoraceae, as well as the monophyly of the genus. The phylogeny of representative species within the family Phyllachoraceae, including Coccodiella spp., graminicolous species of Phyllachora and taxa with erumpent to superficial stroma from several host families, suggests that the genus Phyllachora might be polyphyletic. Furthermore, tar spot fungi with superficial or erumpent perithecia seem to be restricted to the family Phyllachoraceae, independently of the host plant. We also discuss the biodiversity and host-plant patterns of species of Coccodiella worldwide.     

Redescription of <Emphasis Type="Italic">Lagocephalus cheesemanii</Emphasis> (Clarke 1897), a senior synonym of <Emphasis Type="Italic">Lagocephalus gloveri</Emphasis> Abe and Tabeta 1983, based on morphological and genetic comparisons (Actinopterygii: Tetraodontiformes: Tetraodontidae)

Lagocephalus gloveri Abe and Tabeta 1983 is shown to be a junior synonym of Tetrodon cheesemanii Clarke 1897 based on examination of morphological characters and DNA analysis of specimens collected from the western North Pacific, Australia and New Zealand. Lagocephalus cheesemanii is distinguished from other species of Lagocephalus by the following combination of characters: spinules on the back in a rhomboidal patch extending from the region between the nasal organ to the posterior part of the pectoral fin; caudal fin double emarginate with middle rays posteriorly produced; dorsal-fin rays 11–15; anal-fin rays 11–14; pectoral-fin rays 15–18; vertebrae 8+11=19; dorsal half of the body dark brown to brownish black; caudal fin dark brown to black with dorsal and ventral white tips. A neotype of L. cheesemanii is designated.     

Review of Indo-Pacific dwarf lionfishes (Scorpaenidae: Pteroinae) in the <Emphasis Type="Italic">Dendrochirus brachypterus</Emphasis> complex,with description of a new species from the western Indian Ocean

A taxonomic review of the Dendrochirus brachypterus complex resulted in the recognition of five species, including Dendrochirus barberi (Steindachner 1900), Dendrochirus bellus (Jordan and Hubbs 1925), Dendrochirus brachypterus (Cuvier in Cuvier and Valenciennes 1829), Dendrochirus hemprichi sp. nov. and Dendrochirus tuamotuensis Matsunuma and Motomura 2013. The complex is defined as having usually 9 dorsal-fin soft rays, usually 5 anal-fin soft rays, 17–20 (rarely 20) pectoral-fin rays, no ocellated spots on the soft-rayed portion of the dorsal fin and usually 2 (sometimes none) barbels on the snout tip. Dendrochirus barberi, known from the Hawaiian Islands and Johnston Atoll, is characterized by usually 18 pectoral-fin rays, a relatively high number of scale rows in the longitudinal series (modally 51 vs. 39–49 in other species) and mottled markings on the pectoral fin in large specimens. Dendrochirus bellus, restricted to the northwestern Pacific Ocean from the South China Sea north to southern Japan, is characterized by usually 17 pectoral-fin rays, a relatively low number of scale rows in the longitudinal series (modally 38 vs. 44–51 in other species), and the absence of skin flaps on the orbit surface and uppermost preopercular spine base. Dendrochirus tuamotuensis, recorded only from the Tuamotu Archipelago, is characterized by 19 pectoral-fin rays, the posterior margin of the pectoral fin strongly notched, and a relatively shallow and narrow head and body. Dendrochirus hemprichi sp. nov. is distributed in the western Indian Ocean, including the Red Sea. Although previously confused with a closely related congener (D. brachypterus, known from the northern and eastern Indian Ocean and western Pacific), D. hemprichi can be distinguished from the former by having fewer scale rows between the last dorsal-fin spine base and lateral line, and between the sixth dorsal-fin spine base and lateral line [4–7 (5) in D. hemprichi vs. 5–7 (6) in D. brachypterus, in both cases], a slightly greater interorbital width at the mid-orbit [5.5–10.7 (mean 7.8) % SL vs. 4.5–8.9 (6.8) % of SL] and at preocular spine base [4.4–9.1 (6.6) % SL vs. 3.5–7.8 (5.7) % of SL], and slightly shorter posteriormost (usually 13th) dorsal-fin spine length [11.8–19.9 (15.3) % SL vs. 13.3–21.3 (17.2) % of SL]. Moreover, D. hemprichi tends to have relatively more spinous points on the head spines and ridges, compared with D. brachypterus. Notwithstanding the morphological similarity between the two species, an obvious genetic difference was observed between D. hemprichi and D. brachypterus. Dendrochirus chloreus Jenkins 1903 and Dendrochirus hudsoni Jordan and Evermann 1903 were synonymized under Pterois barberi, as in some previous studies. Scorpaena koenigii Bloch 1789 was regarded as conspecific with D. brachypterus, which it predated. However, the former name should be suppressed under Reversal of Precedence.     

Gall midges of the supertribe Stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic Region,with descriptions of new taxa from the Late Eocene Rovno amber: 1. <Emphasis Type="Italic">Stomatosema,Vanchidiplosis, Clarumreddera</Emphasis> gen. n.

Three recent genera are included in the supertribe Stomatosematidi: Stomatosema (16 species), Vanchidiplosis (4 species), and Didactylomyia (3 species). Seven species of the genus Stomatosema and two species of the genus Vanchidiplosis occur in the Palaearctic Region. No reliable findings of representatives of the supertribe were known in fossilized condition. One new genus and 3 new species are described from amber of the Late Eocene age (Rovno Region): Stomatosema iljieteugeniae sp. n., Clarumreddera korneyevi gen. n. et sp. n., and C. conceptiva sp. n.     

Taxonomic revisions in the Microstromatales: two new yeast species,two new genera,and validation of <Emphasis Type="Italic">Jaminaea</Emphasis> and two <Emphasis Type="Italic">Sympodiomycopsis</Emphasis> species

Environmental sampling yielded two yeast species belonging to Microstromatales (Exobasidiomycetes, Ustilaginomycotina). The first species was collected from a leaf phylloplane infected by the rust fungus Coleosporium plumeriae, and represents a new species in the genus Jaminaea, for which the name Jaminaea rosea sp. nov. is proposed. The second species was isolated from air on 50% glucose media and is most similar to Microstroma phylloplanum. However, our phylogenetic analyses reveal that species currently placed in Microstroma are not monophyletic, and M. phylloplanum, M. juglandis and M. albiziae are not related to the type species of this genus, M. album. Thus, Pseudomicrostroma gen. nov. is proposed to accommodate the following species: P. glucosiphilum sp. nov., P. phylloplanum comb. nov. and P. juglandis comb. nov. We also propose Parajaminaea gen. nov. to accommodate P. albizii comb. nov. and P. phylloscopi sp. nov. based on phylogenetic analyses that show these are not congeneric with Jaminaea or Microstroma. In addition, we validate the genus Jaminaea, its respective species and two species of Sympodiomycopsis and provide a new combination, Microstroma bacarum comb. nov., for the anamorphic yeast Rhodotorula bacarum. Our results illustrate non-monophyly of Quambalariaceae and Microstromataceae as currently circumscribed. Taxonomy of Microstroma and the Microstromataceae is reviewed and discussed. Finally, analyses of all available small subunit rDNA sequences for Jaminaea species show that J. angkorensis is the only known species that possess a group I intron in this locus, once considered a potential feature indicating the basal placement of this genus in Microstromatales.     

A new species of eel cods <Emphasis Type="Italic">Muraenolepis kuderskii</Emphasis> sp. nova (fam. Muraenolepididae) from South Georgia (the Scotia Sea)

A new species of the eel cod Muraenolepis kuderskii sp. nova from the Scotia Sea, South Georgia, from depths of 440–605 m is described. The species belongs to the group of “few-rayed” species having less than 150 rays in the dorsal fin and less than 114 rays in the anal fin. According to general body proportions, M. kuderskii is closely related to high-latitude Antarctic species M. trunovi; however, it differs from the latter and all other species of the group of “few-rayed” eel cods in a short chin barbel, small sizes of the eye, a short antebranchial distance, a short anteanal distance, and a long postanal distance.     

A new species of grayling <Emphasis Type="Italic">Thymallus svetovidovi</Emphasis> sp. nova (Thymallidae) from the Yenisei basin and its position in the genus <Emphasis Type="Italic">Thymallus</Emphasis>

The Upper Yenisei grayling Thymallus svetovidovi sp. nova that inhabits the headwaters of the Yenisei River in Mongolia is described. From the other representatives of the genus Thymallus, the species differs in the elements of body coloration, dorsal fin pattern, some morphometric characters, and genetic characteristics. Besides this species, most of the Yenisei basin is inhabited by Baikal grayling T. baicalensis Dyb., and its low reaches, by the Arctic grayling T. arcticus (Pall.).     

On discovery of the weevil genus <Emphasis Type="Italic">Nanomicrophyes</Emphasis> Pic, 1908 (Coleoptera,Curculionidae) in China

A new subgenus Sinomicrophyes subgen. n. with four new species Nanomicrophyes belousovi sp. n. (type species), N. korolevi sp. n., N. oblongus sp. n., and N. kabaki sp. n. from Western China is erected in the genus Nanomicrophyes Pic, 1908 previously known from a single species distributed in the Caucasus. A map of the genus Nanomicrophyes range is provided with a brief discussion of the N. cyanipennis (Weise, 1880) distribution.     

A new genus of Elateriform beetles (Coleoptera,Polyphaga) from the Middle-Late Jurassic of Karatau

A new coleopteran genus, Anacapitis gen. nov., comprising A. karataviensis sp. nov., A. incertus sp. nov., and A. oblongus sp. nov., is described from the Karabastau Formation of the Karatau locality (southern Kazakhstan, Middle-Late Jurassic) in the infraorder Elateriformia. The systematic position of the new genus within the suborder Polyphaga is discussed.     

A new species of labrid fish <Emphasis Type="Italic">Oxycheilinus samurai</Emphasis> from the western Pacific Ocean

A new species of labrid fish Oxycheilinus samurai sp. nov. is described on the basis of five specimens from the Ryukyu Islands, Japan, and Panay Island, the Philippines. The new species is most similar to the Indo-West Pacific species Oxycheilinus orientalis in having a slender compressed body, 12 pectoral-fin rays, a blackish blotch around the anterior portion of the lateral-line anterior series, and a dark blotch basally on the membrane between the first and second dorsal-fin spines. However, O. samurai can be distinguished from O. orientalis by the following combination of characters: gill rakers 4 + 7–8; snout rounded with maximum circumference 49.8–63.5 % of standard length (SL); interorbital width 7.7–9.2 % of SL; caudal-peduncle depth 13.8–15.3 % of SL; posterior margin of caudal fin white; black or dark red area just before white posterior margin of caudal fin; poorly defined blackish blotches on inner surface of opercle in preserved specimens.
