Two new species of <Emphasis Type="Italic">Sagum</Emphasis> Wilson, 1913 (Copepoda: Siphonostomatoida: Lernanthropidae) parasitic on reef fishes off the Ryukyu Islands

Two new species of parasitic copepods, Sagum gurukun n. sp. and S. bitaro n. sp. (Siphonostomatoida: Lernanthropidae), are described based on specimens collected from the gill filaments of the double-lined fusilier Pterocaesio digramma (Bleeker) (Actinopterygii: Perciformes: Caesionidae) and the five-lined snapper Lutjanus quinquelineatus (Bloch) (Actinopterygii: Perciformes: Lutjanidae), respectively, caught off Iriomote-jima Island, the Ryukyu Islands, East China Sea, Japan. The findings bring the number of species of Sagum to 14. The two new species are similar in the morphology of the head and the legs 3 and 4 to the three congeners, S. folium Ho, Liu & Liu, 2011, S. paracaesionis Izawa, 2014 and S. vietnamiensis Kazachenko, Kovaleva, Nguyen & Ngo, 2017. Sagum gurukun n. sp. is differentiated from the three congeners by the proportions of the caudal rami, the absence of leg 5, and the shape of the legs 1 and 2. Sagum bitaro n. sp. differs from the three congeners and S. gurukun n. sp. by the presence of the conical leg 5 armed with an apical seta. A key to the species of the genus Sagum, based on the available information on female morphology in previous publications and the present study, is provided. To date, a total of 19 species of lernanthropid copepods considered valid are known in Japanese waters.     

Two new and one known species of <Emphasis Type="Italic">Tergestia</Emphasis> Stossich, 1899 (Trematoda: Fellodistomidae) with novel molecular characterisation for the genus

Combined morphological and molecular analyses are employed to characterise three species of Tergestia Stossich, 1899 (Digenea: Fellodistomidae) from fishes of Moreton Bay, Queensland, Australia. Tergestia clonacantha Manter, 1963 is reported here for the first time from the halfbeak (Beloniformes: Hemiramphidae) species Arrhamphus sclerolepis krefftii (Steindachner), Hyporhamphus australis (Steindachner), H. quoyi (Valenciennes) and H. regularis ardelio (Whitley). Two new species, both infecting trevally (Perciformes: Carangidae) species, are described: T. maryae n. sp. from Alepes apercna Grant and T. henryi n. sp. from Pantolabus radiatus (MacLeay). Complete ITS2 and partial 28S ribosomal DNA data were generated for each of the new taxa. The three species differ from each other by 47–58 base pairs (bp) in the ITS2 rDNA region. Phylogenetic analysis of 28S rDNA supports Tergestia as a reliable generic concept, with our analyses showing that some species of the genus form a well-supported clade to the exclusion of all other fellodistomids for which sequence data are available.     

Morphology and molecules reveal the alien <Emphasis Type="Italic">Posthodiplostomum centrarchi</Emphasis> Hoffman, 1958 as the third species of <Emphasis Type="Italic">Posthodiplostomum</Emphasis> Dubois, 1936 (Digenea: Diplostomidae) in Europe

Metacercariae of two species of Posthodiplostomum Dubois, 1936 (Digenea: Diplostomidae) were subjected to morphological and molecular studies: P. brevicaudatum (von Nordmann, 1832) from Gasterosteus aculeatus (L.) (Gasterosteiformes: Gasterosteidae), Bulgaria (morphology, cox1 and ITS1-5.8S-ITS2) and Perca fluviatilis L. (Perciformes: Percidae), Czech Republic (morphology, cox1, ITS1-5.8S-ITS2 and 28S); and P. centrarchi Hoffman, 1958 from Lepomis gibbosus (L.) (Perciformes: Centrarchidae), Bulgaria (morphology, cox1 and ITS1-5.8S-ITS2) and Slovakia (cox1 and ITS1-5.8S-ITS2). In addition, cercariae of P. cuticola (von Nordmann, 1832) from Planorbis planorbis (L.) (Mollusca: Planorbidae), Lithuania (morphology and cox1) and metacercariae of Ornithodiplostomum scardinii (Schulman in Dubinin, 1952) from Scardinius erythrophthalmus (L.) (Cypriniformes: Cyprinidae), Czech Republic, were examined (morphology, cox1, ITS1-5.8S-ITS2 and 28S). These represent the first molecular data for species of Posthodiplostomum and Ornithodiplostomum Dubois, 1936 from the Palaearctic. Phylogenetic analyses based on cox1 and ITS1-5.8S-ITS2, using O. scardinii as the outgroup and including the three newly-sequenced Posthodiplostomum spp. from Europe and eight published unidentified (presumably species-level) lineages of Posthodiplostomum from Canada confirmed the distinct status of the three European species (contrary to the generally accepted opinion that only P. brevicaudatum and P. cuticola occur in the Palaearctic). The subspecies Posthodiplostomum minimum centrarchi Hoffmann, 1958, originally described from North America, is elevated to the species level as Posthodiplostomum centrarchi Hoffman, 1958. The undescribed “Posthodiplostomum sp. 3” of Locke et al. (2010) from centrarchid fishes in Canada has identical sequences with the European isolates of P. centrarchi and is recognised as belonging to the same species. The latter parasite, occurring in the alien pumpkinseed sunfish Lepomis gibbosus in Europe, is also supposed to be alien for this continent. It is speculated that it colonised Europe long ago and is currently widespread (recorded in Bulgaria, Slovakia and Spain); based on the cox1 sequence of an adult digenean isolate from the Ebro Delta, Spain, only the grey heron (Ardea cinerea L.) (Ciconiiformes: Ardeidae) is known to be its definitive host in Europe.     

Review of the genus <Emphasis Type="Italic">Banjos</Emphasis> (Perciformes: Banjosidae) with descriptions of two new species and a new subspecies

A taxonomic review of the genus Banjos (Perciformes: Banjosidae), previously restricted to a single species, Banjos banjos (Richardson 1846), recorded from the northwestern Pacific Ocean from the South China Sea north to Japan, as well as Lombok (Indonesia), New Caledonia and Australia, resulted in the recognition of three species, including B. banjos (northwestern Pacific Ocean, Indonesia and western Australia), Banjos aculeatus sp. nov. (eastern Australia) and Banjos peregrinus sp. nov. [northern Australia (Timor Sea)]. Records of B. banjos from New Caledonia probably also represent B. aculeatus, which is clearly distinct from other congeners in having a relatively long, strongly serrated spine at the posteroventral angle of the preopercle and an entirely dusky membrane on the spinous dorsal fin in juveniles < ca. 70 mm SL, in addition to slightly longer first and second dorsal-fin spines. Banjos peregrinus is characterized by a relatively greater head length, orbit diameter, postorbital length and pre-pelvic-fin length, as well as poorly developed serration of the exposed margin of the cleithrum. Within B. banjos, a population from the southeastern Indian Ocean, including Indonesia and western Australia, is regarded as a distinct subspecies (Banjos banjos brevispinis ssp. nov.), distinguishable from B. b. banjos from the northwestern Pacific Ocean by a relatively narrow least interorbital width, and shorter second and eighth dorsal-fin spines. Ontogenetic morphological changes within the genus and the status of the holotype of Anoplus banjos Richardson 1846 are discussed in detail.     

<Emphasis Type="Italic">Pseudodelphis eleginopsis</Emphasis> n. sp. (Nematoda: Guyanemidae), a new tissue-dwelling parasite of the Patagonian blennie <Emphasis Type="Italic">Eleginops maclovinus</Emphasis> (Cuvier) (Perciformes: Eleginopsidae) in Argentina,with notes on related forms

Based on light and scanning electron microscopical studies, a new nematode parasite, Pseudodelphis eleginopsis n. sp. (Dracunculoidea: Guyanemidae), is described from tissues behind the gills of the Patagonian blennie Eleginops maclovinus (Cuvier) (Perciformes: Eleginopsidae) off the Atlantic coast (San Matías and San José Gulfs) of Patagonia, Argentina. The new species is mainly characterised by the length of the body (males 10–13 mm, larvigerous females 31–59 mm), the number (14) and arrangement of cephalic papillae, the absence of a buccal capsule, the muscular to glandular oesophagus length ratio (1:3–4) of larvigerous females, the length of the spicules (48–63 µm) and the number (7 pairs) and arrangement of the caudal papillae in the male. Pseudodelphis eleginopsis n. sp. is the first species of this genus described from a marine fish in the Atlantic Ocean and the first known dracunculoid parasitising the fish host belonging to the family Eleginopsidae. As revealed by the examination of very young females of the new species, the female genital tract of Pseudodelphis spp. is monodelphic. The genus Syngnathinema Moravec, Spangenberg & Frasca, 2001 is considered a junior synonym of Pseudodelphis Adamson & Roth, 1990 and, consequently, S. californiense and S. chitwoodi are transferred to Pseudodelphis as P. californiensis (Moravec, Spangenberg & Frasca, 2001) n. comb. and P. chitwoodi (Moravec & Kuchta, 2013) n. comb., respectively. Two dracunculoid species, Pseudodelphis limnicola Brugni & Viozzi, 2006 and the previously established Philonema percichthydis Moravec, Urawa & Coria, 1997, both described from the same freshwater host species, Percichthys trucha (Valenciennes), in the same region (Patagonia), are considered to be identical; therefore, the valid name of this species is Pseudodelphis percichthydis n. comb. and P. limnicola becomes its junior synonym. A key to the species of Pseudodelphis is provided.     

<Emphasis Type="Italic">Barracudia australiensis</Emphasis> n. g., n. sp. (Nematoda: Philometridae) from the obtuse barracuda <Emphasis Type="Italic">Sphyraena obtusata</Emphasis> Cuvier (Perciformes: Sphyraenidae) off eastern Australia

Based on light and scanning electron microscopical studies, a new nematode parasite, Barracudia australiensis n. sp. (Philometridae), is described from the gall-bladder of the marine fish (obtuse barracuda) Sphyraena obtusata Cuvier (Sphyraenidae, Perciformes) from off the eastern Pacific coast of Australia, for which a new genus Barracudia n. g. is established. This new genus is mainly characterised by features found in the male: sickle-shaped, ventrally curved spicules, a gubernacum with a broad, dorsally bent distal portion and a markedly dorsoventrally elongated cloacal aperture. Based on these features, Barracudia spp. conspicuously differ from representatives of all other philometrid genera with known males. Philometra philippinensis Quiazon & Yoshinaga, 2013 is transferred to Barracudia as B. philippinensis (Quiazon & Yoshinaga, 2013) n. comb. Barracudia australiensis is the third nominal species of philometrids described from the Sphyraenidae and the 19th species of the Philometridae recorded from fishes in Australian waters.     

Three new species of <Emphasis Type="Italic">Plagioporus</Emphasis> Stafford, 1904 from darters (Perciformes: Percidae), with a redescription of <Emphasis Type="Italic">Plagioporus boleosomi</Emphasis> (Pearse, 1924) Peters, 1957

A form of Plagioporus Stafford, 1904 is described from the intestine of three North American species of darters (Perciformes: Percidae) from River West Twin, Wisconsin, USA, that we consider to be conspecific with Plagioporus boleosomi (Pearse, 1924) Peters, 1957 based on similarities in the sucker ratio, extent of the forebody, shape and position of the testes, vitellarium distribution and terminal genitalia. Three new species of Plagioporus are described from the intestine of darters as follows: Plagioporus fonti n. sp. from Percina nigrofasciata Agassiz in Florida, USA, Plagioporus limus n. sp. from Etheostoma squamosum Distler in Arkansas, USA and Plagioporus aliffi n. sp. from Etheostoma blennioides newmanni Miller in Arkansas, USA. Morphologically Plagioporus fonti n. sp., Plagioporus limus n. sp. and Plagioporus aliffi n. sp. are most similar to one another and to P. boleosomi, Plagioporus lepomis Dobrovolny, 1939 and ‘P. etheostomae’, a nomen nudum for a species described from Etheostoma blennioides Rafinesque in Kentucky, USA, all of which are collectively distinguished from congeners in having a combination of confluent vitellarium in the post-testicular space and absence of vitelline follicles with their entire length distributed in the forebody. Plagioporus fonti n. sp., P. limus n. sp. and P. aliffi n. sp. are respectively distinguished from one another and their closest congeners in having the anterior extent of the vitellarium in the anterior half of forebody to slightly anterior to the ventral sucker as opposed to one approximately at the level of the posterior margin of the ventral sucker, possession of an excretory vesicle reaching the anterior testis as opposed to one only reaching the posterior testis and having a longer than wide oral sucker and a wider than long ventral sucker. A Bayesian inference (BI) analysis of partial 28S rDNA sequences was conducted using the three new species and 24 sequences of opecoelids retrieved from GenBank, including ten species of Plagioporus. Plagioporus aliffi n. sp., Plagioporus fonti n. sp. and P. boleosomi comprised a moderately supported sister group to a clade containing all species of Plagioporus except Plagioporus limus n. sp. and Plagioporus shawi (Mcintosh, 1939) Margolis, 1970. Plagioporus limus and in turn P. shawi were resolved as sister to all other congeners with high and moderate support, respectively.     

A new genus of African Lasiocampidae (Lepidoptera)

The species Gastroplakaeis idakum Bethune-Baker, 1913, G. balia Tams, 1929, and G. elongata Hering, 1941 are transferred from the genus Gastroplakaeis Möschler, 1887 into the newly erected genus Weirdonia gen. n. (the type species is Gastroplakaeis idakum Bethune-Baker, 1913), and corresponding new combinations are established. New species, Weirdonia baccara sp. n. and W. hypocrita sp. n. (type locality: Democratic Republic of the Congo), W. murena sp. n. (type locality: Northern Nigeria), and W. helicea sp. n. (type locality: Gabon) are described. A new synonymy is established: Gastroplakaeis balia Tams, 1929 = Gastroplakaeis elongata Hering, 1941 syn. n. Diagnoses and distribution maps are given for all the species.     

Morphological and molecular study of <Emphasis Type="Italic">Longicollum pagrosomi</Emphasis> Yamaguti, 1935 (Acanthocephala: Pomphorhynchidae) from the barred knifejaw <Emphasis Type="Italic">Oplegnathus fasciatus</Emphasis> (Temminck &amp; Schlegel) (Perciformes: Oplegnathidae) in the East China Sea

Longicollum pagrosomi Yamaguti, 1935 (Acanthocephala: Pomphorhynchidae) collected from the barred knifejaw Oplegnathus fasciatus (Temminck & Schlegel) (Perciformes: Oplegnathidae) in the East China Sea (off Zhoushan Islands) was studied using light and scanning electron microscopy. The SEM observations revealed for the first time the presence of about 28 well-developed sensory papillae arranged in a circle on the copulatory bursa. In addition, L. pagrosomi was characterised using molecular methods by sequencing of the internal transcribed spacer (ITS) of the ribosomal DNA based on the newly collected material. Longicollum pagrosomi is the first species of the genus with the ITS region sequenced for the purpose of species identification. These new morphological and molecular data contributed to a reliable and accurate specific identification and differentiation of species.     

<Emphasis Type="Italic">Aethycteron robisoni</Emphasis> n. sp. (Monogenea: Ancyrocephalidae) from the sunburst darter, <Emphasis Type="Italic">Etheostoma mihileze</Emphasis> Mayden (Perciformes: Percidae), in Arkansas,USA

Aethycteron robisoni n. sp. is described from the sunburst darter, Etheostoma mihileze Mayden (Perciformes: Percidae), in the Arkansas River Drainage of the Ozark Region in the Central Highlands of Arkansas, USA. Aethycteron robisoni morphologically most closely resembles A. caerulei Suriano & Beverley-Burton, 1982, A. moorei (Mizelle, 1940) and A. nigrei Suriano & Beverly-Burton, 1982, by possessing a male copulatory organ with a distinct distal curvature and spiraling sheath. The haptoral sclerites of A. robisoni, with the exception of the hooks, are distinctly larger than those of the other three species. This is the first time a monogenean parasite has been reported from E. mihileze as well as the first time the genus Aethycteron Suriano & Beverley-Burton, 1982 has been reported from Arkansas, USA.     

Descriptions of two new species of feather mites (Acarina: Psoroptidia: Pteronyssidae) from Ivory Coast

Two new feather mite species of the family Pteronyssidae Oudemans, 1941 collected from birds captured in Ivory Coast are described: Pteronyssoides cyanomitrae n. sp. from Cyanomitra obscura (Jardine) (Passeriformes: Nectariniidae) and Conomerus pygmaeus n. sp. from Hylia prasina (Cassin) (Passeriformes: Macrosphenidae). Pteronyssoides cyanomitrae n. sp. belongs to the nectariniae species group and differs from the closest species, P. garioui Gaud & Mouchet, 1959, in having, in males, the adanal shield present and setae f longer than setae d on the tarsus III; females of this species have the hysteronotal shield with two small median incisions on the anterior margin barely extending beyond the level of setae e2. Conomerus pygmaeus n. sp. is the first species of this genus found on a passerine host, and seems to be more similar to C. sclerosternus Gaud, 1990. This new species has the following distinctive characters: in females, the opisthosoma has small lobe-like extensions and the central sclerite is fused posteriorly with the lateral opisthosomal sclerites; in males, coxal fields I–IV lack large sclerotised areas.     

A new subgenus and a new species of the tenebrionid genus <Emphasis Type="Italic">Leptodes</Emphasis> Dejean, 1834 (Coleoptera,Tenebrionidae)

The genus Leptodes was erected by Dejean (1834) for a single species, Sepidium boisduvalii Zubkoff, 1833, which is, consequently, the type species by monotypy. Kaszab (1959) established in Leptodes the subgenus Leptodinopsis based on the same type species, Sepidium boisduvalii. Thus the names Leptodes and Leptodinopsis are objective synonyms: Leptodes Dejean, 1834 = Leptodinopsis Kaszab, 1959, syn. n. A new subgenus Mesoleptodes G. Medvedev et Iljina subgen, n. (type species Leptodes semenowi Reitter, 1892) is established for species which Kaszab included in Leptodes s. str. A new species, Leptodes daghestanicus G. Medvedev et Iljina, sp. n., is described from Daghestan.     

<Emphasis Type="Italic">Lobocapillaria austropacifica</Emphasis> n. g., n. sp. (Nematoda: Capillariidae) from the obtuse barracuda <Emphasis Type="Italic">Sphyraena obtusata</Emphasis> Cuvier (Sphyraenidae,Perciformes) off eastern Australia

Based on light and scanning electron microscopical studies, a new nematode parasite, Lobocapillaria austropacifica n. sp. (Capillariidae), is described from the gall-bladder of the marine fish (obtuse barracuda) Sphyraena obtusata Cuvier (Perciformes: Sphyraenidae) from off the eastern Pacific coast of Australia, for which a new genus Lobocapillaria n. g. is established. This new genus is mainly characterised by a single row of stichocytes, the presence of two large, conspicuously elongated lateral caudal lobes and a pair of subventral papillae at their base in males, a flat spicule distended laterally towards its proximal end and provided with superficial rough transverse grooves, a spicular canal and a very long, aspinose spicular sheath with a conspicuous expansion near its proximal end when evaginated. Capillaria sphyraeni Parukhin, 1971 is transferred to Lobocapillaria as L. sphyreni (Parukhin, 1971) n. comb. A key to capillariid genera containing species parasitic in fishes is provided.     

On new Jurassic Rissooidea and Zygopleuroidea convergently similar to them (Gastropoda: Pectinibranchia)

A new genus, Boreomica gen. nov., is established; it comprises small-sized gastropods widespread in the Jurassic of the Russian Plate, the taxonomic position of which was ambiguously treated by previous authors. The new genus is assigned to the family Rissoidae. The species composition and stratigraphical and geographical distribution of the genus and its species are discussed. From the Jurassic of the Russian Plate, Callovian Boreomica exigua (Gerasimov, 1992), the type species of the genus, and Kimmeridgian–Volgian Boreomica undulata (Tullberg, 1881), and members of the genus without species status from the Bathonian and Upper Oxfordian are described. Conchological polymorphism of species connected with their eurybiontic characteristics is discussed. Based on the study of samples of the species B. exigua from different types of facies, two subspecies are recognized, B. exigua exigua and B. exigua arenosa subsp. nov. Finds of gastropods morphologically similar to Boreomica are discussed: Katosira? sp. from Mitta et al., 2004, “Procerithium?” volgense Gerasimov, 1955, “Eulima” pusilla Tullberg, 1881, and “Hudlestonella” caleptra sensu Gerasimov, 1992 are considered. It is concluded that E. pusilla and H. caleptra are unknown zygopleurids, Katosira? sp. is likely a poorly preserved Katosira, and “Procerithium?” volgense is represented by a mixture of several species belonging to different genera: several zygopleurid species, the rissoids Boreomica undulata and Bralitzia. Shells of P. volgense in the P.A. Gerasimov’s collection from the Craspedites nodiger Zone are described as Laevipleura sp.     

Limacodid moths (Lepidoptera,Limacodidae) of Taiwan,with descriptions of six new species

A list of species of Limacodidae from Taiwan is given (58 species, 43 genera). Six new species are described: Calauta obscura sp. n., Ceratonema apodina sp. n., Trichogyia concava sp. n., Neiraga fulva sp. n., Sansarea formosana sp. n., and Griseothosea rufula sp. n. The species Mastumurides bicolor (Shiraki, 1913) comb. n. is transferred from the genus Thosea Walker, 1855, thus forming a new generic combination.     

Two new genera of the family Derbidae from the new world,with description of recent and an extinct miocene new species (Homoptera,Fulgoroidea)

Two new species of the family Derbidae are described. Anticedusa gen. n. (tribe Cedusini) includes the recent A. loisae sp. n. (type species) from Costa Rica and A. dominicana sp. n. from the Miocene Dominican amber. Cedochrusa gen. n. (type species Cedusa quixoa Kramer from Panama) of the tribe Cedochreini also contains a new species, Cedochrusa luculenta sp. n. from Costa Rica. A new subtribe Eocenchreina subtrib. n. comprising genera Eocenchrea Muir, Melusa Em., and Anticedusa gen. n. is erected for Cedusini with the achilid venation of the clavus.     

A new gonad-infecting species of <Emphasis Type="Italic">Philometra</Emphasis> Costa, 1845 (Nematoda: Philometridae) from the marine fish <Emphasis Type="Italic">Terapon jarbua</Emphasis> (Forsskål) (Terapontidae) off the eastern coast of India

A new nematode species, Philometra terapontis n. sp. (Philometridae), is described from male and female specimens found in the ovary of the jarbua terapon Terapon jarbua (Forsskål) (Terapontidae, Perciformes) from the Bay of Bengal off the eastern coast of India. Based on light and scanning electron microscopical examination, the new species differs from most other gonad-infecting Philometra spp. in the length of the spicules (105–114 μm), a gubernaculum with dorsal, lamella-like structures and a distinct protuberance on its distal end, and a U-shaped, dorsally uninterrupted caudal mound in the male. From a few congeneric, gonad-infecting species with unknown males, it can be distinguished by morphological and biometrical features found in gravid females (i.e. length of body, length of first-stage larvae or oesophagus, and caudal structure), by the host type (fish family) and by the geographical distribution. Philometra terapontis is the first philometrid species reported from a fish belonging to the family Terapontidae. Philometra sawara Quiazon, Yoshinaga &; Ogawa, 2008 is considered a junior synonym of P. scomberomori (Yamaguti, 1935). A key to gonad-infecting species of Philometra parasitising marine and brackish-water fishes is provided.     

Four new species of <Emphasis Type="Italic">Paradiscogaster</Emphasis> Yamaguti, 1934 (Digenea: Faustulidae) from batfishes (Perciformes: Ephippidae) on the Great Barrier Reef,Australia

Examination of three species of batfishes (Teleostei: Epphippidae) from off Lizard and Heron Islands on the Great Barrier Reef led to the discovery of specimens of the trematode genus Paradiscogaster Yamaguti, 1934 (Digenea: Faustulidae). Morphological analysis demonstrated that the new specimens represented four morphotypes which we interpret to be new species: Paradiscogaster martini n. sp., P. vichovae n. sp. and P. brayi n. sp. from Platax orbicularis (Forsskål) and P. pinnatus (Linnaeus) off Lizard Island, and P. nitschkei n. sp. from P. teira (Forsskål) off Heron Island. Published material was re-examined and the specimens identified as P. chaetodontis okinawensis Yamaguti, 1971 from P. pinnatus from Okinawa, Japan, actually represent the new species P. brayi n. sp., demonstrating that some species of Paradiscogaster have wide geographical distributions. ITS2 rDNA data for the four morphotypes differ by 4–39 base pairs confirming the delineation of the four species proposed. A feature of this study is the recognition of Platax spp. as an important host group for Paradiscogaster, with the new species placing them as the second richest host group for these parasites after the Chaetodontidae.     

Two new species of <Emphasis Type="Italic">Trouessartia</Emphasis> Canestrini, 1899 (Astigmata: Trouessartiidae) from passeriform birds in Brazil

Two new feather mite species of the genus Trouessartia Canestrini, 1899 (Analgoidea: Trouessartiidae) are described from passerines (Aves: Passeriformes) in Brazil: T. calcealgiana n. sp. from Philydor atricapillus (Wied) (Furnariidae), and T. gigaphallus n. sp. from Tyrannus melancholicus Vieillot (Tyrannidae). Both species have unique features, such as the large hook-like seta sR on trochanters III in T. calcealgiana, and the large male genitalia in T. gigaphallus, which are at least twice as long as normally found in most species of Trouessartia.     

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.
