Improved tribal delimitation of the subfamily Dictyopharinae and description of new genera and new species (Homoptera,Fulgoroidea, Dictyopharidae)

Ten new genera, five new subgenera, and five new species are described in the family Dictyopharidae. Three generic names are synonymized. A new name is proposed for the generic homonym. Dictyophara kazeruna Dlabola is transferred to the genus Callodictya Melichar. The genus Sinodictya Matsumura, with the type species Sinodictya tukana Matsumura, is redescribed. A new key to the tribes of the subfamily Dictyopharinae is given. The composition and characters of the tribes Taosini and Lappidini are revised. All the genera of the subfamily Dictyopharinae are listed according to their tribal position. New records are given for some interesting species.     

A new genus of Bucephalidae Poche, 1907 (Trematoda: Digenea) for three new species infecting the yellowtail pike,Sphyraena obtusata Cuvier (Sphyraenidae), from Moreton Bay,Queensland, Australia

Three new species of the family Bucephalidae Poche, 1907 (Trematoda: Digenea) are described from the yellowtail pike, Sphyraena obtusata Cuvier (Sphyraenidae), from Moreton Bay, Queensland, Australia. The three species are morphologically consistent with the present broad concept of the genus Bucephalus Baer, 1827, but significant phylogenetic and ecological differences relative to the type-species of Bucephalus require the proposal of a new genus. Aenigmatrema n. g. is proposed for A. undecimtentaculatum n. sp. (type-species), A. inopinatum n. sp. and A. grandiovum n. sp. In addition, based on morphological, ecological and biogeographical similarities, we recombine two existing species of Bucephalus as Aenigmatrema kaku (Yamaguti, 1970) n. comb. and Aenigmatrema sphyraenae (Yamaguti, 1952) n. comb. Although the three species described in this study are extremely morphologically similar, they can be differentiated from each other, and from A. kaku and A. sphyraenae, morphometrically on the basis of egg size, tentacle number and a combination of the caecum and vitelline field lengths. Complete ITS2 rDNA, partial 28S rDNA and partial cox1 mtDNA sequence data were generated for the three new species, which formed a well-supported clade in all 28S phylogenetic analyses. An expanded phylogenetic tree for the subfamily Bucephalinae Poche, 1907 is presented, demonstrating unresolved issues with the morphology-based taxonomy of the subfamily. The three largest genera, Bucephalus, Rhipidocotyle Diesing, 1858 and Prosorhynchoides Dollfus, 1929 remain extensively polyphyletic, indicating the need for significant further systematic revision.

     

Diagnosis of Dysponetinae (Chrysopetalidae,Annelida)

The subfamily Dysponetinae (Annelida, Chrysopetalidae) was proposed by Aguado et al. (Cladistics 29, 610) based on a phylogenetic analysis including morphological and molecular information. However, as a differential diagnosis of the new subfamily, as required by the International Code of Zoological Nomenclature, was not included, the name was not made available. A diagnosis of the subfamily is proposed herein to correct this oversight.     

Phylogeny and evolution of parasitism in feather mites of the families Epidermoptidae and Dermationidae (Acari: Analgoidea)

A phylogenetic reconstruction of feather mites of the epidermoptid complex (Analgoidea: Epidermoptidae, Dermationidae, and Knemidocoptidae) was carried out by methods of parsimony-based cladistics. The epidermoptid complex splits into two major branches, Epidermoptidae and Dermationidae. The family Dermationidae is monophyletic, while the Epidermoptidae, as previously defined, is paraphyletic. The family Knemidocoptidae is reduced to the subfamilial rank because it arises from the core of the Epidermoptidae. The subfamily Myialginae Trouessart, 1906 stat. resur. is restored within the Epidermoptidae. The aberrant genera Lukoschuscoptes and Apocnemidocoptes are moved from Knemidocoptidae to Epidermoptidae and Dermationidae, respectively. A hypothesis explaining main trends in morphological and ecological adaptations to parasitism on birds within the epidermoptid complex is proposed. New taxonomic diagnoses for higher taxa (families and subfamilies) are provided, and three new genera—Archemyialges gen. n., Hemimyialges gen. n. (Epidermoptidae), and Trochiloptes gen. n. (Dermationidae)—and a new subfamily—Apocnemidocoptinae—are established.     

Molecular phylogeny of the Cyathocotylidae (Digenea,Diplostomoidea) necessitates systematic changes and reveals a history of host and environment switches

The Cyathocotylidae is a globally distributed family of digeneans parasitic as adults in fish, reptiles, birds and mammals in both freshwater and marine environments. Molecular phylogenetic analysis of interrelationships among cyathocotylids is lacking with only a few species included in previous studies. We used sequences of the nuclear 28S rRNA gene to examine phylogenetic affinities of 11 newly sequenced taxa of cyathocotylids and the closely related family Brauninidae collected from fish, reptiles, birds and dolphins from Australia, Southeast Asia, Europe, North America and South America. This is the first study to provide sequence data from adult cyathocotylids parasitic in fish and reptiles. Our analyses demonstrated that the members of the genus Braunina (family Brauninidae) belong to the Cyathocotylidae, placing the Brauninidae into synonymy with the Cyathocotylidae. In addition, our DNA sequences supported the presence of a second species in the currently monotypic Braunina. Our phylogeny revealed that Cyathocotyle spp. from crocodilians belong to a separate genus (Suchocyathocotyle, previously proposed as a subgenus) and subfamily (Suchocyathocotylinae subfam. n.). Morphological study of Gogatea serpentum indicum supported its elevation to species as Gogatea mehri. The phylogeny did not support Holostephanoides within the subfamily Cyathocotylinae; instead, Holostephanoides formed a strongly supported clade with members of the subfamily Szidatiinae (Gogatea and Neogogatea). Therefore, we transfer Holostephanoides into the Szidatiinae. DNA sequence data revealed the potential presence of cryptic species reported under the name Mesostephanus microbursa. Our phylogeny indicated at least two major host switching events in the evolutionary history of the subfamily Szidatiinae which likely resulted in the transition of these parasites from birds to fish and snakes. Likewise, the transition to dolphins by Braunina represents another major host switching event among the Cyathocotylidae. In addition, our phylogeny revealed more than a single transition between freshwater and marine environments demonstrated in our dataset by Braunina and some Mesostephanus.

Oxfordian perisphinctid ammonites from Chacay Melehué, Argentina

A significant assemblage of Oxfordian perisphinctids was collected at Chacay Melehué, Neuquén, Argentina. It is composed of well preserved specimens belonging to the family Perisphinctidae:Perisphinctes aff.promiscuus Bukowski (Perisphinctinae),Tenuisphinctes herreroduclouxi (Leanza) (Perisphinctinae), andSubvinalesphinctes pseudokranaus n. sp. andS. prophetae (Gygi & Hillebrandt) (Vinalesphinctinae). The family Ataxioceratidae is represented byLithacosphinctes aff. janus (Choffat) (Ataxioceratinae). The subfamily VinalesphinctinaeMeléndez & Myczynski, 1987 is discussed and organized into three genera:Subvinalesphinctes Wierzbowski,Vinalesphinctes Spath andCubasphinctes Judoley & Furrazola, which seems to cover the whole of the subfamily, ranging, at least, from the lowerplicatilis to the lowerbifurcatus zones, Middle Oxfordian in Cuba, part of Mexico, Chile and Argentina. The root of the subfamily is most likelyS. pseudokranaus n. sp. The paleobiogeographic affinites are mainly Tethyan, and Tethyan-Caribbean during the Middle Oxfordian.

New tribes of the superfamily Curculionoidea (Coleoptera) in Burmese amber

Two new tribes in the Curculionoidea are described as the Anchineini Poinar and Legalov, n. trib. (Ithyceridae: Carinae) and Paleocryptorhynchini Poinar and Legalov, n. trib. (Curculionidae: Erirhininae). The genus Anchineus Poinar and Brown, 2009, n. placem. is transferred from the subfamily Curculioninae of the family Curculionidae to the subfamily Carinae of the family Ithyceridae. The genus Paleocryptorhynchus Poinar, 2009, n. placem. is transferred from the subfamily Cryptorhynchinae to the subfamily Erirhininae. The placement of the genus Mesophyletis Poinar, 2006 in the family Ithyceridae was confirmed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:0C0039DD-7BC6-4A54-9282-F43C5606D68B     

An epiphyllous fungus from the Lower Cretaceous

A fungus believed to be a member of the Microthyriales is described from the English Wealden. It occurs on the shoots of an undescribed conifer resembling Frenelopsis Schenk. From the structure of the thyrothecium and the presence of an epicuticular mycelium, the fungus is classified in the family Micropeltaceae, subfamily Stomiopeltoideae, and is described under the name Stomiopeltites cretacea gen. et sp. nov. It is the earliest fossil record of the Microthyriales.     

Die Namen der Familien und Unterfamilien der Lebermoose (Hepaticopsida)

Abstract

Part I deals briefly with the application of the Code rules to family and subfamily names.

In Part II full references are given for all family and subfamily names of Hepaticopsida, some with nomenclatural or taxonomic notes added. There are three lists, each in alphabetical order: A. legitimate names (78 f., 62 subf.), B. illegitimate names (21 f., 10 subf.), and C. invalid names (only those derived from generic names; 17 f., 11 subf.); in total 116 family and 83 subfamily names. Five family names (Choneoleaceae Schust., Conocephalaceae K. Müll., Exormothecaceae K. Müll., Oxymitraceae K. Müll., Perssoniellaceae Schust.) and three subfamily names (Allisonioideae Schust., Cololejeuneoideae Herz., Odontosehismatoideae Buch) are validated by Latin diagnosis. Five subfamily names (Hygrobielloideae (Joerg.) Schust., Isotaehidoideae (Hatch.) Grolle, Makinooideae (Nakai) Grolle, Mastigophoroideae (Nees) Grolle, Pallavicinioideae (Migula) (Grolle) are proposed by change of rank, whereas five other subfamily names (Acromastigoideae Grolle, Blepharostomatoideae Grolle, Cyathodioideae Grolle, Lethocoleoideae Grolle, Notothyladoideae Grolle) are newly proposed.

Part III is a taxonomic arrangement of the hepatic families and subfamilies. For each of the five orders of Hepaticopsida the accepted families (sixty-two in total) are listed alphabetically with full synonymy : Anthocerotales (1), Marchantiales (16), Metzgeriales (8), Calobryales (2), Jungermanniales (35). The accepted subfamilies with their synonyms are added to each family.     

Alavesia Waters and Arillo–a Cretaceous‐era genus discovered extant on the Brandberg Massif,Namibia (Diptera: Atelestidae)

Two new extant species of the fossil genus Alavesia Waters & Arillo (A. brandbergensis sp.n. and A. daura sp.n. ) are described from the Brandberg Massif, Namibia. The genus is reassigned to the family Atelestidae (subfamily Atelestinae) on the basis of male terminalia (elongate gonocoxal apodemes, ventral apodemes, subapical surstylus), female terminalia (absence of tergum 10) and a three‐articled stylus. This is the first record of Atelestidae from the Afrotropical Region. A genus‐level phylogeny of the Atelestidae is resolved, in which Alavesia is the sister genus to the remaining genera of the Atelestinae. The biogeographic history of the genus is briefly discussed, as is the significance of this and other relict Diptera on the Brandberg.     

Anisoloboides joliveti n. g., n. sp. (Apicomplexa,Eugregarina, Gregarinidae), parasite of Brachyomus histrio Faust (Coleoptera,Curculionidae), with remarks on the other gregarines from the Curculionidae

The creation of a new genus of Eugregarina, Anisoloboides n. g., is proposed to accommodate the gregarines from the Curculionidae (Coleoptera) belonging to the subfamily Brachycerinae and the tribe Entimini and formerly described as Anisolobus (A. bulliardi, A. gymnopholi, A. desportis). A fourth species, A. joliveti n. sp. is described from another curculionid, Brachyomus histrio Faust, from Venezuela, and a list is presented of the other gregarines (Gregarina, Hirmocystis, Steinina) recorded from the Curculionidae.     

Turneriella nom. nov., a replacement name for the genus Amblyzancla Turner, 1939 (Lepidoptera,Yponomeutoidea)

Abstract

A replacement name, Turneriella is proposed for an Australian moth genus, the monotypic genus Amblyzancla Turner, 1939 in the family Yponomeutidae (Lepidoptera, Yponomeutoidea).     

Bucaniid gastropods from the upper Ordovician of Baltica, with a discussion of the Bucaniinae

ABSTRACT. Three species of bucaniid gastropods from the upper Ordovician of Norway and Sweden are revised: Euomphalopterus excavatus is redescribed as a species of Phragmolites with very wide umbilici and ornamentation similar to that of Offleya. Three out of five specimens from the original type series of Temnodiscus lindstroemi remain, representing two different species of two different genera. The original species name is restricted to a species of Phragmolites, whereas two specimens are considered conspecific with Megalomphala? carinata sp. nov., although the high carina, the flaring aperture and the laterally compressed whorls seen in this species are unusual for the genus. The gastropod subfamily Bucaniinae of the family Bucaniidae is here considered to comprise nine genera. Placement of Phragmolites in this family is supported by its deep slit, tangential aperture, transverse growth lines, spiral and collabral ornamentation and the presence of a longitudinal keel on the base of the whorl.     

Johanneshowellia (Polygonaceae: Eriogonoideae), a new genus from the Intermountain West

A new genus ofPolygonaceae subfam.Eriogonoideae is established for what has long been known asEriogonum puberulum. NamedJohanneshowellia in honor of the late John Thomas Howell (1903–1994), a new combination,J. puberula, and a new species,J. crateriorum, are established. The common name Howell's-buckwheat is proposed for the group. The new genus differs from other members of the subfamily in having its involucral structure reduced to a spiral of four to seven bracts each of which is associated with a flower-bearing pedicel and a basal bractlet. In bud and early anthesis the outer two (rarely outer three) bracts may be partially connate, but typically become separate at full anthesis. The connate, ternate, foliar bracts at the base of the node act as a traditionalEriogonum-like involucre surrounding the branches of the inflorescence, the involucral bracts, and the flowers. Members of the new genus are found in the arid Intermountain West of the United States from Inyo Co., California, across Nevada to western Utah.     

Catoptinae subfam. n., a new subfamily of carpenter-moths (Lepidoptera,Cossidae)

The new subfamily of Cossidae; Catoptinae Yakovlev, subfam. n., well distinguished from other representatives of the family, is described. The new subfamily includes two genera: Catopta Staudinger, 1899 (type genus) and Chiangmaiana Kemal et Koçak, 2006. A catalogue of the subfamily is presented. One new synonym Catopta hyrcanus (Christoph, 1888) = Catopta brandti Bryk, 1947, syn. n., is established. The new subfamily has the following distinguishing features: short valvae; reduced processes of transtilla; vesica with numerous cornuti; pearshaped bursa copulatrix; and very short ductus bursae.
