Parapsylla, a Gondwanan element in the psyllid fauna of southern Africa (Homoptera)

The genus Parapsylla (Homoptera: Psylloidea) is redescribed and placed in the Diaphorininae of the Family Aphalaridae. Its relationships within this subfamily are discussed. The genus Agmapsylla syn. nov. is placed into the synonymy of Parapsylla , and Pennavena syn. nov. and Eudiaphorina syn. nov. are placed into the synonymy of Diaphorina. The eight known species of Parapsylla are distributed in southern Africa and upland areas of East Africa. Host plant relationships are not clearly established but the genus appears to be associated with species of Maytenus (Celastraceae), Olinia (Oliniaceae) and possibly Olea (Oleaceae) and Syzygium (Myrtaceae). Parapsylla relicta syn. nov, and A. aureus syn. nov. are placed into the synonymy of Arytaina capensis. Parapsylla capensis comb. nov. is transferred from Arytaina, Parapsylla valens comb. nov. is transferred from Diaphorina , and the following new species are described: P. angolensis sp. nov., P. eafra sp. nov., P. huila sp. nov., P. marginipennis sp. nov., P. rufa sp. nov. and P. theroni sp. nov.     

A new genus Thubdora Park,gen. nov. and seven new species of the subfamily Torodorinae (Lepidoptera,Lecithoceridae) from Cameroon and Rep. of Congo,Africa

Based on the material collected from Cameroon in 1913–1918 and Congo in 1993 which are preserved in the Carnegie Museum of Natural History, Pittsburgh, USA, a new genus Thubdora Park, gen. nov. and seven new species of the subfamily Torodorinae (Lecithoceridae) are described. They are Torodora efulenensis sp. nov., Dragmatucha hispidula sp. nov.; and five species of Thubdora: T. acutalis sp. nov., T. bilobella sp. nov., T. aciphalla sp. nov., T. ambliodes sp. nov., and T. cameroona sp. nov. In addition, six species of Lecithocera Herrich-Shäffer described by Viette, 1955, Viette, 1986 and Meyrick, 1931, Meyrick, 1933 are newly transferred to Torodora and its related genera, due to the male genital characters: Idiopteryx adella (Viette, 1955), comb. nov.; Thubdora decavella (Viette, 1955), comb. nov.; Thubdora mocquerysella (Viette, 1955), comb. nov.; Torodora kambanella (Viette, 1986), comb. nov.; Torodora masoalella (Viette, 1955), comb. nov.; Torodora monobyrsa (Meyrick, 1931), comb. nov.; and T. ochrometra (Meyrick, 1933), comb. nov. For the new species, images of adults with their labels and genitalia are provided.     

Phylogenetic relationships in the tribe Oxyptilini (Lepidoptera,Pterophoridae, Pterophorinae) based on morphological data of adults

The monophyly of the tribe Oxyptilini and phylogenetic relationships of the genera embraced in this tribe were examined using 171 (75 binary and 96 multistate) characters of adult morphology. The study material included 98 species of 30 genera, representing all previously recognized genera of Oxyptilini, together with the genera Sphenarches, Antarches, Diacrotricha, and Cosmoclostis, four species of Oidaematophorini, three species of Platyptiliini, as well as three and two other species belonging to Pterophorini and Exelastini respectively. Two Agdistis species were used as outgroups. The cladistic analysis resulted in six equally parsimonious trees. A majority of the recovered synapomorphic characters have previously been used in the taxonomy of the subfamily. However, 25 novel characters were found. The monophyly of Oxyptilini was supported, although only with homoplastic characters and low amounts of tree confidence; the genera Capperia, Procapperia, Paracapperia, Oxyptilus, Megalorhipida, and Trichoptilus were found to be nonmonophyletic; Sphenarches and Antarches were recovered as members of Oxyptilini; the two genera Cosmoclostis and Diacrotricha were placed out of Oxyptilini, inside the tribe Pterophorini; and close affinity of the genus Dejongia to Stangeia, Stenodacma, Megalorhipida, Trichoptilus, and Buckleria species was revealed. Four new combinations, Cosmoclostis lanceata (Arenberger) comb. nov. , Nippoptilia regulus (Meyrick) comb. nov. , Capperia tadzhica (Zagulajev) comb. nov. , and Buckleria negotiosus (Meyrick) comb. nov. are proposed; Capperia insomnis Townsend was considered as a senior synonym of Procapperia hackeri Arenberger syn. nov. , Buckleria negotiosus (Meyrick) as a senior synonym of Buckleria vanderwolfi Gielis syn. nov. , and Oxyptilus variegatus Meyrick syn. nov. as a junior synonym of Oxyptilus secutor Meyrick. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163 , 484–547.     

JURASSIC PALAEONTINIDAE FROM CHINA AND THE HIGHER SYSTEMATICS OF PALAEONTINOIDEA (INSECTA: HEMIPTERA: CICADOMORPHA)

Abstract:  Genera of Palaeontinidae (Insecta, Hemiptera: Cicadomorpha) are reviewed based on some newly-discovered material. An updated list of palaeontinid genera is provided. The genus Palaeontinopsis Martynov is assigned to Palaeontinidae incertae sedis . A new genus and species, Ningchengia aspera gen. et sp. nov., is described based on forewings and hindwings from the Middle Jurassic of Daohugou, China. Fletcheriana colorata Wang, Zhang and Fang and F . minuta Wang, Zhang and Fang are transferred to Suljuktocossus and Ningchengia respectively, resulting in Suljuktocossus coloratus comb. nov. and Ningchengia minuta comb. nov. Papilioncossus Wang, Ren and Shih, 2007 syn. nov. is considered to be a junior synonym of Eoiocossus Wang and Zhang, 2006 and Quadraticossus Wang and Ren 2007 syn. nov. is a junior synonym of Sinopalaeocossus   Hong, 1983 . The genus Fletcheriana is believed to represent a transition between Dunstaniidae and Palaeontinidae. This result is consistent with the previous view that Dunstaniidae is ancestral to Palaeontinidae. Furthermore, Suljuktocossus is a transitional genus between Fletcheriana and Cretaceous palaeontinids. The fusion of veins RP and M₁ in the palaeontinid hindwings implies a change of the mechanism of flight and an improvement in flight ability. The presence of a reduced costal area and the rigid basal leading edge of the palaeontinid forewings suggest gain of lift.

Jumping plant lice (Homoptera: Psylloidea) of the temperate neotropical region. Part 1: Psyllidae (subfamilies Aphalarinae, Rhinocolinae and Aphalaroidinae)

The psyllid-fauna of temperate and subantarctic South America comprises members of three families: Calophyidae, Triozidae and Psyllidae. Three subfamilies of the Psyllidae are revised in this paper: the Aphalarinae are represented by two species in two genera, one of which develops on Aquifoliaceae; the Rhinocolinae are represented by two congeneric species on Anacardiaceae while the Aphalaroidinae contain 38 species in seven genera trophically linked to the Compositae, Euphorbiaceae, Leguminosae, Myzodendraceae, Rhamnaceae, Solanaceae and Zygophyllaceae. The family Psyllidae (= Aphalaridae syn. nov. , =Spondyliaspididae syn. nov. ) and the constituent subfamily Aphalaroidinae (= Arepuninae syn nov. , = Ciriacreminae auct. pp) are redefined. Three genera and 30 species are described as new and two new generic, two new specific synonyms, and five new combinations are proposed. Information on larvae and host plant relationships is also given. Lectotypes are designated for eight species and a type-species is fixed for one genus. Keys are provided for the identification to species.     

Systematic revision of Hoggicosa Roewer, 1960, the Australian ‘bicolor’ group of wolf spiders (Araneae: Lycosidae)

The Australian wolf spider genus Hoggicosa Roewer, 1960 with the type species Hoggicosa errans (Hogg, 1905) is revised to include ten species: Hoggicosa alfi sp. nov. ; Hoggicosa castanea (Hogg, 1905) comb. nov. (= Lycosa errans Hogg, 1905 syn. nov. ; = Lycosa perinflata Pulleine, 1922 syn. nov. ; = Lycosa skeeti Pulleine, 1922 syn. nov. ); Hoggicosa bicolor (McKay, 1973) comb. nov. ; Hoggicosa brennani sp. nov. ; Hoggicosa duracki (McKay, 1975) comb. nov. ; Hoggicosa forresti (McKay, 1973) comb. nov. ; Hoggicosa natashae sp. nov. ; Hoggicosa snelli (McKay, 1975) comb. nov. ; Hoggicosa storri (McKay, 1973) comb. nov. ; and Hoggicosa wolodymyri sp. nov. The Namibian Hoggicosa exigua Roewer, 1960 is transferred to Hogna, Hogna exigua (Roewer, 1960) comb. nov. A phylogenetic analysis including nine Hoggicosa species, 11 lycosine species from Australia and four from overseas, with Arctosa cinerea Fabricius, 1777 as outgroup, supported the monophyly of Hoggicosa, with a larger distance between the epigynum anterior pockets compared to the width of the posterior transverse part. The analysis found that an unusual sexual dimorphism for wolf spiders (females more colourful than males), evident in four species of Hoggicosa, has evolved multiple times. Hoggicosa are burrowing lycosids, several constructing doors from sand or debris, and are predominantly found in semi‐arid to arid regions of Australia. © 2010 The Linnean Society of London, Zoological Journal of the Linnean Society, 2010, 158 , 83–123.     

Synonymy of Plotococcus Miller & Denno with Leptococcus Reyne, and description of a new species from Colombia (Hemiptera: Pseudococcidae)

Plotococcus Miller & Denno is synonymized with Leptococcus Reyne (Coccoidea: Pseudococcidae). The genus is redescribed and the adult female of the type species, L. metroxyli Reyne, is redescribed and illustrated.

A new species of Leptococcus, L. rodmani Kondo sp. n., from leaves of Guarea guidonia (Meliaceae) from Colombia, is described and illustrated based on the adult female. A revised key to adult females of all species in the genus is provided.     

SULCOPYRENULA,A NEW PYRENOCARPOUS LICHEN GENUS (PYRENULACEAE,LICHENIZED ASCOMYCOTA)

Sulcopyrenula H. Harada gen. nov. is described. It differs from other genera ofPyrenulaceae by having longitudinally sulcate spores. The genus is represented by two species: S. canellae-albae (Fée) H. Harada comb. nov. and S. staurospora (Tuck.) H. Harada comb. nov. Both species have been previously reported from N. and S. America, and the latter species is now reported from Asia.     

Scabropezia, a new genus of Pezizaceae (Pezizales)

Scabropezia gen. nov., with globose spores, is described with two species, viz. the type species S. scabrosa (Cooke) comb, nov., and S. flavovirens (Fuck.) comb. nov. The relationship to the globose–spored genera Plicaria Fuck, emend. Boud. and Pachyphloeus Tul. and to the genus Peziza L. ex St.–Amans is discussed. A key for the treated taxa is provided.     

Molecular taxonomic position of the elephant schistosome, Bivitellobilharzia nairi, newly discovered in Sri Lanka

Bivitellobilharzia nairi (Mudaliar and Ramanujachar, 1945) Dutt and Srivastava, 1955 was first recorded in India. A number of adult worm specimens of this schistosome species were recovered from a domestic elephant, which died in 1999 in Sri Lanka. This is the first report of this schistosome from Sri Lanka. In the present study, in order to clarify the phylogenetic relationship with other species of schistosomes, sequences from the second internal transcribed spacer (ITS2) of the ribosomal gene repeat, part of the 28S ribosomal RNA gene (28S), and part of the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene from B. nairi were analyzed. Two intraspecific variations were seen within 13 individuals in the ITS2 region. In the CO1 region of the mitochondrial DNA, there were four haplotypes in the nucleotide sequences and two haplotypes in the amino acid sequences. Phylogenetic analysis using the nuclear DNA showed that B. nairi was basal to all of species of the genus Schistosoma. The 28S tree also showed that the mammalian lineage was monophyletic. However, phylogenetic analysis using the mitochondrial DNA showed that B. nairi was nested within the genus Schistosoma. The taxonomical position for this species as well as the contradiction between the results from the nuclear and mitochondrial genes were discussed.     

Crusticorallina gen. nov., a nongeniculate genus in the subfamily Corallinoideae (Corallinales,Rhodophyta)

Molecular phylogenetic analyses of 18S rDNA (SSU) gene sequences confirm the placement of Crusticorallina gen. nov. in Corallinoideae, the first nongeniculate genus in an otherwise geniculate subfamily. Crusticorallina is distinguished from all other coralline genera by the following suite of morpho‐anatomical characters: (i) sunken, uniporate gametangial and bi/tetrasporangial conceptacles, (ii) cells linked by cell fusions, not secondary pit connections, (iii) an epithallus of 1 or 2 cell layers, (iv) a hypothallus that occupies 50% or more of the total thallus thickness, (v) elongate meristematic cells, and (vi) trichocytes absent. Four species are recognized based on rbcL, psbA and COI‐5P sequences, C. painei sp. nov., the generitype, C. adhaerens sp. nov., C. nootkana sp. nov. and C. muricata comb. nov., previously known as Pseudolithophyllum muricatum. Type material of Lithophyllum muricatum, basionym of C. muricata, in TRH comprises at least two taxa, and therefore we accept the previously designated lectotype specimen in UC that we sequenced to confirm its identity. Crusticorallina species are very difficult to distinguish using morpho‐anatomical and/or habitat characters, although at specific sites, some species may be distinguished by a combination of morpho‐anatomy, habitat and biogeography. The Northeast Pacific now boasts six coralline endemic genera, far more than any other region of the world.

On the phylogeny of Euryteinae (Crustacea,Copepoda, Cyclopoida), with description of one new species from Korea

Euryte koreana sp. nov. is described from the shallow littoral on the East Coast of South Korea, and represents the first record of the subfamily Euryteinae Monchenko, 1974 in the Pacific Ocean north of the tropics. It belongs to a group of species that have the caudal rami length/width ratio of around four, but differs from all congeners by a number of morphological features. Detailed drawings and extensive scanning electron micrographs of many characters of ornamentation provided for this species should serve as a benchmark for distinguishing closely related species in this subfamily with conservative macro-morphology. A morphologically distinct population from anchialine caves in Mallorca, identified previously as Euryte longicauda Philippi, 1843, is described as another new species: Euryte jaumei sp. nov. To test the phylogenetic relationships of its members and previous hypotheses about generic placement of two species associated with scleractinian corals, several cladistic analyses are performed on all 16 currently recognized species of Euryteinae and two outgroups, Neocyclops australiensis Karanovic, 2008 and Troglocyclops janstocki Rocha and Iliffe, 1994, using 25 morphological characters. All resulting trees suggest a close relationship between the two commensal species and them as a sister clade to all other Euryteinae. They are transferred into a newly erected genus Coraleuryte gen. nov., as C. bellatula (Humes, 1991) comb. nov. and C. verecunda (Humes, 1992) comb. nov., and a revised diagnoses is provided for the genus Euryte Philippi, 1843. Obtained cladograms also show that Ancheuryte Herbst, 1989 is nested deeply within the Euryte clade, so the genus is synonymized and its only species is transferred, as E. notabilis (Herbst, 1989) comb. nov. A key to species of Euryteinae is also provided.     

A molecular assessment of species diversity and generic boundaries in the red algal tribes Polysiphonieae and Streblocladieae (Rhodomelaceae,Rhodophyta) in Canada

Sequence data generated during a Canadian barcode survey (COI-5P) of the tribes Polysiphonieae and Streblocladieae, a large and taxonomically challenging group of red algae, revealed significant taxonomic confusion and hidden species diversity. Polysiphonia pacifica Hollenberg, P. paniculata Montagne, P. stricta (Dillwyn) Greville and Vertebrata fucoides (Hudson) Kuntze were all complexes of two or more genetically distinct yet overlooked species. One variety of P. pacifica was elevated to the rank of species as P. determinata (Hollenberg) Savoie & Saunders, stat. nov. Several new additions to the Canadian flora were recorded including P. kapraunii Stuercke & Freshwater and P. morrowii Harvey. Subsequent multi-gene (COI-5P, LSU and rbcL) phylogenetic analyses confirmed that the genus Polysiphonia Greville was polyphyletic, and currently assigned species resolved with many other genera. Polysiphonia sensu stricto was restricted to a group of species that formed a monophyletic lineage with the type, Polysiphonia stricta. Carradoriella P.C.Silva was resurrected based on the South African species Carradoriella virgata (C.Agardh) P.C.Silva. Species previously attributed to Polysiphonia were transferred to Carradoriella, Leptosiphonia and Vertebrata as well as to three new genera described here: Acanthosiphonia gen. nov., based on A. echinata (Harvey) comb. nov.; Eutrichosiphonia gen. nov. for E. confusa (Hollenberg) comb. nov. and E. sabulosia (B.Kim & M.S.Kim) comb. nov.; and Kapraunia gen. nov., which includes K. schneideri (Stuercke & Freshwater) comb. nov. and three additional species.     

First phylogenetic analysis of the tribe Oligaphorurini (Collembola: Onychiuridae) inferred from morphological data,with implications for generic classification

Oligaphorurini represent tribe of the subfamily Onychiurinae, which currently comprises 5 genera and 53 species. The present study evaluated the monophyly of Oligaphorurini genera. We investigated phylogenetic relationships among 39 species, representing all extant genera of Oligaphorurini. Both equal- and implied-weighting parsimony analyses were used in phylogenetic reconstruction. The cladistic analyses were based on comprehensive survey of adults’ morphological characters because specimens suitable for molecular studies were not available for the majority taxa. The phylogenetic analysis resulted in the recognition of a monophyletic Chribellphorura, and strongly supported non-monophyly of the previously recognized genera Archaphorura, Dimorphaphorura, Micraphorura, and Oligaphorura. The following new synonymy is recognized: Oligaphorura = Dimorphaphorura syn. nov., = Micraphorura syn. nov., = Archaphorura syn. nov. The general classification of Oligaphorurini is followed by the diagnoses of genera and key to the all known species.
