Two new replacement names for the planthopper genera in Dictyopharidae (Hemiptera,Fulgoromorpha)

New replacement names are proposed for two genera of the family Dictyopharidae (Hemiptera: Fulgoromorpha). The following changes are proposed: Neonotostrophia nom. n. for Notostrophia Emeljanov (not Waterhouse); Emeljanovina nom. n. for Glochina Emeljanov (not Meigen); Neonotostrophia nigrosuturalis (Melichar, 1912) comb. n. from Notostrophia nigrosuturalis (Melichar, 1912) = Dictyophara nigrosuturalis Melichar, 1912 and Emeljanovina dixoni (Distant, 1906) comb. n. from Glochina dixoni (Distant, 1906) = Dictyophara dixoni Distant, 1906.

Diversity and temporal variations of the Hemiptera Auchenorrhyncha fauna in the Ajaccio region (France,Corsica)

Summary

During a one-year survey of the Auchenorrhyncha fauna in a maquis habitat of the Ajaccio region (Corsica), 37 species were listed including three alien species recorded in Europe in the last decades. The standard 658 bp mitochondrial COI barcode was obtained for 32 species, including 14 species never previously barcoded. Neighbor-joining analyses confirmed the delineation for all the species. However, comparisons with available sequences from mainland Europe showed that four species presented a significant intraspecific divergence (>3%), whereas a reduced interspecific divergence was found for another set of species. Complementary studies may therefore be necessary to better assess their taxonomic levels. Three species – Euscelis lineolata Brullé, 1832 (Cicadellidae), Philaenus spumarius (Linnaeus, 1758) (Aphrophoridae) and Latilica maculipes (Melichar, 1906) (Issidae) – accounted for up to 74.3% of the total insects collected. Although taxonomic interpretations using restricted sampling and COI sequences alone are not robust, the proportion of new sequences highlight the global lack of knowledge about the Auchenorrhyncha as a whole and the potentially presence of cryptic taxa in different clades.     

New and little known planthoppers of the subfamily Ommatidiotinae (Homoptera,Fulgoroidea, Caliscelidae) from Madagascar and South Asia

Cano merinus gen. et sp. n., belonging to the tribe Augilini Baker, is described from Madagascar. Tubilustrium typicum Distant, 1916 is transferred from the tribe Ommatidiotini Fieber to the tribe Augilini. Lasonia kirkaldyi Melichar, 1903 is transferred from the family Issidae to the family Caliscelidae, tribe Adenissini Dlabola. A key to the tribes of the subfamily Ommatidiotinae is provided.     

On the composition and distribution of the family Acanaloniidae Amyot et Serville (Homoptera, Fulgoroidea)

The composition of the family Acanaloniidae Amyot et Serville, 1843 is revised. According to the synapomorphies in the structure of the male and female genitalia, the family Acanaloniidae s. str. comprises 4 New World genera: Acanalonia Spinola, 1839, Batusa Melichar, 1901, Chlorochara Stål, 1869, and Philatis Stål, 1862. Galapagosana Distant, 1909 and Euthiscia Van Duzee, 1923 are placed in synonymy to Philatis Stål, 1862. The taxonomic position of the genera Aylaella Demir et Ozdikmen, 2009 (replacement name pro Perinetia Lallemand et Synave, 1954), Hemithiscia Schmidt, 1912, Paraphilatis Melichar, 1912, Parathiscia Melichar, 1901, Pseudothiscia Schmidt, 1912, Thinea Melichar, 1912, and Thiscia Stål, 1862 is unclear and needs further study.     

Paracorethrura Melichar, 1915 (Hemiptera: Lophopidae): two distinct species or sexual dimorphism in a species?

A taxonomic update is provided for Paracorethrura Melichar, 1915. P. arrhen n. sp. is described from Vietnam and brings up the number of species to two for the genus: P. iocnemis (Jacobi, 1905) being known only by female specimens and P. arrhen only by males, CO1 sequences are provided in order to check if they are truly two different species or if we are witnessing some sexual dimorphism.     

A new genus of Dictyopharidae (Homoptera) from Chile

Chondrophana gen. n. with the type species Cixius gayi Spinola, 1852 (= Chondrodera chilensis Melichar, 1912, syn. n.) is described from Chile. The new genus differs from Chondrodera Melichar in a short head, fully developed intermedial carinae on the metope (clearly not reaching the clypeus in Chondrodera), in the presence of granules on the humeral and pectoral areas of the prothorax and also on the lateral lobes of the metope from the apical callus to the clypeus (in Ch. granicollis, granules and also the intermedial carinae in the lower half of the metope are absent), in multidentate apices of the 1st and 2nd segment of the hind tarsus, in a petiolate ScRM, and in the pterostigma closing the anteroradial area.     

Systematic revision of Aluntiini Emeljanov, 1979 (Hemiptera: Fulgoromorpha: Dictyopharidae: Dictyopharinae): reclassification,phylogenetic analysis,and biogeography

The dictyopharid planthopper tribe Aluntiini s.l. is revised and reclassified into two tribes: Aluntiini s.s. and Arjunini Song & Szwedo trib. nov. The tribe Aluntiini s.s. includes five genera: Aluntia Stål, 1866; D endrophora Melichar, 1903 stat. rev. ; Dictyomorpha Melichar, 1912; Indodictyophara Liang & Song, 2012; and Madagascaritia Song & Liang gen. nov. The new tribe Arjunini comprises two genera – Arjuna Muir, 1934 and Pippax Emeljanov, 2008 – both moved from Aluntiini s.l. Four new species – A luntia longicephalica Song & Szwedo sp. nov. , Madagascaritia angusta Song & Liang sp. nov. , Arjuna maai Song & Wang sp. nov. , and Arjuna muiri Song & Wang sp. nov. – are described. A morphologically based phylogenetic analysis is undertaken for Aluntiini, Arjunini, and the representatives of Dictyopharini, Hastini, Orthopagini, and the fossil Worskaitini within Dictyopharinae, all distributed in the Old World. A matrix of 129 characters of the habitus, coloration, head, thorax, and male and female genitalia of the adults was used for the cladistic analysis. The phylogenetic results show that Aluntiini s.l. as placed in Dictyopharidae is well supported, but it is distinctly paraphyletic and should be separated into two unambiguous tribes. A palaeotropical distribution pattern displayed by Aluntiini is suggested. The origin and diversification of Aluntiini are discussed preliminarily. © 2015 The Linnean Society of London     

Molecular characterization of major histocompatibility complex class I genes from the giant panda (Ailuropoda melanoleuca)

The major histocompatibility complex class I genes play crucial roles in the adaptive immune system of vertebrates against intracellular pathogens. To date, no class I genes from the giant panda (Ailuropoda melanoleuca) has been reported, even none from species of Ursidae. In this study, we successfully identified three class I genes from a giant panda bacterial artificial chromosome library and designated them as Aime-128, 152, and 1906, respectively. Pairwise sequence alignments revealed that (1) the Aime-1906 always possessed the lowest identities (52–86%) in different regions compared with the Aime-128 and 152 and (2) the Aime-128 also varied from the Aime-152 in the regions of 5′ untranslated region (UTR), 3′ UTR, and exon1, whose similarities were 83%, 87%, and 91%, respectively. Comparison of structure characteristics indicated that the Aime-128 possessed all conserved amino acids important to the function of antigen presentation while the Aime-152 and 1906 presented two and five mutated residues. Analysis of phylogenetic trees demonstrated that the Aime-128, 152, and 1906 were clustered into three different branches with 99% or 100% bootstrap values. As a result, these three kinds of evidence supported that the Aime-1906, 152, and 128 should be derived from different loci. Furthermore, in view of a prestop codon in the exon 7 and patterns of amino acid replacement within alleles, the Aime-1906 gene is predicted to be a nonclassical locus, which is most closely related to dog leukocyte antigen 79 in the phylogenetic tree constructed with various mammalian class I loci.

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.     

Phylogeny of the leafhopper subfamily Evacanthinae with a review of Neotropical species and notes on related groups (Hemiptera: Membracoidea: Cicadellidae)

Abstract. The phylogenetic analysis of ninety‐two adult morphological characters supports the treatment of Nirvaninae as a junior synonym of Evacanthinae and the redefinition of Evacanthinae to include the tribes Nirvanini, Balbillini, Evacanthini and Pagaroniini. The analysis indicates that Nirvaninae, as previously defined, is polyphyletic. A key to tribes and Neotropical genera is provided and diagnostic features for these taxa are reviewed. Jassoqualus Kramer, Neonirvana Oman, Synogonia Melichar (=Jassopronus Nielson & Godoy, syn.n.) and Tahura Melichar are retained within Nirvanini and two new Neotropical genera of this tribe are described and illustrated: Antillonirvana, gen.n., based on two new species from the Dominican Republic and one from Cuba; and Chibchanirvana, gen.n., based on two new species from Colombia. Pentoffia Kramer and Evanirvana Hill are treated as incertae sedis within Evacanthinae. Six new species of Pentoffia, a new species of Synogonia, a new species of Jassoqualus, two new species of Neonirvana and eleven new species of Tahura, all from South America, are also described and illustrated. The following taxa included previously in Nirvaninae are excluded from Evacanthinae, sensu lato: Tungurahuala Kramer to Cicadellinae; Columbonirvana Linnavuori to Typhlocybinae; Macroceratogoniini to Coelidiinae; Occinirvanini Evans to Deltocephalinae. Omaranus Distant, placed previously in Occinirvanini, is transferred to Doraturini (Deltocephalinae).     

Notes on the phylogenetic relationships of planthoppers of the family issidae (Hemiptera,Fulgoroidea) of the Western Palaearctic fauna,with descriptions of two new genera

Seven groups of genera are distinguished in the subtribe Issina Spinola. The new genera Apedalmus gen. n. (the type species Falcidius abruzicus Dlabola, 1983) and Thalassana gen. n. (the type species: Hysteropterum ephialtes Linnavuori, 1971) are erected. The subgenera Acrestia Dlabola, 1980, Montissus Gnezdilov, 2003, and Atticus Gnezdilov, 2003 are upgraded to genera. The subgenus Capititudes Gnezdilov, Drosopoulos et Wilson, 2004 is transferred to the genus Acrestia, and the subgenus Stygiata Emeljanov, 1972 to Celyphoma Emeljanov, 1971. The subtribe Agalmatiina Gnezdilov, 2002 and the subfamily Hysteropterinae Melichar, 1906 are placed in synonymy under Issina Spinola, 1839. Issus reticulatus Herrich-Schäffer, 1835 is designated as the type species of the genus Hysteropterum Amyot et Serville, 1843.     

Nais pseudobtusa Piguet, 1906 (Oligochaeta: Naididae) New to Australia

Plasmid transduction in Streptococcus thermophilus

Summary Streptococcus thermophilus is a common dairy starter for which very few genetic exchange systems have been described. Here we report plasmid transduction by 17 and 56, two virulent phages of industrial yogurt starter strains. Several replicons could be transduced, independently of their size, with efficiencies which are high enough to allow gene transfer from a transformable intermediary strain of S. thermophilus to other hosts of the bacteriophages studied.     

A new tropiduchid planthopper genus and species from China with descriptions of in copula genitalic structures (Hemiptera: Fulgoromorpha)

Abstract The new planthopper taxon, Garumnella bella gen.n. , sp.n. , from Xizang, China, is described and illustrated, including external morphology of adult and eggs and structures of the male and female genitalia. The new genus is compared with Garumna Melichar and Paragarumna Muir, resulting in Paragarumna ( syn.n. ) being placed as a junior synonym of Garumna, with two new combinations, i.e. Garumna pseudolepida (Muir) comb.n. and Garumna melichari Baker comb.rev. New locality records for Garumna species are given. The morphology of the genitalia and egg of a copulating pair of the new genus is investigated. The female has a ventrally sclerotized posterior vagina forming a torsion groove, an unusual long membranous anterior vagina and an enlarged common oviduct. During copulation both the aedeagus and the torsion groove appear tightly interlocked, which may help to maintain the copulatory position. The aedeagus is observed in the bursa copulatrix.     

Reasons for cannabis use during pregnancy and lactation: a qualitative study

Background:Cannabis use among pregnant and lactating people is increasing, despite clinical evidence showing that cannabis use may be associated with low birth weight and childhood developmental deficits. Our objective was to understand why pregnant and lactating people use cannabis and how these motivations change across perinatal stages.Methods:Using qualitative, constructivist grounded theory methodology, we conducted telephone and virtual interviews with 52 individuals from across Canada. We selected participants using maximum variation and theoretical sampling. They were eligible if they had been pregnant or lactating within the past year and had decided to continue, cease or decrease their cannabis use during the perinatal period.Results:We identified 3 categories of reasons that people use cannabis during pregnancy and lactation: sensation-seeking for fun and enjoyment; symptom management of chronic conditions and conditions related to pregnancy; and coping with the unpleasant, but nonpathologized, experiences of life. Before pregnancy, participants endorsed reasons for using cannabis in these 3 categories in similar proportions, with many offering multiple reasons for use. During pregnancy, reasons for use shifted primarily to symptom management. During lactation, reasons returned to resemble those expressed before pregnancy.Interpretation:In this study, we showed that pregnant and lactating people use cannabis for many reasons, particularly for symptom management. Reasons for cannabis use changed across reproductive stages. The dynamic nature of the reasons for use across stages speaks to participant perception of benefits and risks, and perhaps a desire to cast cannabis use during pregnancy as therapeutic because of perceived stigma.

Cannabis use by pregnant and lactating people is increasing, though it is difficult to establish the prevalence of cannabis use in pregnancy. Reported prevalence varies from 2% to 36%, depending on the methodology used to detect use, the population studied and the definition of use.^1–12 Pregnant people have reported using cannabis to manage pregnancy-related conditions (e.g., nausea, weight gain, sleep difficulty)^13–19 and pre-existing conditions (e.g., mental health, insomnia, chronic pain),^13,14,18 as well as to improve mood, mental, physical and spiritual well-being,^16,18 provide pleasure and manage stress.^13–16 Recent systematic reviews have not found empirical data on reasons for cannabis use during lactation.^20,21Evidence is still emerging about clinical outcomes related to cannabis use during pregnancy and lactation, and well-controlled studies are lacking.^22–24 The available evidence is limited by reliance on self-reported data about dose, composition and timing of exposure, the changing nature of tetrahydrocannabinol levels in cannabis over time, and a lack of studies that control for known confounders such as polysubstance and tobacco use.^25–31 The available evidence does suggest that cannabis use during pregnancy may be associated with complications such as low birth weight, childhood neurodevelopmental outcomes and preterm birth.^{22–24,32,33} Very few studies have analyzed the outcomes associated with cannabis exposure through breastmilk, with 1 study suggesting decreased infant motor development and another showing no effects on developmental outcomes.^34–36 Given the potential harms identified, and in the absence of high-quality evidence available to guide practice, most clinical guidelines recommend abstinence from cannabis during pregnancy and lactation.^37–39People who perceive benefits from cannabis may wish to or may be motivated to continue using it through pregnancy and lactation, however. Counselling that explores the reasons patients are considering cannabis use and suggests related alternatives or harm reduction strategies has been identified as a helpful strategy to minimize potential harm.^13,40,41,42 Such an approach requires that clinicians understand the motivations to use cannabis before pregnancy, during pregnancy and during lactation. We sought to explore why people use cannabis during pregnancy and lactation.
