A new species of Rhopalosiphum (Hemiptera, Aphididae) on Chusquea tomentosa (Poaceae, Bambusoideae) from Costa Rica

The new species Rhopalosiphum chusqueae Pérez Hidalgo & Villalobos Muller, is described from apterous viviparous females caught on Chusquea tomentosa in Cerro de la Muerte (Costa Rica). The identity of the species is supported both by the morphological features and by a molecular phylogenetic analysis based on a fragment of the mitochondrial DNA containing the 5' region of the cytochrome c oxidase 1 (COI) and on the nuclear gene coding for the Elongation factor-1 alpha (EF1α). The taxonomic position of the new species is discussed. An identification key to the Aphidinae species living on plants of Bambusoideae (Poaceae) is presented.

Host plants are reviewed and an identification key to species is presented for six Uroleucon (Uromelan) species from the Korean Peninsula.     

Taxonomic note on the genus Taiwanocantharis Wittmer: synonym,new species and additional faunistic records from China (Coleoptera,Cantharidae)

Taiwanocantharis thibetanomima (Wittmer, 1997) is redefined and its type series is clarified. Three new speciesare described and illustrated, Taiwanocantharis wittmerisp. n. (CHINA: Yunnan), Taiwanocantharis adentatasp. n. (CHINA: Gansu, Sichuan) and Taiwanocantharis parasatoisp. n. (CHINA: Guangxi). Taiwanocantharis gansosichuana (Kazantsev, 2010) is synonymized with Taiwanocantharis drahuska (Švihla, 2004). Taiwanocantharis dedicata (Švihla, 2005) and Taiwanocantharis malaisei (Wittmer, 1989) are recorded to China for the first time.

A new species of Atheroides Haliday (Hemiptera,Aphididae) native to North America

We report and describe the first species of Atheroides Haliday presumed to be native to North America, collected at the Valles Caldera National Preserve, New Mexico, USA. We hypothesize its placement among the Siphini based on morphological, phylogenetic analysis and extend the distribution of the genus to the Holoarctic. We expand the key of the known Atheroides to include the new species and discuss the current hypotheses of the geographic distribution of the type species, Atheroides serrulatus Haliday.     

First record of the adventive oriental aphid Schizaphis piricola (Matsumura, 1917) (Hemiptera, Aphididae) in Europe

The oriental aphid Schizaphis piricola (Matsumura) is recorded for the first time in Europe, on the ornamental pear tree Pyrus calleryana in landscaped areas in Madrid (Spain). Data on the morphology of the forms on primary host (apterous and alate fundatrigeniae and fundatrices), and their biology and distribution are given. The keys for identifying species of Schizaphis (Schizaphis) in the Iberian Peninsula are updated. Two species of aphids are also recorded for the first time on Pyrus calleryana: Schizaphis piricola and Aphis pomi.     

Virulence of Hypocreales fungi to pecan aphids (Hemiptera: Aphididae) in the laboratory

There is need for efficacious biocontrol agents for aphids in commercial orchards. As a preliminary step to this end we determined the virulence of several Hypocreales fungi to pecan aphids. In the first experiment we tested the virulence of Isaria fumosorosea (ARSEF 3581) blastospores to three pecan aphids Monellia caryella, Melanocallis caryaefoliae, and Monelliopsis pecanis under laboratory conditions. Rates of 1 × 10⁷ or 1 × 10⁸ spores per ml were applied in 2 ml via a spray tower to 90 mm Petri dishes containing 10 aphids each. Mortality and mycosis were determined after 24, 48 and 72 h. Treatment effects were observed by 48 h post-application, and by 72 h the higher application rate caused >90% mortality and mycosis in M. caryella and M. caryaefoliae, whereas <70% was observed in M. pecanis.We conducted two subsequent experiments (Experiments 2 and 3), using the same methodology, to compare the virulence of several Hypocreales species and strains against the aphid of primary economic concern to most pecan growers, M. caryaefoliae. In Experiment 2, we compared blastospores and conidia of two I. fumosorosea strains (ARSEF 3581 and ATCC 20874 [= strain 97]). The blastospores of ARSEF 3581 and conidia of ATCC 20874 showed higher virulence than other treatments and thus were included in Experiment 3, which also compared the virulence of conidia of Beauveria bassiana (GHA strain) and Metarhizium anisopliae (F52 strain). Results in Experiment 3 indicated the highest virulence in I. fumosorosea 3581 blastospores and M. anisopliae (F52) followed by I. fumosorosea (20874) conidia. The detection of pathogenicity to pecan aphids establishes the potential for commercial usage and additional study. Results reported here will narrow treatments to test in future greenhouse and field trials.     

Three new species of the leafhopper genus Tautoneura Anufriev (Hemiptera, Cicadellidae, Typhlocybinae) from China

In the present paper, three new species are added to the genus Tautoneura Anufriev from China, Tautoneura baiyunshanasp. n., Tautoneura caoisp. n. and Tautoneura yunnanensissp. n. A key to species recorded from China is provided.     

Taxonomic revision of the East Asian genus Scleropteroides Colonnelli, 1979 (Coleoptera,Curculionidae, Ceutorhynchinae)

The genus Scleropteroides Colonnelli, 1979 (Ceutorhynchinae: Scleropterini) was revised on the basis of detailed morphological observations. The genus was redefined to include three species from East Asia: S. hypocrita (Hustache, 1916) is redescribed and recorded from northeastern China and northern Korea for the first time; S. horridulus (Voss, 1958) is redescribed with new records from southern Korea; S. insularis Voss, 1971 was moved from synonymy with S. hypocrita to that with S. horridulus (syn. n.), and S. longiprocessus Huang & Yoshitake, sp. n. is described as new, sympatric with S. hypocrita in Japan. All the species are associated with woody Rubus species (Rosaceae). A key to species, habitus photographs, illustrations of important characters, and distribution maps are provided for each species.     

Taxonomic revision and phylogenetic position of Osteocephalus festae (Anura, Hylidae) with description of its larva

Osteocephalus festae is an Amazonian species recently resurrected from a synonymy with Osteocephalus buckleyi. Because few specimens are known, its morphological variation, diagnostic characters, and distribution are poorly understood. Herein we determine its phylogenetic relationships and provide a complete taxonomic account based on recently collected specimens (adults and larvae) from nine localities in Ecuador and Peru. Osteocephalus festae is most similar to Osteocephalus verruciger from which it differs in having less tuberculate dorsal skin on males, smaller tympanum, and more tooth rows in the oral disk of larvae. A phylogeny based on mitochondrial DNA sequences, genes 12S and ND1, shows that Osteocephalus festae is closely related to Osteocephalus buckleyi, Osteocephalus mutabor and Osteocephalus verruciger. A clade consisting of Osteocephalus festae, Osteocephalus verruciger, and Osteocephalus buckleyi is characterized by stream dwelling tadpoles. Surprisingly, we found paraphyly among Ecuadorian populations of Osteocephalus buckleyi and Osteocephalus verruciger. The causes for paraphyly are unknown but in Osteocephalus buckleyi may result from the existence of cryptic species.     

Two more new species of Aphidura (Hemiptera,Aphididae), and a note on variation in Aphidura bozhkoae Narzikulov

Two new species of Aphidura Hille Ris Lambers, 1956 (Hemiptera, Aphididae, Macrosiphini) are described; Aphidura libanensissp. n. from Prunus prostrata in Lebanon, and Aphidura corsicensissp. n. from Cerastium soleirolii in Corsica (France). Studies of Aphidura bozhkoae specimens from different localities have revealed that this species varies in its pattern of dorsal sclerotisation and other morphological characters, within and between populations. An updated key for identifying the world’s species of Aphidura is presented.
