The Diplazontinae identified and described by Setsuya Momoi in the collection of Dr. Kaszab from Mongolia were examined at the Hungarian Natural History Museum in Budapest. Because of insufficient labelling, the type status of some specimens had to be clarified and four lectotypes were designated. Syrphophilus stibarus Momoi,1973 is conspecific with Syrphophilus dilleriator Aubert, 1976, syn. nov., and Syrphoctonus lipothrix (Momoi, 1973) is a junior synonym of Syrphoctonus haemorrhoidalis (Szépligeti, 1898), syn. nov. Diplazon multicolor (Gravenhorst, 1829) is removed from synonymy with Diplazon annulatus (Gravenhorst, 1829), stat. rev. A new species is described, Sussaba mongolica sp. nov., and the male of Syrphoctonus venustus (Dasch, 1964) is re-described to account for the material from Mongolia. The ultrastructure of the tyloids of three species is illustrated by scanning electron micrographs to demonstrate their large variability in the subfamily. Seven species are recorded for the first time from Mongolia, four of which are recorded for the first time from the Eastern Palaearctic. These data on the Mongolian diplazontines provide further evidence for an unusually large proportion of species of this subfamily with a multiregional distribution. Copyright © 2011. Source


A new isopod species, Eonatatolana geisingensis gen. et sp. nov., is described from Middle Jurassic shallow-water sediments of southern Germany. It shows not only the almost completely preserved dorsal morphology but, in addition, details of the cephalic appendages, the pereiopods, pleopods and uropods. The presence of ambulatory pereiopods I-VII of a wide tridentate mandibular incisor with prominently developed posteriormost tooth and a narrow frontal lamina indicates that the new species belongs to the subfamily Conilerinae of family Cirolanidae within the suborder Cymothoida. It is closer to the species of the modern genus NatatolanaBruce than to any fossil isopod hitherto described. The isopod fossil record as well as current practices of isopod taxonomy in palaeontology are discussed, and the facies distribution and fossilization of isopods is reviewed with examples from the Jurassic. © The Palaeontological Association.

The published records of jumping plant-lice from Brazil comprise 70 named species but four are erroneous or doubtful. For one species a variety has been described with uncertain status. Seven named species records are added here based on recent collections bringing the number of valid species to 73. Four new combinations are proposed: Colophorina favis (Brown & Hodkinson) (from Euphalerus), Euryconus fossiconis (Brown & Hodkinson) (from Euphalerus), Leuronota solani (Rübsaamen) (from Bactericera) and Macrocorsa beeryi (Caldwell) (from Psyllia). Additional unidentified species are recorded from the genera Auchmeriniella, Calophya, Ciriacremum, Euryconus, Isogonoceraia, Leuronota, Mastigimas, Pseudophacopteron and Livia, the last being considered a misidentification. Another 23 records concern psyllid galls which could not be attributed to any genus. The collection of psyllid galls from Brazil described by E. H. Rübsaamen was revised. The checklist provides for each species the general and Brazilian distributions as well as the host plants. Biogeographical and host plant patterns are briefly discussed. Half of the native psyllid genera are endemic to the Neotropic Region and slightly less than a third are restricted to the New World. Ten species are introduced from Australia (4), Europe (2), Asia (1) and other parts of South America (3). Fabaceae are host plants of a majority of members of the Psyllidae, whereas many Triozidae are associated with Myrtaceae. Copyright © 2012 · Magnolia Press. Source

A revised classification for the world jumping plant-lice (Hemiptera: Psylloidea) is presented comprising all published family and genus-group names. The new classification consists of eight families: Aphalaridae, Carsidaridae, Calophyidae, Homotomidae, Liviidae, Phacopteronidae, Psyllidae and Triozidae. The Aphalaridae, Liviidae and Psyllidae are redefined, 20 family-group names as well as 28 genus-group names are synonymised, and one replacement name is proposed [Sureaca nomen nov., for Acaerus Loginova, 1976]. Forty two new species combinations are proposed resulting from new genus-group synonymies and a replacement name. One subfamily and three genera are considered taxa incertae sedis, and one genus a nomen dubium. Finally eight unavailable names are listed (one family-group and seven genus-group names).

Psidium myrtoides (Myrtaceae) shelters the gall inducer Nothotrioza myrtoidis gen. et sp. n. (Hemiptera: Psylloidea) which is described and illustrated here. Nothotrioza belongs to the family Triozidae and is probably most closely related to Neolithus, a monotypic Neotropical genus associated with Sapium (Euphorbiaceae). Three species are recognized with-in Nothotrioza: the type species N. myrtoidis sp. n. associated with Psidium myrtoides, N. cattleiani sp. n. (misidentified by Butignol & Pedrosa-Macedo as Neotrioza tavaresi) with Psidium cattleianum, and N. tavaresi (Crawford) comb. n. (from Neotrioza) with an unidentified species of Malpighiaceae, respectively. A lectotype is designated here for Neotrioza tavaresi. Also, the diversity of insect galls associated with P. myrtoides and the biology of N. myrtoidis were examined. N. myrtoidis presents five instars and an annual life cycle synchronised with the phenology of P. myrtoides. Gall size was proportional to the insect developmental stages, and rates of parasitism and mortality were 15.7 % and 29.8 %, respective-ly. The red colour is an important macroscopic diagnostic feature of the gall that could be associated with parasite-free condition of the galling insect. The biological features presented by the system Psidium myrtoides - Nothotrioza myrtoidis are in accordance with other systems involving sucking galling insects, however, it is exceptional by its univoltine life cycle associated with a perennial plant in the Neotropics. The galls induced by the three known Nothotrioza spp. are mor-phologically similar, i.e. closed, globoid and unilocular, as well as the opening mechanism for releasing the adults.
