A new genus of the family dictyopharidae (Homoptera) from Argentina

A new monotypical genus with a new species, Phormotegus lenociniosus gen. et sp. n., is described from Argentina. The new genus is closely related to the genera Taosa Distant and Brachytaosa Muir, but differs from them in the reticulate venation of the submacropterous fore wings with outcurved apices and in the unique position of the hind wings projecting laterally from the apices of the fore wings.     

A new cave-inhabiting Ptomaphaginus beetle from Sarawak (Leiodidae: Cholevinae)

Abstract. A new troglophilic species, Ptomaphaginus chapmani , is described from caves in Sarawak. it has the very unusual combination of very reduced eyes but functiobnal wings and may be interpreted as a phylogenetic relict, with characters suggesting a New World origin for this Oriental genus.     

Approaches to the structural modelling of insect wings

Insect wings lack internal muscles, and the orderly, necessary deformations which they undergo in flight and folding are in part remotely controlled, in part encoded in their structure. This factor is crucial in understanding their complex, extremely varied morphology. Models have proved particularly useful in clarifying the facilitation and control of wing deformation. Their development has followed a logical sequence from conceptual models through physical and simple analytical to numerical models. All have value provided their limitations are realized and constant comparisons made with the properties and mechanical behaviour of real wings. Numerical modelling by the finite element method is by far the most time-consuming approach, but has real potential in analysing the adaptive significance of structural details and interpreting evolutionary trends. Published examples are used to review the strengths and weaknesses of each category of model, and a summary is given of new work using finite element modelling to investigate the vibration properties and response to impact of hawkmoth wings.     

A remarkable new genus of Atalophlebiinae (Ephemeroptera: Leptophlebiidae) from the Neotropics

An unusual species of Leptophlebiidae is described based on males, females, and nymphs from Rio de Janeiro State, Brazil. As a consequence of its distinct characteristics on all stages, a new genus is established. The new genus can be distinguished from other South American Leptophlebiid genera mostly by: Adults: vein MA of fore wings asymmetrical; hind wings with costal projection well developed, Sc ending at cross vein near costal projection; tarsal claws dissimilar, one blunt other acute; projections of styliger plate forming two well developed lobes with rounded apex, ventrally obstructing view of the penes; penes fused on basal half, each lobe with a ventral furrow and a long and slender spine directed anteriorly. Nymphs: Head prognathous, wider than labrum; labrum with prominent median emargination, with three subtle crenulations; body flattened; hind wings pads present; tarsal claws with over 20 denticles, subapical denticle much larger than remaining denticles; gills long and narrow, present on abdominal segments I-VII; posterolateral projections present on abdominal segments VIII-IX. Phylogenetic analyses conducted based on a previously published data matrix that included other South America leptophlebiid genera placed Poranga nessimiani gen. nov. et sp. nov. as sister to Bessierus + Perissophlebioides. In most analyses this clade was recovered within the Farrodes complex. Nymphs of the new taxa are particularly similar to Bessierus, whereas adults share the very acute costal projection on hind wings seen in non-dipterous members of the Farrodes complex.     

Proptychopterina (Diptera: Eoptychopteridae) from the Jurassic of Northeastern China

A complete well-preserved male fly from the Jurassic of Daohugou locality (Northeastern China) is described as Proptychopterina opinata sp. nov. The distribution of Proptychopterina is discussed, this genus is re-diagnosed, and a key to species is provided based on the wings.     

尖唇叶蜂属系统分类研究(膜翅目:叶蜂科)

尖唇叶蜂属Adamas Malaise是中国新记录属。本文记述1个中国新记录种：宽缘尖唇叶蜂Adamas jakowleffi(Konow,1897)和4个新种：黄尾尖唇叶蜂A.caudatus sp.nov.,平行尖唇叶蜂A.parallelus sp.nov.,徐氏尖唇叶蜂A.xuisp.nov.和吕氏尖唇叶蜂A.lui sp.nov.,给出了详细描述和形态特征图,并编制了分种检索表。详细讨论了尖唇叶蜂属的系统学地位,初步分析了6个已知种之间的关系,认为A.jakowleffi(Konow)和A.ermak Zhelochovtsev,A.caudatus和A.parallelus.A.xui和A.lui分别构成一对姊妹种关系。尖唇叶蜂属上颚不对称,左上颚具1个大型基齿,右上颚单齿,唇基缺口深,侧叶尖,前翅臀室具很短的倾斜横脉,前胸侧板腹侧接触面窄或无,后胸后背板中央甚狭,后足基跗节很短等,表明本属是平背叶蜂亚科成员,系统学地位介于Allantini族和Empriini族之间,并自成一族——尖唇叶蜂族Adamasini。     

A remarkable new genus of Procercopidae (Hemiptera: Cercopoidea) from the Middle Jurassic of China

A new subfamily of the grasshopper (Orthoptera: Acridoidea: Gomphoceridae) from the Tibetan Plateau of China

Abstract This paper reports a new subfamily, a new genus and a new species, that is, Pacrinae subfam. nov., Pacris gen. nov and Pacris xizangensis sp. nov in Gomphoceridae. The new subfamily is allied to Orinhippinae of Gomphoceridae and it differs from the latter by wings and tympanum absent. The new genus is similar to Orinhippus Uvarov, 1921 but differs from the latter in: (i) foveolae absent; (ii) tegmina absent; (iii) tympanum absent; (iv) hind margin of pronotum with incised in the middle. Type specimens are deposited in the Museum of Hebei University, Baoding, China.     

The Sharpshooter Genus Geitogonalia Young: Descriptions of a New Brazilian Species and of the Female of Geitogonalia quatuordecimmaculata (Taschenberg) (Hemiptera: Cicadellidae)

The sharpshooter genus Geitogonalia Young was so far known from a single species from Southeastern Brasil—Geitogonalia quatuordecimmaculata (Taschenberg). A new species, Geitogonalia viridis, is described and illustrated in this paper based on males and females from the state of Rio de Janeiro. In addition, the female of G. quatuordecimmaculata is for the first time described and illustrated in detail. Geitogonalia quatuordecimmaculata is a dark species marked with bright orange on the fore wings, whereas the new species has the corium and clavus of the fore wings mostly green. The paraphyses are well developed in G. quatuordecimmaculata, with elongate rami, whereas they are inconspicuous in G. viridis, with the rami modified as a pair of very small sclerites.
