Morphology and ultrastructure of the alimentary canal of the cicada Platypleura kaempferi (Hemiptera: Cicadidae)

The alimentary canal of cicada Platypleura kaempferi is described. It comprises the oesophagus, filter chamber, external midgut section and hindgut. The elongate oesophagus expands posteriorly, with its posterior end constricting to become a bulb. The filter chamber consists of two parts: a very thin sheath and a filter organ. The filter organ is composed of the anterior and posterior ends of the midgut (internal midgut section), and the internal proximal ends of the Malpighian tubules. The external midgut section differentiates into a collapsed sac and a midgut loop. The latter is divided into three distinct segments. The hindgut contains a dilated rectum and a long narrow ileum. The distal portions of the four Malpighian tubules are enclosed in a peritoneal sheath together with the distal ileum before reaching to the rectum. Ultrastructurally, the oesophagus and the hindgut are lined with a cuticle. The filter chamber sheath consists of cells with large irregular nuclei. Filamentous substances coat the microvilli of the cells of the internal midgut section. The posterior end of the midgut comprises two types of cells, with the first type of cells containing many vesicles and scattered elements of rough endoplasmic reticulum. The anterior and posterior segments of the midgut loop cells have ferritin‐like granules. The ileum cells have well‐developed apical leaflets associated with mitochondria. Accumulations of virus‐like particles enclosed in the membrane are observed in the esophagus, conical segment, mid‐ and posterior segments of the midgut loop.

The genus Arctorthezia Cockerell (Hemiptera,Ortheziidae) with the description of a new species

This paper describes a new species of Arctorthezia Cockerell (Hemiptera: Coccoidea: Ortheziidae) from the Palaearctic region. The specimens were extracted from forest litter in the collections of Muséum d’histoire Naturelle de Genève, Switzerland, using Berlese funnels. Three further species, Arctorthezia cataphracta (Olafsen), Arctorthezia occidentalis (Douglas) and Arctorthezia pseudoccidentalis Morrison, are redescribed and re-illustrated. The genus Arctorthezia now contains five species. An identification key, diagnostic illustrations, photographs of unmounted females and new locality records of the Arctorthezia species currently known are provided.     

Review of Chinese species of the leafhopper genus Scaphoidella Vilbaste, 1968 (Hemiptera,Cicadellidae, Deltocephalinae), with description of a new species

The Chinese leafhopper species of the genus Scaphoidella Vilbaste are reviewed, and one new species Scaphoidella dietrichi sp. n. is described and illustrated. Two species are recorded from China for the first time: Scaphoidella clavatella Dai & Dietrich, 2011 and Scaphoidella zhangi (Viraktamath & Mohan, 2004). A key based on the male genitalia is given to distinguish Chinese species of this genus and a map provided their geographic distribution. The type specimens of the new species is deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).

A review of the genus Strophidon (Anguilliformes: Muraenidae), with description of a new species

Strophidon McClelland is a muraenid genus with characteristic appearance of a very elongated body, a large mouth cleft and anteriorly placed eyes. The nomenclature and taxonomic history of species within Strophidon are contentious and its members are easily misidentified. In the present study, species of the genus Strophidon are revised based on morphological and molecular data, and five species are considered valid, including S. dawydoffi Prokofiev, S. dorsalis (Seale), S. sathete (Hamilton), S. ui Tanaka and a new species, S. tetraporus. Strophidon tetraporus sp. nov. is described based on 15 specimens from Indonesia, the Philippines, Taiwan and Vietnam with the unique characteristic of the constant presence of the fourth infraorbital pore among species of Strophidon. The intraspecific variation of vertebral formula within S. dorsalis is discussed based on molecular data. Muraena macrurus Bleeker and Thyrsoidea longissima Kaup are synonyms of S. sathete that can be distinguished from the most similar congener S. ui by a longer tail, smaller eyes and more inner maxillary and inner dentary teeth. A key to identify species of Strophidon is provided. The distribution and maximum size of each species are also re-evaluated.

Molecular phylogeny of the genus Tibicina (Hemiptera, Cicadidae): rapid radiation and acoustic behaviour

To estimate the potential contribution of ethological and ecological parameters to the mechanisms of species formation and species isolation in the Palearctic cicada genus Tibicina , we constructed a molecular phylogenetic hypothesis of extant Tibicina species. Seven mitochondrial genes and a fragment of a nuclear gene were sequenced (3046 bp). Mitochondrial genes included 547 informative sites but the nuclear gene was too conserved to be included in the analysis. The tree was characterized by a basal polytomy indicating that Tibicina species arose rapidly. Such rapid radiation might explain the low divergence in the acoustic communication observed between species. Parameters describing habitat selection and acoustic communication were mapped onto the tree. A shift in habitat selection accompanied by acoustic changes might have contributed to one speciation event. The stochastic distribution of the same acoustic characters on the other branches of the tree implies, however, that the subtle acoustic differences between species could be the result of previous speciation events and independent evolutionary histories, rather than having contributed themselves in the speciation and isolation processes.  © 2007 The Linnean Society of London, Biological Journal of the Linnean Society , 2007, 91 , 611–626.

Review of the oriental leafhopper genus Lampridius (Hemiptera: Cicadellidae: Deltocephalinae), with description of a related new genus

The leafhopper genus Lampridius Distant, 1918 (type species: L. spectabilis Distant, 1918 ) is redescribed, and a second species, L. cuspidatus sp. nov. (Thailand: Loei), is described. A related new genus Paralampridius gen. nov. and four new species are described: P. mimicus sp. nov. (China: Guangdong, Hainan), P. rotundatus sp. nov. (Thailand: Loei), P. sinuatus sp. nov. (Thailand: Loei, Suphanburi, Petchaburi), and P. truncatus sp. nov. (Thailand: Chaiyaphum, Ubon Ratchathani). Both genera are tentatively included in the tribe Opsiini, although only Lampridius has paired aedeagal shafts with separate gonopores. All six species are illustrated, and a key is provided for their identification. Problems with the current tribal classification are discussed in light of the present discovery of closely related species that show variation in characters previously assumed to be stable at the tribal level in the subfamily Deltocephalinae.
