The morphological and molecular analyses presented in this study confirm the taxonomic validity of A. murcius and the absence of A. aestivalis in the Iberian Peninsula. The shape of the left paramere emerged as the only valid characteristic to differentiate both species. Specimens of Aphelocheirus from northern Spain, previously identified as A. murcius, formed an independent lineage genetically distinct to A. murcius and A. aestivalis, although morphologically indistinguishable from A. murcius.

查看更多>>摘要：Two new species, Parisotoma sexsetosa sp. nov. and P. obscurocellata sp. nov., are described from the Westem Cape Province in South Africa. The former is characterized with 2+2 ocelli and 4 sensilla in the p-row on each side of three first abdominal segments, the latter with 5+5 or more ocelli and 3+3 chaetae on the postlabial area. Both species have only 6 posterior chaetae on dens. A comparison of South African and Asiatic Parisotoma species is given. Sensillar chaetotaxy of the third and fourth abdominal segments is critical in the separation of these geographically distinct groups.

This work describes the new cicada Cicadetta anapaistica sp. n. which was detected in the Madonie and Nebrodi Mountains (Italy, Sicily). The characteristic and sophisticated song is composed of three phrases, modulated on four typical power levels and three frequency ranges. The song pattem is compared with those of the closely related Cicadetta cerdaniensis and Cicadetta cantilatrix. Quantitative and even qualitative intraspecific differences of the song stmcture among individuals exist which appear to allow individual-specific recognition in many cases. As in other species of the complex, reliable morphological differences between the new species and others in the complex have not been found. The species is currently only known to be endemic to forest and ecotone habitats in a small mountain range. Because of this limited distribution the species is likely to bevulnerable to habitat and climate changes.

查看更多>>摘要：Among the Anatolian Tettigoniinae (Orthoptera, Tettigoniidae) the genera Anterastes, Koroglus, Sureyaella and Rhaco-cleis are distinguishable from the others by presence of one pair of spurs on the apico-ventral end of hind tibiae. The last two can beeasily distinguished from the others by several distinct features, but the separation of the first two from each other is problematic. A new species described here provided opportunity of re-evaluating their taxonomy. The new species Anterastes antecessor sp. n. is described based on morphology, male calling song and genetic data. The taxonomy of Anterastes and Koroglus is rectified based on phylogentic hypotheses obtained from representative 16S rDNA haplotypes. Sureyaella bella, Parapholidoptera signata and Bolua turkiyae are used as out groups in different combinations to obtain a more stable phylogeny. Although analyses with different outgroups suggested the same topology, the phylogenetic tree with outgroups Parapholidoptera signata and Bolua turkiyae resulted with the highest bootstrap supports to the branches. Phylogenetic trees suggested the following relationships for the ingroup species; (A. antecessor sp. n. + ((Koroglus dis-paralatus + A. uludaghensis) + (A. turcicus + (A. niger + (A. ucari + A. babadaghi))) + ((A. tolunayi + (A. serbicus + A. antitauricus + A. burri)))). Considering the phylogenetic hypotheses and characters used in previous publications, Koroglus is put in synonymy with Anterastes, and a new combination is suggested for the only species of the former Anterastes disparalatus comb. n. A short remark is given about the characters used in the generic taxonomy of the group.

查看更多>>摘要：Five new species of Keilbachia Mohrig are described: Keilbachia adstricta, K. constricta, K. cracens, K. fratercula and K. truncata. The species are the first sciarids recognized from New Caledonia and are similar in stmcture to the New Guin-ean K. indigena Mohrig and the Indomalayan K. adunca Hippa & Vilkamaa. A key to the Australasian species of Keilbachia is provided. Various groups of the Diptera of New Caledonia have been studied rather intensively since the late 1980's, and the results have been published mainly in the seven volumes of Zoologia Neocaledonia (Tillier 1988, Chazeau & Till-ier 1991, Matile et al. 1993, Najt & Matile 1997, Najt & Grandcolas 2002, Grandcolas 2008, 2009). Of the Bibion-omorpha, the known New Caledonian fauna includeBibionidae (Fitzgerald 2004) and some groups of Sciaroidea (Matile 1986: Lygistorrhinidae, Matile 1988a: Ditomyiidae, Matile 1988b: Keroplatidae, Matile 1991, 1993: some mycetophilid tribes). These studies show a high degree of endemism of the New Caledonian fauna, at least at the species level. However, the level of endemism in New Caledonia varies widely among insect groups (Cranston 2010). This is the first part of an ongoing study of the New Caledonian sciarid fauna in preparation by the present authors.
