查看更多>>摘要：Keys to the males of the Dolichoderinae ant genera known from the Southwest Indian Ocean islands (Comoros, Madagascar, Mauritius, Mayotte, Reunion, and Seychelles) are provided. Diagnoses, discussion, illustrations, and a character matrix are providedfor all five extant genera from the region: Aptinoma, Ochetellus, Ravavy, Tapinoma, and Technomyrmex. A male-based synopsis of the subfamily Dolichoderinae based on the five genera is also given. The previous diagnostic characters for the included genera are reconsidered. Terminologies for male genitalia and wing cells are reviewed.
查看更多>>摘要：A new endemic deltocephaline leafhopper, Tetramelasma gen.n. is described from the Grassland Biome of South Africa, comprising four new species: T. litopyx sp. n., T. nodosatha sp. n., T. scolosatha sp. n. and I! tanyphysis sp. n. Two paired dark markings on the vertex of the head are striking features of this genus and it is found in association with a number of grass species usually at high altitudes in the Grassland Biome. Species of this genus are characterized in the male by a short, truncated plate with a dorsal sclerotized process, the aedeagus with a long, slender shaft that is fused with the connective. Tribal placement in Deltocephalini is based on the fusion between the aedeagus and connective. The style has the posterior apophysis shortand hollow or elongate and somewhat serrated. Females are characterized by the sternite 7 that is deeply invaginated along the posterior margin or only with a shallow notch, semicircular and sclerotized laterally.

One new species from China, E. macrospinus sp. n. is described and a key to species is provided.While identifying leafhoppers of the grass feeding-tribe Macrostelini from China, the first author found a species which did not belong to any known Chinese genus of the tribe. Upon further investigation it was found to be a new species of Evinus Dlabola, previously known from Iran, Tajikistan and Kyrgyzstan. This genus was originally placed in Hecalini but recently Zahniser and Dietrich (2008) proposed that it might be more closely related to Macrostelini. More recently, an analysis of combined molecular and morphological data,(Zahniser and Dietrich 2010), did not find strong support for the placement of Evinus. Macrostelini was supported in the analyses (included taxa were Balclutha, Macrosteles and Dalbulus) but, depending on the kind of analysis,Evinus was placed either close to members of Chiasmini (a newly descrbed genus from Brazil) or to Stenometopiini, although support for any of these relationships was very low. In the present paper we formally place Evinus in Macrostelini based on morphology (see remarks below), describe the new species, and provide a checklist and key to species of Evinus.

The subgenus Drilothilmanus Pic, 1918 is synonymized with the nominotypical genus on the basis of low morphological divergence and redundancy in classification. Pseudothilmanus is newly classified in the family Rhagophthalmidae, in contrast to the original placement in Drilidae. Diagnostic characters for Pseudothilmanus and both species placed within the genus are illustrated.

查看更多>>摘要：Bemisia flocculosa sp. n. is described from Melicytus obovatus (Violaceae) trees in New Zealand. It is similar in structure to B. tabaci and also to B. capitata, differing from the former in its wax producing habit, the associated wax producing callosity areas, and lingula shape, and from the latter in the lingula shape and lack of capitate setae. In the production of white dorsal wax secretions it resembles species previously placed in Lipaleyrodes, but B. flocculosa produces waxes along the discal/submarginal arc and in the center of the disc, rather than on the submarginal areas.
