Description of a second species of Nannogonalia Young, 1977 (Insecta: Hemiptera: Cicadellidae: Cicadellini) from the Atlantic Forest of south Brazil

A second species of the poorly known sharpshooter genus Nannogonalia Young, 1977 is described and illustrated from the Atlantic Forest of south Brazil (state of Paraná). Types are deposited in DZUP. Nannogonalia inusitata n. sp. can be distinguished from the type-species (Tettigonia circumcincta Signoret, 1855) mainly by the color pattern and form of the male subgenital plates and female sternite VII. Nannogonalia circumcincta is newly recorded from the state of Paraná. The female genitalia of Nannogonalia are described in detail for the first time, based on the type-species and the new species. We discuss some peculiar features of the first and second ovipositor valvulae of this genus that were previously observed in Versigonalia Young, 1977.

Interesting findings of spiders of the families Gnaphosidae and Liocranidae (Aranei) from the semidesert of the northern Caspian Lowland

D. rostratus is shown to be a valid species but not a junior synonym of Drassodes auritus Schenkel, 1963. The genitalia of Haplodrassus isaevi Ponomarev et Tsvetkov, 2006, a new species for Western Kazakhstan, are described and illustrated. The family Liocranidae is represented by three species. Agraecina lineata (Simon, 1878) is described as a new genus and a species of liocranids for the Republic of Kazakhstan.     

Systematic and morphological studies of the genus Chaetopleurophora Schmitz (Diptera: Phoridae) occurring in Japan

Japanese species of the genus Chaetopleurophora are reviewed. All belong to the C. erythronota group. The following three species from Japan are described: C. rhomboidea sp. nov., C. pygidialis Schmitz and C. dividua sp. nov. The male and female genitalia are studied and further examples of unique characters of the genus including asymmetric features are added. The male aedeagus of the genus is illustrated for the first time. The aedeagus of the species treated in this study consists of only two components, the inner core plate and the outer jacket plate. The jacket plate wraps sinistrally around the core plate. The combination of the core plate and the jacket plate forms complex, asymmetric features of the aedeagus in the Phoridae. The structure around the genital opening in the female genitalia protrudes posteriorly under the segment IX + X, and shows asymmetric features in C. rhomboidea sp. nov. with a bilaterally different degree of sclerotization, shifted genital opening to the right side and a membranous ribbon just on the left side. In addition, C. dividua sp. nov. is different from most of the species in the C. erythronota group, and very closely related to C. multiseriata (known in North America) in the male and female genitalia, wing venation and bristle formation on the scutellum. It is suggested that C. dividua sp. nov. forms a monophyletic group with C. multiseriata and the related species.     

Anagnorisma chamrani sp. n. (Lepidoptera,Noctuidae) from Iran

Tacora johanni, a new species from Rondônia State, North Brazil, is described and illustrated. The new species can be recognized by the male genital features, especially the subgenital plates with the basal half distinctly expanded and with outer lateral margin round, the long and slender preapical pygofer process, and the styles with apical half strongly curved. Also, the genus is recorded for the first time from Venezuela, based on specimens of Tacora saturata Young, 1977, while the female of this species (here described in detail for the first time) shows two unusual features of the genitalia. A key to males of all known Tacora species and a map showing the known distribution of the genus are provided.

The new species is associated with Diospyros maritima Blume and is very similar to S. masinissa Meyrick, which is a notorious pest of persimmon, D. kaki L., in Japan and Korea. The adult external features, wing venation, and male and female genitalia of both species are illustrated and compared in detail.
