Two new species of the Delia interflua group are described, Delia absidata Xue and Du, sp. nov., and Delia subinterflua Xue and Du, sp. nov. The group is briefly discussed and a key to all the known species is presented

Behavior patterns associated with spermatophore transfer have been studied in several species of insects, but in stoneflies, even the existence of a spermatophore has been uncertain. This study aimed to confirm the existence of spermatophores in Stavsolus japonicus (Plecoptera: Perlodidae) and to determine the manner of spermatophore transfer. The male bent its body into an S-shape and inserted its abdominal caudal tip between the sternites and the subgenital plate of the female to open the female's subgenital plate. After approximately one hour, the male started to stroke the female's eighth and ninth genital segments with its epiproct. Next, the aedeagus was extruded between the male's eighth and ninth sternites and a spermatophore-like mass was extruded from the aedeagus. The mass contained sperm and was thus considered to be a spermatophore. The spermatophore was placed directly under the female's subgenital plate by the aedeagus and the male then patted the spermatophore with his cerci.

The genus Osbornellus is reviewed for Hispaniola. Seventeen species are now known from this island, two described species, bimarginatus (DeLong) and fasciatus Metcalf, and fifteen new species from the Dominican Republic. The new species are: dipilus, bellus, coloritubus, brevitubus, tubus, eccritus, dicellus, proximus, arcus, venustus, hispanus, sagarus, parvus, eratus, and tetrus. A key to all species is included.

Fourteen species and subspecies of Turkish Carabinae belonging in the family Carabidae were examined in detail. This represents about 15% of the Carabinae fauna of Turkey. This study is based on material collected from different altitudes and climatic conditions and from localities of different vegetation, between 2004 and 2005 from Kahramanmaraş and the surrounding towns located in south central Turkey. Adult length/width body ratios, photographs of the adults, detailed descriptions of the male genital organs and photographs, collecting localities, distribution in Turkey and in the world, as well as chorotypes are given for each species.

The present paper describes a new species of the genus Australobius Chamberlin, 1920 (Lithobiomorpha: Lithobiidae) recently discovered in Tibet, China. Australobius anamagnus from Lhünze County, Shannan City. The cephalic shield, tergites, coxosternum and certain other diagnostic characters of the new species are illustrated.

Eight new species are added to the genus Chiasmodolon, C. infraspina, C. lozadai, and C. guttatus from Peru; C. guianae from French Guiana; and C. anchylus, C. nodus, C. eluphus and C. circulus from Colombia.

Culicoides paraensis (Goeldi), a vector of the human viral disease Oropouche, is reported as a pest from five cities in the Itapocú River Valley, southern Brazil. Adults likely emerge from rotting banana plants and are common enough to cause skin problems and allergies.

Four new species are described from Colombia. All belong in the Cicadellini in three different genera. They are: Hadria colombiana, Coronigonalia litterata, Coronigonalia gorgonensis, and Stephanolla spina.

Oxycera guizhouensis sp. nov. from Guizhou Province and the male of O. lii Yang and Nagatomi from Sichuan and Yunnan Provinces are described. All essential diagnostic characters are figured and possible relationships of both taxa are briefly discussed.

The genus Matratinea Sziráki, 1990 is recorded for the first time from China. Two new species are described based on the specimens collected from Hubei, Fujian and Gansu provinces of China. The photographs of the adults and the male genitalia as well as the drawings of the venations are provided. A key to the species of the genus is given.
