Hoplopleura paranaensis sp. nov. is described from specimens collected from Deltamys kempi Thomas, 1917, on the Delta del Paraná, Buenos Aires Province, Argentina. Detailed descriptions of sexes, the three nymphal instars, external architecture of eggs (by scanning electron microscopy), and sites of oviposition are provided. Differences from Hoplopleura aitkeni Johnson, 1972 are included. A key and discussion of the distribution of the ten species of the aitkeni-group on their hosts, and their respective geographical ranges in Argentina is also given.

This study was carried out in various localities in five provinces of the Turkish Thrace, between the years 1992 and 2003. A total of 101 species from six heteropteran families (Pentatomidae, Scutelleridae, Thyreocoridae, Cydnidae, Acanthosomatidae and Plataspidae) were determined, 22 of the species are new records of the Pentatomoidea for the Turkish Thrace. Of these, three species (Thyreocoris fulvipennis, Neottiglossa lineolata, Podops inuncta) are first records for Turkey. It seems that Podops is a new genus record for Turkey. Picromerus brachypterus, which has previously been recorded from Anatolia (Turkey), is considered a new record for Europe.

The systematics of Phlebotomine sandflies has been studied and discussed since the beginning of the 20th century, and many systems have been proposed. Complex and well-based systems, dividing Phlebotominae in many genera and subgenera, proposed for Old and New World species, have been progressively understood and accepted by the workers in the subfamily. Due to its complex nature, a system of abbreviations, similar to that utilized for Culicidae, is proposed here for these groups of Phlebotominae. It uses two letters for genera and three for subgenera.

Neotournieria ambigener n. sp. from Turkey is described and compared with the three known species of the genus. The new species is the only amphigonic known member of Neotournieria.

The pupa of Paryphoconus oliveirai Lane is described from a specimen collected from a sandy bottom of a shallow human disturbed stream near Manaus, Brazil. The pupa of P. oliveirai is compared with previous descriptions of the pupa of this species and with the pupae of its congeners, P. flavidus (Johannsen), and P. mayeri Wirth.

A new genus Sinocaryanda gen. nov. is proposed for Sinocaryanda macrocercusa sp. nov. from Yunnan, China. The new genus is an aberrant member of the Oxyinae and resembles Caryanda Stål, 1878, and Nepalocaryanda Ingrisch, 1990. It differs from the latter two by the following features in male: terminalia dorsally broad; 10th tergite broadly interrupted in midline with widened, rounded, medial margins; cerci reaching to or beyond apex of subgenital plate; epiphallus not divided in middle, and aberrant connecting mode of anchorae with bridge.

A new species of Psylliodes (Coleoptera: Chrysomelidae: Alticinae), P. kasnakensis, is described and illustrated from Isparta, southwest Turkey. The new species, a member of the P. picina Marsham species group, is compared with its congeners. The distinguishing features of the species are specified; habitat and host plant notes are presented.

The species Phtheiropoios susquensis sp. nov. is described and illustrated from specimens of Ctenomys sp. collected from Laguna Múcar, Susques District, Jujuy Province, Argentina. Diagnostic features for the new species include a proportion of male forficula, male external genitalia, and counts of setae, body measurements in both sexes and external architecture of the egg. Its morphological affinities with allied species are briefly commented. A key to males of all species of the genus Phtheiropoios known to parasitize rodents of the genus Ctenomys, is included.

Two new genera and six new species related to the genus Hadria are described from Hispaniola. Parahadria new genus, includes but the type species P. octolineata n. sp. Neohadria new genus, includes five new species, N. maculata, type species, N. amaurota, N. delecta, N. diversa, and N. grisea. Parahadria octolineata is found commonly throughout the island, while all Neohadria species are found only in the higher elevations of the central and western part of the island.

The genus Lambertiodes Diakonoff is reviewed, with Lambertiodes multipunctata sp. nov. described as new to science. The adult and genital structures of the new species are illustrated, and keys to distinguish the two known species of Lambertiodes are provided.

Hyperaspis brunnescens Dobzhansky is newly recorded in Canada and eastern North America from a stormpetrel burrow on Scatarie Island, Nova Scotia. This record extends the range of the species 2,100 km to the east. Hypotheses with respect to the ecology of the species are discussed, as are possible zoogeographic scenarios that might account for its presence in Nova Scotia.

Baetisca laurentina McDunnough is reported for the first time from West Virginia. One male imago was collected near Twelvepole Creek, Wayne County, West Virginia. This record extends the range of this species eastward to the Mid-Atlantic coastal region. New distributional records (57) of Baetisca spp. are reported for Kentucky (15) and West Virginia (42). The following county records have been added to the list of Baetisca spp. from the two states: Baetisca berneri Tarter and Kirchner (KY/1 and WV/13), B. carolina Traver (WV/3), B. gibbera (WV/1), B. lacustris McDunnough KY/14 and WV/22), B. laurentina McDunnough (WV/1), and B. rubescens Provancher (WV/2). Baetisca lacustris is the most widespread baetiscid in West Virginia (26 counties) and Kentucky (25 counties). This species was found in six drainage basins (I, II, IV, V, VI, VII) in West Virginia. Only one baetiscid mayfly, B. rubescens, was recorded for drainage basin III.

Liris ferrugineimarginalis new species from Guangdong and Fujian, China, is described and illustrated. A key to the Chinese species of the genus is provided.
