Using pitfall traps, we studied the taxonomic diversity of epigean tenebrionids in the Chores Archipelago, formed by the Choros, Damas and Gaviota Islands, which are part of the Pingüino de Humboldt National Reserve. We identified fourteen species arranged in eight genera and six tribes, of which seven species were common to the archipelago. Five genera are reported for the first time as occurring in insular habitat islands: Psectrascelis Solier, Entomochilus Solier, Diastoleus Solier, Scotobius Germar, and Thinobatis Eschscholtz, Gyriosomus granulipennis Pizarro-Araya and Flores is recorded as endemic to the Choros Island.

Telenomus thaumetopoeae Buhl sp. n. is described from northeastern València (Peninsular Spain) taking as starting point females parasitizing the egg-batches of the Pine Processionary Moth, Thaumetopoea pityocampa (Dennis et Schiffermüller, 1775). Its morphological affinities with the most closely related species and parasitism data are offered.

We investigated the antennal morphology, sensillar types, and sensillar distribution in the dark (“melanic”) and the light (“succinea”) forms of Asian multicolored ladybirds, H. axyridis, using scanning electron microscopy (SEM). Antennae of both sexes of H. axyridis consist of the scape, pedicel, and nine flagellomeres. Seven sensillar types are distinguished: four types of sensilla trichodeae (s.tr), four types of sensilla basiconicae (s.ba), four types of sensilla chaetica, and one type each of sensilla coeloconica (s.co), sensilla sporangium (s.sp), sensilla placoidea (s.pl), and Böhm bristle (s.bm). Sensilla trichodea are the most numerous; sensilla chaetica are the next most abundant. The number of other sensillar types is greatly reduced. On the tip of the 9th flagellomere, various types of sensilla are densely packed, except for s.bm and s.pl. No remarkable differences are found in the antennal size, shape, and sensillar types between the melanic and succinea forms of H. axyridis, but there is a difference in the total number of s.tr.2 between the two forms. No differences are found in the antennal size and the total number of sensillae between males and females of each form. According to the distribution of sensillae and sensillar functions reported in the past, s.tr are presumed to be pheromone receptors in H. axyridis, s.ch may function as mechanoreceptors and chemoreceptors, s.ba and s.co are postulated as plant volatiles receptors and chemo-, thermo-, or hygroreceptions, respectively, and s.bm may be related to perceiving the antennal position and movement.

The genus Megissus and type species Megissus acutus, described by Linnavuori in 1965 from one locality in Turkey, are redescribed based on the examination of material from a new locality in Turkey.

Eleven stonefly species representing seven genera and five families were collected during a two-year period of Malaise trapping and sweep netting at Mount Misery Brook, a small acidic, blackwater stream in the New Jersey Pinelands. The most common species, Allocapnia pygmaea, was collected from January through April. Leuctra ferruginea, the second most common species, was collected mainly in April and September through December. Nine new stonefly records are added for the state of New Jersey: Allocapnia pygmaea, Leuctra carolinensis, Leuctra ferruginea, Leuctra variabilis, Acroneuria lycorias, and Isoperla burksi from Mount Misery Brook (Burlington Co.); Paracapnia angulata from Babcock Creek (Atlantic County), Leuctra duplicata from a bog in Franklin Parker Preserve (Burlington Co.); and Pteronarcys dorsata from the Delaware River (Hunterdon County).

Two new fossil species of the family Limoniidae, Architipula abnormis sp. nov. and Architipula conformis sp. nov., are described and illustrated. These two new species are established based on fossil specimens with complete wings and bodies. Both of them were collected from the Middle Jurassic Jiulongshan Formation of Daohugou in Eastern Inner Mongolia, China.

A new species of the genus Ichilocoris assigned to the coreid tribe Acanthocephalini is described from Argentina and Brazil as the second member of the genus. Illustration and a key to the known species are provided.

Oedophrys hilleri (Faust), native to East Asia, has become established in the north-eastern United States. This study examined the feeding preferences of adults, larval food and phenology of adults in an unsprayed peach orchard. Adults fed on the foliage of plants in the Rosaceae family preferring peach (Prunus persicae) and pear (Pyrus communis). There was one generation per year, adults were most abundant in late June to early July but were present whenever trees were actively growing. Eggs were laid on the soil surface. Larvae fed on the fine roots and the cambium and xylem tissues of small woody roots of peach trees; roots of other species were not tested. In field observations, adult feeding removed up to 15% of the foliage on individual branches. An estimated high of 337 adults/m² emerged from the soil under peach trees based on enclosed emergence traps. Although heavily infested trees showed no apparent loss of vigor compared with trees in the same orchard with low levels of defoliation, this exotic insect could be of concern to growers when combined with other orchard stresses.

A new species of the genus Hessebius Verhoeff, 1941 (Lithobiomorpha: Lithobiidae) is described, discovered in China. Hessebius longispinipes n. sp. was found in Xinjiang Uygur Autonomous Region. The new species can be distinguished from all other Hessebius by its distinctive backwards, long terminal thorn of the second section of the female gonopods.

Mesoleptogaster cappadocia n. sp. from Central Anatolia, Turkey, is described. Drawings of the male genitalia, the female spermathecae, wing, leg and antenna are provided. A key to the Palaearctic species of Mesoleptogaster is included.

Caterpillars of the genus Hylesia (Lepidoptera: Saturniidae: Hemileucinae) can cause agricultural damages and dermatological lesions by direct contact to its urticating bristles. The biological control can regulate populations of these insects, but their natural enemies are poorly known. The occurrence of Harpactor angulosus (Lepeletier and Serville, 1825) (Reduviidae: Harpactorinae) predating caterpillars of Hylesia spp. is described. Adults of this predator were captured in an area of secondary forest in Viçosa, Minas Gerais State, Brazil and their pairs individualized in the field to obtain eggs. Adults of this predator presented sex dimorphism, with smaller males than females. They were found predating caterpillars of Hylesia spp., isolated from others to avoid the aposematic defense of this prey, when grouped. The presence of this predator, in the field, demonstrates its potential for the biological control of defoliating caterpillars. Studies on biological aspects and alimentary habits are important to understand the importance of H. angulosus in the biological control of defoliating caterpillars.

A new species of Pseudosinella, P. mallorquinensis sp. nov., is described from Balear Islands, Spain.

Se describe e ilustra una nueva especie de Pseudosinella, P. mallorquinensis sp. nov. de las Islas Baleares, España.

A study of scale insects (Coccoidea) on oak trees (Quercus sp., Fagaceae) was undertaken between April and October in 2005 and 2006 in Bulgaria (B) and Greece (G), mainly in regions of beekeeping interest, to determine the sources of honeydew utilized by the bees. A total of 12 species of scale insects were collected: Coccidae: Eulecanium tiliae Linnaeus (B and G), Eulecanium ciliatum Douglas (B) and Parthenolecanium rufulum Cockerell: (B and G); Diaspididae: Targionia vitis Signoret (B and G), Lepidosaphes ulmi Linnaeus (B), Diaspidiotus wuenni Lindinger (G), Diaspidiotus zonatus Frauenfeld (G) and Diaspidiotus lenticularis Lindinger (G); Kermesidae: Kermes roboris Fourcroy (B) and Kermes gibbosus Signoret (B); Eriococcidae: Eriococcus sp. (B and G), and Asterolecaniidae: Asterodiaspis repugnans Russell (B and G). Only 6 of these species are honeydew-producing insects, and only 3 of them (Eulecanium tilliae, Parthenolecanium rufulum and Eriococcus sp.) were found in both Bulgaria and Greece. As Parthenolecanium rufulum is the most widespread species, it is most likely to be the main source of honeydew from Coccoidea. Among the species collected, the asterolecaniid Asterodiaspis repugnans (Russel) is a new record for Bulgaria, and the diaspidid Diaspidiotus wuenni (Lindinger) is a new record for Greece. Biological information, such as, host plant, developmental stage, distribution and some phenological data are given.

A junior homonym was detected amongst the beetles genus group names, and the following replacement name is proposed: Miksicus nom. nov. for Urbania Miksic, 1963. Accordingly, new combinations are herein proposed for the species group names currently included in this genus.
