Four spider species were found in the artificial tropical ecosystem of the Biodôme de Montréal (Québec, Canada): Steatoda triangulosa (Theridiidae), previously reported from Québec and Ontario, Coleosoma floridanum (Theridiidae), Theridion melanostictum (Theridiidae), and Scytodes fusca (Scytodidae), which have never been recorded in Québec. These species were likely to have been imported from Florida along with plants used in the reconstruction of this tropical ecosystem. The occurrences of these species demonstrate an inefficiency in quarantine procedures. Each species is diagnosed and illustrated in order to facilitate their monitoring and possible invasion of natural habitats from this source of introduction.

A lectotype is designated for Cicada tibicen Linné, 1758. The Linnaean specimen located in the Zoological Museum of Uppsala University can be traced to Linné and the original species description. The species is determined to be the same as what is currently recognized as Tibicen chloromerus (Walker, 1850), making T. chloromerus and Cicada sayi Smith and Grossbeck, 1907, junior synonyms of Tibicen tibicen (L.).

The genus Mesotrichosiphum Calilung, an endemic southeastern Asian group, is reviewed to include Mesotrichosiphum pentaiarticulatum Zhang and Qiao, sp. nov. from China (Hainan). The generic diagnosis is supplemented in here, and a key is given to all species worldwide. Some hitherto unknown morphs of Mesotrichosiphum are described. New data on distributions and host plants are reported for the genus. The type specimens are deposited in Zoology Museum, Institute of Zoology, Chinese Academy of Sciences.

The effect of multiple immersions on Haemagogus janthinomys Dyar, 1921 eggs and the development of its immature forms were studied. Eggs of Hg. janthinomys from Linhares (state of Espírito Santo) were submitted to multiple immersions, counting the number of hatched eggs and observing the periods for development until adult. The egg-hatching proportion attained 42–88% (mean=68.2%), after 16 immersions, in three trials. After 8–9 immersions, the effect of additional immersions was negligible. The periods for development of immature forms were 3.67±0.89, 1.2±0.66, 1.12±0.63, 4.86±1.77, 2.25±0.67 and 12.40±0.82 days, respectively for 1st-4th instar larvae, pupae and the total. The postponement of the egg-hatching can be important for the production of mosquitoes, from one egg batch, during several months. The total period of larval development is very similar to previous indirect field calculations in the Brazilian state of Para and to mosquitoes from Panama studied in the laboratory.

We describe the mature larva of Sefrania bleusei Pic and establish the new genus Araphonotos Beal and Kadej for the reception of S. sabulorum (Beal). We argue the latter species is erroneously assigned to the genus Sefrania. Tables comparing S. bleusei and A. sabulorum indicate a generic distinction between the two. Also provided are important differences between Araphonotos and the type species of Novelsis (Attagenus horni Jayne), the genus to which S. sabulorum was initially assigned.

Ectolachesilla ariasi n.g., n. sp., is described from a single female collected in the state of Amazonas, Brazil. It belongs in subfamily Lachesillinae, and presents a combination of characters that makes it quite distinct from the other genera in the subfamily. Wing venation is caeciliusid, gonapophyses have a sclerotized band anteriorly, and the subgenital plate has two short, setose, postero-lateral lobes. A key to the genera of Lachesillinae is provided. The female holotype will be deposited in the INPA Collection, Manaus, Amazonas, Brazil.

A new species of Baleja Melichar, 1926, is described and illustrated based on specimens from Colombia (Nariño and Valle del Cauca departments). Baleja bella sp. nov. can be distinguished from other species of the genus mainly by the color pattern and male genital structures. The new species presents on the head a pair of peculiar lenticular sclerites, delimited by the loral sutures and adjacent to the frons, which are for the first time reported for Baleja. Taxonomic notes on the genus are included.

Two new species belonging to the genus Rhinoppia of the family Oppiidae were described and illustrated based on adult specimens collected from Artvin province, Turkey. One of these species, Rhinoppia artvinensis n. sp., was found in litter and soil under plum trees (Prunus domestica), and the second species, Rhinoppia tasdemiri n. sp., was found in moss pads on the ground in a mixed forest (mostly Pinus sylvestris) and in the same place as for the previous new species.

Three new species of the genus Orfelia Costa are described from China: O. baishanzuensis Cao et Xu, n. sp.; O. helvola Cao et Xu, n. sp.; O. maculata Cao et Xu, n. sp.. These new species belong to the O. nemoralis Meigen group. A key to Chinese species of Orfelia is given to aid in their identification.

The female of Ctenioschelus chalcodes Thiele is described from northwestern Costa Rica. Lacking the characteristic antennae of the male, the females are not easily distinguished from those of C. goryi (Romand). The lack of strongly violet iridescent scales on the head and mesosomal dorsum of C. chalcodes and the largely concave dorsum of the mesoscutellar tubercles distinguish females of this species from those of C. goryi. Most external characters of the additional male specimens of C. chalcodes agree with those mentioned in the original description. The geographic distribution of C. chalcodes in Costa Rica seems to be restricted to dry forest in the northwest, whereas C. goryi occurs in wet forests throughout the rest of the country, indicating a parapatric distribution pattern for the two species. Nectar host plants and associated species are provided, but no bee hosts for these cleptoparasitic species could be determined so far. A key to the species is provided.

Xysticus anatolicus n.sp. (Araneae: Thomisidae) is described in the male sex from Kayseri Province, Turkey.

A new species of the genus Cymodusa (Cymodusa) Holmgren, [1859] from Turkey is described and figured. It is distinguished from the similar C. (Cymodusa) oculator Dbar, 1985 by elongated basal area and area superomedia of propodeum, moderately narrowed behind head, developed clypeal fovea, no intercepted nervellus and coloration of the body.

The present study is based upon the material collected from Kars provinces in recent years. Two species, Therion brevicorne Gravenhorst and Syzeuctus irrisorius Rossi have been recorded in the subfamilies Anomaloninae and Banchinae respectively as new for the Turkish fauna. Short descriptions of the species are given with drawing.

Two junior homonyms were detected amongst the genera of Melolonthinae and the following replacement names are proposed: Brittonius nom. nov. for Bryantella Britton, 1957 and Bezdekia nom. nov. for Metagonia Kolbe, 1899. Accordingly, new combinations are herein proposed for the species currently included in these genera.

The parasitoids of Nothris verbascella larvae (Lepidoptera: Gelechiidae) found on Verbascum densiflorum and V. sinuatum (Scrophulariaceae) in Edirne, Turkey were studied between May 2005 and May 2007. Three species of Ichneumonidae (Hymenoptera) were recorded as parasitoids of N. verbascella (Temelucha interruptor, T. decorata, and Tricholabus femoralis). Parasitoidism by T. decorata on N. verbascella larvae is a new record for Turkey. In addition, we first report new host-parasitoid relationships: N. verbascella with T. interruptor and Tricholabus femoralis. Tricholabus femoralis is also a new record for the Turkish fauna. The presence of N. verbascella on V. densiflorum and V. sinuatum is a new record. This study also reports the first host record of Tricholabus femoralis.

Two junior homonyms were detected among leafhopper genera and the following replacement names are proposed: Nallia nom. nov. for Nollia Hamilton, 1983, and Neosuarezia nom. nov. for Suarezia Linnavuori and DeLong, 1978. Accordingly, new combinations are herein proposed for the species currently included in these genera: Nallia pallida (Linnavuori and DeLong, 1977) comb. nov.; Nallia rustica (Hamilton, 1983) comb. nov.; Neosuarezia reflexus (Osborn, 1923) comb. nov.
