In this study, we surveyed aphids and associated parasitoid wasps from six important crop species (wheat, sweet pepper, eggplant, broad bean, watermelon and sorghum), collected at 12 locations in the Kurdistan region of Iraq. A total of eight species of aphids were recorded which were parasitised by eleven species of primary parasitoids belonging to the families Braconidae and Aphelinidae. In addition, four species of hyperparasitoids (in families Encyrtidae, Figitidae, Pteromalidae and Signiphoridae) were recorded. Aphelinus albipodus (Hayat & Fatima, 1992), A. flaviventris (Kurdjumov, 1913), A. varipes (Förster, 1841) (Aphelinidae), Aphidius rhopalosiphi (De Stefani, 1902), A. uzbekistanicus (Luzhetzki, 1960), (Braconidae) and Alloxysta arcuata (Kieffer, 1902) (Figitidae) were recorded in Iraq for the first time. The results represent the first survey of these interactions in this region and form the basis for understanding crop-aphid-parasitoid-hyperparasitoid networks and for future biological control actions.

The collections of fungus gnats by Johan Wilhelm Zetterstedt (1785–1874), lodged in the Museum of Zoology in Lund, Sweden, are examined for all species belonging in the tribe Exechiini Edwards. The majority of the material was collected in Fennoscandia, mainly in Sweden, in the first half of the 19 th century. Altogether 37 species of the tribe Exechiini could be safely identified. Three additional species are strongly indicated to be present in the collections, but could not be identified with certainty, viz. Allodia (Brachycampta) alternans (Zetterstedt, 1838), Cordyla murina Winnertz, 1863 and Stigmatomeria crassicornis (Stannius, 1831). Some of Zetterstedt's types have been erroneously synonymized and misinterpreted in modern literature. Hence, illustrations of terminalia are presented for all recognizable Exechiini types described by Zetterstedt. In order to preserve nomenclatural stability a lectotype is selected for Brevicornu griseolum (Zetterstedt, 1852) sensu auctore nec Edwards, and a neotype is selected for Allodia (Brachycampta) alternans (Zetterstedt, 1838). Two species names are reinstated, viz. Brevicornu canescens (Zetterstedt, 1852) sp. restit. stat. n. and Notolopha brachycera (Zetterstedt, 1838) sp. restit. stat. n. Two new synonyms are established, viz. Notolopha brachycera (Zetterstedt, 1838) = Allodiopsis (Notol- opha) tuomikoskii Zaitzev & Maximova, 2000 syn. n., and Brevicornu griseolum (Zetterstedt,1852) = Brevicornu boreale (Lundström, 1914) syn. n. All type specimens of Brevicornu fusculum (Zetterstedt, 1838) have lost their abdomens. No material of Exechia parvula (Zetterstedt, 1852) or Cordyla canescens Zetterstedt, 1852 could be located in the collections. Although the type material of Exechia parvula probably is lost, the name is still valid as a junior synonym for Mycetophila nana Staeger, 1840 since Mycetophila nana Staeger, 1840 is a junior primary homonym of Mycetophila nana Macquart, 1826. Cordyla canescens has been made a junior synonym for Stigmatomeria crassicornis (Stannius, 1831). The identity of Brevicornu fusculum is highly uncertain and the name must remain as a nomen dubium. Eleven species are reinstated or correctly reported from Sweden for the first time: Allodia (Allodia) tuomikoskii Hackman, 1971, Allodia (Allodia) zaitzevi Kurina, 1998, Allodiopsis rustica (Edwards, 1941), Brevicornu canescens (Zetterstedt, 1852), Brevicornu nigrofuscum (Lundström, 1909), Exechiopsis (Xenexechia) crucigera (Lundström, 1909), Pseudexechia aurivernica Chandler, 1978, Notolopha brachycera (Zetterstedt, 1852) Synplasta gracilis (Winnertz, 1863), Tarnania dziedzickii (Edwards, 1941), and Tarnania nemoralis (Edwards, 1941).

Located in southwestern Maranhão, the Parque Nacional da Chapada das Mesas (PNCM), with an extent of about 160,046 ha, is completely inserted in the Cerrado phytogeographic domain. The topography is characterized by a plateau formation consisting of steep hills and medium-altitude mountains with flat tops, which give the PNCM its name. We present an annotated checklist of the mosses that occur in the PNCM. Our checklist includes 26 species of pleurocarpous mosses distributed in 10 families and 22 genera and two species of cladocarpous mosses of the family Orthotrichaceae. The most species-rich families of pleurocarpous mosses were Sematophyllaceae (7 spp.), Pylaisiadelphaceae (6 spp.), and Stereophyllaceae (4 spp.). Eleven species are recorded for the first time from Maranhão and three species are recorded for the first time in the northeast region of Brazil. Taxithelium pluripunctatum (Renauld & Cardot) W.R. Buck and Trichosteleum glaziovii (Hampe) W.R. Buck, are recorded for the first time from Maranhão and the Cerrado phytogeographic domain. Our results expand the knowledge of the Brazilian bryoflora and add distribution data for a number of species in Maranhão and the northeast region.

The organisation of the Sinapis alba genome, comprising 12 linkage groups (n = 12), was compared with the Brassicaceae ancestral karyotype (AK) genomic blocks previously described in other crucifer species. Most of the S. alba genome falls into conserved triplicated genomic blocks that closely match the AK-defined genomic blocks found in other crucifer species including the A, B, and C genomes of closely related Brassica species. In one instance, an S. alba linkage group (S05) was completely collinear with one AK chromosome (AK1), the first time this has been observed in a member of the Brassiceae tribe. However, as observed for other members of the Brassiceae tribe, ancestral genomic blocks were fragmented in the S. alba genome, supporting previously reported comparative chromosome painting describing rearrangements of the AK karyotype prior to the divergence of the Brassiceae from other crucifers. The presented data also refute previous phylogenetic reports that suggest S. alba was more closely related to Brassica nigra (B genome) than to B. rapa (A genome) and B. oleracea (C genome). A comparison of the S. alba and Arabidopsis thaliana genomes revealed many regions of conserved gene order, which will facilitate access to the rich genomic resources available in the model species A. thaliana for genetic research in the less well-resourced crop species S. alba.

AbstractConspecific host discrimination and larval competition in two aphid parasitoid species were studied in the laboratory using the pea aphid, Acyrthosiphon pisum (Harris) (Homoptera: Aphididae), as a host. Aphidius ervi Haliday (Hymenoptera: Aphidiidae) used internal host cues to discriminate between unparasitized and conspecific parasitized hosts. When only parasitized hosts were available, females oviposited into recently parasitized ones where their progeny had a good chance to survive, but rejected those parasitized ≥24 h earlier where their offspring normally died. Competitions occurred only after both eggs had hatched. Larvae eliminated supernumeraries by means of physical combat and physiological suppression. In Aphelinus asychis Walker (Hymenoptera: Aphelinidae), factors, or changes in host internal condition, associated with hatching of the first egg resulted in suppression of conspecific competitors which could be in either larval or egg stage. The older larvae always won competitions through physiological means. A wasp’s oviposition decision is shown to be influenced by the probability of its progeny’s survival. Species that have different reproductive strategies may respond differently to identical host conditions.

Stingless bees (Apidae: Meliponini) are culturally and economically important bees and they represent a major component of the Colombian melittofauna. However, the bee fauna of Colombia is still in early stages of exploration and species identification is often difficult or impossible. We revised the species of the cleptobiotic stingless bee genus Lestrimelitta in Colombia and recognized the following eleven species: L. glabrata, L. guyanensis, L. rufa, L. rufipes, and L. spinosa, which are recorded for the first time for the country; L. huilensis, L. opita, L. piedemontana, and two new species, L. diminuta, sp. n. and L. galvisi sp. n. We also confirmed the presence of L. limao in the Colombian Amazon and provide new geographical records with an updated key to species from Central America and northern South America

Fourteen species of Ichneumonidae are here recorded from the Maltese Islands. Of these, all were reared from Lepidoptera hosts with the exception of Netelia (Paropheltes) inedita (Kokujev) which was collected from a malaise trap. Of these, the following species (or genera) are here reported for the first time from the Maltese Islands: Chirotica meridionalis Horstmann, Gelis carbonarius (de Stefani), G. exareolatus (Fӧrster), G. seyrigi Ceballos, Glypta sp., Meloboris sp., Netelia (Paropheltes) inedita (Kokujev), Ophion obscuratus Fabricius and Orthizema sp. Twenty-five species of Braconidae are also here reported from Lepidoptera hosts with the exception of Homolobus (Phylacter) meridionalis van Achterberg which was collected from a malaise trap. Of these, the following species (or genera) represent new records for the Maltese Islands: Apanteles metacarpalis (Thomson), Ascogaster sp., Clinocentrus excubitor (Haliday) [previously misidentified as C. exsertor (Nees) by Papp (2015)], Cotesia vestalis (Haliday) [previously misidentified as C. ruficrus (Haliday) by Papp (2015)], Dolichogenidea britannica (Wilkinson), Homolobus (Phylacter) meridionalis van Achterberg, Iconella ? meruloides (Nixon), Lysitermus tritoma (Bouček), Lysitermus suecius (Hedqvist), Microgaster messoria Haliday, Meteorus pulchricornis (Wesmael), Pholetesor circumscriptus (Nees) [previously misidentified as P. bicolor (Nees) by Papp (2015)] and Spathius pedestris Wesmael. Thus previous records of Clinocentrus exsertor and Pholetesor bicolor from Malta were found to be based on misidentifications and are here excluded from the braconid fauna of Malta. Maltese records of Cotesia abjecta (Marshall) and Cotesia jucunda (Marshall) by Papp (2015) were found to be misidentifications and should both refer to C. glomerata (Linnaeus). Thus, both Cotesia abjecta and Cotesia jucunda are also here removed from the braconid fauna of Malta. The record of Cotesia tibialis (Curtis) by Papp (2015) was also based on a misidentification and should be attributed to C. ruficrus (Haliday). Thus, C. tibialis is also removed from the braconid fauna of Malta.

We report upon eleven species of thecate hydroids collected during a recent scientific expedition to the North Patagonian Zone between southern Chiloé and Puyuguapi fjord/ Magdalena Island. One species belongs to the family Haleciidae Hincks, 1868, four to the family Sertulariidae Lamouroux, 1812, and six to the family Campanulariidae Hincks, 1868. Of them, Halecium cymiforme Allman, 1888 and Symplectoscyphus leloupi El Beshbeeshy, 1991 are redescribed based on new, fertile material. Sertularella allmani Hartlaub, 1901 is assigned to the synonymy of S. antarctica Hartlaub, 1901. Campanularia subantarctica Millard, 1971 is considered as a junior synonym of C. lennoxensis Jäderholm, 1903, and data on both the male and female gonothecae are provided. A variant of Clytia gigantea (Hincks, 1866) with smaller hydrothecae than usual is described. Sertularella sanmatiasensis El Beshbeeshy, 1991 is recorded from Chile for the first time. Although not belonging to the present collection, several notes on Kirchenpaueria curvata (Jäderholm, 1904) are provided.
