Hoverflies are relevant to pollination, predation, phytophagy and decomposition processes and they are also used as bioindicators. The numerous recent advances in the study of Spanish hoverflies and the absence of species lists for the Spanish provinces prompted us to update the national catalogue and fill in the gap at the provincial level. Andorra and Gibraltar are also included in this review. A total of 421 species of 72 genera are included in the present catalogue (417 species in Spain; 86 in Andorra; 43 in Gibraltar). León (182 spp), Salamanca (143 spp), Madrid (134 spp), Ciudad Real (124 spp) and Huesca (121 spp) are the Spanish provinces with the highest numbers of species recorded. The Balearic Islands have 81 species and the Canary Islands 41, with one and 11 endemic species respectively. The richest hoverfly genera in Spain are Cheilosia (56 spp), Merodon (40 spp plus 1 sp from Gibraltar) and Eumerus (38 spp plus 1 sp from Gibraltar), all of them being Eristalinae; within the Syrphinae, Paragus is the richest genus (18 spp). The possibility of elaborating regional (provincial) species lists from the information provided in the present study also contributes to ‘Syrph the Net, the database of European Syrphidae’ as a tool for assessment of habitat conservation in Spain.

The West-Palaearctic cerioidines (Syrphidae: Cerioidini) are revised, including species of the genera Ceriana Rafinesque, Primocerioides Shannon, and Sphiximorpha Rondani. Three new species are described, Ceriana glaebosa van Steenis & Ricarte sp. n. (Cyprus), Ceriana media van Steenis & Ricarte sp. n. (Afghanistan and Iran) and Ceriana skevingtoni van Steenis & Ricarte sp. n. (Armenia, Azerbaijan and Iran). The following names are proposed as junior synonyms: Cerioides caucasicus Paramonov, 1927 [= Ceriana conopsoides (Linnaeus, 1758)], Ceria binominata Verrall, 1901 [= Sphiximorpha garibaldii (Rondani, 1860)], Ceriana worelli, Brădescu, 1972b [= Sphiximorpha garibaldii (Rondani, 1860)] and Sphiximorpha hiemalis Ricarte, Nedeljković & Hancock, 2012 [= Primocerioides regale Violovitsh, 1985]. Identification keys, biological data and distribution maps for the studied taxa are provided. Conops vaginicornis Schrank, 1803 is discarded as a synonym of Ceriana conopsoides and should be considered as nomen dubium.

The diversity of bee (Hymenoptera: Apoidea) and hoverfly (Diptera: Syrphidae) pollinators from ten localities in Vojvodina, Serbia was surveyed. Among different types of Pannonian habitat (grasslands, heathland and scrub, woodland and forest habitats) all localities were categorised as forest and steppe. They were in protected areas, mostly undisturbed by human activity. Censuses of pollinators took place from 30 March to 10 October, 2014. We recorded 218 pollinator species; 135 bee species (42 Halictidae; 32 Apidae; 29 Andrenidae; 24 Megachilidae; 7 Colletidae; 1 Melittidae) and 83 species of hoverflies. We describe a new species of hoverfly, Eumerus pannonicus sp. nov., and compare it to other similar species. Based on our study, the Special Nature Reserve of Pasnjaci Velike Droplje is critical for the conservation of this new Eumerus-being only found at this locality-and other species such as Chrysotoxum lineare (Zetterstedt), which is rare in Europe and protected under Serbian legislation. The highest numbers of bee species were recorded in the Deliblato and Subotica sand areas (40 and 32, respectively), while Fruska Gora Mountain and the Vrsac Mountains harboured the highest number of hoverfly species.

During May 2012 Diptera were sampled in the Serro do Courel area of Lugo Province, Galicia, northwest Spain. The authors of this paper, members of the Malloch Society (see website) are active in attempting to understand the detailed ecology of flies. Much of this work is through targeting larval stages often with an emphasis on saproxylic situations. By rearing adults from larvae direct relationships between them and their detailed habitat requirements are established. The list of nematocerous Diptera that were sampled includes 36 species two of them new to science and records of six others new to the Iberian peninsula are provided. We describe Lipsothrix galiciensis HancockHewitt sp. nov., and Prionolabis pjotri Hancock sp. nov. of the family Limoniidae and provide a key to adults of European Lipsothrix species. Such results from this brief opportunity indicate the potential of the area for further field work in these and other families of Diptera.

The syrphids (Syrphidae) of Serra do Courel, a mountainous locality of just over 20,000ha at the west end of the Cantabrian Mountains, northern Spain are poorly known. The Scottish based, Malloch Society visited the locality in May 2012 and collected a total of 462 specimens of 98 syrphid species and 36 genera. These represent the first syrphid records from Serra do Courel. The area has many meadows and small woodlands or 'soutos' and these habitats combined were the most productive, 69 spp. recorded. Cheilosia lucense Ricarte sp. nov. is described from Courel and compared with other species of the alpina group. Six other syrphid species were new to the Iberian Peninsula, three of which belong to the saproxylic genus, Brachyopa. In common with studies elsewhere in the Cantabrian Mountains, Cheilosia was the most diverse genus and 21 species were recorded. The syrphid fauna of the Cantabrian Mountains includes 203 species of which 24 are here added and a species checklist provided.

The results of the hoverfly (Syrphidae) collection by the ‘Malloch Society’ on the Greek island of Lesvos are presented.Fieldwork took place from February to March 2006 and from May to June 2010. An account of 66 species from 28 generais provided including two species new to science, five species new to Greece and data for several rarely recorded species.We describe Eumerus armatus Ricarte and Rotheray sp. nov., a medium size species with red abdomen. We also describe Sphiximorpha hiemalis Ricarte, Nedeljkovic and Hancock sp. nov., a hairy species with distinctive colour and pollinositypatterns and abdomen shape. The female of Eumerus claripennis Coe, 1957 is described and the male genitalia are figured.The majority of species encountered belonged to the typically Mediterranean genera Eumerus (8 spp.), Merodon (16 spp.)and Paragus (6 spp.). Approximately 71% of the recorded species also occur in Turkey. This supports the idea that West Mediterranean and Anatolian faunas overlap in Lesvos.
