| Cheilosia griseiventris sensu Stubbs & Falk (1983) new to the Netherlands (Diptera: Syrphidae) Although already recognized as a distinct species in Britain by Stubbs & Falk (1983), other authors have treated Cheilosia griseiventris (Zetterstedt, 1843) as a (possible) synonym of C. latifrons Loew, 1857. Unpublished taxonomic results indicate that these taxa should be considered as separate species, but also that there may be more than two European species involved. So possibly the name griseiventris is not applied correctly. However, until the taxonomy of the latifrons-complex is fully resolved, we use the name griseiventris. The nine specimens from the Netherlands agree with the British specimens of C. griseiventris. Based on these... |

| Three species of hoverflies removed from the Dutch list (Diptera: Syrphidae) Doubtful records of three hoverfly species from the Netherlands are discussed. Two specimens previously identified as Cheilosia acutilabris Becker, 1894 belong to C. proxima (Zetterstedt, 1843). Five specimens previously identified as Melangyna ericarum (Collin, 1946) belong to M. umbellatarum (Fabricius, 1794). Four species previously identified as Paragus finitimus Goeldlin de Tiefenau, 1974 are now considered to belong to P. bicolor (Fabricius, 1794). These results lead to the conclusion that Cheilosia acutilabris, Melangyna ericarum and Paragus finitimus should be removed from the Dutch species list. |

| Faunistics and ecology of the syrphid genus Epistrophe in The Netherlands (Diptera: Syrphidae) Ten species of Epistrophe have been found in the Netherlands, two of which, E. cryptica and E. similis, are recorded here for the first time. The distribution, changes in distribution and ecology of the species were investigated and are illustrated by distribution maps and diagrams of the flight period. In all species, except E. eligans, females were observed more than males. Furthermore, females seem to be active later in the season than males. It is discussed that this is probably caused by the differences in behaviour between the males of the species. |

| New and rare hoverflies for the Dutch fauna (Diptera: Syrphidae). Paragus albifrons (Fallén), P. bicolor (Fabricius), Sphegina verecunda Collin, Neoascia annexa (O.F. Müller), Callicera aenea (Fabricius), Cheilosia caerulescens (Meigen), C. chloris (Meigen), C. flavipes (Panzer), Chamaesyrphus scaevoides (Fallén), Xylota coeruleiventris Zetterstedt, Merodon rufus Meigen and Eristalis picea (Fallén) are recorded with full details for the first time from The Netherlands. Some of these species have been listed by other authors but without any details. Here additional notes are given on the distribution and biology of these twelve species as well as 49 other more or less rare species. |

| Changes in ranges of hoverflies in the Netherlands in the 20th century (Diptera: Syrphidae) In July 2001 the database of the Netherlands Syrphidae Recording Scheme contained approximately 200 000 records of Syrphidae. This database was used to examine changes in the hoverfly fauna of the Netherlands during the 20th century. The dataset was divided into two parts, before and since 1988, containing equal numbers of records. This revealed that there is a significant increase in the distribution of hoverfly species with saproxylic larvae. Probably this is a consequence of the changes in woodland management that have taken place in the past 20 years. Another result of the trend analysis is the conclusion that there is a high proportion of southern species... |

| Surimyia, a new genus of Microdontinae (Diptera: Syrphidae) is described, based on specimens from Suriname. Surimyia is the only known genus of Syrphidae in which the katatergum (ventral part of lateral postnotal sclerite of mesonotum) lacks microtrichia. Within Microdontinae, the genus is unique in the absence of pilosity on the postpronotum. It is also remarkable in the presence of strong, black setae on thorax and abdomen, a character rarely found in Syrphidae. The genus is superficially similar in external morphology and colouration to Paragodon Thompson, 1969, but clearly different in the characters mentioned above, as well as in the structure of the male genitalia. Two species are assigned to Surimyia: S. minutula (van Doesburg, 1966) and S.... |

| The 'real' Brachyopa dorsata in the Netherlands after 39 years (Diptera: Syrphidae) The hoverfly Brachyopa dorsata Zetterstedt, 1837 was already mentioned for the Netherlands by Van Aartsen (1970), based on a specimen from 1968, which later proved to belong to B. panzeri Goffe, 1945. On April 21, 2007, a male B. dorsata was collected from the flowers of Prunus padus in the north-western part of the Veluwe. The locality is part of a large mixed forest complex, dominated by old beeches. This is the first record of B. dorsata for the Netherlands. The species was expected, for it is known from a small number of localities in adjacent parts of Germany. |

| For the first time a gregarious parasitoid belonging to the genus Phaenocarpa Foerster, 1862 (Braconidae: Alysiinae) is reported, and described as P. helophilae spec. nov. from England. The first record of Chloropidae as host for a Phaenocarpa species is given; P. livida (Haliday, 1838) reared from Calamoncosis (Rhaphiopyga) glyceriae Nartshuk, 1958. Sathra debilis Foerster, 1862, is synonymised with P. livida (Haliday). Additionally, Phaenocarpa curticauda spec. nov. from The Netherlands is described and fully illustrated. A lectotype is designated for Alysia pectoralis Zetterstedt, 1838, and Phaenocarpa rufoflava Papp, 1968, is recognised as a valid species. |
