| In the Netherlands, usually only one Leucanthemum species is recognised, L. vulgare Lam. Recent field observations suggest that the Leucanthemum species that occurs abundantly in the Netherlands is the tetraploid species L. ircutianum DC instead. A few Dutch specimens in the herbarium collection of Naturalis in L, however, have been identified as belonging to the 'true' diploid L. vulgare. The latter seems to be rare in the Netherlands, and might be confined to a few relict populations. In Nederland word slechts één Leucanthemum-soort onderscheiden die hier bekend staat onder de naam L. vulgare Lam., een diploïde soort. Op basis van veldobservaties moet echter worden geconcludeerd dat de algemeen voorkomende Margriet in Nederland waarschijnlijk de... |

| As most of the sea bottom in the Dutch part of the North Sea consists of sand, marine fauna that live in association with hard substrates are rarely monitored. We report here on the results of a species inventory in June 2011 done by scuba-diving while focusing on a wreck on the Dogger Bank and on rocky bottoms on the Cleaver Bank. This resulted in various new records of species for the Dutch part of the North Sea. This result appeared for a large part linked to the added value of monitoring with scuba-divers. It is therefore concluded that scuba-divers should be used in addition to the more traditional monitoring methods in which dredges and grabs are used, if one aims at getting an accurate view of the biodiversity present in marine regions like the... |

| New and interesting Microlepidoptera from the Netherlands, mainly in 1984. The following species are recorded here for the first time from the Netherlands: Trifucula maxima Klimesch, Leucospilapteryx omissella (Stainton), Argyresthia (Blastotere) trifasciata (Staudinger) , Teleiodes wagae (Nowicki), Chionodes tragicella (Heyden), Gelechia muscosella Zeller, Epinotia thapsiana (Zeller) and Celypha rosaceana (Schläger). Monochroa niphognatha Gozmány has also been recorded for the first time, but was misidentified previously in our country as M. tetragonella Stainton. The fist authentic Dutch specimen of the latter species is recorded her now. Bucculatrix antispilella Spuler is removed from the Dutch list. The known distributions of five Tinaeidae in the... |

| The common NE Atlantic sponge species hitherto known under the name Prosuberites epiphytum (Lamarck, 1814), is differentiated from the South Australian type and other regional specimens. Spicule size and form, although generally similar, are subtly different. Australian P. epiphytum apparently persistently overgrow the thallus of algae, possibly as part of a symbiotic association, and this is not known for European specimens. In view of these facts and taking into account the disjunct distribution, it is proposed to assign the NE Atlantic populations to a new species. The genus Prosuberites has been restricted recently to species with single long tylostyles with heads embedded in a basal spongin plate, and both P. epiphytum and the new species do not... |

| The relative sensitivities of 309 common invertebrate species in Dutch marine waters are presented for environmental and anthropogenic pressures like organic enrichment, sedimentation and fisheries. The species were furthermore appointed to trophic groups like suspension and deposit feeders. The Dutch Ministry of Infrastructure and the Environment uses these data when calculating the Benthic Ecosystem Quality Index 2 and the Infaunal Trophic Index. These metrics aid in the mandatory monitoring of ecological quality for example for the European Water Framework Directive. The common Dutch species were selected based on their abundance according to, 1. the mwtl dataset including results of on-going monitoring programs issued by the Ministry, 2. the... |

| The European species of the subgenus Aliolus Say, 1836, of the genus Eubazus Nees, 1814, and of the genus Dicyrtaspis van Achterberg, 1980 (Hymenoptera: Braconidae: Brachistinae) are reviewed. The identity of Triaspis thomsoni Fahringer, 1934, and the interpretation by S˘ noflák (1953) are discussed. A lectotype is designated for T. thomsoni, a neotype for the types species of Aliolus Say, 1836 (Bracon trilobatus Say, 1836) and T. thomsoni sensu Šnoflák is described as a new species (Eubazus nigroventralis spec. nov.) from Bulgaria, Germany and Czech Republic. Two new species of the E. lepidus-group are described and illustrated (E. punctifer cpec. nov. from Bulgaria and E. planifacialis spec. nov. from The Netherlands, Belgium and Sweden). In addition, a... |

| A total of ten crayfish species have been observed in the Netherlands: one native species (the Noble crayfish Astacus astacus) and nine invasive species. Six invasive species are established (narrow-clawed crayfish Astacus leptodactylus, signal crayfish Pacifastacus leniusculus, spiny-cheek crayfish Orconectes limosus, virile crayfish Orconectes , white river crayfish Procambarus acutus and red swamp crayfish Procambarus clarkii), the status of one invasive species (marbled crayfish Procambarus sp.) is currently unclear. Two invasive species (the stone crayfish Austropotamobius torrentium and the redclaw Cherax quadricarinatus) have been recorded only once. The remarkable expansion of some of these invasive crayfish has raised questions about the possible... |

| This is the twelfth compilation of interesting Microlepidoptera collected in The Netherlands, covering the year 1999. Cochylidia richteriana (Tortricidae) is recorded for the first time from The Netherlands: two females were swept from vegetation in the extreme south of the country. In 1999 Cameraria ohridella (Gracillariidae) appeared to be established in The Netherlands, we refer to its discovery. The following rare or interresting species are mentioned here: Ectoedemia quinquella (Nepticulidae), the second Dutch locality: the very rare Depressaria pulcherrimella (Depressariidae) was found in the province Zuid-Holland; a third locality of both Aristotelia subdecurtella and Monochroa arundinetella (Gelechiidae) for The Netherlands in the province of... |

| Bryozoa or moss animals constitute a conspicuous and species-rich component of hardsubstrate benthic communities in marine and estuarine habitats. To gain insight into the biodiversity of these habitats, knowledge of bryozoan species is indispensable. Since the last comprehensive publication on Dutch species in 2004 much new information has become available. Particularly from the Dutch part of the Continental Flat of the North Sea, the largest natural area of the Netherlands, many new records have been collected. Other reasons to present an updated review are changes in nomenclature, the arrival of some exotic species and identification issues. |

| A survey of the groundwater fauna of The Netherlands has revealed the presence of 4 species of Parastenocarididae, viz. Parastenocaris fontinalis Schnitter & Chappuis, 1915, P. tumida Kiefer, 1961, P. germanica Kiefer, 1936, and P. nolli Kiefer, 1938, the latter two being new for The Netherlands. P. tumida is only imperfectly known, but there is enough material so that a full description can now be given not only of the female but also of the male hitherto unknown. |

| 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... |
