Abstract - A new genus Apicystis and a new combination Apicystis bombi (Liu, Macfarlane & Pengelly) is proposed for a neogregarine parasitic on Bombus spp and Apis mellifera. The genus Apicystis is characterized by having navicular oocysts containing only four sporozoites and basically differs from the genus Mattesia which has spindle oocysts with eight sporozoites. This parasite was recorded in ten species of Bombus in Europe and North America, but has been observed only once in Apis mellifera in Finland.

Key words: Apicystis / Apis / Bombus / new genus / protozoan / parasite

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.

An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account.
    In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see You should disable this module if you wish to use the OpenURL server that you or your library have defined.
