Abstract

This study provides a comprehensive account of Nosema canburensis sp. nov., a newly discovered microsporidian species from the Italian striped bug, Graphosoma italicum Müller (Hemiptera: Pentatomidae), including its morphological, ultrastructural, and molecular phylogeny. The sporogonic proliferation of the current microsporidium occurs by binary division and usually results in chain formation as in Nosema members. The mature spores are ovoid/ellipsoidal in shape with an average length of a 4.44 ± 0.57 μm (3.48-6.55; n= 100, fixed) and a width of 2.27 ± 0.23 μm (1.67-2.92; n=100, fixed). The microsporidiosis is systemic, but the infection level is highest in the mid-gut of adult samples. The mature spores have isofilar polar filaments that make 10-11 coils. There is a difference in size between the anterior coils and the distal coils. The distal coils, which formed a triangle, were arranged in groups of three and located in close proximity to the center of the posterior part of the mature spores.

期刊介绍： Systematic Parasitology publishes papers on the systematics, taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic), Monogenea, Digenea, Cestoda, Acanthocephala, Aspidogastrea, Cestodaria, Arthropoda (parasitic copepods, hymenopterans, mites, ticks, etc.), Protozoa (parasitic groups), and parasitic genera in other groups, such as Mollusca, Turbelleria, etc. Systematic Parasitology publishes fully illustrated research papers, brief communications, and fully illustrated major revisions. In order to maintain high standards, all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that, in some cases, this may cause problems for the authors, but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa, and the types will be preserved for posterity.
