Three new species of phytoseiid mites from Kenya (Mesostigmata: Phytoseiidae)

1978

The following 13 species of predacious mites of the family Phytoseiidae are recorded from various plants in Kenya: Amblyseius albizziae sp. nov., A. kenyae sp. nov., A. natalensis Van der Merwe, A. lokele Pritchard & Baker, A. largoensis (Muma), A. rykei Pritchard & Baker, A. teke Pritchard & Baker, Typholdromus kikuyuensis sp. nov., T. magdalenae Pritchard & Baker, Phytoseius amba Pritchard & Baker, p. ferox Pritchard & Baker, Iphiseius degenerans (Berlese), I. gongylus Pritchard & Baker. The new species and the male of A. natalensis are described.

Considerations on systematics of the Phytoseiidae (Acari: Mesostigmata), with definition of a new species group and description of a new species

2015

The authors debate some aspects of the classification of the Phytoseiidae, especially the subfamily Typhlodrominae. Within this taxon, the rhenanus group is the most numerous species group of Typhlodromus (Anthoseius), with 206 nominal species. Detailed observation of morphological characters of the species in this group showed a considerable variation, suggesting the presence of different natural lineages. The discovery of the new species here described, Typhlodromus (Anthoseius) sandrae Ragusa & Tsolakis n. sp., allowed the definition of the new porathi species group. Definition of the new species group, a dichotomous key as well as the description of the new species are given.

Fatty Acid Composition in the Lipids of some Marine Chiorococcales and Eustigmatales

1989

Abstract The fatty acid composition in the lipids of six coccoid microalgae species (≈ 2 μm in diameter) was investigated. In addition to analyses of ultrastructure and pigment content, lipid composition is shown to be a chemotaxonomic tool in the classification of algae. The four species of Chiorococcales (Chlorophyceae) - the marine species as well as the fresh water species, both kept in artificial seawater - contain a fatty acid composition resembling that of Chlorella spp. and of green leaves of higher plants. The fatty acid pattern is characterized as lacking in C20 acids but containing large amounts of C 16 and C 18 polyunsaturated fatty acids, hexadecatrienic acid (16 :3) and a-lino…

Typhlodromips jurmoensis ; (Acari: Mesostigmata: Amblyseiinae), a new species from the archipelago of SW Finland

2014

A new species belonging to the genus Typhloromips De Leon, 1965 is described. It was collected from Calluna moorland soil on Jurmo, a remote island in the SW archipelago of Finland. Typhlodromips herbarius (Wainstein, 1960) is considered a senior synonym of T.tenuis (Westerboer, 1963), syn.n. A key is given to related species with a similar spermathecal structure. peerReviewed
