Monanema joopi n. sp. (Nematoda, Onchocercidae) from Acomys (Acomys) spinosissimus Peters, 1852 (Muridae) in South Africa, with comments on the filarial genus

摘要: Monanema joopi n. sp. is described from blood drawn the heart of murid Acomys (Acomys) spinosissimus in South Africa. It characterised by a non-bulbous cephalic extremity, shared with only one its five congeners, and cylindrical tail caudal alae spicular ratio 2.7 male. As typical for genus, microfilariae are skin-dwelling. They 185 to 215 micrometres long have no refractory granules beneath their sheath. A key species presented an amended generic description, based on six currently known species, proposed. Species primarily lymphatic low intensity infection M. heart, might suggest that not all adults settle cavities. One also consider other, more susceptible rodents serve as hosts this parasite well. To date, geographic range includes North America, Africa Australia, each representatives different lineage. Given present hypotheses evolutionary origin subsequent migrations rodents, we expect be Palearctic-Oriental region.
