The Maurit surveys along the Mauritanian coast revealed the small collection of thalassinideans examined in this work. A total of four species were identified, of which Ezaxius ferachevali n. gen., n. sp. is described and figured here. Calocaris macandreae Bell, 1853 is the most abundant species, while the presence of Calocarides coronatus (Trybom, 1904) is confirmed on the West African coast. ...

Twenty-three cases of deep mycoses were histologically diagnosed in 6500 surgical biopsy specimens examined during a three year period (1985-1988) in the Department of Pathology, University of Calabar Teaching Hospital, Calabar, Nigeria. These included 12 cases of African histoplasmosis, four of mycetoma, four of actinomycetoma, two of paranasal aspergilloma, and one of zygomycosis due to Conid...

Nymphs of Stenoscepa sp. feed on leaves of the Ni hyperaccumulator Berkheya coddii at serpentine sites in Mpumalanga Province, South Africa. These sites contain Ni hyperaccumulators, Ni accumulators, and plants with Ni concentrations in the normal range. We conducted studies to: (i) determine the whole-body metal concentration of nymphs (including those starved to empty their guts); (ii) compar...

Cytogenetic data for the genus Acromyrmex Mayr, 1865 are available, to date, for a few species from Brazil and Uruguay, which have uniform chromosome numbers (2n = 38). The recent cytogenetic data of Acromyrmex striatus (Roger, 1863), including its banding patterns, showed a distinct karyotype (2n = 22), similar to earlier studied Atta Fabricius, 1804 species. Karyological data are still scarce...

We describe a 61-year-old man who developed a mild gastrointestinal discomforts including diarrhea associated with feces containing many larvae similar to rhabditiform larvae of Strongyloides stercoralis diagnosed finally as Diploscapter coronata, a free-living nematode. This case is unusual infection in human and there are a few reports of this worm as a real parasite. Microscopically, Diplosc...
