A redefinition of the morphology, range and relationship of Tropodiaptomus schubotzi van Douwe syn Tropodiaptomus incognitus Dussart Gras and of Tropodiaptomus symoensi Einsle, with notes on Tropodiaptomus loveni de Guerne Richard


, : A redefinition of the morphology, range and relationship of Tropodiaptomus schubotzi van Douwe syn Tropodiaptomus incognitus Dussart Gras and of Tropodiaptomus symoensi Einsle, with notes on Tropodiaptomus loveni de Guerne Richard. Revue d'Hydrobiologie Tropicale, 201: 3-12

The true identity of Tropodiaptomus schubotzi is established. Its range covers the Chari basin, including Lake Chad Africa , where it has been extensively studied under the name Tropodiaptomus incognitus. In the oasis of Kufra in Libya, a relict population of Holocene age occurs which shows some amount of speciation, and is described as T. s. kufraensis n. ssp. Its nearest relative is T. symoensi which occupies the south-east of the Zaire basin. It is separated from T. loveni (De Guerne & Richard), known only from the lower Zaire basin, by the inundated forest zone of the middle Zaire. The relationship between these two Zairian species is rather distant although both belong to the same species-group, that of T. orientalis. T. schubotzi vicariates with T. kraepelini in the East. T. symoensi shows partial overlap with T. kraepelini in the south-east of the Zaire basin. Whether T. symoensi also overlaps or vicariales with other members of the T. loveni-T. kraepelini group, such as T. kissi and T. kieferi, is still uncertain, vicariates with other members of the T. loveni-T. kraepelini group, such as T. kissi and T. kieferi, is still uncertain.

The acute-phase protein C-reactive protein (CRP) recruits C1q to the surface of damaged cells and thereby initiates complement activation. However, CRP also recruits complement inhibitors, such as C4b-binding protein (C4bp) and factor H, which bot...
