Kotov, Alexey A. & Ferrari, Frank D., 2010, The taxonomic research of Jules Richard on Cladocera (Crustacea: Branchiopoda) and his collection at the National Museum of Natural History, U. S. A., Zootaxa 2551 (1), pp. 37-64 : 52

25. Macrothrix chevreuxi Guerne et Richard, 1892

Macrothrix Chevreuxi Guerne and Richard 1892c, p. 530 –533, figs 3–6.

Type locality. " Rio Fresco , près Rufisque " and "un lieu dit "Caca Muerca", près Majumba", (Richard 1892c). The former now is in Senegal ; the latter now is in Gabon.

Richard's specimens. A few females from samples DGF 854 from “Fr. Eq. Africa” (no further information).

Samples DGF 855 and DGF 865 from “Caca Muerca. Fr. Eq. Africa” do not contain this taxon. Samples DGF 708 and DGF 883 from “Mayoumba. Congo, Fr. Eq. Africa” are no longer in the collection but did not contain Macrothrix sp. according to David Frey’s card. There are no Macrothrix in any of the samples from Senegal.

Comments. A junior synonym of M. triserialis according to Smirnov (1992). However, Dumont et al. (2002) and Kotov et al. (2004) believe that specimens reported as " M. triserialis " constitute a large assemblage of sibling species. The status of different African populations of M. cf. triserialis should be reconciled with specimens from type locality.
