03BE87D2FFB1EE63FF286FDBFC4EFDD7.taxon	materials_examined	Type species. Orchestia spinifera Mateus, 1962, original designation. Included species. Africorchestia includes 5 species: A. fischeri (H. Milne Edwards, 1830); A. quadrispinosa (K. H. Barnard, 1916); A. skoogi (Stebbing, 1922); A. spinifera (Mateus, 1962); A. tricornuta (Shoemaker, 1920). Remarks. Africorchestia appears to be most similar to Americorchestia Bousfield, 1991 and Sardorchestia Ruffo in Tafani et al., 2004. Americorchestia and Africorchestia are similar in most characters including the male parachelate first gnathopods and the characteristic third uropods with the ramus longer than the peduncle. They differ in the pleosome which is sculptured in Africorchestia, in pereopod 6 which is sexually dimorphic in Africorchestia, and in the dactyli of pereopods 6 and 7 which have slender setae along the posterior margin in Africorchestia. Africorchestia is also very similar to Sardorchestia. They differ significantly in the dactyli of pereopods 6 and 7 with setae along the posterior margin in Africorchestia (absent in Sardorchestia); in pereopod 6 which is sexually dimorphic in Africorchestia; and pleonites 1 – 3 rugose or with spines (absent in Sardorchestia).	en	Lowry, James K., Coleman, Charles Oliver (2011): Africorchestia a new genus of sand-hoppers (Crustacea: Amphipoda: Talitridae) from western Africa and south-western Europe.

03BE87D2FFB3EE63FF286AB8FE18F90E.taxon	discussion	Remarks. Based on the one habitus illustration of A. fischeri (H. Milne Edwards, 1840) the species has a unique pleonite dorsal spine formula, a unique large mid-palmar protuberance on the male gnathopod 2 palm and an enlarged oval-shaped basis on the male pereopod 6 not shared with any other species of Africorchestia. These characteristics indicate a very distinctive species, however the lack of type material, the lack of a type locality and the lack of morphological detail in the habitus illustration makes O. fischeri a puzzling species.	en	Lowry, James K., Coleman, Charles Oliver (2011): Africorchestia a new genus of sand-hoppers (Crustacea: Amphipoda: Talitridae) from western Africa and south-western Europe.
