| A new species of Gammarella Bate, 1857 is described from shallow water, inhabiting the interstitial system in soft bottoms of the Chafarinas Archipelago (western Mediterranean, N. Africa). The relationships of Gammarella with the genera Nuuanu and Cottesloe are briefly discussed. Numerical taxonomie methods are utilized to differentiate between the morphologically related species and the intermediate species. In a table the principal differentiating characters of Gammarella species are presented. Gammarella garciai n. sp. is characterized by its intermediate position between Gammarella, Nuuanu and Cottesloe, showing an intergradation of characters. Gammarella garciai n. sp. and G. merringannee show ecologically intermediate characters between the larger... |
