Marine Amphipods from Pantelleria and Catania (Sicily)

During two stays, in 1970 and 1973 at Pantelleria and Catania, a total of 48 samples from algae and sand were collected yielding 90 species of Amphipoda. Systematic problems were posed by the following species: Gammaropsis cf. erythrophthalma, Gammaropsis n. sp., Lysianassa pilicornis, Microjassa cumbrensis, Micropythia carinata, Panoploea minuta, and Photis longipes. Panoploea and Lysianassa are figured here. The generic name Micropythia nom. nov. is proposed for Pythia Krapp- Schickel, 1972, nec Bolten, 1798. Faunal successions on three algae-covered slopes near Catania are analyzed. Two diagrams give ecological information: a matrix of homogeneity of those samples taken in 1970 having a high mutual homogeneity, and a schematical succession of the biotopes where algae were sampled along a slope on the coast of the islet of Lachea, with their respective interrelationships.
