Abstract

Frontal knob morphology of a few specimens of Artemia salina from Lymington, England, kindly provided by Dr. Boxshall (British Museum of Natural History, London), was examined by means of scanning electron microscopy in order to make comparisons with recently described morphology of North African (Sfax and Mégrine, Tunisia) and Italian (Tarquinia, Latium; Sant'Antioco, Carloforte, Cagliari, and Su Pallosu, Sardinia) populations, respectively, referred to as A. tunisiana and A. salina (Mura, Del Caldo, and Fanfani, 1989; Mura, Fanfani, and Del Caldo, 1989). As to the shape of the frontal knobs and to their ornamentation, these species can hardly be separated one from another. Possible conspecificity is suspected, thus confirming data obtained by other authors with a series of cross breeds (Clark and Bowen, 1976; Baratelli et al., in press). New data concerning the sample from Lymington suggest that this population is conspecific.
