Arenopontia subterranea Kunz, 1937 sensu Cottarelli (1975)

Cottarelli (1975: 69–70; Figs 12 , 17 , 20 ) illustrated the mandibular palp, P1 and ♀ P5 of a population from Riu Ciuchesu near San Teresa di Gallura in the Strait of Bonifacio (northern Sardinia, Italy) which he assigned to A. subterranea . There is a remarkable similarity in P5 structure (vestigial 5th seta along the distal margin; proportional setal lengths) with Mielke’s (1975) Isle of Sylt material but the P1 endopod is shorter than in the type population (enp-1 5.9 times as long as wide; enp-1:exp ratio 1.27), resembling the condition in A. anatolica sp. nov. The ornamentation of the P1 endopod confirms placement in Group I but in the absence of information on the caudal rami and remaining swimming legs the true identity of Cottarelli’s (1975) material remains to be confirmed.
