TERRESTRICYTHERE SP.   ( FIGS 22 View Figure 22 , 23 View Figure 23 )

Material examined

One adult male, with soft parts dissected in polyvinyl lactophenol stained with methylene blue and sealed in a glass slide, and valves stored in a cavity slide (2003.1049); collected from a marine intertidal rockpool at Gore Point, Porlock Bay , on the southern shore of the Bristol Channel , 51∞14¢N, 3∞37¢W, on 9 March 1978   .

Remarks

Our specimen undoubtedly represents a fourth, hitherto undescribed species of Terrestricythere   , but we consider it advisable to leave it in open nomenclature until additional material becomes available for a full description. The carapace shape is similar to that of the other Terrestricythere species   but does not quite match any of them in lateral outline; relative to its length it is slightly less high than either T. elisabethae   or T. pratensis   , but slightly higher than T. ivanovae   . The appendages are similar to those of other Terrestricythere species   , the only significant differences being noted in the L7 and the hemipenis ( Fig. 7 View Figure 7 ). The An1 has five articulated podomeres, as in T. elisabethae   and T. pratensis   . The L7 is most similar to that of T. elisabethae   , bearing one long and one short-terminal claws, in contrast to the one long and one medium length claws of the two Russian species. The larger distal process of the hemipenis has an anvil-shaped protuberance on its outer edge ( Figs 7 View Figure 7 , 23 View Figure 23 ), similar to that seen in T. pratensis   , but with rounded rather than pointed extremities.
