Nueva especie de Paralomis en aguas de Chile: Paralomis chilensis n. sp. (Crustacea, Anomura, Lithodidae)

Abstract

A new species of Lithodidae: Paralomis chilensis n. sp. is described and ilustrated. P. chilensis is related to P. aspera F axon, but it differs from it in some characteristics such as: P. chilensis shows a naked rectangular depression which is also absent in P. longipes Faxon; the segments of the walking legs are densely covered by longitudinal rows of spines with a ring of stiff setae near the tip, in the figure of P. aspera (in F axon, 1895) the merus present a longitudinal strip devoided of spines. P. chilensis differs from P. papillata (Benedict) and P. inca Haig in the presence of spiniform tubercles that covered thickly carapace and abdomen, each encircled by a ring of stiff setae. P. chilensis and P. granulosa (Jacquinot) , from southern Chile, make up the only Paralomis species from Chilean waters and P. chilensis with Glyptolithodes cristatipes (F axon) and Lithodes murrayi Henderson are the only three lithodids recorded from deep waters off Central Chile.
