Descriptions and illustrations of some new and poorly known turrids of the tropical northwestern Atlantic. Part 1. Genera Buchema Corea, 1934 and Miraclathurella Woodring, 1928(Gastropoda: Turridae: Crassispirinae)

摘要

Descriptions and illustrations are presented for four small, less than 12 mm in length, crassispirine turrids from the southeastern Caribbean, three in the genus Buchema Corea, 1934 and one in Miraclathurella Woodring, 1928. One of the three Buchema is described for the first time. The other two, Buchema bellula (E.A. Smith, 1882) and Buchema primula (Melvill, 1923), are redescribed because they are relatively unknown, and lack published photographs and adequate description. Their identification is compounded by the existence of a hitherto undescribed small Buchema that is similar in appearance, Buchema nigra new species, and by similar looking small Crassispira in the subgenus Monilispira Bartsch and Rehder, 1939 that will be addressed in a later paper. The fourth small crassispirine, Miraclathurella peggywilliamsae new species, is only the second known member presently placed in this genus in the tropical northwestern Atlantic. Variation in form of the four species is described.
