Harvey, Alan W.2005-10-062005-10-061999http://hdl.handle.net/2246/309832 p. : ill. ; 26 cm.Includes bibliographical references (p. 31-32)."Two new species of the porcelain crab genus Clastotoechus Haig are described from the tropical eastern Pacific Ocean: C. hickmani, from the Galápagos Islands and Malpelo Island, and C. lasios, from Jalisco, Mexico. Both species have been confounded with C. diffractus Haig in the literature. C. lasios is in fact closely related to C. diffractus, but C. hickmani is most closely related to the Atlantic C. nodosus (Streets). In addition, the Atlantic C. vanderhorsti (Schmitt) is placed in a new genus, Madarateuchus. M. vanderhorsti and all five species of Clastotoechus s.s. are described (or redescribed) and illustrated, and a key is provided to differentiate among these taxa"--P.
