| Notes |
Diagnosis: Antedoninae with cirri short and stout, strongly recurved distally. First pinnule with 18-35 pinnulars; pinnulars no more than twice as long as broad. Second pinnule slightly longer than first; third similar to succeeding genital pinnules. [details] Taxonomic Remark: “I am doubtful whether the Japanese minuta can be considered as congeneric with the South African occidentalis. The former does have similar short cirrus segments, but so also do two other Japanese species of the Antedoninae, Andrometra psyche and Antedon (formerly Compsometra) serrata. Also, in genera such as Antedon, the included species show a wide range of proportions of the longest cirrus segments from one and a half times to six times as long as broad. This character is therefore of little significance in determining the genus. The rather short segments of P1, however, may be of more importance in allying minuta and occidentalis. Those of minuta (18 in the holotype) are about half again as long as wide but in occidentalisthe 30 to 35 segments are unique in the Antedoninae in not being longer than wide (fig. 66, p. 95). In some species of Antedon and Mastigometra, however, the pinnule segments are little longer than they are in minuta. I also consider the geographical separation of the two species to be another factor against their being congeneric.” [AM Clark IN Clark AH & Clark AM (1967), p. 92] [details] | ||||||||||||||||
