V. Vigoni et al., Ultrastructural aspects of the reproductive morphology of Centropages typicus Kroyer, 1849 (Copepoda, Calanoida), CRUSTACEANA, 72, 1999, pp. 405-414
Ultrastructural studies have been conducted on the male and female of Centr
opages typicus to analyze spermatophore transfer mechanisms. Careful observ
ations have been made on the genital area of both sexes and of the mating a
ppendages in the male. In particular, a detailed description of the first t
wo somites of the female urosome is necessary to correctly interpret the st
rategies employed for positioning the spermatophore.
