Abstract
New sex associations are proposed for four species of Darditilla: Darditillaamabilis (Gerstaecker, 1874); Darditillabejaranoi Casal, 1968; Darditilladebilis (Gerstaecker, 1874); and Darditillafelina (Burmeister, 1854). Darditillabotija Casal, 1965, syn. n. is the male of Darditillaamabilis; the other three males were previously unknown. Mutilladecorosa Kohl, 1882, syn. n. is conspecific with Darditillafelina. Descriptions and extended diagnoses are provided for previously unknown males and for females that were not adequately described. These represent the first sex associations for the genus Darditilla.
