Spatiotemporal control of Cindr at ring canals during incomplete cytokinesis in the Drosophila male germline

► Cindr is a novel component of Drosophila male germline mitotic and meiotic ring canals. ► Cindr is lost from mitotic ring canals at the mitosis-to-differentiation transition. ► Cindr loss from mitotic ring canals marks a common step of Drosophila female and male gametogenesis. ► Anillin recruits Cindr to the contractile ring during meiotic cytokinesis
