Choeradoplana cyanoatria is a species of land planarian belonging to the subfamily Geoplaninae.[1] It is known from specimens found in General Carneiro, Brazil.[2]

Description

Choeradoplana cyanoatria is a flatworm around 20โ€“28 mm in length and 3โ€“4 mm in width. It has an elongate body with parallel margins. The head, or cephalic region, has two glandular cushions on the ventral side, separated by a median slit. The front end of the body is expanded, while the back end is slightly pointed. The dorsal side of the body is a yellowish base color, covered densely by small and irregular dark brown flecks. The yellowish base is visible on the head and margins, as well as on a longitudinal median stripe that runs down the front half of the body aside from the head. The ventral side is a pale yellow color.[2]

It is distinguished from other members of Choeradoplana by its dark brown flecks, a bell-shaped pharynx, sperm ducts that open subterminally into the prostatic vesicle, an oval-elongate, folded prostatic vesicle that becomes funnel-shaped proximally and forms an elongate duct inside the penis papilla, and a conical, long, almost symmetrical penis papilla with a posteriorly-shifted dorsal insertion that fills the entire atrium.[2]

Etymology

The specific epithet is derived from the Latin words cyano ("blue") and atria ("atrium"), in reference to an abundant secretion of cyanophils from an opening in the species' atrium.[2]
