Characiellopsis is a genus of green algae in the family Characiaceae. Two species are known: Characiellopsis anophelesii and Characiellopsis skujae.[1]

Description

Characiellopsis consists of solitary cells that are elongate and attached to a substrate via a pad of mucilage. Cells contain a single central nucleus. Young cells contain a single chloroplast, while older cells contain multiple; each chloroplast has a single pyrenoid. Cells reproduce by 2-flagellated zoospores. These zoospore escape from the tip of the mother cell via a tear in the mother cell's wall.[2]

Species

Characiellopsis anophelesii consists of solitary cells that are attached to mosquito (Anopheles) larvae.[2]

Characiellopsis skujae consists of solitary cells that are elongated to ovoid, attached to a surface via a thick stalk. The cell walls are very thick, and the tip of the cell has a refractive ring-shaped structure visible in light microscopy. Cells contain a single chloroplast filling the cell, each with a single pyrenoid. The apical ring structure is very distinctive, and it shares this characteristic with another taxon, Characium obtusum; the two species are probably synonymous.[3]
