Phaenocora chloroxantha Marcus 1946: 71 , 74, 77–81, 82, 165, 166, Figs 85–87, 92–93; Karling 1956: 195, 199 Fig. 5 ; Marcus & Marcus 1959: 19; Noreña et al. 2004: 234.

Known distribution: Canindé (São Paulo, Brazil); in a small stagnant lake near Limão (São Paulo, Brazil) along the river Tietê ( Marcus 1946).

Material examined: None.

Diagnosis: Animals about 2–3 mm long, with a general body form resembling a smoothing iron. Visible eyes absent. Two types of zoochlorellae present, small round ones and long ones. Male copulatory organ probably of the duplex-type IIIA. The area where the vasa deferentia enter the seminal vesicle is ciliated. Female genital system of the TYPHLOPS - type. No connection with the gut. With a female genital canal, a small intestinal bursa and a duct that runs towards the gut and resembles the burso-intestinal duct of other species of Phaenocora .
