Phoenocora megalops   (incorrect subsequent spelling) Cognetti de Martiis 1916: 217, 233, 235, 237.

Known distribution: Montpellier? ( France), in ditches with pluvial waters ( Duges 1830); Tartu (former Dorpats, Estonia) ( Braun 1885), South France?, Tartu ( Estonia) ( Graff 1909; Graff 1913), Finland ( Nasonov 1917; Luther 1918), vicinity of Berlin ( Germany) ( Weise 1942); in the vicinity of Hamburg ( Deutschland), along the Elbe estuary (see Müller & Faubel 1993 for localities and references).

According to Braun (1885) the animals are up to 4 mm long, with kidney-shaped eyes, which appear red or silver under reflective light and black under transmissive light. Zoochlorellae are absent. The male copulatory organ is probably of the duplex-type IIA (see COMPARISON OF SPECIES section). The female genital system is so poorly known that it is impossible to determine the type. Further observations on new material are needed. The distribution in France recorded by Duges (1830) and Graff (1909; 1911) is questionable since the early descriptions of P. megalops   were not very adequate, and could also fit some of the later-described species of the taxon Phaenocora   .
