Phaenocora sp.? Ehrenberg, 1836

(Fig. 2 E)

Locality. Doñana National Park, Provincia de Huelva, Spain (36°54’50”N, 6°17’48”W). La Montaña del Rio: green algae in shallow brackish pool (06/04/2008).

Material. Two drawings of live animals. One whole mount and three serially-sectioned specimens, two of poor quality and one juvenile.

Remarks. The frontal position of the barrel-shaped, obliquely forward-slanting pharynx, the crenulate posterior end of the body and the separate openings of the protonephridia indicate that this species probably belongs to the taxon Phaenocora Ehrenberg, 1836 ( Phaenocorinae Wahl, 1910). Since the genital system could not be observed, a definite identification was impossible.
