Difflugia venusta (Penard, 1902)

Diagnosis: shell outline smooth, pyriform, with an elongated neck, sharply pointed in the aboral region; shell composed of small to large pieces of flat quartz, plus occasional diatoms.

Dimensions: Penard gives no dimensions. My measurements c. 150 um.

Ecology: aquatic plants, debris.

Remarks: Penard describes this species as a characteristic variety of Difflugia pyriformis. His specimens always had zoochlorellae.
