Limnias myriophylli ( Tatem, 1868)

Fig. 3A

Limnioides myriophylli Tatem, 1868

Limnias myriophylli (Tatem) : Western, 1891

Types: None designated.

Type locality: No locality indicated.

Diagnosis. Tube straight to slightly curved; base clear, abruptly changing to obscure to which debris adheres. Dorsal gap in corona slightly less than neck width. Ventral antennae long. Dorsal nodules present (n=2). Amictic, male, and diapausing embryos undescribed.

Measurements: Tube length ~340 µm; extended animal ~460 µm.

Comments. The etymon of this genus was not discussed by Tatem (1868). No type location is reported by Tatem (1868). Western (1891) discussed problems with Tatem’s descriptions, offering the conclusion that the species Tatem described was a Limnias rather than a representative of the genus Limnioides . However, Western’s record of Limnias myriophylli from an undefined location in Oxshott, U.K. is most likely erroneous.
