Eudactylota

Eudactylota Manfredi, 1927

ref. ID; 2597

There appears to be some confusion regarding the name of this genus. Gallagher (1957) proposed Manfredium, which is also used in the new edition of Ward and Whipple (1959). The name Manfredium may not be valid (personal communication of Dr. W.T. Edmondson). (ref. ID; 2597)

Descriptions

The head is smaller, and the body of the living animal plumper. The toes, swollen at the upper end, are exactly equal in length. The method of locomotion is usually by quiet swimming, the animal spreading its toes quite often, rarely jumping. (ref. ID; 2597)

Measurements

Length of head and body 190; greatest diameter 114; foot 74; toes 265 µm. In general it is much smaller than described by Wulfert or Lucks. (ref. ID; 2597)

Comments

Hauer (1965) described a new species (Eudactylota wulferti) from The Parana do Xiborena after a contracted specimen. Koste (1972) also found animals with preservation artifacts in samples from Amazonia which he thought to be the new species described by Hauer. Some specimens hardly deformed by preservation from the Nhamunda-area permit a comparison with the animals of the species-group described in detail by Wulfert (1940). We could only find differences in size but not in morphology or anatomy. Therefore we suggest Eudactylota wulferti Hauer, 1965 to be a modification of Beauchampiella eudactylota (the first segment of the foot seen by Hauer belongs to the body!). (ref. ID; 2834)
