Folioquinpes chathamensis (Sars, 1905) sensu Ruehe (1914)

Laophonte chathamensis Sars, 1905 sensu Rühe (1914)

Original description.

Rühe (1914): 33; fig. 11 (♀ only).

Type locality.

South Africa, Western Cape Province, Cape Town, Muizenberg, Sandvlei; freshwater lake.

Body length.

470-670 μm (♀) [ Rühe 1914].

Remarks.

Rühe’s (1914) illustrations are limited to the P5 and the abdomen in dorsal aspect. Differences with F. chathamensis include the distinctly longer caudal rami, the reduced pleural extensions on the abdominal somites, and the setae on the P5 baseoendopod being distinctly longer. Rühe (1914) suspected that Sars (1905) had misinterpreted the apical blunt spine on the P5 exopod as a single element rather than two adjacent ones. Mielke’s (1981) illustration, which confirms Sars’s observation, indicates that the space between the two apical spines in Rühe’s fig. 11b is in reality the inner core of the basally dilated spine. We suspect that Rühe has misinterpreted as a real phenomenon what he has seen only in optical section. Pending the discovery of fresh material the Western Cape population attributed to Folioquinpes chathamensis is here regarded as a species inquirenda in the genus.
