Kaczmarek, Łukasz, 2017, Annotated zoogeography of non-marine Tardigrada. Part IV: Africa, Zootaxa 4284 (1), pp. 1-74 : 30

75. Acutuncus antarcticus ( Richters, 1904d) sensu lato [T/F]

Hypsibius cf. antarcticus (Richters, 1904) ( Van Rompu et al. 1991a)

Terra typica: Gaussberg, Wilhelm II Land ( Antarctica)

Tanzania:

• 03°17′S, 37°31′E; ca. 1,500 m asl: Kilimanjaro Region, Kilimanjaro National Park, Marangu gate, rain forest, below tree line, river benthos sample . Van Rompu et al. (1991a)

Record numbers. Tanzania: 1; total: 1.

Remarks. The description in Van Rompu et al. (1991a), was based on a single specimen displaying a deformed pharyngeal bulb with the macroplacoids and microplacoid situated towards the anterior of the bulb. Such a description had been thought to indicate the species ‘ antarcticus ’ but was subsequently recognised as either pre-simplex form or a mounting anomaly ( Dastych 1991). The presence of a microplacoid indicates this was not Acutuncus antarcticus but was probably a Hypsibius spp. Therefore, the actual presence of Acutuncus antarcticus in Africa needs to be confirmed.
