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.
