Remarks
- Systematics: This species is most similar to O. warniae by having narrow enlarged setae and by lacking dorsal multilocular pores. Octococcus pentziae differs by having (character states in brackets are those of O. warniae): few large-sized oral-rim tubular ducts, segment IV with two to five such ducts (many large-sized oral-rim tubular ducts, segment IV with 12–19 such ducts); large-sized oral-rim tubular ducts in incomplete transverse rows across abdominal segments (complete rows); with three to five suranal setae (seven to 12 setae). (Miller & Giliomee, 2016)
- Structure: From Hall (1939) ‘Adult female enclosed in a closely felted sac which is white or more often dirty white on account of extraneous matter which has become incorporated. The sac is broadly ovoid and convex, almost globular, with a small orifice towards one extremity. Dead adult females smoky black or very dark purple, shrivelled and very small-rarely exceeding 1 mm. in length. The dermis appears to be devoid of secretionary covering and no lateral or caudal filaments apparent. The adult female when mounted for microscopical examination is oval in outline, small and often shrivelled and rarely exceeds 1.5 mm in length and 1.0 mm. in breadth.'
- General Remarks: Description and illustration of the adult female given by Williams (1958b). Redescription and illustration of adult female in Miller & Giliomee, 2016.
