However, we exclude this species from the diagnostic key, because its placement in the genus  Pentamerismus seems to be questionable. In contrast to all other species of the genus, it has only two pairs of pseudanal setae (ps), and setae f 2 occupy sublateral position. Meyer &amp; Van Dis (1993) highlighted that  P. collinus shares the presence of two pairs of pseudanal setae with the genus  Phytoptipalpus; however, as these authors attached greater taxonomic significance to the number of dorsosublateral setae, they considered setae f 2 to be in a lateral position and referred this species to  Pentamerismus .</p><p>It is crucial to understand which morphological character are persistent enough to be used for clear generic diagnoses of tenuipalpids. Both of the aforementioned characters (position of dorsal opisthosomal setae and number of pseudanal setae) have been used in combination to differentiate various tenuipalpid genera. The taxonomic significance of the number of pseudanal setae could not be denied at the generic level in the family  Tenuipalpidae, in particular, in the genera  Tenuipalpus,  Extenuipalpus,  Ultratenuipalpus, etc. (Mesa et al. 2009; Beard et al. 2016). We suggest that the presence of two pairs of ps setae should be confirmed by a careful re-examination of the type specimens of  P. collinus, and if this were the case, then it would be reasonable to place this species in the genus  Phytoptipalpus .</p></div>	https://treatment.plazi.org/id/FA5C8792FFAFFFF17285F594FEC14E64	Public Domain	No known copyright restrictions apply.

The Saudi specimen of  Pentamerismus (Oligomerismus) retusus morphologically resembles the original (Meyer 1979; South Africa) and supplementary descriptions (Meyer 1993; Namibia). The Saudi specimens were compared with the images of the holotype of  P. (O.) retusus . The dorsomedial striae on propodosoma are longitudinal and weak in Saudi specimens (female and male), while in compared specimens, striae form a circular pattern (Meyer 1979, holotype) or surface is rugose (Meyer 1993). The pattern of striation between setal rows C and D in our specimens is mostly transverse with a small region of arched striae compared to irregular to transverse striaein the holotype (Meyer 1979). The propodosomal setae of Saudi specimen (female and male) are subspatulate serrate in shape compared to broadly spatulate (Meyer 1979) and broadly lanceolate to subspatulate (Meyer 1993). The length of dorsal propodosomal setae v 2 is half the distance v 2 –v 2 compared to one third in the holotype (Meyer 1979, 1993).</p></div>	https://treatment.plazi.org/id/FA5C8792FFAFFFF87285F0C8FEAF48C1	Public Domain	No known copyright restrictions apply.
