Remarks. Olivinirmus borneensis Mey, 2017 has male genitalia that are unlike those of all other known species of Olivinirmus , but are typical of many species of Guimaraesiella . The illustration of the tergopleurites and the habitus photograph support the placement of this species in Guimaraesiella . However, the lack of illustrated details of the male genitalia ( Mey 2017: fig. 32, not 22 as stated in the description on page 108) make this placement somewhat tentative. Mey’s (2017: fig. 24) illustration of the lateral tergopleurites depicts an accessory postspiracular seta (aps) on segment V, which is standard in most species of Guimaraesiella (see Gustafsson & Bush 2017: table 10). This species needs to be thoroughly redescribed, so that its correct generic position can be established. We therefore tentatively place Ol. borneensis in Guimaraesiella new combination, making this taxon the first Guimaraesiella known to parasitize corvid hosts.
