Etymology
In a checklist of Ocnodes Fåhraeus, 1870 by Kamiński et al. 2019,[1] the genus was treated as masculine, alongside the type species being subsequently designated as Ocnodes scrobicollis Fåhraeus, 1870. Per ICZN Article 30.1.4.4, a compound genus-group name ending in -odes is masculine unless its (original) author "stated that it had another gender or treated it as such by combining it with an adjectival species-group name in another gender form." Here, scrobicollis Fåhraeus, 1870 is a latinized epithet in common gender (masculine or feminine), but Fåhraeus, 1870 also originally included a second species, namely Ocnodes concinna Fåhraeus, 1870 with feminine inflection of its epithet. Therefore, the generic name Ocnodes Fåhraeus, 1870 is defensibly feminine rather than masculine. It is instead listed as feminine in a subsequent catalog of Tenebrionidae genera by Bouchard et al., 2021[2]
