The helmet toktokkies (genus Ocnodes) are ground-dwelling, Afrotropical beetles in the family Tenebrionidae.
A selection of species include:
Note: Several species that were previously placed the former subgenus Ocnodes (Chiliarchum) (e.g. Kamià Âski et al., 2019), were later included in the valid genus Chiliarchum in Kamià Âski et al., 2020.
In a checklist of Ocnodes FÃÂ¥hraeus, 1870 by Kamià Âski et al. 2019, the genus was treated as masculine, alongside the type species being subsequently designated as Ocnodes scrobicollis FÃÂ¥hraeus, 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 FÃÂ¥hraeus, 1870 is a latinized epithet in common gender (masculine or feminine), but FÃÂ¥hraeus, 1870 also originally included a second species, namely Ocnodes concinna <small>FÃÂ¥hraeus, 1870</small> with feminine inflection of its epithet. Therefore, the generic name Ocnodes FÃÂ¥hraeus, 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
