Omorgus sp.

Omorgus sp. indet.

MEXICO: COAHUILA. Huchet et al. (2013) reported fragments of an unidentified Omorgus species recovered from pre-Columbian funeral bundle in the Candelaria Cave, a mortuary cave. In an archaeological context, the presence of the beetle fragments in the funeral bundle would imply a period during which the corpse was accessible to colonisation by insects, and hence unburied ( Huchet et al., 2013). These authors speculated that “[I] n all likelihood, the colonization took place during the dry decay stage, the insects attracted by desiccated skin and ligaments ” (p. 286). In line with our argumentation elsewhere in this paper, we consider this to be an accidenal visitor to a cave.

Trox sp (p). and/or Omorgus sp (p). indet. (reported as Trox spp. ).

AUSTRALIA: NORTHERN TERRITORY, QUEENSLAND, NEW SOUTH WALES. Numerous records of unidentified Trogidae exist in the literature: from various, but mostly unspecified, caves, including ‘guano caves’ and ‘bat caves’ ( Moulds, 2004), and from bat guano deposits in caves ( Hamilton-Smith, 1967). These species may include troglophiles and bat-guanophiles ( Moulds, 2004), but in the absence of species-level identifications, and in the absence of better field notes, these records are only an indication of a larger cavernicolous trogid fauna than what we list here.
