Remarks. The species was described originally from Angola ( Harold 1878). The adults, like happens with other species of Oplostomus , are associated with bees, preying on broods (e.g. Oldroyd & Allsopp 2017). This behaviour is confirmed by the notes associated with the IICT adult specimens, refering that all were captured in beehives (see also Gomes Alves 1973, pp. 48–49). It is a new species record for the Benguela Province.
