Remarks. A widespread species in Africa south of Sahara ( Beinhundner 2017b; Schoolmeesters 2019). Taxonomical comments on this species were provided by Serrano et al. (2020). All the examined specimens exhibit two mesotibial teeth, pronotum with lateral punctuation and crenulation, which are considered diagnostic morphological characters of this species ( Basilewsky 1956; Rigout & Allard 1992). The larva (L 3) was described by Šípek (2005) and ecological data were provided by Holm & Marais (1992). The Buba Tombó adult specimen and the Susana adult specimens were sampled by CT and BT ( Figs. 2a, b ), respectively, in open forests, the former together with C. quadrisignata . The other adult specimens were captured flying in open forest. It is a new species record for CAC, BIB and QUN Administrative Regions of Guinea-Bissau.
