Chimetopon camerunensis Schmidt, 1910 from Equatorial Africa along with Oronoqua orellana Gnezdilov et Bartlett, 2020 and Sarnus rhomboidalis Fennah, 1965 from South America are included in the molecular analysis of the family Issidae for the first time. DNA of Ch. camerunensis was extracted from an old dry specimen collected more than 50 years ago. Based on our analysis, the tribe Chimetopini Gnezdilov, 2017 is nested within the subfamily Hysteropterinae, showing close relationships to North African and southern European genera Falcidius Stål, 1866 and Numidius Gnezdilov, Guglielmino et D'Urso, 2003. Additionally, we confirm the monophyly of the tribe Thioniini Melichar, 1906 and its position as a sister group to the tribe Issini Spinola, 1839 within the subfamily Issinae Spinola, 1839.
