Acleros (Isocleros) instabilis Mabille, 1889 and Acleros (Isocleros) olaus (Plötz, 1884) are species distinct from Acleros (Isocleros) mackenii (Trimen, 1868)

Inspection of genomic trees ( Figs. 45, 46) and analysis of genetic differentiation reveals that Acleros instabilis Mabille, 1889 (type locality in Tanzania) and Apaustus olaus Plötz, 1884 (type locality in Congo, syntype sequenced as NVG-18073C07) currently treated as subspecies of Acleros (Isocleros) mackenii (Trimen, 1868) , (type locality in South Africa, possible syntype sequenced as NVG-20126G11) (17 bp), respectively, and from each other with 0.39/4.7% (31 bp). Therefore, we propose to reinstate these two taxa as species: Acleros (Isocleros) instabilis Mabille, 1889 , stat. rest. and Acleros (Isocleros) olaus (Plötz, 1884) , stat. rest.
