Taxonomic note. In 2009, I attempted to interpret the identity of Thinodromus nigerius Gildenkov, 2000 based on two male specimens from Côte d’Ivoire and Nigeria (see redescription in MAKRANCZY 2009: 53). Immediately after the publication of the paper, I received two more Thinodromus specimens from Nigeria, a male ( Figs 13, 15–16 View Figs 13–18. 13–16 ) and a female ( Fig. 14 View Figs 13–18. 13–16 , without elytra). These specimens doubtlessly belong to the same taxon that I discussed as T. nigerius . The study of the previously unavailable female ringstructure ( Fig. 83 View Figs 81–85. 81–83 ), i.e. the only diagnostic female genitalic feature in this group of species, revealed that it is closely similar to that of T. kedougouensis Makranczy, 2009 described from Senegal. Therefore, it seems that we are dealing with a single externally variable species and the known specimens are just parts of its morphological continuum. Specimens previously mentioned by me as T. nigerius (see Figs 19, 20, 21 View Figs 19–27. 19 , 31, 32 View Figs 28–33. 28–31 , 68 View Figs 64–69. 64–66 in MAKRANCZY (2009) for terminalia and genitalia) and T. kedougouensis ( Figs 47, 48, 49 View Figs 46–51. 46–47 , 55, 56 View Figs 52–57. 52–54 in MAKRANCZY (2009), and Figs 75–76 View Figs 70–76. 70–74 and 83 View Figs 81–85. 81–83 here) seem therefore to be conspecific. This is also supported by the examined specimens from Bénin (all from the same collecting event and likely from the same microhabitat) which contain two conspecific males (based on morphology of the genitalia), with entirely different antennae: one has shorter antenna much similar to that illustrated in the original description of T. nigerius , the other has much more elongate antenna, as that in Fig. 15 View Figs 13–18. 13–16 in this study.

For the reasons given above, T. kedougouensis Makranczy, 2009 is here conditionally synonymized with T. nigerius Gildenkov, 2000 . The synonymy needs to be confirmed by more material from the type locality of T. nigerius .
