Type locality. Togo (without additional data).

Type material examined. Xantholinus interocularis Eppelsheim, 1895 . It was not possible to find the type /s of Xantholinus interocularis , described from Togo. All reasonable steps were exhausted to trace the original type material of this taxon. Eppelsheim type specimens are housed in the NHMW. The curator of NHMW searched for type material, but without success. We can only conclude that the type material has been lost. To stabilise the systematic position of this species in this complex species group, we decided to designate a neotype. The specimen selected as the neotype matches the original description of Eppelsheim (1895) and falls within the area of original type locality ( Togo). Neotype (by present designation) ♂: TOGO: “ Togo ” ( DEI). The specimen is chosen as neotype. The labels “ Neotypus Xantholinus interocularis Epp., Bordoni des. 2014” and “ Thyreocephalus interocularis (Epp.) , Bordoni det. 2014” were attached to this specimen.

Thyreocephalus diversiceps Bernhauer, 1936 View in CoL . Lectotype (by present designation) ♀: DEMOCRATIC REPUBLIC OF CONGO: “Musée du Congo, Lulua: Kapanga”, “ III.1933, G. F. Overlaet”, “ Thyreocephalus diversiceps Brnh. View in CoL Typus.” (FMNH). The specimen is chosen as lectotype of the species. It is identical to T. interocularis View in CoL . The labels “ Lectotypus Thyreocephalus diversiceps Bh., Bordoni View in CoL des. 2011” and “ Thyreocephalus interocularis (Epp.) View in CoL , Bordoni det. 2012” were attached to the specimen.

Redescription. Body length 15–19 mm; length from anterior margin of head to posterior margin of elytra: 9– 11 mm. Black with bluish elytra and abdomen slightly reddish. Shiny. Head and pronotum with micro-punctation. Head and pronotum and related punctation as in Fig. 158 View FIGURES 158 – 165 ; labrum as in Fig. 159 View FIGURES 158 – 165 . Elytra longer and wider than pronotum, squared, slightly dilated posteriad, with rounded humeral angles. Surface with wide and superficial punctation, arranged in three series, one near suture, one median and one lateral. Abdomen with feeble or evident traces of transverse micro-striation, with fine and very spaced punctation, arranged in a few series.

Male. Tergite 10 and sternite 9 of male genital segment as in Figs. 160, 161 View FIGURES 158 – 165 . Aedeagus relatively small, 1.9–2.6 mm long, median lobe generally wide, sub-triangular ( Fig. 162 View FIGURES 158 – 165 ), rarely markedly narrower and variably shaped, but always apically pointed ( Figs. 163, 164 View FIGURES 158 – 165 ); parameres symmetrical ( Figs. 162, 165 View FIGURES 158 – 165 ); inner sac ribbon-like, wide and long, folded on itself, covered with little scales.

Differential diagnosis. Thyreocephalus interocularis differs from the similar T. basilewskyi in disc of head generally sparsely and finely punctured and in paramere of aedeagus relatively long. The punctation of the head in extreme specimens of both species is very similar.

Distribution. Distributed in West, Central and East Africa ( Fig. 147 View FIGURE 147 ).

Remarks. This species is variable in dimensions of the body and aedeagus, and in punctation as well. For example the specimens from Kivu have a larger aedeagus (about 2.6 mm long). The most constant character is the length of paramere in relation to the length of aedeagus.
