Treatment

Macrocheilus dorsiger (Chaudoir, 1876) View in CoL

Figs. 5f View FIGURE 5 , 6c View FIGURE 6

Studied material. 1 male: “ Burkina Faso: Nahouri \ Forêt de Nazinga, Akwazena \ 275 m, 11º 09′ 24″ N 001º 36′ 44″ O \ 21.VII.2006, zone Soudanienne\ savane boisée, piège lumineux\ F & S. Génien, 2006-53” \\ “Macr-08” (yellow label)\\ “ Macrocheilus \ dorsiger \ (Chaudoir, 1876)” [h]\ A.Serrano det. GoogleMaps 2021”[t] [h].

Remarks. The species has a scattered sub-Saharan distribution throughout northern and Central Africa ( Basilewsky 1962; Serrano 2000). It is recorded for Burkina Faso for the first time.

Male genitalia. Description and drawings of median lobe in lateral and dorsal views and left paramere were provided by Serrano (2000, Figs. 3 View FIGURE 3 , 4 View FIGURE 4 ). However, after re-examination of the median lobe of the Guinea-Bissau male specimen which was the support for the description of this structure for the first time ( Serrano 2000) and following the study of a male specimen from Burkina Faso, we concluded that instead of two pairs of sclerotized stripes on dorsum there is only one pair close to the margins.

Distribution. Burkina Faso, Democratic Republic of the Congo, Eritrea, Ethiopia, Guinea-Bissau, Republic of Ivory Coast.
