Leiodontocercus angustipennis Chopard, 1954 ( Figs. 40 a-b)

Material examined. Côte d’Ivoire, Taï National Park, Res. Station (174m) ( MV Light Trap) 25.III-17.IV.2017, A. Aristophanous, M. Aristophanous, M. Geiser, P. Moretto (1♂, 2♀) ; Liberia, Sinoe County, 6.5 km NW Jacksonville, Forest near Solve Problem Vill. (103m) 23-27.I.2018 ( MV Light Trap), M. Geiser, S. Safian, G. Simonics (1♀) ( ANHRT) .

Remarks. The genus Leiodontocercus has been revised recently by Massa (2020), who examined only the holotype; now another male was available and it was possible to examine the stridulatory file, consisting of ca. 60 teeth ( Fig. 40a ), similar to that of L. philipporum Massa, 2020 , but teeth are deeper; however, cerci of L. angustipennis are stout with an inner globose bulge ( Fig. 40b )

Distribution. It is known from Sierra Leone and Guinea (Massa 2020), newly recorded from Côte d’Ivoire and Liberia.
