Material examined.

Central African Republic, Dzanga-Ndoki National Park, Dieké 25.XI.2010, P. Annoyer (1♂, 1♀); Dzanga-Ndoki National Park, Lake 1, 31.I-2.II.2012 (1♀), 12-13.II.2012 (1♂), 13-14.II.2012 (3♂), 17.II.2012 (1♀); 20-23.II.2012 (1♀), 22-23.II.2012 (1♀); 28-29.II.2012 (1♂) (hand catching and light), SANGHA2012 Team; Lake 3, 25-26.II.2012 (light), P. Annoyer (1♀) (BMPC & PAPC); Central African Republic, La Maboké, M’Baiki II.1964, M. Pavan (1♂) (MSNP).

Remarks.

Leiodontocercus condylus has the central part of the stridulatory file with ca 50 thick teeth, that appear just deeper than in the other species (Fig. 6 ). The stridulatory area of the left tegmen is a little backwards protruding, more than in the other species (Fig. 13 ). This species is characterized by cerci stout with an apical swelling with the outer margin serrated and the inner part with two pointed black tipped teeth (Figs 15 , 16 ).

Distribution.

Leiodontocercus condylus has been described from Zaire (= Democratic Republic of Congo) and has been reported from Central African Republic (Dzanga-Ndoki National Park) by Massa et al. (2020); it is here recorded also from the M’Baiki forest in Central African Republic. Presently females are not recognized at species level and were identified as L. condylus because they were collected together with the males of this species.
