Poreuomena lamottei Chopard, 1954. Mem. Inst. franc. Afr. Noire 40(2): 40; type locality: Guinea, Nimba, N’zo (MNHN).

Material examined.

Côte d’Ivoire, Azagny National Park (light trap) (3♂) ; Côte d’Ivoire, Tai National Park , Res. Station 5-10.VII.2015 (light trap) (1♂) (NHM) .

Diagnosis.

P. lamottei has a similar 10th abdominal tergite as P. eala sp. nov., but the lobes are much narrower and have a large gap between them in P. lamottei . In addition, the male cerci are similar between the two species, stout and upcurved at their tips, however, with bifid tips in P. eala sp. nov.

Description.

Typical Poreuomena species with stridulatory area marked dark brown (Fig. 75 ). The stridulatory file is arched and consists of about 60 teeth, of which roughly 30 large teeth are situated in the distal part and 30 smaller and evenly-spaced teeth in the proximal part (Fig. 76 ). The last tergite is differentiated into two stout and downcurved processes (Figs 77 , 78 ); the subgenital plate is elongated with two outcurved lobes (Fig. 79 ); the cerci are stout and incurved and possess an apical flat tip with three short processes (Fig. 78 ).

Distribution.

Guinea, Ghana ( Chopard 1954; Naskrecki 2009) and Ivory Coast ( Massa 2017).
