Poreuomena huxleyi Massa, 2013. J. Orth. Res. 22: 140; type locality: Equatorial Guinea, Fernando Poo, Santa Isabel ( MNCN).

Material examined.

Equatorial Guinea, Bioko (Fernando Poo), Santa Isabel (♂ holotype) (MCNM) ; Cameroon, Gulf of Guinea Is , Bioko ( Fernando Poo), Santa Isabel (Malabo) (1♂) ( NHMW) .

Diagnosis.

This species is easy to recognise by the short apical lobes on the 10th tergite of the male and cerci clearly upcurved and with a lateral spine. The most closely-related species is P. africana , which, however, has much longer lobes of the 10th abdominal tergite and more robust cerci.

Description.

Typical Poreuomena species with narrow tegmina surpassed by the alae by a few mm (Fig. 62 ). Stridulatory area marked brown (Fig. 64 ). Two spines are present on the ventral margin of the hind femora. The apical lobes of the 10th tergite are short and square, separated widely (Fig. 63 ); the cerci are in- and downcurved, dorso-ventrally flattened in the apical portion where a lateral spine is present.

Colour.

P. huxleyi is brownish coloured, with green tegmina and hind tibiae; a black marking is typical at the base of the tegmina and some small black spots on the posterior margin of the tegmina.

Distribution.

Equatorial Guinea and Cameroon.
