Remarks.

The genus Dapanera was erected by Karsch (1889) and is characterized by stout and long styli. Karsch (1889) described Dapanera genuteres , and later ( Karsch 1890) Dapanera irregularis , very similar to the previous species, but with different cerci shape and length of styli (shorter than in Dapanera genuteres ). Further, Griffini (1908), Sjostedt (1912) and Massa (2013) have highlighted that Dapanera irregularis is smaller than Dapanera genuteres and has shorter ovipositor. The genus Dapanera contains another species, Dapanera eidmanni (see below); all the species are morphologically very similar, with the exception of the shape of the male sub-genital plate, cerci, styli length and stridulatory files (Figs 31-49). The genus Gonatoxia was described by Karsch (1889) on the same page as Dapanera with the following differences: fastigium of vertex not sulcate, tegmina wider and genicular lobes of hind femora with a spine. However, the fastigium of Gonatoxia may be sulcate as shown in Fig. 48 and also the genicular lobes of the hind femora of Dapanera may present a small spine. Remaining as difference the width of tegmina, a variable character within the same genus in Phaneropterinae, it seems rather evident that Dapanera and Gonatoxia are synonyms, with priority for Dapanera , described by Karsch (1889) before Gonatoxia . Thus, the two Gonatoxia species become Dapanera maculata (Karsch, 1889), comb. n. and Dapanera immaculata (Karsch, 1889), comb. n. Species described in the genus Gonatoxia are known from East Africa, while those of the genus Dapanera from West and central Africa. A further new species of Dapanera is here described from the Central African Republic.
