Plastocorypha ituriana  Bolivar, 1922

Plastocorypha cabrai Griffini, 1909  stat. rev.

[A] CH 4986, CH 4997 2 ♂

For the identification of Plastocorypha  species (five species in OSF) not many characters are available. Our males have a dark orange red face ( Fig. 13View FIGURE 13 J). Applying this character, the two Plastocorypha  forms with black faces ( nigrifrons  nigrifrons  and vandikana) can be excluded. In these two forms, the tip of the fastigium is tapering, while it is blunt in P. brevipes  (see OSF) and our animals. The remaining three forms have all dark orange red (“ferruginous”) faces and are all distributed in Central Africa— brevipes Rehn, 1914  , nigrifrons cabrai Griffini 1909  and ituriana  Bolivar 1922. P. brevipes  has shorter hind femora than the other two and our specimens. Bolivar did not give any diagnosis when describing ituriana  , only “voisine de vandikana” (=related to vandikana). Although caprai (we propose to treat it as species due to the difference in colour of the face) and ituriana  may be the same taxon, we will call our animals at the moment P. ituriana  , since the type locality of cabrai (Mayumbe)  is near the Atlantic Ocean.

Song. The calling song ( Fig. 17View FIGURE 17) consisted of long echemes (ca. 4 s) with a syllable repetition rate of ca. 40 Hz (T= 21 ºC). In our nightly field recording, two males were imperfectly synchronizing, at the beginning or the end of the echeme the softer singing male could be heard (in Fig. 16View FIGURE 16 at the end). The echemes were separated by intervals of ca. 25 s.

The stridulatory file ( Fig. 16View FIGURE 16 C) is similar to that figured in OSF for P. brevipes  . In both species there is a small bulge near the proximal end.
