B905101F59C95BB59C96AF731CD39A78.taxon	diagnosis	Diagnosis. Sjoestedt (1912) stated that Griffini (1905 / 6) found no differences between C. tenuipes and C. mundamensis, both described by Karsch. Sjoestedt mentions that a generic character on which Cestromoecha was erected, is a missing mirror on the right tegmen, while C. mundamensis has a well-developed mirror. However, both C. tenuipes (Fig. 17) and C. mundamensis males have well-developed mirrors and a comparison of the outer genitalic system of both C. tenuipes (Figs 19 - 21) and C. mundamensis showed no differences. Therefore, we suggest to synonymize both species that also have an overlapping distribution pattern to be synonymised.	en	Hemp, Claudia, Massa, Bruno (2021): Biogeographical and evolutionary aspects of a Guineo-Congolian bushcricket tribe: Revision of the genera Cestromoecha Karsch, 1893 and Poreuomena Brunner von Wattenwyl, 1878, with the description of new species (Orthoptera, Tettigoniidae, Phaneropterinae).

034029867C9150E09DEB0B515F302F99.taxon	diagnosis	Diagnosis. Griffini (1908) supposed that, because Bolivar (1906) overlooked the paper of Sjoestedt (1902), P. gladiator Bolivar, 1906 from Cameroon could be synonymous with P. forcipata Sjoestedt, 1902, also from Cameroon. The male cerci of the two taxa are identical. Both lack the black marking on the stridulatory area of the male left tegmen (Fig. 54); thus P. gladiator has been synonymised with P. forcipata by Massa (2013). Morphologically most closely related to P. laeglae (both species share an asymmetrical supra-anal plate with a spine on the left margin, Fig. 55), P. tshuapa sp. nov. and P. magnicerca (also see diagnosis at P. laeglae).	en	Hemp, Claudia, Massa, Bruno (2021): Biogeographical and evolutionary aspects of a Guineo-Congolian bushcricket tribe: Revision of the genera Cestromoecha Karsch, 1893 and Poreuomena Brunner von Wattenwyl, 1878, with the description of new species (Orthoptera, Tettigoniidae, Phaneropterinae).

DF280AB773D85DD895CD10D62CDC73A3.taxon	diagnosis	Diagnosis. P. ivoriana sp. nov. is a comparatively small species of Poreuomena, characterised by its green colour, the blackish triangular areas on the left and right tegmina (Fig. 65) and incurved cerci with a flattened inner process (Figs 67, 68). Probably morphologically related to P. lamottei distributed further west in Africa. The male cerci of both species are differentiated into flattened structures in both species, however, more pronounced in P. ivoriana sp. nov. The 10 th abdominal tergite is very different in both species. While in males of P. lamottei, the posterior margin of the 10 th abdominal tergite forms two comparatively long and, at their tips, downcurved processes, in P. ivoriana sp. nov. only two short lobes are developed.	en	Hemp, Claudia, Massa, Bruno (2021): Biogeographical and evolutionary aspects of a Guineo-Congolian bushcricket tribe: Revision of the genera Cestromoecha Karsch, 1893 and Poreuomena Brunner von Wattenwyl, 1878, with the description of new species (Orthoptera, Tettigoniidae, Phaneropterinae).

03A9D8559A845A979BF219183E49B8D2.taxon	diagnosis	Diagnosis. P. laeglae was described in the genus Cestromoecha, but it actually belongs to the genus Poreuomena because it has two well-developed tegminal flaps and no mirror. The Rs vein branches off near the base and not past the middle as typical for Cestromoecha. It is morphologically most closely related to P. forcipata (both species share an asymmetrical supra-anal plate with a spine on the left side) and also to P. magnicerca and P. tshuapa sp. nov. The cerci of the males are differentiated into two branches in the first two species, with a finger-like apical or outer branch and a blade-like expanded inner branch, however, differently shaped between P. laeglae and P. forcipata. In P. magnicerca and P. tshuapa sp. nov., the third blade-like branch or expansion is present giving the expression of the cerci having three branches. The flaps on the left tegmina bearing the stridulatory files on the underside are differently shaped between P. tshuapa sp. nov. (oval and pointed) and P. magnicerca (laterally slightly expanded and not pointed) as is the shape of the stridulatory file itself supporting species status for P. tshuapa sp. nov. The 10 th abdominal tergites, however, are very similar amongst these four species since they are rather undifferentiated with a more or less straight posterior margin and thus very likely derived from the bilobed condition as the generic character of the genus Poreuomena. The stridulatory file of P. laeglae is similar to that of P. magnicerca with a distal part with less and more widely-spaced teeth than in the proximal part (Massa 2015).	en	Hemp, Claudia, Massa, Bruno (2021): Biogeographical and evolutionary aspects of a Guineo-Congolian bushcricket tribe: Revision of the genera Cestromoecha Karsch, 1893 and Poreuomena Brunner von Wattenwyl, 1878, with the description of new species (Orthoptera, Tettigoniidae, Phaneropterinae).

86E042B52E1B53F3A40D7320B7148660.taxon	diagnosis	Diagnosis. Similar in the outer male genitalic apparatus to P. magnicerca from further west in the Congo Basin. Differentiated from P. forcipata and P. laeglae by a different 10 th abdominal tergite which is clearly divided into two lobes in P. forcipata, while P. tshuapa sp. nov. only has small humps and the posterior margin of the 10 th abdominal tergite of P. laeglae is more-or-less straight. P. forcipata has male cerci differentiated into two branches, an outer rather blunt, finger-like part and an inner blade-like expanded branch with an acute tip, similar to the inner branch of P. tshuapa sp. nov. and P. magnicerca. However, P. tshuapa sp. nov. has an additional branch just below the finger-like part of the cerci, absent in P. forcipata, but also present in P. magnicerca (also see diagnosis at P. laeglae). In P. magnicerca, the blade-like subapical section or the " third " branch is more roundish and larger than in P. tshuapa sp. nov. and the subgenital plate differs between these two species. In P. tshuapa sp. nov., the subgenital plate is bilobate with the processes clearly separated, while in P. magnicerca, the lobes of the subgenital plate are shorter and situated more closely to each other. Further, in P. forcipata and P. laeglae, asymmetrical spines are present on the left side of the supra-anal plates.	en	Hemp, Claudia, Massa, Bruno (2021): Biogeographical and evolutionary aspects of a Guineo-Congolian bushcricket tribe: Revision of the genera Cestromoecha Karsch, 1893 and Poreuomena Brunner von Wattenwyl, 1878, with the description of new species (Orthoptera, Tettigoniidae, Phaneropterinae).

86E042B52E1B53F3A40D7320B7148660.taxon	description	Description. Male. Probably predominantly green when alive, preserved specimens of tawny colour (Fig. 97). Where tegmina meet when folded, interior part of cells of dark colour while surrounding and elevated veins green / tawny. Typical Poreuomena species with Rs branching off from the radius near the base. The tegmina have two typical well-developed flaps at their base, the flap on the left side smaller and more pointed than the flap on the right tegmen. Beneath the flaps, tegmina with narrow longish brown markings are typical for several Poreuomena species. The stridulatory file on the left tegminal flap is about 1.5 mm long with small broadly-spaced inner teeth becoming gradually larger and are more densely set (Fig. 98). The last third consists of very densely packed teeth becoming smaller again; the apical part is strongly curved. All-in-all, the stridulatory file consists of about 70 - 80 teeth. Stridulatory file on the underside of the right tegmen not as well-developed, but similar in shape and size and arrangement of the teeth. The 10 th abdominal tergite has almost a straight posterior margin with only two bump-like structures laterally (Fig. 99). The cerci are stout, divided at their apical part into three branches: a subapical blade located just beneath the second elongated, finger-like branch and an inner blade-like or leaf-like expanded branch with sclerotised margins (Figs 99, 100). The subgenital plate is elongated and deeply divided into two lobes; without styli (Fig. 100). Between the subgenital plate and the cerci, two longish internal structures are present (titillators).
