Based on the current description of the tribe Amblycoryphini some related genera have been excluded. These genera comprise two new tribes (Vossiini n. trib. and Plangiopsiini n. trib.) and a new generic group (Plangiae n. group). The main
differences between the taxa described and the tribe Amblycoryphini are discussed, to understand the new proposed classification. Plangiopsis aedeps is placed in the genus Plangiola. This paper contributes to the knowledge of the tettigonid
fauna from Africa and understanding of the taxonomy of neotropical Phaneropterinae.
Key words: Amblycoryphini, Vossiini n. trib., Plangiopsiini n. trib. Plangiae n. group, Africa, Neotropics
En base a la descripción actual de la tribu Amblycoryphini, se excluyeron algunos géneros relacionados en el pasado con
la misma. Dichos géneros componen dos nuevas tribus (Vossiini n. trib. y Plangiopsiini n. trib.) y un nuevo grupo genérico
(Plangiae n. group). Se discuten las principales diferencias entre los taxones descritos y la tribu Amblycoryphini, para de
este modo entender la nueva clasificación propuesta. Se transfiere a Plangiopsis aedeps al género Plangiola. Con este
artículo se aporta al conocimiento de la fauna de tetigonidos de África y al entendimiento de la taxonomía de los Phaneropterinae neotrópicales.

The subfamily Phaneropterinae is one of the Tettigonioidea groups with higher taxonomic problems, particularly as
it relates to the classification at the suprageneric level. The subfamily consists of 344 genera (Eades et al, 2014).
147 genera are classified into 20 tribes (number of genera in brackets): Amblycoryphini (7), Acrometopini (7)
Arantiini (1) Barbitistini (15), Ducetiini (11), Dysoniini (13), Elimaeini (4), Holochlorini (27), Insarini (4),
Microcentrini (11), Mirolliini (5), Odonturini (13), Otiaphysini (2), Pardalotini (2), Phaneropterini (8),
Phlaurocentrini (3), Poreuomenini (5), Pycnopalpini (8), Steirodontini (3), Trigonocoryphini (3), Tylopsidini (1),
Viadanini (12). Among the remaining 212 genera, 107 are subordinate in 25 generic groups and 105 still remain
ungrouped. With the review and establishment of the tribe Amblycoryphini (Brunner von Wattenwyl, 1878,
Cadena-Castañeda, 2014), it was found that some taxa related to the tribe by authors like Brunner von Wattenwyl
(1878, 1891), Karsch (1890a, 1890b), Bolívar (1906) and Ragge (1968 and 1980) actually correspond to other
supra-generic taxa. The groups here have mainly an Afrotropical distribution.
The first supra-generic taxon is Vossiini n. trib., composed by the genera Azamia Bolivar, 1906, Vossia Brunner
von Wattenwyl, 1878 (Vossiina n. subtr.), Xantia Brunner von Wattenwyl, 1878 and Paraxantia Liu & Kang, 2009
(Xantiina n. subtr.). The second taxon derivative is Plangiopsiini n. trib. in which Plangiopsis Karsch 1889 and
Plangiola Bolivar, 1906 are included. Finally the group Plangiae n. group., is proposed temporarily while
searching a specific association with other taxa already described.

The tribe Plangiopsiini and Vossiini are created to host some genera that have obvious morphological characters
that do not fit with the current description of the tribe Amblycoryphini. The main characters that differentiate them
are the shape of the eyes, pronotum, tympana and terminalia (see table 1).

The eyes of Amblycoryphini and Vossiini are oval and elongate (fig. 3, 4, 7, 8), possibly due to convergence
between the members of both tribes. Plangiopsiini and Plangiae have evident differences, in which eyes are
subcircular or globose (fig. 5, 6). The pronotum of Vossiini is rounded and the posterior margin of the lateral lobe is
more developed than the anterior margin. The pronotal disc in the others tribes are flat and lateral lobe is rounded.
Perhaps the most outstanding character differentiating these supra-generic taxa are the tympana on the fore
tibiae, in Vossiini are partially concealed (covered by a shell or conch in both sides), Plangiae and Amblycoryphini
have both sides exposed. Plangiopsiini have asymmetric tympana, character that grouped with Holoclorini, but
asymmetric tympani may be a plesiomorphic character (Gorochov & Kang, 2002, Liu, 2011), possibly evidence of
a lineage within the subfamily consisting in several tribes; furthermore, the organization of the tribe Holoclorini
needs to be revised, just as the grouping and relationship with the Psyrae group.
