Tribe
Dysoniini
Rehn, 1950
Diagnosis.
Small to medium-sized (
25–65 mm
). Eyes globose, distance of the antennal sockets not greater than the width of the scapus. Vertex elevated in diverse shapes, from a slightly raised tubercle or crest to long spines. Fastigium with a developed ventral tooth, ocellar tubercle present and only slightly or well developed. Pronotal disc also with various modifications (like spines, expansions, denticulations). Tegmina narrow or moderately widened, Rs vein originating at the middle of R, MA vein prolonged to the middle of the tegmina and then turning into the anal margin. Anterior coxae dorsally armed with a fronto-basal spine; tympana exposed on both sides of the fore tibiae; leg spines lamellate, developed as spinule or long, pointed spines. Genicular lobes of fore and middle femora are usually armed with a spine (in
Quiva
armed with two small spines). Meso- and metasternum never longer than wide, meso- and metafurcal furrow narrow and usually rounded. Tenth tergite unmodified; male cerci forked, usually divided in the horizontal plane (except
Apolinaria
, where the both branches are directed dorsally); male subgenital plate unmodified (except for
Lichenomorphus
, where it is elongated and very flexible), and styli developed to different degrees. Ovipositor of females varying in shape, from as long as the pronotum, curved and broadened, to long and slender, surpassing the length of the pronotum.

Comments:
Recently,
Gorochov (2014
,
2016
) considered
Trachyzulpha
Dohrn, 1892
, a genus from Southeast Asia, to be a member of
Dysoniini
, placing it in its own subtribe
Trachyzulphina
. The supposed justification being the shared lichen mimicry. However, this
type
of mimicry has arisen several times in the subfamily
Phaneropterinae
, and also in other katydids like
Lichenagraecia
Rentz, Su & Ueshima, 2012
from
Australia
(
Conocephalinae
:
Armadillagraeciini
) as well as several groups of the family
Pseudophyllinae
, and even in Caelifera such as pygmy grasshoppers of the genera
Amorphopus
Serville, 1838
and
Eomorphopus
Hancock, 1907
from the Amazon (
Cadena-Castañeda
et al
. 2019a
,
2019b
). An adaptation to a particular
type
of environment or microhabitat is not necessarily associated with a particular taxonomic group. Therefore, the Trachyzulphini
n. stat.
are here elevated to a separate tribe of the
Phaneropterinae
, based on the original diagnosis (
Gorochov 2014
).

Dysoniini
.
Moreover,
Gorochov (2016)
proposed to reduce
Pycnopalpini
to a subtribe of
Dysoniini
, arguing that the posteromedial denticle or spine on the upper rostral tubercle is also present in some representatives of that group. However,
Pycnopalpini
+
Dysoniini
do not belong to a monophyletic group according to the most comprehensive phylogeny of
Tettigoniidae (
Mugleston
et al
. 2018
)
. The
Pycnopalpini
are considered a tribe with two subtribes, Pycopalpina and Theiina (
Cadena-Castañeda 2014a
, Cigliano
et al.
2022).
