INTRODUCTION
Tetrigidae of Ecuador are only partially known, mostly on the basis
of the two main contributions on Orthopteroid fauna of Ecuador (GI-
GLIO TOS 1898, HEBARD 1924b). Other useful references are GÜNTHER
(1939) and the contributions by Lawrence Bruner. To date a work com-
Atti Acc. Rov. Agiati, a. 257, 2007, ser. VIII, vol. VII, B42
prehensive of all the species and identification key on Ecuador is lacking,
so the present paper wonts to be a first step to such a goal.
Working on Neotropical tetrigids is particularly difficult due to the
scarcity of material in Museums and private collections. This appears
rather strange, being Tetrigidae a group of insects so common along
water streams and ponds, especially in Neotropics. Further difficulty
in approaching this group is represented by the literature, mostly scat-
tered, not revisional and limited to small groups of species, and espe-
cially not using a modern systematics approach. GÜNTHER (1939) pro-
vided an identification key for subfamily Metrodorinae, to which be-
long most of the South American species, but he examined only a frac-
tion of the types so that probably misinterpretation of some descrip-
tions was unavoidable. Subfamily Batrachideinae is revised by GRANT
(1955, 1956), except for the very large genus Tettigidea, for which the
revision was never published. Subfamily Cladonotinae is also revised
by GÜNTHER (1938), while Tetriginae were never been reviewed, the
most recent work by STEINMANN (1969) listing 20 species.
Resulting from this situation is that a revision of all Neotropical
genera of Tetrigidae is strongly needed.
The present work results from recent collecting expeditions since
2002 run by the first author. Identification of the species was made by
the second author. Furthermore the collection in Museo Regionale di
Scienze Naturali di Torino has been examined.
The material examined is now in the private collection of the first
author in Arzignano, Italy, abbreviated as F.M.B., and in the Institute
Royal des Sciences Naturelles de Belgique, Brussels, Belgium, abbre-
viated in ISNB.
Species collected during expeditions in Ecuador since 2002 are li-
sted, the synonymy comprehensive of all citations concerning Ecuador
is listed for each species plus the material examined and some notes.

The genus Batrachidea Serville includes five species all from South
America and was revised by GRANT (1956).
B. inermis Hebard was known for Colombia only and the speci-
mens here reported are the first record of the species for Ecuador whe-
re it is present in the Coastal Plains.
All the material examined is brachypronotal.

B. mucronata (Saint-Fargeau & Serville, 1825) Fig. 1, is widely di-
stributed in South America, being present in Colombia, Ecuador, Peru,
Bolivia and Brazil (GRANT 1956). The distribution of the species in Ecua-
dor covers Amazonian part, Andes and Coastal Plains.
This species differs only slightly from B. macella Grant 1956, so
that is not clear if these are separate species.
Atti Acc. Rov. Agiati, a. 257, 2007, ser. VIII, vol. VII, B44
GRANT (1956) synonymized B. notata Bruner 1906 and Tettigidea
gracilicornis Bruner 1910 with B. mucronata.
The brachypronotal specimens collected are much bigger than
macropronotal specimens, a character typical of Batrachideinae.

The small Central and South American genus Paurotarsus Hancock
includes two species: P. insolitus Rehn 1916, divided in three subspe-
cies, and P. ruficornis (Walker 1871).
Hebard (1924a) synonymized P. amazonus Hancock 1900 and P.
rugosus Bruner 1906 with P. ruficornis.
P. ruficornis is distributed in Bolivia, Brazil, Peru, Trinidad (GRANT
1955) and Amazonian Ecuador.

The genus Scaria Bolivar 1887 has not been revised since 1910 and
therefore is in need of revision. Eight species have been described with
range from Southern United States to South America.

The single macropronotal male collected is the first record for Ecua-
dor of this species that was known for Peru, Bolivia and Brazil. In Ecua-
dor the distribution of S. producta Hancok is Amazonian.

Within the genus Allotettix Hancock 1899, eight species are actual-
ly included, all from South America except for A. peruvianus Bolivar
1887 and A. cayennensis Bolivar 1887 which are present also in Costa
Rica and West Indies respectively. The first species is cited with some
doubts sub Paratettix peruvianus by GIGLIO TOS (1898) on the basis of
a single specimen collected in the valley of Santiago River in Ecuador.
More later HEBARD (1924b) ascribes to A. peruvianus a single female
from «Allpa-yacu, Rio Pastaza, Tunguragua, 3600 feet (ca 1080 me-
ters)» probably on the eastern slopes of the Andes.
Type locality of the A. americanus is Cachabi. In Ecuador the spe-
cies ranges from the western slopes of the Andes to the coastal plains.

The Central and South American genus Chiriquia Morse 1900 is
very easy to recognise among Metrodorinae, by the peculiar position of
the antennae that are placed very below the base of eyes.
Four of the six described species are from Ecuador: C. compressa
Günther 1939 with type locality Ecuador, Rosario, C. mirifica Hebard
47F. M. BUZZETTI & H. DEVRIESE: Tetrigidae from Ecuador...
1924 with type locality Ecuador, Rio Pescado, Azuay, 480 m., C. spina-
ta Günther 1939 with unspecified Ecuadorean type locality and C. con-
cinna (Bolivar). C. concinna is known in Ecuador for the Coastal plains
and for the Western slopes of the Andes.

The genus Crimisus Bolivar 1887 has the lateral lobes of pronotum
only slightly produced, so that it could be also attributed to subfamily
Tetriginae which has the lateral lobes of pronotum not produced. This
feature is shown clearly by the present species having the lateral lobes
of pronotum not extended from the body.
This species was known before only for Bolivia and this is the first
record for Ecuador.

Twelve species have been described in the genus Crimisus Bolivar
1887 and in Sclerotettix Bruner 1910, the latter synonymized by GÜN-
THER (1939) with Crimisus.
These specimens from Ecuador have very enlarged middle femora,
this a typical character of C. tibialis. Nevertheless the present species
resembles two species very related to it: C. steinbachi (Bruner 1913)
and C. variegatus (Bruner 1910). The first differs from tibialis in having
the middle femora slightly less expanded, the latter for the comparati-
vely smoother pronotum and legs.

Known before only for Brazil, the species is likely present all along
the Amazonian Basin.

The South American genus Eomorphopus Hancock 1900 includes
3 species and can be distinguished from the related genus Amorphopus
Serville 1838 by the not dilated forelegs.
E. antennatus (Fig. 2) was known before for Brazil, Trinidad (BRU-

The five species contained in the genus Scabrotettix Hancock 1907
are all from South America, three of them known for Ecuador: S. ama-
zonus Bolivar 1887, S. scabrosus Hancock 1907 and the species here
reported. The species of this genus are not very well distinguished.
S. bolivianus is a very variable species with two macropronotal for-
ms: one with pronotum extending behind the hind femora, the other
with pronotum as long as the femora. Even the extension of the wings
beyond the pronotal hind tip, this character separating the two subspe-
cies of bolivianus, is very variable within the same populations of the
two subspecies.

OTHER SPECIES CITED FOR ECUADOR:
Among Batrachideinae:
Scaria brevis Hancock 1909 described from unspecified locality in
Ecuador.
Scaria fasciata Hancock 1907 described from Cachabi, in Ecuado-
rean Coastal Plains (HEBARD 1923).
Scaria hamata (De Geer 1773) is cited by GIGLIO TOS (1898) from
Valley of Santiago River.
Scaria maculata Giglio Tos 1898 described on one male and one
female from Ecuador, Valley of Santiago River. The species does not
appears on Orthoptera Species File online version june 2007, but was
not synonymized with other species. No material bearing this name is
present in the material studied by Giglio Tos in the Museum of Torino.
Rehnidium perexiguum Grant 1956 described from Baños in the
Ecuadorean Andes.
Tettigidea planus Hancock 1907 described from Paramba, on Ecua-
dorean Andes (BRUNER 1910).
Among Metrodorinae:
Amorphopus notabilis Serville 1838 cited sub Paratettix cnemidotus
by GIGLIO TOS (1898) on the basis of a single female from Cuchipamba
at about 1050 meters of elevation on the eastern slopes of the Andes,
northwest of Gualaquiza. This specimen was collected by Enrico Festa
during one of his two visits to the hacienda Cuchipamba, the first the
12 November 1895, the latter the 18-20 July 1896. The travel report of
the Italian naturalist (FESTA 1909) gives no informations on collecting
of Orthoptera in Cuchipamba, but since the second visit was characte-
rized by continuous rains that compelled Festa to stop there inside the
hacienda for two days, the specimen of A. notabilis was likely collected
during November 1895. The specimen from Coca examined by GÜN-
THER (1939) is the largest of the series reported. The species is known
in Ecuador East of the Andes.
The genus Cotys Bolivar 1887 contains two species, both known
for Ecuador. Cotys gibbulosus Hancock 1913 described from Santo
Domingo del Los Colorados and C. antennatus Bolivar 1887 cited by
GÜNTHER (1939) for Amazonian Ecuador.
Otumba amazonica (Bolivar 1887) reported by GIGLIO TOS (1898)
sub Metrodora amazonica from Valley of Santiago River.
Otumba incompta Hebard 1924. As noted by HEBARD (1924b) the
genera Otumba Morse 1900 and Cotys Bolivar are very near and some
51F. M. BUZZETTI & H. DEVRIESE: Tetrigidae from Ecuador...
species bear character states intermediate between the two genera, so
that are not clearly ascribable to one or the other genus. Type locality
of the species in exam is Rio Pescado, about 480 m, Azuay, apparently
ranging in Ecuador from the Andes to Coastal Plains. GÜNTHER (1939)
cites material of this species from Balzapamba on the Andes.
Chiriquia mirifica Hebard 1924. Described from Rio Pescado, about
480 m, Azuay, this species bears a peculiar characteristic among other
Neotropical tetrigids in having the carinae of the vertex dorsally pro-
duced in two small horns (HEBARD 1924b). Cited but not examined by
GÜNTHER (1939).
Scabrotettix scabrosus Hancock 1907 cited by HEBARD (1924b) refer-
ring to this species the single male from «between Quito and Napo Ri-
ver» mentioned by SCUDDER (1869) as Amorphopa caiman Saussure 1861.
Crimisus contractus Bolivar 1887 cited by GIGLIO TOS (1898) for
Pun and Huaca collected on 9-11 January 1897 according to travel notes
(FESTA 1909).
Trigonofemora fossulatus Hancock 1907, described from Peru, re-
ported by GÜNTHER (1939) for Ecuador, Santa Inez.
Plesiotettix Hancock 1907 comprehends P. spinosus Hancock 1907
and P. uncinatus Hancock 1907, both from Peru. GÜNTHER (1939) cites
one single male from Ecuador, Cachabé as Plesiotettix sp.
Crimisus acutus Günther 1939 described from Ecuador, Huaca.
Among Tetriginae:
Paratettix toltecus (Saussure 1861) reported by GIGLIO TOS (1898)
for Gualaquiza. HEBARD 1933 synonymized P. borellii Giglio Tos 1897
with P. frey-gessneri Bolivar 1887. The citation by Hebard appers ra-
ther criptic since he treats P. borellii as «Ecuadorean», actually being
that species described from Argentina; furthermore the author writes
as he had previously synonymized borelli with P. toltecus (Saussure
1861), but no reference is given and we found no synonymy of borelli
with toltecus in previous publications by Hebard.
DISCUSSION
In the Orthoptera collection of Museo Regionale di Scienze Natu-
rali di Torino, where the material collected by Enrico Festa and stu-
died by Giglio Tos should be preserved, the only tetrigids present are
Otumba amazonica (Bolivar 1887), identified by Giglio Tos as Metrodo-
ra amazonica, and Metrodora rana Bolivar 1887. Likely other material

has been sent to foreign specialists during the first decades of XXth
century and never returned.
After recent collectings and from literature, thirty-six specific and
subspecific taxa of Tetrigidae are known from Ecuador (Tab. 1), twen-
ty-nine were known previously to this study, the presence of five of
these is confirmed, seven are here reported for the first time. All are
from continental Ecuador since Galapagos Islands, one of World bio-
diversity hotspots, are apparently lacking of tetrigids as reported by
PECK (2001) and confirmed by recent expeditions on some islands of
the archipelago (Carotti, pers. comm.). This number is probably only a
part of the real Tetrigidae fauna of Ecuador, being this family overloo-
ked since many decades, at least in the Neotropics.

... The tribe Amorphopini Günther, 1939 [sensu Cadena-Castañeda andCardona-Granda (2015)] is exclusive to the New World and includes three genera: Amorphopus Serville, 1838 andEomorphopus Hancock, 1907 from the northern region of South America (Cigliano et al. 2019), and Platythorus Morse, 1900 from Central America (Bruner et al. 1900-1909, Cigliano et al. 2019). Among the Amorphopini, Amorphopus is morphologically similar to Eomorphopus but can be easily distinguished by the enlarged fore and mid-legs (Buzzetti andDevriese 2007, Cadena-Castañeda andCardona-Granda 2015). ...

The tribe Amorphopini Günther, 1939 is reviewed. It consists of two genera: Amorphopus Seville, 1838 and Eomorphopus Hankock, 1907 with three Neotropical species: Amorphopus notabilis Serville, 1838, Eomorphopus anten-natus (Bolívar, 1887), and Eomorphopus granulatus Hancock, 1907. Two species are transferred from Amorphopus to the genera Metrodora Bolívar, 1887 and Crimisus Bolívar, 1887, and two new combinations are proposed: Me-trodora gibbosula (Walker, 1871), comb. nov. and Crimisus humeralis (Walker, 1871), comb. nov. New synonyms are proposed: Amorphopus notabilis Ser-ville, 1838 = Amorphopus griseus Bolívar, 1887, syn. nov.; Metrodora gibbo-sula (Walker, 1871) = Platytettix reticulatus Hancock, 1906, syn. nov.; and Crimisus humeralis (Walker, 1871) = Allotettix bolivianus Brunner, 1913, syn. nov. Neotypes of Amorphopus notabilis and Eomorphopus antennatus as well as the lectotype of E. granulatus are designated. The description of Amorphopus testudo Saussure, 1861 is based on an immature specimen and we considered it as nomen dubius and the type depository of Eomorphopus purpurascens is unknown so we considered it, too, as nomen dubius. The tribe Amorphopini and all included taxa were redescribed and illustrated. A key to the genera and species is provided. Data on distribution, behavior, camouflage with lichens, polychromy, as well as ecological aspects of the species are reported.
... These nomenclatural acts are performed upon reviewing the type specimens and additional ones collected, observed and photographed in the field (Cardona, 2012, pags. 114, 115 determined as Scaria sp.) and the collection of Filippo Maria Buzzetti as quoted by Buzzetti & Devriese (2007). Species included: Only Scaria laeta Günther, 1940 stat. ...

The Amazon rainforest is the world’s most extensive tropical rainforest, holding a considerable ecological and taxonomic diversity. Speciation in this region arises from multiple factors, such as topography, climate fluctuations, oceanic transgression, vegetation and the delimitation of zones circumscribed by sub-basins within the greater Amazon basin. Different scenarios have been proposed to better understand the diversification of Amazonian taxa, whether by Pleistocene refugia or by areas of endemism. The genus Scaria is distributed mostly in Amazonia, with a single species that ranges from the Tumbes-Chocó-Magdalena ecoregion well into Central America all the way to southern Nicaragua. Eight species are currently recognized, with three additional described here as new: Scaria rafaeli sp. nov., S. jonasi sp. nov. and S. granti sp. nov., and the status of S. laeta stat. resurr. is revalidated. Two new combinations are established: S. verutum comb. nov. (formerly placed in Rehnidium Grant, 1956) and Batrachidea brevis comb. nov. (formerly placed in Scaria). New synonym is proposed: Batrachidea brevis (Hancock, 1909) = Batrachidea inermis Hebard, 1923 syn. nov. Lectotypes and paralectotypes were selected for S. laeta, S. maculata and S. lineata, as well as the neotypes for S. hamata and S. boliviana. An updated key to species of Scaria is also provided. A cladistic analysis for 15 species was performed (12 in the inner group and 3 in the outer group) with 40 morphological characters, confirming the monophyly of Scaria. A biogeographical analysis of dispersion-vicariance indicates that the origin of the genus was probably in the Inambari endemism center as the only reconstruction of the resulting ancestral distribution, five dispersions and three vicariance events being postulated. These suggest that both types of events are equally important in the current configuration of the distribution in Scaria. Vicariance events arise mostly by isolation of the species because of the uplift of the Andes and the dispersion events comprise four waves originating from the ancestral range into central and east Amazonia.

Tetrigidae Rambur, 1838 of Central America are severely understudied. Most of the historical data are restricted to the original descriptions of the species and scant records reported by the early tetrigidologists. This study examines the literature alongside the data made available through the efforts of citizen scientists. This allowed to compose a preliminary checklist of Central American Tetrigidae, which now numbers 32 species, and pair it with a key to the species. Northern countries of Central America remain nearly unexplored, which, together with certain taxonomic uncertainties within the known species, means that this checklist is merely the first step in researching this charismatic family of insects in the region.

Une clé d’identification des espèces est proposée. ABSTRACT Contribution to the knowledge of the Tetrigidae (Orthoptera) of French Guiana. This article provides a first assessment on the knowledge of the Tetrigidae Rambur, 1838 of French Guiana. It compiles the most relevant bibliographic data, published between 1861 and 2021, as well as data from field surveys carried out during the summer of 2019. The analysis inventories a total of 14 taxa including one species new for this area and one species new to science described in that article, Tettigidea claudei n. sp. An identification key to species is proposed.

Characters used to diagnose the subfamily Metrodorinae (Bolívar, 1887) (Orthoptera: Tetrigidae) are largely variable or homoplastic. Relevant traits used to distinguish amongst subfamilies of Tetrigidae, including sensorial structures, mouth parts, and genitalia are not present in any description of representatives of the subfamily Metrodorinae. The identity of Metrodorinae remains thus at stake. Aiming to fill the current lack of knowledge, a complete anatomical description of adult and last instar nymphs of Allotettix simoni (Bolívar, 1890) is provided. Allotettix simoni is a controverted taxon, originally described in the genus Paratettix and subsequently synonymized with Allotettix peruvianus. The revision of type specimens revealed that A. simoni and A. peruvianus are different species. As neither keys nor descriptions of nymphs of Neotropical Tetrigidae exist, A. simoni nymphs were identified comparing mitochondrial sequences of the cytochrome c oxidase subunit I (COI) gene with adult specimens. The anatomical description of A. simoni expanded by comparisons with material of Metrodora sp. nov., revealed that the subfamilies Metrodorinae and Tetriginae are morphologically very similar, whereas molecular analyses of the COI data set do not support the monophyly of the subfamily Metrodorinae with respect to Tetriginae. Consequently Metrodorinae might not represent an independent entity with respect to Tetriginae. © 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 164, 52–70.
