Abstract: The description of a new species of the genus Acanthops Audinette-Serville, 1831 from Ecuador is given. A. septemspinosa n. sp. is the eighteenth species of this genus; it is distinctive from the other species known so far because of the unusual shape of the external male genitalia.
Key words: Mantodea, Acanthops septemspinosa, new species, Ecuador.

Resumen: Se presenta la descripción de una nueva especie de Acanthops Audinette-Serville, 1831 de Ecuador. A. septemspinosa n. sp. es la decimoctava especie del género. Se distingue de las restantes especies conocidas por la inusual forma de
la genitalia externa masculina.

Taxonomy/Taoxnomía: Acanthops septemspinosa n. sp.
Introduction
Among the Acanthopinae belonging to Lombardo’s collections I discovered a specimen from Ecuador belonging to
the genus Acanthops Audinette-Serville, 1831. The different
shape of the wings and the external male genitalia has
shown notable differences from those of other species of
Acanthops, therefore it is necessary to institute a new species.
ETYMOLOGY. This species is named for the presence of
seven spines on the external margin of the anterior femora.
DESCRIPTION.
Head. Chestnut with small brown spots, 1.66 times as wide
as pronotal dilatation (Fig.1); eyes conical with distinct
apical tubercle; frons concave; antennae short ochreous;
ocelli large; fastigium of vertex lower than imaginary line
joining apex of eyes; frontal shield transverse, upper margin
with two distinct teeth projecting forward; disc granulous;
anteclypeus and postclypeus separated by a middle transversal carina. Labial and maxillary palpi ochreous.
Thorax. Pronotum elongated (Fig.1), 1.64 times as wide as
minimum width of metazona; smooth lateral margins, disc
with numerous scattered granules; supracoxal dilatation
moderately enlarged. Prosternum ochreous anteriorly to
coxal sulcus and posteriorly dark with light scattered granules. Anterior coxae 0.78 times as long as pronotum, prismatic with a quadrangular section; internal surface with
ivory calluses; posterior surface with a mammelliform ivory
tubercles; lateral margins spinulated. Trochanter with
ochreous granules. Anterior femora (Fig.2) 4.57 times as
long as their maximum width; external surface with sparse
granules, upper margin straight; 7 external spines, 4 discoidal spines, 17-19 internal spines all ochreous with black
apex. Anterior tibiae with 18 internal and 26 external
slipped spines all brown with black apex. Middle and hind
legs slender with elongated hairs; posterior metatarsa
shorter than the other together articles. Wings well developed, extending beyond apex of abdomen. Mesothoracic
wings opaque brown, costal margin sinuous with not well
developed excavation; apex with small lobe; costal area
enlarged to base until to 2/3 of its length. Discoidal area
with shiny brown stigma. Metathoracic wings hyaline,
Material and Methods
This study is based upon one single male specimen from
Ecuador, the only specimen known until now.
Drawings were made using a Leica M28 stereomicroscope provided with camera lucida. Anatomical terminology
follows Snodgrass (1935) except for the copulatory apparatus which follows La Greca (1954). Measurements were
made using a Leitz stereomicroscope.
The specimen is deposited in the Museum of the Department of Animal Biology “Marcello La Greca” University of Catania (DBUC).

Figs 1-9
DIAGNOSIS. Medium in size, eyes ovoid with a small conical tubercle, pronotum elongated, anterior femora with
seven small spines on external margin. Tegminae opaque
with anterior margin sinuous with a moderately deep excavation; stigma shiny brown. Abdomen moderately enlarged
with a leaf-like lobe on external margin.
Female unknown.
TYPE MATERIAL. Holotypus ♂: Ecuador: Napo, Yasuni,
200m, 10.Nov.1997, Lombardo leg. (DBUC).

Habitus.

between these two genera cannot be based only on the number of spines of the anterior femora (six in Acanthops and
seven in Metilia), as this character is quite unstable, but on
other characters such as: the shape of the pronotum that in
Acanthops is never stumpy as in Metilia; the frontal shield
that in Acanthops always has two distinct teeth on the superior margin and the presence of lobular protuberance on the
lateral margin of the 4th urosternite that in Acanthops is very
wide.
chestnut in colour except a preapical diaphanous streep
(Fig. 9).
Abdomen. Moderately enlarged, 4° urotergites with an
enlarged leaf-like lobe on external margin (Fig.3). Supranal
plate short, trapezoidal in shape, cerci with long hairs (Fig.4).
External genitalia. Ventral phallomere (Figs 5, 6) longer
than wide, anterior process well developed, narrow and with
acute apex. Left phallomere well sclerotized: dorsal lamina
(Fig.7) not well developed, with a large membrane with
numerous hairs of different length; ventral lamina (Fig.8)
well developed, left margin with numerous digitations.
REMARKS. This species corresponds well to the diagnosis
of the genus Acanthops and, in particolar, it is close to A.
tuberculata Saussure with which it shares the same number
of spines on the external margin of the anterior femora, it
differs, however, clearly from it for the shape of the wings
and genitalia. A. septemspinosa n.sp. and A. tuberculata
are, to our knowledge, the only two species of the genus
Acanthops that have 7 spines on the external margin of the
anterior femora, a characteristic that, for a long time, has
been used to distinguish the genera Acanthops and Metilia.
As has recently been observed by Roy (2002) the distinction
