Chopardiella
Giglio-Tos, 1914
Uromantis amazonica
and
Uromantis paraensis
were both simultaneously described by
Jantsch (1985)
. However, at the time of their description, Jantsch ignored the fact that
Uromantis
, as well as other similar genera created by
Giglio-Tos (1917)
, were all already placed under synonymy with
Stagmomantis
Saussure, 1869
by
Hebard (1923)
, an action that
Rehn (1935)
and subsequent authors later followed. Accordingly,
Terra (1995)
formally transferred both
amazonica
and
paraensis
to
Stagmomantis
, a procedure he likely undertook under the “safe” assumption that Jantsch had correctly assigned his two new species to
Uromantis
. We examined the
holotypes
of both of Jantsch’s species deposited at INPA and recognized that those characters Jantsch used to justify both individuals as separated species, such as relative body length, relative density of the minute denticles on the pronotal edges, and wideness of the costal area of the mesothoracic wings, are all of no use. Fortunately, both specimens have their genitalia intact and they proved to be virtually identical upon close examination (
Fig. 10
a–b, d–e). Therefore, we regard
U. amazonica
and
U. paraensis
as conspecifics (
Fig. 10
c–f). Furthermore, we compared the external morphology and male genitalia of Jantsch’s species to that of
Chopardiella latipennis
(
Chopard, 1911
)
(
Fig. 11a
–b) and could not find any relevant difference that may justify the validity of all these names, as they are all clearly conspecifics. Thus, we establish both
U. amazonica
and
U. paraensis
as synonyms of
C. latipennis
. The following taxonomic changes now apply:

Chopard, 1911

Chopard (1911)
described his new species
Pseudoxyops latipennis
based on a single female from Nouveau- Chantier, in
French Guiana
. However,
Giglio-Tos (1914)
considered that this species should be included in its own genus and thus created
Chopardiella
Giglio-Tos, 1914
to accommodate it, using simply Chopard’s illustration to justify his new taxon while acknowledging the fact that he had not seen specimens of
P. latipennis
. We consider that those characters used by Giglio-Tos to justify
Chopardiella
represent interspecific rather than intergeneric differences, particularly in regard to the small distal lobes on the mid- and hind femora, which are absent in
Pseudoxyops
. It was not until
Lombardo (1994)
described the male of
P. latipennis
that sexual differences in the degree of lobe development became notorious; whereas the female does exhibit a conspicuous distal lobe on both mid and hind femora, such a lobe is almost nonexistent in males, in which it is barely indicated by a slight undulation of the cuticle. We have observed this same feature in various male specimens from museums and in material obtained from
French Guiana
. Another feature that Giglio-Tos used to separate
Chopardiella
from
Pseudoxyops
was the shape of the compound eyes, which are spherical in
Chopardiella
but conical in
Pseudoxyops
. We also regard this character as invalid for making such distinction because eye shape and other ocular modifications (e.g. apical spurs and non-visual elongations) are known for exhibiting wide variation among congeners and even intraspecifically, as observed in representatives of various genera, such as
Ameles
,
Heterochaeta
,
Compsothespis
, among many others (
Wieland 2013
). On the other hand, the shape of both the pronotum and the mesothoracic wings of the female, and similarities in the shape of male genitalia (see
Lombardo 1994
,
Lombardo & Agabiti 2001
,
Battiston & Picciau 2008
for comparison), suggest that
C. latipennis
(
Fig. 11a
),
C. poulaini
Lombardo & Agabiti, 2001
and
Pseudoxyops
are all closely related, most likely representing a single evolutionary line.
Pseudoxyops
includes five species from which very little is known, except perhaps for the Amazonian
Pseudoxyops perpulchra
(Westwood, 1889)
(
Fig. 11
b), the most commonly cited and collected species.
Battiston & Picciau (2008)
recently identified and described the miniaturized male of this highly dimorphic species. We suggest that the two species currently included in
Chopardiella
should be transferred to
Pseudoxyops
and the former put under synonymy with the latter. Unfortunately, all other species of
Pseudoxyops
(
P. diluta
,
P. boliviana
,
P. minuta
,
P. borelli
) are mostly known only from their original descriptions, and even though their morphology differs in many respects from that of
P. perpulchra
, we refrain from establishing such synonymy, since
Pseudoxyops
, as currently conceived, is in need of re-evaluation to verify the taxonomic status of its less-known species. We will leave this question open to consideration, pending future studies.
