Parnassiana vicheti
from Mediterranean
France
has been tentatively ascribed to
Parnassiana
(cf.
Delmas & Rambier 1950
;
Chopard 1951
), but its affinity with Balkan
Parnassiana
is questioning and recently
Heller (2006)
has hypothesized that it probably belongs to a different taxon. It shows the pronotum comparatively longer than other species of
Parnassiana
and other characters which consent to treat it within a separate taxon. Additionally, its song is more related to a
Metrioptera
than to a
Parnassiana
(K.-G. Heller, pers. comm.). Thus, we consider the French taxon not belonging to any described genus and name it
Amedegnatiana
new genus
.
Description
. Head just larger than long, ratio maximum width/length of head (from vertex to clipeus): 1.1–1.2. Micropterous, pronotum is comparatively longer than in taxa ascribed to
Parnassiana
(ratio length/height of pronotum 3Ƥ: 1.4–1.5), flat, humeral excision just evident, hind border of pronotum well protruding over the metanotum, keel present. Ƥ subgenital plate has a just incised hind margin and the ovipositor is stout and greyish, ca. 1.3– 1.4 as long as pronotum and laterally compressed. Ƥ VI–VII th sternites are not modified; hind femora very short, hind femora/pronotum length 3Ƥ: 2.3–2.4;
3 X
th tergite depressed in middle and deeply incised, processes are triangularly pointed. Cerci are rounded and provided with an inner teeth in the fourth portion. Titillators folded at right angle, their basal arms with spines. Colour of lateral lobes of the pronotum is black bordered with a white stripe.
Derivatio nominis
. The genus is named after the late French orthopterist Christiane Amedegnato, who some years ago nicely received us in the Museum of Natural History of Paris.
Remarks
. Well characterized by long metazona, humeral excision just evident, very short hind femora, male processes of X th tergite, female subgenital plate and short and stout ovipositor.

Characters
. Micropterous, pronotum rounded, excision just evident, median keel more or less evident; Ƥ subgenital plate small, straight on hind margin, raised in the middle near the base, with a shallow comma-shaped furrow; ovipositor ca. ½ hind femur, well curved upwards; Ƥ VII th sternite enlarged, with two sublateral tubercles; hind femora/pronotum length 3Ƥ: 3.1–3.3;
3 X
th tergite with short processes, in the middle with a narrow longitudinal groove behind hind margin carinate, cerci cylindrical with pre-apical tooth. Colour of lateral lobes of the pronotum is blackish-grey bordered with a white stripe.
Distribution
. Central Asia.
Remarks
. This altomontane genus is probably related to
Squamiana
.
Bei-Bienko (1951)
described two species of ‘
Metrioptera
’,
atroflava
and
crassipes
; while he included the former in the subgenus
Alticolana
, was not able to decide the supraspecific taxon of the latter (of which only the female was available) and wrote
Metrioptera
(
?
)
crassipes
, because it was characterized by the subgenital plate transverse, smooth, with straight hind margin, seeming obtuse emarginate from below. In addition,
Bei-Bienko (1951)
pointed out that it was a little related to
Eumetrioptera
by its short hind femora (hind femora/pronotum length: 2.1–2.4); the ovipositor shape is similar to that of
Pravdiniana
, but the subgenital plate is different from it.
Ragge (1990)
correctly included only two species within the taxon
Alticolana
,
alticola
and
atroflava
. The first author who listed
crassipes
within
Alticolana
was
Otte (1997)
, followed by
Eades & Otte (2008)
and
Eades
et al.
(2010)
. We think that this species does not belong to
Alticolana
, but in the absence of the male, we leave it in this genus.
