Characters
. Head as large as long, ratio maximum width/length of head (from vertex to clipeus): 1.0. Squamipterous, pronotum rounded, slightly raised in the prozona, humeral excision just evident, median keel evident in the metazona; Ƥ subgenital plate with or without median furrow and right or incised at hind margin, lateral lobes rounded; ovipositor ca. ½ hind femur, thin, stout and strongly upcurved, similar to that of
Platycleis
; Ƥ VI–VII th sternites widely raised; hind femora/pronotum length 3: 2.6–4.3, Ƥ: 2.8–3.7;
3 X
th tergite with two more or less pointed short processes, cerci are just flattened. Basal arms of titillators with strong spines (only in
S. ankarensis
and
S. kurmana
there are small spines). Colour of lateral lobes of the pronotum is greyish or blackish; the white stripe is more or less distinct.
Remarks
.
Squamiana
species are associated with steppic zones of medium-high mountains (Tarbinsky 1939,
Pravdin 1969
,
Çiplak
et al.
2002
). The female of the
type
species (
S. squamiptera
) is characterized by the last tergite widely incised (
Uvarov 1912
). The genus appears heterogeneous and some species considered belonging to this taxon possibly should be better assigned to another one.
Çiplak
et al.
(2002)
pointed out that
Montana ankarensis
differs from other species of the same taxon by ovipositor
type
(basely light and dark in the rest, thick and more strongly upcurved) and wings shorter than pronotum. Somewhat similar to the
Squamiana
by ovipositor
type
, it differs, however, by unmodified VI and VII th sternites of female and apically wide tegmina. However, even though they were aware that this species does not belong to any described taxon, decided to maintain it within
Montana
. Afterwards,
Ünal (2006)
transferred it from
Montana
to
Squamiana
, mainly on the base of the shape of very shortened tegmina, the dark colour of ovipositor, except its base, and its shape (high, compressed and more upcurved).
Distribution
. Central Asia to
Turkey
.
