Rambur, [1866]

Catalogue Systématique des Lépidoptères d´Andalousie

Diagnosis.
Imago.
Forewings narrow, with a pale costal stripe. Superficially, like many other groups of
Eilema
sensu lato
.
Male genitalia
: Uncus of medium size, slender, cylindrical, not flattened, of moderate width, with a pointed tip; valvae oval or apically restricted; cucullus clearly separated from apex of sacculus, clasper absent; superior part of the juxta basically flat, without lateral apical processes (present in
Manulea
and
Eilema
); vinculum of medium size, rectangular (trapezoidal in
Manulea
)
, membranous with finely sclerotised margins. Aedeagus generally short and stubby, with one to three spike-shaped cornuti usually the same size; no apical spur.
Female genitalia:
Anal papillae well developed, weakly sclerotised with short anterior and posterior apophyses; A8 wide, short and slightly sclerotised; lamella postvaginalis absent or obsolescent; ostium bursae bell shaped, membranous and broad; ductus bursae short, wide and slightly sclerotised; corpus bursa spherical, membranous, with one small rounded signum; cervix bursa inconspicuous and almost without warts or spinules inside.
Molecular data.
The clade encompassing the seven species included in the genus
Indalia
received a strong BI tree support (PP=0.99) and, as mentioned earlier, shows considerably low between-group distances (TN-dist from 2.93% to 7.90%; average = 5.80%). This clade also includes the genus
Setema
and the genus
Nyea
, which appear closely related but with distinct morphological characteristics. Pairwise distances are higher and variable within
Indalia
than in
Manulea
(TN-dist from 3.93% to 4.86%; average = 4.49%).
The extended phylogenetic analysis -including our sequenced mitochondrial and nuclear markers plus additional COI data from BOLD- maintains the consistency of this group (
Fig. 120
), as only sequences attributed to the American
Setema bicolor
appear in close proximity of the other two analysed species of this genus (
Setema debilis
and
Setema cereola
).

Taxa included
The
predotae
group
Indalia marcida
(
Mann, 1859
)
comb. nov.
Indalia predotae
(
Schawerda, 1927
)
comb. nov.
It comprises two species with a very similar genitalic structure (cucullus separated from sacculus apex, aedeagus with three small cornuti of equal size, vinculum wide, elongated with parallel margins and with no clasper).
Indalia predotae
is endemic to the Iberian Peninsula where it can be found in xerothermic biotopes at lower elevation than
1200–1300 m
, whereas
Indalia marcida
is a central-western mediterranean species, with colonies near the coast and not higher than
500–
600 m
. Although in
Italy
,
Indalia marcida
is mainly linked to central and southern coastal areas. In southern
Italy
it is not found below an elevation of
600 m
while in
Sicily
it is clearly restricted to mountainous areas reaching elevations above
1100 m
(
Grassi & Zilli, 2005
).
