Diagnosis.
Externally
P. paragallicella
is somewhat similar to
P. ericella
(Duponchel, 1839)
(
Fig. 15
), but the subcostal line is paler brown, the labial palp markedly longer, and the veins in hindwing well visible. In male genitalia,
paragallicella
is close to
P. gallicella
(
Fig. 49
) with some distinct differences. In
paragallicella
, the gnathos is longer, the posterior lobe shorter, and the valval lobe markedly smaller, subtriangular (in
gallicella
the valval lobe is ear-shaped). The female of
paragallicella
is unknown.
Molecular data.
The
holotype
of
paragallicella
was sequenced successfully, resulting in a 656 bp barcode sequence. The nearest neighbour to
paragallicella
is
P. gallicella
, with a 5.13 % divergence.
Description.
Adult. Wingspan
16.7 mm
. Labial palpus long, 8.2 x diameter of eye (1
st
and 2
nd
palpomeres), 3
rd
palpomere 0.23 x length of 1
st
and 2
nd
palpomeres, dirty white, scattered with brown and pale beige scales, below dark brown, mixed off-white. Antenna and scape brown. Head, thorax and tegula brown, mixed with fuscous and off-white scales. Forewing dirty white, scattered with pale fuscous and brown scales; costal line off-white, from base to 0.75; subcostal line greyish brown, expanded towards apex, brown, scattered with white and dark brown scales. Fringe greyish brown, apically lighter. Hindwing greyish brown, veins visible, fringe concolorous, apically white.
Male genitalia. Uncus triangular from ventral view, slightly shorter than gnathos, lined with several long and short bristles, apex with stout protuberance. Gnathos funnel-shaped from ventral view, broad, smooth, distal half elongate and covered with scobination, apex stout. Valva oblique from ventral view; cucullus moderately narrow, ventral margin concave; sacculus covered by long bristles; valval lobe very small, subtriangular. Anterior extension of juxta narrow; posterior lobe not reaching the base of uncus. Phallus arched, slightly tapered towards apex, with a large plate-shaped cornutus and numerous robust spines grouped into two bundles of different size.
Female genitalia. Female unknown.
Biology.
The biology is unknown. The specimen was collected at light on a rocky hillside.
Etymology.
The specific epithet refers to the close affinity with
gallicella
.
Distribution.
Known only from the
type
locality in the High Atlas Mountains at an altitude of
2400 m
.
Note.
Huemer & Luquet (1995)
included five
Pleurota
specimens from Tinmel,
Morocco
into the
paratype
series of
gallicella
,
but these specimens may belong to
paragallicella
(not examined by us). Tinmel is a village situated about
40 km
southwest of Tizi n’Addi, the type locality of
paragallicella
.
