material.
Holotype
: ♂, Far East
RUSSIA
, Primorskiy Kray,
20 km
E Ussuriysk, Gornotayezhnoe, Biological Station,

, leg. A. Rocienė, genitalia slide no. AG428 (

).
Diagnosis.
This species belongs to the
Ectoedemia suberis
group and to most closely resembles the other recently described East Asiatic species,
E. ortiva
Rocienė & Stonis. Both
species (
E. ortiva
and
E. paraortiva
sp. nov.
) differ from other
Ectodemia
by the broad phallus with numerous spine-like cornuti. The new species (
E. paraortiva
sp. nov.
) differs from
E. ortiva
by the absence of a fascia on the forewing (
Fig. 22
) (in
E. ortiva
the fascia is well developed, see
Fig. 24
), also by the more grey hindwing with a long, weakly visible hair-pencil, which is not surrounded by a yellowish cream patch of androconia (
Fig. 23
) (in
E. ortiva
this patch is very characteristic, see
Fig. 25
) (also see Remarks).
Male
(
Figs 22, 23
). Forewing length about 2.0 mm; wingspan about 4.4 mm. Head: palpi grey-cream; frontal tuft pale orange; collar whitish, comprising loose lamellar scales; scape cream; antenna with 30 segments, almost half as long as forewing; flagellum grey on upper side and underside. Thorax: dorsum and tegulae concolorous with base of forewing. Forewing grey-brown, apically more coarsely speckled with darker scales; fascia absent; cilia pale grey-brown; underside of forewing uniformly dark grey-brown. Hindwing (
Fig. 23
) brownish grey or dark grey on upper side and underside; hair-pencil slender and long (longer than half of hindwing), but not prominent (hardly visible), grey-cream (but not surrounded by a patch of cream androconia as in
E. ortiva
,
Fig. 25
); costal margin remains brownish grey; cilia pale grey to grey. Legs brown-cream, shaded dark brown on upper side.
Male genitalia
(
Figs 26
,
28–30
). Capsule longer (
270 mm
) than wide (
180 mm
). Vinculum very broad (
180 mm
), with two very short but very broad lateral lobes (
Figs 26
,
28
). Pseuduncus triangular (
Fig. 28
), damaged in genitalia slide no. AG428 (
Fig. 26
). Gnathos with long lateral arms and slender caudal process (
Fig. 28
). Valva (
Fig. 29
)
170 mm
long, curved inwardly, gradually narrowed towards apex, with pointed apical process; transtilla with slender and long sublateral processes (
Figs 26
,
28
). Phallus (
Fig. 30
) broad (
100 mm
),
220 mm
long, with two apical carinae; vesica with numerous spine-like or similar cornuti of different sizes (
Fig. 30
). Although the phallus of
E. paraortiva
sp. nov.
tends to be slightly smaller than that of
E. ortiva
, the new species is not distinguishable on basis of the phallus (see comparison of
E. ortiva
and
E. paraortiva
sp. nov.
in
Figs 30, 31
);
Female.
Unknown.
Bionomics.
Host-plant unknown; possibly a leaf-miner on
Quercus
(as the other species of the
Ectoedemia suberis
group). The only known specimen was collected in early August (attracted to light).
Distribution
. The
type
locality is in dense, deciduous mostly broad-leaf forests of Primorskiy Kray (
Figs 1–5
).
Etymology.
This species is named after
Ectoedemia ortiva
Rocienė & Stonis
, a closely similar (and presumably closely related) species recently described from the same locality in Primorskiy Kray as the new species (see Rocienė & Stonis 2013).
Remarks.
We suppose that
E. ortiva
and
E. paraortiva
sp. nov.
are probably two sympatric species.
