Ectoedemia (Ectoedemia) algeriensis

Figs 71, 79, 86, 88
Diagnosis
.
Resembles
E. quinquella
and
E. coscoja
, which both have a similar pattern of three spots, but the spots are usually less distinct in
algeriensis
.
E. coscoja
is separated by the pale head, and
E. quinquella
by the partially black thorax (anterior part), which is completely white in
algeriensis
, and the yellow hairpencil in
quinquella
, versus the white one in
algeriensis
.
E. algeriensis
has also many more antennal segments than the other two species.
Redescription
.
Male (Fig. 71). Forewing length 2.4–2.9 mm, wingspan 5.3– 5.7 mm. Head: frontal tuft almost black, collar slightly paler; scape white; antenna brown, with 48–54 segments. Th orax and tegulae completely white. Forewing brown, with pattern of two to three indistinct white spots, one at 1/3 at costa, one at dorsal margin slightly beyond middle and the third at 2/
3 in
disc, usually not touching costa, often reduced or almost absent; sometimes a small indistinct basal spot present; cilia-line distinct; cilia silvery white; underside light brown-grey. Hindwing and cilia dark grey; a white hairpencil, surrounded by yellow scales. Abdomen grey, with white anal tufts.
Female. Forewing length 2.1–2.6 mm, wingspan 4.9–5.6 mm; antenna with 27– 35 segments. Hairpencil absent, further as male.
Male genitalia (Fig. 79). Capsule
245–260 µm
long. Tegumen rounded. Gnathos with central element divided, distal part prominent, broadly spatulate, basal part with serrate margins. Valva length
195–215 µm
, inner margin concave, tip wide, strongly curved inwards and truncate, dorsal surface with few setae; sublateral processes about 1/3 length of transverse bar of transtilla. Aedeagus
250–275 µm
, carinae pointed, single, bi- or trifurcate.
Female genitalia (Figs 86, 88). T8 (and T7?) with more than 70 long setae, partly in row along anterior margin, no scales. Anal papillae with 24–28 setae. Vestibulum with vaginal sclerite, a prominent dorsal spiculate pouch, and a group of densely packed pectinations near entrance of ductus spermathecae. Corpus bursae
605–660 µm
without pectinations; signa dissimilar, longest
386–450 µm
(2), shortest
355–420 µm
, 3.5–3.9× as long as wide (2). Ductus spermathecae with 2 indistinct convolutions.
