Diagnosis.
Belongs to the
S. magnispinella
group. The combination of very long lobes of uncus, small plate of gnathos, long ventral plate of gnathos without lateral lobes, and specific set of cornuti distinguishes
S. olekarsholti
from all members of the group, including the most similar Ecuadorian
S. varispinella
Diškus & Stonis.
Male
(
Fig. 33
). Described in Stonis
et al
. 2016: 569. Forewing length
1.8–2.6 mm
; wingspan
4.3–5.7 mm
.
Female
. Externally similar to male.
Male genitalia.
Illustrated in Stonis
et al
. 2016: figs 13–16.
Female genitalia.
Illustrated in Stonis
et al
. 2016: figs 33–35.
Bionomics
. Larvae mine in leaves of
Asteraceae
plant (an unidentified species). Larvae pale greenish grey with brownish grey head, mine in October (and probably in January–February). In the beginning, irregularly deposited blackish grey frass filling the most of the width of the gallery; further the gallery widened to a large elongated blotch with black frass distributed irregularly and with very wide unfilled areas of the blotch left (the leaf-mine illustrated in
Stonis
et al
. 2016f
: figs. 42, 43). Larval exit slit on upper side of the leaf. Adults fly in March and November.
Distribution
(
Figs 9
,
15–18
). Known from two localities in the Andean
Peru
(Dept.
Apurimac
and
Cusco
) at elevations about
2050–3500 m
(
Figs 15–18
).
