Diagnosis
.
S. paniculata
sp. nov.
belongs to the
Stigmella ruficapitella
group. In the male genitalia, this new species differs from other representatives of the group in the presence of a basal set of very long, transverse cornuti (
Fig. 135
) and apically rounded valva without a conspicuous apical process (
Fig. 136
).
Male
. Known from adult in pupal skin; only genitalia are preserved and desribed.
Genitalia
(
Figs 133–136
) with capsule
180 µm
long,
140 µm
wide. Uncus with two very short, well-separated lateral lobes (
Figs 133, 134
). Gnathos U-shaped (
Fig. 133
). Valva (
Fig. 136
) about
130 µm
long, with a slightly concave and heavily papillated inner lobe and rounded apex without pronounced apical process. Transtilla with long and slender sublateral processes. Vinculum with a short ventral plate and short triangular lateral lobes (
Fig. 133
). Phallus (
Figs 133, 135
) about
180 µm
long, without carinae; vesica with a set of four very long, transverse cornuti basally (
Fig. 135
).
Female
. Unknown.
Bionomics
(
Fig. 15
). Host plant is unknown (unidentified). Larva is green, with a dark green intestine and pale, yellowish brown head (
Fig. 15
). Larvae mine in leaves in late August and possibly in September. The leaf mine is a slender, contorted gallery; in the initial part, brown-black frass fills the width of the gallery; further on, black frass is deposited in a slender central line (
Fig. 15
). Adults fly in September.
Distribution.
Known from a single locality in the western Himalaya (
Uttarakhand
: Chamba), at the elevation of about
2600 m
(
Fig. 1
:
wHi
).
Etymology.
The species name is derived from Latin
panicula
(a cluster), in reference to the set of four very long and slender cornuti in the male genitalia.
