Hosts.
Ranunculaceae
:
Helleborus
Tourn.
ex L. (
Benavent-Corai
et al

).
Clematis
sp.
—a newly recorded host plant.
Mine.
(
Fig. 197
) The larva forms an upper surface blotch mine. Pupation takes place within the mine, in a “pupal blister” (
Fig. 198
).
Puparium.
(
Figs. 199–201
) Greyish-brown, silky shining,
2.5 mm
long, with distinct segmentation; surface quite smooth except for narrow bands of fine spines bands and the last two abdominal segments finely wrinkled. Posterior spiracles set on long conical protuberances that are entirely separate; black, glossy and sickle-shaped. Anal plate brown, strongly protruding above the surface of puparium viewed from the side and directed posteriorly.
Cephalopharyngeal skeleton.
(
Fig. 572
) Right mouthhook larger than the left, each with distinct abducted portion directed ventro-anteriorly and bearing two accessory teeth. Intermediate sclerite short, its length equal to the maximum height of the left mouthhook. Small parastomal bar exist. The mouthhook, the intermediate sclerite and most of the dorsal cornu are strongly sclerotized; the dorsal cornu dorsally and ventrally and the ventral cornu are much less so. The ventral cornu bears a “closed” window located centrally. Indentation index 86.
Female head.
(
Figs. 573, 574
) Yellowish-rose, with only antenna, palpus, postgena posteriorly and hind margin of eye brown; orbit projecting above eye in profile; 2 orb s, 1 fr s; lunule low, broad, semicircular, reaching the level of the anterior fr s; pped large, rounded; gena medially 0.28× as high as maximum height of eye.
Female genitalia.
(
Figs. 575, 576
) Capsule of spermatheca medium-sized, 0.23× as high as height of anterior part of oviscape. Spermathecae unequal in size, brown, spherical, flattened basally. Internal duct invagination cylindrical, as deep as height of spermatheca. Spermathecal duct weakly sclerotized. Ventral receptacle S-shaped, with well sclerotized tail that is two-bladed in basal half. Body of receptacle spherical with uniformly curved basal connecting tube, strongly sclerotized, 0.76× as wide as capsule of larger spermatheca; with narrow opening, 0.44× as wide as diameter of spherical part of body.
