Genus Cymolomia

Cymolomia Lederer
Type species: hartigiana Saxesen

DIAGNOSIS

External characters:

Venation:
venation Cymolomia hartigiana
Forewing: All veins separate; chorda extending from mid-distance R 1-R 2 to base of R 5; median stem to base of M 3.
Hindwing: M 3 and CuA 1 shortly stalked.

Forewing shape and markings:
Cymolomia hartigiana adults
Cymolomia hartigiana : forewing dilated posteriorly; costa gradually arced; termen slightly oblique. Markings consisting of irregular fasciae.

Additional characters:
Long pencil of scent scales on posterior tibia, and hair like scales at base above; anal part of hindwing rolled downwards, slightly projecting distally.

Genitalia:

Male:
male gen. C. hartigiana
Uncus short, bilobed or weakly concave apically, armed with subterminal spines ventrally; socius large, usually drooping, hairy; basal sclerite of tuba analis bilobed, extending medially to form a short subscaphium, or membranous. Valva with long cucullus, extending ventrally into a densely spined fold; sacculus with groups of hairs or spines situated anteriorly, and if developed, also medially.

Female:
female genitalia C. hartigiana
Sterigma well developed, aciculate, consisting of a tubular prominence surrounding ostium bursae and extending laterally and ventrally into a variably shaped plate; usually its lateral parts are large, elongate or rounded, with a tendency to be membranous ventro-medially. Colliculum provided with elongate sclerite; ductus bursae often weakly sclerotized medially; ductus seminalis situated posteriorly; signum single, funnel-shaped.

Early stages:

Swatschek, 1958, provides the following diagnosis for the larvae based on chaetotaxy of Cymolomia hartigiana.
Crochets on abdominal prolegs biordinal; on A9 D2 setae on separate pinacula. Seta V1 is clearly distanced from coxa on metathorax. SV group trisetose on A1-7, bisetose on A8-9.

Biology:

One generation yearly. Young larvae of Cymolomia hartigiana mine the needles of Abies and Picea, later spinning them together; other species feed on Ledum, Pirola etc.

Distribution:

Palaearctic and Oriental regions.
