Fomoria degeeri

Diagnostic description: 

Diagnosis. Rather nondescript nepticulid moth, with narrow tornal spot, and without any androconial scales. Can be externally confused with some Ectoedemia (s. str.) species. Most similar to E. (Fomoria) deschkai, with rather similar male genitalia: E. degeeri differs in possessing three pairs of carinae compared to two in deschkai, and E. degeeri has two large cornuti, one of which has a serrated edge; E. deschkai has three large cornuti, none with serrated edge. The valval spine is elongate spinelike in E. degeeri and triangular in deschkai.

Morphology: 

Male. Forewing length 1.8-2.4 mm (3), wingspan 4.1-5.2 mm. Head: frontal tuft orange; scape cream with scattered brown scales; collar yellow; antenna greyish brown, 39-43 segments (2). Thorax and forewing irrorate blackish brown with white, most scales with dark tips; an indistinct narrow tornal spot cream white; cilia line distinct; terminal cilia greyish white to grey; underside almost black. Hindwing and cilia grey; no androconial scales; costal bristles present. Abdomen grey, with very small grey anal tufts, abdominal tip tapering.
Female. Unknown.
Male genitalia. Vinculum with distinct anterior emargination; ventral plate posteriorly produced into narrow tongue-shaped juxta-like process or ventral process, tightly fused to ventral carinae. Tegumen forming distinctly pointed pseuduncus, as long as uncus. Uncus with inverted Y-shaped medial process. Gnathos with rather short central element, broadly shouldered laterally. Valva more or less triangular, with short spinelike process originating on dorsal surface, pointing inward. Transtilla with long transverse bar and long sublateral processes. Aedeagus long and narrow, with three pairs of carinae: a ventral pair slightly outward-curved, approaching in middle, a rather long dorsolateral pair, and a dorsal pair approaching in middle, all connected by sclerotized rim; vesica with groups of small blunt cornuti and one long curved cornutus near phallotrema and another rather large serrated cornutus, serrated margin at left side in ventral view.
Measurements: capsule length 292-293 μm (2), valva length 191-195 μm (2), aedeagus length 321-330 μm (2), ratio aedeagus/capsule 1.1.
