Atomopteryx solanalis

Name

Atomopteryx solanalis (Barnes & McDunnough, 1913)

Common name: none

Original combination: Stenoptycha solanalis Barnes & McDunnough, 1913

Synonyms: none

Alternative combinations: none

Classification: Pyraloidea: Crambidae: Spilomelinae, Leucinodes group

Adult recognition

Forewing length: 7.5 - 9.0 mm, narrow. The wing pattern is solidly pale brown, without contrasting areas of white or dark brown. The faint, blackish PM line undulates across the wing with a shallow concavity on the medial veins. In the hind wing venation, one of the medial veins is lost. In the male genitalia, the valva has a short fibula that is apically swollen with a small, down-curved tooth, and the sacculus has a triangular window. In the female genitalia, the colliculum is close to the corpus bursae (that is, the antrum is elongate and the ductus bursae is short).

Immature stages

Not described.

Similar species

Atomopteryx pterophoralis is widely distributed in the Caribbean, Central and South America. The plain brown wing pattern is similar to A. solanalis, but male A. pterophoralis lack a fibulum. In Puerto Rico, it has been reared from Solanum torvum leaves (Medina Gaud and Martorell 1970).

Behavior

A leaf-tier. Collected together with Lineodes integra.

Distribution

USA: Florida. Rare; most common in the Florida Keys. Also in the Bahamas and Cuba.

Hosts

Solanum verbascifolium” (USNM)

Solanum sp. (original description)

Comments

This species was described from southern Florida. It was synonymized by Dyar (1913) with A. pterophoralis but considered to be a good species by Munroe (Kimball 1965). Specimens identical to A. solanalis also have been collected in Cuba, along with other species that differ as indicated under Similar Species.
