Leptonema pseudocinctum

MALE.—Color basically brown; forewing brown, distinctly maculate with fuscous streaks and blotches (appearing identical to Mosely, 1933, frontis.). Length of forewing 20–23 mm.

Malar space rather broad, height of eye. Parafacial area half width of malar; postocular area width of parafacial, with an irregular row of 2–4 stout setae. Maxillary palpus with fifth segment long, only slightly shorter than basal four segments. Process of fifth sternum large, oblong, broader than long.

Genitalia: Tenth tergum with wart a large, erect, with setae borne from long papillae; warts b and c lacking; lateral lobe elongate, with a basolateral ridge; mesal lobe membranous. Clasper with apical segment very short, enlarged apically, with a dense pad of short, stout setae mesally; base of clasper unmodified. Phallobase basally angled obliquely to axis of stem, ending in an enlarged apex; apex with a small, erect, bifurcate process.

FEMALE.—Color similar to male, but forewing slightly larger: 20–25 mm.
