Diagnosis.
Based on its male genitalia,
Scrobipalpominia manuscriptus
is most closely related to
S. improbabilis
Povolný (1989b)
; both species lack spines on phallus. This new species can be differentiated from
S. improbabilis
by the prominent margin of the uncus, the dilated apex of the valva, a longer gnathos, an elongated saccus, and the phallus narrowed with an ovoid coecum.

Labial palpus whitish, with ventral brush of dark scales on second segment, third segment strongly curved with some scattered dark scales. Antennae with dark scape and densely ciliate flagellomeres. Thorax: Nota and tegulae covered with dark brown scales. Forewing length
6-9 mm
(n = 3), ashy gray, more or less densely dusted with black scales, with few yellowish scales at base of cell and continuing towards middle of wing. Hindwing whitish; fringe yellowish. Genitalia (

Sacculus U-shaped with media incision, saccular processes digititate, parabasal processes extending slightly beyond tip of saccular pair and moderately curved internally. Saccus longer than wide, prolonged, with acute apex. Phallus, narrowed, lacking elongate spines; coecum well defined, ovoid, approximately 1/4 length of phallus. Female. Unknown.
