Diagnosis. Scrobipalpomima phalluspinosus show no clear relationship with any specific congener ( Povolný 1985, 1989b, 1990). The new species can be easy distinguished by the following character: phallus with 3-5 well-defined micro-spines at the apex (Figs. 14-16).
Description. Male. Head: Frons and vertex covered by brownish light scales, occiput covered with elongated brown scales. Labial palpus brownish, with ventral brush of dark scales on second segment, medial white band near middle, third segment strongly curved with weak medial band. Antennae dark, with densely ciliate flagellomeres. Thorax: Nota and tegulae covered with brown scales. Forewing length 5.5-7.5 mm (n = 3), brownish gray, more or less densely dusted with yellowish scales, with subapical fascia. Hindwing whitish; fringe yellowish. Genitalia ( Figs. 10 -16) with uncus wide, triangular, with prominent pointed margin. Gnathos slender and digititate. Valva elongated, moderately curved, with rounded apex, longer than saccus. Sacculus V-shaped with media incision, saccular processes with margin truncated anteriorly, parabasal processes extending slightly beyond tip of saccular pair, moderately lobed. Saccus longer than wide, prolonged, with acute apex. Phallus moderately short, narrowed, with 3-5 strongly defined spines in apex; coecum well defined, not bulbous, approximately 1/2 length of phallus. Female. Unknown.
Host plant. Unknown.
Intra-specific variation. The species varies in the male genitalia, with subtle differences in form and numbers (3-5) of spines at the apex of the phallus.
Etymology. The specific name refers to the micro-spines in the apex of the phallus.
