Bidzilya) (MHNG).</p><p><b>Diagnosis.</b> Forewings with costal and dorsal medial spots connected forming oblique transverse line is characteristic for <i>S. lobata</i> <b>sp. nov.</b> (in <i>S. davidi</i> <b>sp. nov.</b> these spots are close to each other, but separated and do not form fasciae; additionally, <i>S. davidi</i> <b>sp. nov.</b> has pale rather than light brown ground colour of the forewing). The male genitalia of <i>S. lobata</i> <b>sp. nov.</b> resemble those of <i>S. davidi</i> <b>sp. nov.</b> and <i>S. harambee</i> <b>sp. nov.</b>, as all of them have glandiductor with broad, rounded membranous basal part, but <i>S. lobata</i> <b>sp. nov.</b> has cucullus of even width and apically narrowed uncus (in <i>S. davidi</i> <b>sp. nov.</b> and <i>S. harambee</i> <b>sp. nov.</b> basal part of cucullus is 1/2–1/3 width of distal part and uncus is of even width). Female genitalia <i>S. lobata</i> <b>sp. nov.</b> are characterized by trapezoid, posteriorly undulated ostial sclerite (in <i>S. harambee</i> <b>sp. nov.</b> ostial sclerite is rounded). Also, in <i>S. lobata</i> <b>sp. nov.</b> corpus bursae is spinose both on its posterior part and along lateral side (in <i>S. palescens</i> <b>sp. nov.</b> corpus bursae is spinose only on its posterior part).</p><p><b>Description</b> (Figs 13–15). Wingspan 6.5–7.0 mm. Head pale, frons with brown-tipped scales; labial palpus recurved, segment 2 brown mottled with yellowish-white and with white apex; segment 3 brown with white basal and apical rings; antennal scape brown with white apex, lower surface white, flagellum in basal half brown on upper surface and pale beneath, in distal half 4 white flagellomeres followed by 4 brown, and then 1–2 white alternating with 3–4 brown, terminal 1–2 flagellomeres white; thorax and tegulae yellowish-brown; forewing yellowish-brown, costal margin brown with brown spot mottled with silver just after middle that is connected with brown spot on 1/2 of dorsal margin, dorsal margin with sparse brown-tipped scales, apex brown mixed with silver-tipped scales and spotted with yellow, tornal spot on 3/4 rounded to irregular, mottled with silver, with distinct black dot inside; fringe yellow on apex of the forewing and grey on dorsal margin; hindwing and fringe light grey.</p><p><b>Male genitalia</b> (Figs 37, 38). Uncus slender, elongate, parallel-sided to 3/4, then narrowed towards pointed apex, densely covered with modified feather-like scales and strong setae distally, twice as long and about 1/2 width of tegumen, extending to 2/3 length of cucullus; tegumen slightly elongated, anterior margin broadly rounded, produced anteriorly; cucullus digitate, of even width, ventral margin weakly convex, densely covered with hair-like scales, apex rounded; glandiductor with rounded membranous basal part, distal process weakly curved, apex divided in three slender projections, extending to about 2/3–3/4 length of cucullus or slightly extending top of cucullus; juxta subrectangular, posterior margin straight; vinculum slightly broader than long; saccus broadly rounded; phallic tube of equal width, straight, shortly constricted on 2/3, apex with very slender flagellate process.</p><p><b>Female genitalia</b> (Fig. 45). Papillae anales ovate, sparsely covered with short hairs; apophyses posteriores straight, thin, 2 times longer than apophyses anteriores; sternum VIII subrectangular, broad, ostial sclerite narrow, trapezoid, undulated posteriorly; apophyses anteriores straight, about 1.5 times longer than sternum VIII; ostium Ushaped; ductus bursae slender in middle; corpus bursae moderately elongate, ovate, covered with minute spines in posterior part and to 3/4 along one side, signa represent by band of 15–18 needle-shaped signa between membranous and spinose parts of corpus bursae.</p><p><b>Biology.</b> Host plant unknown.
