( Figs. 11 View FIGURES 7 – 14 , 27, 28 View FIGURES 23 – 28 , 36 View FIGURES 36 – 40 )

Type material. Holotype, 3, TANZANIA, Iringa Region, Mufindi District, Kigogo Forest 1900 m., 23–25.xi.2005, leg. L. Aarvik, M. Fibiger, A. Kingston, genitalia slide 2724 L. Aarvik ( NHMO). Paratypes: 33, 1Ƥ, same data as holotype, female with genitalia slide 2722 L. Aarvik (23 LAA; 13, 1Ƥ NHMO).

Description. Adult. Male ( Fig. 11 View FIGURES 7 – 14 ). Wingspan 15.0–16.5 mm. Head: Dirty white. Antenna brownish grey, scape dirty white above. Labial palpus 1.5 times diameter of eye, externally dark grey, internally light grey; rather slender as scaling of second segment is less pronounced than in other species, third segment drooping. Thorax: Anteriorly greyish white, greyish brown medially, with distinct white posterior spot; tegulae brown. Legs brownish grey, tarsi with paler rings. Forewing upperside with basal 2/3 blackish brown; terminal 1/3 ochreous; on dorsum two white marks; the inner mark reaching to about 2/5 from dorsum, the distal one sharply pointed, reaching to 1/3; a white dot present somewhat beyond distal white mark, and one between wing base and inner white mark; a few dark scales present in terminal area. Hind wing upperside dark brownish grey; ochreous hair-pencil from base of hind margin to scale cover on dorsum of abdomen. Abdomen: Grey, abdominal brush dark grey above and beneath, laterally light yellowish grey. Male genitalia ( Fig. 27 View FIGURES 23 – 28 ) with tegumen evenly curved in dorsal part, uncus not differentiated, socii present but weak; lower edge of sacculus angled, narrow portion of valva long and curved, cucullus large, broad, subcircular with a rounded-rectangular ventral angle; aedeagus ( Fig. 28 View FIGURES 23 – 28 ) with basal 1/5 broader and straight, otherwise slender, evenly curved; with 9 cornuti of different length, from large spindle-shaped to very small; 10 carinae.

Female. Head, Thorax: Similar to male, but blackish suffusion on basal 2/3 of forewing upperside less heavy. Labial palpus 2.0 times diameter of eye, legs paler. Abdomen: Female genitalia ( Fig. 36 View FIGURES 36 – 40 ) with both pairs of apophyses long; posterior edge of sternite 7 with deep round excavation, anterior edge strongly sclerotised and with two pairs of humps; lamella postvaginalis long, broadened posteriorly; ostium cylindrical, ventral margin deeply concave; ductus bursae gradually widened towards corpus bursae, sclerotised in medial part; ductus seminalis inserted into ductus bursae just before corpus bursae; corpus bursae with two curved, horn-shaped signa with small bases.

Diagnosis. This species is externally similar to M. kingstoni from which it differs by its larger size and the presence of a distinct white spot posteriorly on the thorax. In the male genitalia, the broad, nearly subcircular cucullus is characteristic of M. purana . In the female, the deeply excavated posterior edge of sternite 7 and the long lamella postvaginalis are very different from other known Multiquaestia females.

Distribution. Tanzania.

Etymology. The species name refers to the uniformly coloured markings of the forewing, in contrast to M. iringana n. sp. from the same locality, which has a more blurred forewing pattern.
