Multiquaestia iringana Aarvik & Karisch View in CoL , new species
( Figs. 1, 3, 5, 6 View FIGURES 1 – 6 , 12 View FIGURES 7 – 14 , 29 View FIGURES 29 – 35 , 30, 37 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 2723 L. Aarvik ( NHMO). Paratypes: 43, 2Ƥ, same data as holotype, male and female paratypes with genitalia on slides 2740 and 2739 L. Aarvik, respectively (3 paratypes LAA; 3 NHMO).
Description. Adult. Male ( Fig. 12 View FIGURES 7 – 14 ). Wingspan 13.5–16.0 mm. Head ( Fig. 1 View FIGURES 1 – 6 ): Greyish white. Antenna light brown, scape greyish white. Labial palpus 2 times diameter of eye, externally dark grey, internally greyish white; due to scaling of second segment triangular in lateral view. Thorax: Light grey, becoming white just beyond middle; tegulae light brown. Legs brownish grey, hindleg paler and more yellowish, tarsi with paler rings. Forewing upperside with basal 2/3 brown, heavy blackish suffusion forming large triangle in costal half; terminal 1/3 pale ochreous; on dorsum two speckled white marks reaching to about 1/3 from costa; a white dot present somewhat beyond distal white mark, and one between wing base and inner white mark; there is blackish suffusion between the two white marks and sub-basally on dorsum; the white marks are speckled with dark dots, more so than in other species of the genus; a few dark scales present in terminal area.
Hind wing upperside dark brownish grey, slightly dappled in distal half; ochreous hair-pencil from base of posterior margin to scale cover on dorsum of abdomen. Abdomen: Grey, abdominal brush grey above, otherwise pale ochreous. Male genitalia ( Fig. 29 View FIGURES 29 – 35 ) with tegumen evenly curved in dorsal part, uncus not differentiated, socii present but weak; lower edge of sacculus angled twice, cucullus neck very short, cucullus large, broad, rounded along dorsal and distal edge, ventral angle produced into distally rounded point; aedeagus ( Fig. 30 View FIGURES 29 – 35 ) basally broader, otherwise slender, narrowest in middle and slightly widened distally, strongly and evenly curved; with 12 cornuti, and about 15 carinae.
Female. Head, Thorax: Similar to male, but lacking large blackish triangle on costa of forewing upperside, replaced by wavy dark brown shades; speckled white marks on dorsum surrounded by more blackish suffusion than in male; legs paler. Abdomen: Female genitalia ( Figs. 37 View FIGURES 36 – 40 ) with posterior edge of sternite 7 with shallow excavation, anterior edge strongly sclerotised and with two humps; lamella postvaginalis large, broadened laterally; ostium plate-shaped; ductus bursae with coil, the whole length sclerotised, but more strongly in posterior part; corpus bursae with two curved, horn-shaped signa with large bases.
Diagnosis. M. iringana is sympatric with M. purana from which it differs by its less contrasting wing pattern. In the forewing the pale terminal area and the white triangles are more speckled than in other Multiquaestia species. The male genitalia are most similar to those of M. purana , but they differ by a narrow and much shorter valva neck and a more acutely angled ventral corner of the cucullus. The female genitalia resemble those of M. albimaculana Karisch , but in that species the coil in the ductus bursae is situated closer to the ostium, and the anterior edge of sternite 7 lacks humps.
Distribution. Tanzania.
Etymology. The species is named after the region Iringa in Tanzania where the type series was collected.
