content: Holotype female. - Length 12.4 mm. Frons slightly divergent below, index 6, yellowish gray tomentose below, blackish gray above; frontal callus narrow, relatively short, gradually tapered to point less than half way to vertex; subcallus yellowish gray tomentose, frontoclypeus light brownish gray tomentose; genae gray tomentose, pale yellowish pilose; beard pale yellow; scape and pedicel of antennae reddish gray tomentose; basal flagellomere reddish basally, darkening apically dorsobasal margin with short, sharp projection; apical flagellomeres black; apical palpomere of maxdlary palpi long and slender, dark brown, black pilose except for bare central area on exterior surface, elongate and slender, rounded apically; eyes (relaxed) without pattern. Mesoscutum dark brown, with conspicuous gray tomentose sublateral and diffuse lateral stripes, sublaterals broad anteriorly, narrowed behind transverse suture and joining broad crescent-shaped pale spots anterior to scutellum, bearing mixed black and yellowish hairs; scutellum dark brown with gray lateral margins; notopleural lobes dark brown, contrasting with gray tomentose marginal stripes; pleurae gray tomentose, white pilose, slightly darkened ventrally on anepisternum and anepimeron; coxae concolorous with pleurae; femora, tibiae and tarsi deep black. black pilose; wings distinctly smoky in distal half, costal cell yellow-brown. cells br, bm and basal half of cu distinctly paler. Abdomen brown and black, with distinct pale tomentose and pilose hind margins on tergites 2-4, tergites 5 - 7 narrowly paler apically but lacking pale hairs; tergite 1 pale brown with 2 large submedian and small lateral translucent pale spots; tergite 2 brown with large black median spot; tergites 3 and 4 with median and lateral black spots; tergites 5-7 black except for narrow paler hind margins; sternite 1 pale yellowish with median dark haired spot; sternite 2 yellowish only along lateral margin, remainder of sternum dark grayish tomentosc and black pilose except scattered yellowish hairs along posterior margin of sternite 2 and 3. Male. - More reddish brown than female; maxillary palpi pale yellow, apical palpomere slender, scarcely enlarged apically, black pilose; beard bright yellow; eyes with upper facets not noticeably differentiated from lower facets; mesoscutum with sublateral and lateral stripes yellowish brown tomentose, yellow pilose; abdominal pattern similar to female except more extensively yellowish brown, and median black spot on tergites 3 and 4 evanescent, abdominal dorsum bearing bright golden and black hairs. Type Data. - Holotype female. MADAGASCAR: Prov. Fianarantsoa, 7 km W. of Ranomafana, 900 m, 17 - 22 February 1990, Coll. W. E. Steiner, malaise trap in small clearing, montane rainforest. Paratypes. 3 females, same data as holotype; 18 - 20 January, 1 male; 20-31 January, 12 females, 2 males: 1-9 February, 8 females: 1-7 March. 5 females: 8-13 March. 5 females; 20-24 March 1990, 1 female. Length of paratypes is 10 - 13.2 mm. There is considerable variation in the extent of the sublateral and lateral pale stripes on the mesoscutum of the paratype series. In some specimens, the sublateral stripes are rather narrow and incomplete, with the dark brown intervening areas extensive; in other specimens, the sublateral stripes are broadly confluent with the lateral stripes, and the dark brown intervening area is reduced. The color of tergites 3 and 4 varies considerably from mostly black, obliterating the median and lateral dark spots, to brown medianly with the median spot evanescent. In addition, some specimcns have the basal flagellomere entirely reddish, contrasting with the black apical flagellomeres, the apical palpomere varies from light to dark brown, and the frontal callus is longer, extending about 2/3 the length of the frons. A. chaineyi is close to Aegophagamyia (T.) notata (Surcouf) in its general appearance, but differs in being much smaller, with a shorter, stouter basal flagellomere, dark brown apical palpomere, abdominal tergum 1 mostly pale, and tergum 2 with a black median spot only, lateral spots absent. The male differs in being much smaller. and having the beard, pleural hairs, mesoscutal hairs and pale hairs on the abdomen bright golden yellow.
