Baccha mima Hull, 1949  — Hull, 1949 a: 188. Type locality: Peru. Holotype female CNCAbout CNC. Ocyptamus mimus  . Thompson et al., 1976: 22 (catalog citation).

Male. Male unknown.

Female. Head: Black. Tubercle large and without pollen. Lunule almost entirely black, with small pale regions above antennal insertions. Frons with central spot of brown dull pollen, shining white pollen laterally, connected to pollen from face and expanding medially as triangular maculae dorsal to central spot, dorsal ⅓ without pollen; frontal prominence bare and with no pollen. Antennal insertions confluent. Vertex with a single median row of pile; ocellar triangle ~ 2 times its length from posterior eye margin, and ~ 1 occellus-width from lateral eye margin. Dorsal ⅓ of occiput with 2 rows of simple black pile, anterior row very short, middle 2 / 4 with 1–2 anterior rows of simple black pile, posterior row with much longer, scale-like white pile; ventral ¼ with 2–3 rows of scale-like white pile, anterior rows shorter.

Thorax: Black. Scutum mainly with sparse white pollen and a central pair of dull brown pollinose vittae; scutum mostly with very short black pile, except notopleuron white pilose; anterior row of shining white pile not so distinct and largely interrupted in the middle. Scutellum black, with very short black pile, subscutellar fringe pile very short and black. Pleuron black, except metaepisternum and metaepimerum pale; pleuron white pilose. Calypter yellow, dorsal lobe with normal fringe. Plumula short and yellow. Halter yellow.

Wing: Basal ½ light brown (brown on cells bc, c, sc, r, basal ½ of r 1, basal 1 / 5 of r 2 + 3, base of r 4 + 5, bm, basal 1 / 6 of dm, cu p, basal ¼ of cua 1 and the anal lobe), entirely microtrichose; alula normal, basally 1.4 times to apically 3 times as broad as c cell, light brown, entirely microtrichose.

Legs: All legs mainly pale, all tarsi black, pile white to yellow on pale regions. Profemur with subapical light brown macula. Mesofemur with subapical light brown macula; black pile sparse on mesofemur but concentrated on lateral row on apical ⅔. Subapical ⅓ of metafemur and most of metatibia dark brown, metatibia pale on base and apex; pile black on lateral ½ of metacoxa.

Abdomen: Greatly elongated, 4.6 times as long as thorax; 2 nd to 4 th abdominal tergites of similar lengths but narrowing towards apex; dark brown. First tergite pale on lateral 1 / 6, and white pilose, except for a few black pile basodorsally, pile longer on baso-ventral ½ and becoming very short towards middle. Second tergite rectangular, very long, length 2.6 times minimum width, pale on baso-lateral ¾, and with very short black pile. Third tergite long, length 3.8 times minimum width, pale on baso-lateral ⅓, and with very short black pile. Fourth tergite long, length 2.8 times minimum width, and with very short black pile. Fifth tergite rectangular, length 1.4 times minimum width, and fused to sternite on apical ¾. Sixth segment whole, laterally compressed, ⅓ of the length of the 5 th. Genitalia: Not dissected.

Length. 11.5mm; wing 6.5mm.

Distribution. Peru (Ucayali).
