Description.

Female. Head, vertex with six setae between the eyes and four near the anterior margin. Eyes with two facets on pigmented base. Thorax ( Figs 1, 2 ) much wider than long. Posterior margin of mesonotum with medial dorsal process. Ten to 12 notopleural setae. Each thoracic ctenidium with about 23 spines. Tibiae scalpel­shaped with three ventrodistal rows of setae. Sternal plate wider than long. Abdomen, tergite I wider than long with 4–6 setae (normally six), on each side of posterior margin. Tergite II divided longitudinally; each half ending as a narrow lobe (about two times longer than wide), each lobe with 2–3 long and 3–6 short spine­like setae. Anal segment with lateral margin parallel, 14–19 setae on each side. Lateral connexivum with long pustulate setae ( Figs 1, 2 , 5 ). Sternite II wider than long, ctenidium with about 72 spines. Sternite V divided into two eliptical sclerites, each with 9–10 marginal setae. Sternite VI entire with 14–20 discal setae and 16–20 setae on posterior margin. Genital plate forming three rounded plates; a narrow medial plate with two setae, and wide lateral plates each with four setae ( Fig. 6 ). Anal sclerite rounded and long with two setae. Adanal plates irregularly shaped, each with about four setae ( Fig. 6 ).

Male. As in female except as follows (Figs. 34). Head, vertex with four setae between the eyes. Thorax, nine notopleural setae. Abdomen, sternite V with two rows of four and eight spine­like setae ( Fig. 4 ). Aedeagus small and parallel­sided, dorsal margin serrated with two basal setae. Phallobase with one seta. Postgonites with rounded base, pointed apical end bearing three patches of five, four, and four setae, respectively ( Fig. 7 ). Type material. Holotype, female (MZSP 900851) from Eptesicus brasiliensis (MZSP 27736), BRAZIL: São Paulo: Cananéia, Ilha do Cardoso (25 05'S, 47 59'W), 16/XII/ 1990, S. Fazzolari­Corrêa leg. Paratypes, 1 male and 6 females (MZSP 920050), same host species (MZSP 28355) and data as holotype except S. Fazzolari­Corrêa and P.E. Vanzolini leg.

Etymology. The specific epithet gives homage to mammalogist Juliana Quadros for her courtesy, and cooperation with our studies of bat flies.
