Figs. 6, 28, 256–266
Leptocera (Coprophila) setulosa Duda, 1929: 38 [both sexes]. Type locality: Bolivia, 60 km N San José de Chiquitos. STs, both sexes (SMNS).
Description. Body length 1.3–2.1 mm. Body light brown to brown. Face light brown, frons brown. Interfrontals in 4 subequal pairs, postocellar bristles slightly convergent, 1 pair of small postocellar setulae. Eye to gena ratio approximately 2.5:1; 10–15 small genal setae present, anterior seta approximately 1.5 times as long as posterior setae.
Scutum with 3 additional pairs of dorsocentral bristles anterior to prescutellar pair, each approximately 1/3 as long as prescutellar bristles. Scutellum with 25–35 discal setae between basal 1/5 and basal 1/2, row of 4 or more bristles at 1/2 approximately 5 times longer than other discal setae; 4 lateral bristles between larger anterior and posterior marginal scutellar bristles, second lateral bristle long, approximately 2/3 as long as anterior marginal bristle. Katepisternum with 2 long subequal dorsal bristles, anterior bristle extending to just beneath wing base, posterior bristle extending just beyond wing base. Legs and fore coxa brown to light brown. Mid tibia with additional small anterodorsal bristle at 1/5 with paired posterodorsal bristle, and strong proximal posterodorsal bristles at 1/3 and 1/2. Mid basitarsus with stout anterior setae at 1/2 and subapical, a strong sub-basal posteroventral bristle approximately 3 times width of mid basitarsus in length, an equally long anteroventral bristle at 1/2, and a small posteroventral bristle at 1/2. Second costal sector 0.7–1.0 times as long as third costal sector. Costal bypass long, extending 7 or more vein widths beyond R 4+5. Anal vein with distinct angulate bend.
Male terminalia: Sternite 5 rounded rectangular, with posteromedial patch of microtrichia; lateral bristles slightly enlarged. Sternite 6 straight medially. Epandrium with enlarged pair of dorsolateral and ventrolateral bristles; subanal plate present, narrow; cercus 1 enlarged central bristle, ventral margin rounded. Surstylus with rounded posterior and ventral lobes, and row of stout ventral bristles. Postgonites straight, relatively broad, blunt at apex. Basiphallus gently curved, tubular, open posteriorly dorsal to epiphallus; epiphallus with blunt, elongate crest. Lateral sclerites of distiphallus with 2 dorsal processes, dorsal margin deflected medially, apex rounded, with several small spines; central sclerite fused with lateral sclerites ventral to second process. Membranes elongate, narrow, with apical spines.
Female terminalia: Tergite 8 reduced to long lateral sclerites, connected by a dorsal membrane. Tergite 10 and cerci dorsally flattened; Tergite 10 glabrous, orange, central bristles minute, fused to cerci posterolaterally and tightly associated medially; cerci orange, glabrous anteriorly, pollinose posteriorly, cercal bristles short and straight, apical bristle modified into a stout spine. Sternite 7 broad, short, and concave posteriorly. Sternite 8 with slightly pointed anterior margin, concave posterior margin, with anterior and posterior rows of 4 small bristles bordering a pair of larger bristles. Posterior margin of sternite 10 curved dorsally. Spermathecae spherical; duct length approximately 2 times as long as spermathecal bulb.

Comments. Coproica setulosa is characterized by four pairs of dorsocentral bristles and exceptionally elongate anterior and posterior katepisternal bristles (Fig. 18). The original description of C. setulosa (Duda 1929) refers to numerous elongate dorsocentral bristles (a unique character in Coproica) along with a characteristic elongate chaetotaxy. The type series for C. setulosa was not examined as its identity is easily confirmed by the description.
