Type material. Holotype, female: Ecuador: El Cotopaxi, La Maná, Yakusinchi Reserve , S 00°07.030’ W 79°08.717’, 500m, 3.3.2017, ex Cecropia, Osborn, Bateman & Martinez . Allotype, male: same data as holotype. Paratypes: same data as holotype (1 male, 2 females) . Holotype and allotype in QCAZ , one paratype each in ZMBN, USNM and MSUC .

Diagnosis. Interstriae 10 sharply elevated to near apex. Protibiae without additional mesal tooth. Elytra glabrous. Distinguished from related species in the cecropiavorus and piceus groups by the rigid and protruding tuft of setae in the female frons and the faint asperities on the pronotum.

Description female. Length 1.7–1.8 mm, 2.3–2.4 × as long as wide; colour dark brown to black. Head. Eyes entire, separated above by 2.0–2.2 × their width. Frons weakly impressed on lower two-thirds; surface densely punctured in flattened area. Vestiture consisting of rather few, long, coarse setae directed forward, arising from just below upper level of eyes to epistoma. Antennal club pilose, without clear sutures. Funiculus 6-segmented. Pronotum weakly reticulated, subshining, punctures on posterior two-thirds small, shallow, spaced by 2–3 × their diameter, replaced on anterior one-third by fine asperities. Vestiture consisting of 6 erect setae (4-0-2). Elytra smooth, shiny; striae regular, not impressed, punctures spaced by 1–2 × their diameter; interstriae 2–3 × wider than striae, punctures similar to those in striae; interstriae 10 sharply elevated to near apex. Glabrous. Legs. Procoxae separated by 0.3 × the width of a coxa. Mesocoxae separated by 0.8 × the width of one procoxa. Protibiae narrow, distal tooth 1 and 2 subequal, 3–4 additional smaller, blunt, lateral spines decreasing in size towards tibial base; protibial mucro obtuse. Meso- and metatibiae with 7–8 lateral socketed teeth on distal two-thirds. Ventral vestiture. Setae on mesanepisternum bifid, on metanepisternum and metasternum simple.

Male. Similar to female except slightly smaller (1.5–1.7 mm long), frons convex; surface finely reticulated, lightly punctured; vestiture consisting of short, scattered setae mainly on and near the epistomal lobe.

Key ( Wood 2007). Does not fit any species following couplet 36; a better fit with species following couplet 50, but the female frons has no shiny area and the vestiture does not reach the upper level of eyes.

Etymology. The species is named after Jane Sloan in recognition for her long-term efforts in protecting the Yakusinchi forest reserve.

Biology and distribution. Only known from the type locality in lowland rainforest. Specimens were taken from Cecropia leafstalks.
