Type material. Holotype, female: Ecuador: El Cotopaxi, La Maná, Yakusinchi Reserve , S 00°07.030’ W 79°08.717’, 450–550m, 12–14.V.2015, Cognato, Smith, Osborn, Martinez et al; Sample EC 12, ex Cecropia petioles without urticating hairs . Allotype and Paratypes: same label as holotype (2 males, 1 female). Holotype and allotype in QCAZ , one paratype each in USNM, ZMBN , and MSUC.

Diagnosis. Protibiae very broad with laterally curved mucro, without additional mesal tooth; interstriae 10 sharply elevated to near apex. Distinguished from species in the atratus group by having setae only on odd interstriae and the procoxae are less widely separated.

Description female. Length 1.8–2.0 mm, 2.3–2.4 × as long as wide; colour black. Head. Eyes sinuate, separated above by 3.0–3.3 × their width. Frons weakly impressed from just below upper level of eyes to near epistoma, surface densely punctured except for an impunctate weakly elevated longitudinal callus on lower third about onefifth the width of impressed area. Vestiture consisting of fine, short setae in punctured area. Antennal club with two obliquely procurved sutures marked by long, fine setae; first two segments corneous, dark brown. Funiculus 6-segmented, segments 4–6 gradually broader. Submentum and area around strongly and obliquely impressed, with long setae. Pronotum weakly reticulate, subshining, with distinct punctures on posterior half spaced on average by 1–2 × times their diameter, faint asperities on anterior fourth. Vestiture consisting of 8 erect setae (4-2-2). Elytra smooth, shiny; striae regular, lightly impressed, deep punctures spaced by their diameter; interstriae 3–4 × wider than striae, punctures tiny, shallow, in rows; interstriae 10 sharply elevated to near apex. Vestiture consisting of fine, widely spaced, erect setae on odd interstriae. Legs. Procoxae separated by 0.5–0.6 times the width of a coxa. Mesocoxae separated by 0.8–0.9 × the width of one procoxa. Protibiae broad, distal tooth 2 extending beyond tooth 1, 3–4 additional smaller, sharp, lateral spines decreasing in size towards tibial base; protibial mucro long, curved laterally. Meso- and metatibiae with 6–8 lateral socketed teeth on distal two-thirds and half, respectively. Ventral vestiture. Setae on mesanepisternum finely plumose, on metanepisternum simple.

Male. Similar to female except frons convex, just above epistoma lightly impressed in a V-shaped formation that forms an acute triangular keel; surface reticulated, lightly punctured; vestiture consisting of short, densely placed setae on the epistomal lobe, scattered elsewhere; pronotum more strongly asperate on anterior fourth, anterior margin lightly serrated.

Key ( Wood 2007). Conflicts with couplet 2 due to the broad protibiae, and punctures not reaching anterior margin of the pronotum. Also conflicts with choices in couplet 12 (frontal carinae and vestiture).

Etymology. The Latin name latipes is a gender neutral, nominative adjective, meaning wide-legged (latus =wide, pes =foot), referring to the very broad protibiae in this species.

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