( Figs 28, 31, 34 View FIGURES 28–36 )

Type material. Holotype, female: Ecuador: Napo prov., Tiputini biodiversity station, 220–250 m, October 1998, 00° 37’55’’S, 76° 08’39’’W, T.L. Erwin et al collectors GoogleMaps . Allotype, male: same data as HT. Paratypes: same data as HT (3) GoogleMaps ; same data as HT except February 1999 (2) GoogleMaps ; Orellana prov., Estacion Cientifica Yasuni PUCE, GIS: -0.674, -76.398, ex Cecropia pet., #628, 7ii2018, R. Osborn, leg. GoogleMaps (2). Holotype, allotype and one paratype temporarily held in trust at USNM for MECN, and two paratypes each in MSUC, QCAZ and ZMBN .

Diagnosis. Interstriae 10 sharply elevated to near apex. Protibiae without additional mesal tooth. Distinguished from species similar to S. chapuisi and S. inordinatus by the much larger punctures on the pronotum, particularly near the anterior margin, and to a lesser degree the finely rugose appearance of the elytra.

Description female. Length 1.7–1.9 mm, 2.2–2.4 × as long as wide; colour dark brown. Head. Eyes entire, separated above by 2.3–2.6 × their width. Frons flattened, smooth and shiny in glabrous central area; vestiture consisting of long slick setae arising from vertex, reaching epistoma. Antennal club pilose, without sutures. Funiculus 6-segmented. Pronotum reticulated, dull, with distinct, deep, dense punctures spaced by 1 × their diameter, reaching anterior margin. Vestiture consisting of 4 erect, very long setae (2-0-2). Elytra lightly rugose, shiny; striae regular, weakly impressed, punctures medium large, spaced by 1–2 × their diameter; interstriae 2–3 × wider than striae, punctures as in striae, mainly in rows; interstriae 10 sharply elevated to near apex. Glabrous. Legs. Procoxae separated by 0.2–0.4 × the width of one procoxa. Mesocoxae separated by 0.6–0.8 × the width of a procoxa. Protibiae narrow, distal tooth 2 slightly longer than 1, with 3–4 sharp transverse rugae towards tibial base; protibial mucro short. Meso- and metatibiae long and narrow, with 6–8 lateral socketed teeth on distal two-thirds and half, respectively. Ventral vestiture. Setae metanepisternum and metasternum simple, on mesanepisternum bifid.

Male. Similar to female except frons convex, lightly impressed just above epistoma, strongly reticulated, with scattered punctures; vestiture consisting of a few scattered setae.

Key ( Wood 2007). Keys to couplet 55 and 56, near S. chapuisi , but has much larger punctures on the pronotum and elytra.

Etymology. The Latin name cancellatus is a passive participle of cancello, meaning latticed, referring to the densely reticulated pronotum which is not shining.

Biology and distribution. Known from two lowland Ecuadorian Amazon localities. It was collected from Cecropia petioles at low altitude and from four different fogging samples.
