Type material. Holotype, female: Ecuador: Napo province, road to Cosanga , 2100m, GIS: -0.594, -77.877, ex Cecropia petiole, #645, 17ii2018, R. Osborn, leg. Allotype and Paratype (1): Napo province, Cosanga, McClarin’s camp, 2100m, GIS: -0.594, -77.877, ex Cecropia petiole, #646, 17ii2018 . Holotype and allotype in QCAZ, 1 paratype in MSUC.

Diagnosis. Interstriae 10 sharply elevated to near apex. Protibiae without additional mesal tooth. Distinguished from the very similar S. projectus by the slick setae in the female frons, and from S. speculofrons by the broadly rounded anterior margin of the pronotum and by the longer setae in the female frons.

Description female. Length 2.6–2.9 mm, 2.2–2.4 × as long as wide; colour dark brown. Head. Eyes entire, separated above by 2.7–3.0 × their width. Frons flattened, smooth, shiny, slightly impressed and punctate in a narrow horse-shoe shaped area from level of antennal insertion to vertex; vestiture consisting of long slick setae in impressed area. Antennal club pilose, without sutures. Funiculus 6-segmented. Pronotum reticulated, dull, with tiny, shallow punctures spaced by 1–2 × their diameter, reaching anterior margin. Vestiture consisting of 6 erect, very long setae (4-0-2). Elytra smooth, shiny; striae regular, weakly or not impressed, punctures shallow, small, spaced by 1–2 × their diameter; interstriae 3–5 × wider than striae, punctures smaller than in striae, strongly confused; interstriae 10 sharply elevated to near apex. Glabrous. Legs. Procoxae separated by 0.2–0.4 × the width of one procoxa. Mesocoxae separated by 0.8 × the width of a procoxa. Protibiae very narrow, distal tooth 2 longer than 1, with 3–4 sharp transverse rugae towards tibial base; protibial mucro nearly obtuse. Meso- and metatibiae long and narrow, with 7–8 lateral socketed teeth on distal half. Ventral vestiture. Setae on mesanepisternum, metanepisternum and metasternum simple.

Male. Not known.

Key ( Wood 2007). Keys to couplet 55 and 56, near S. chapuisi , but has strongly confused interstrial punctures, and much larger size.

Etymology. The Latin name lubricus is a nominative masculine adjective meaning slick and smooth, referring to the slick golden setae in the female frons.

Biology and distribution. Only known from the high-altitude type locality in Ecuador. It was collected from Cecropia petioles together with S. projectus , S. grandis (Schedl, 1962) , S. inordinatus Jordal and Smith (described below), and S. comosus Jordal and Kirkendall, 2019 .
