Type material. Holotype, female: " Ecuador, Pichincha, Palmeras 1900 m, 21 Jan 1989, D. Lombeida". Allotype male: " Ecuador: Pichincha Prov. El Pahuma Orchid Reserve, S00º 01.497' W78º37.942', 1900–2200 m, 28v–2vi 2011, S.M. Smith" (handwritten underside of label: "in flight"). Paratypes: same label as holotype (10); same label as holotype except " 22. Jan 1989, P. Zamboni" (5) and “ 22. Jan 1988, P. Zamboni” (8). Holotype, allotype and 19 paratypes deposited in QCAZ, other paratypes in ZMBN (2), USNM (2), and MSUC (2).
Diagnosis. Interstriae 10 sharply elevated far beyond level of metacoxae, protibiae without an additional inner tooth. Unmistaken by the female frons containing two setose grooves close to epistoma that reminds about a pigs face, and by the densely setose scapus. Related to S. alni Wood, but distinguished by the near glabrous female frons (S. alni with long golden tuft of setae from vertex to epistoma) and by the long setae along the entire length of the scapus.
Description female. Length 2.4–2.8 mm, 2.2–2.3 times longer than wide; colour mainly black, brown on basal third of pronotum and legs. Head. Eyes separated above by 2.3–2.4 times their width. Frons convex, with two longitudinal deep grooves from epistoma to level of antennal insertion, grooves broadest close to epistoma; surface generally impunctate, smooth and shiny, a few tiny punctures on upper half and vertex. Vestiture consisting of short setae mainly confined to grooves. Antennal club pilose, without sutures. Funiculus 6-segmented, last segment visible but integrated with club. Scapus with long setae along its entire length. Pronotum as long as wide, widest at base, sides straight, broadly rounded in front; surface reticulated, dull, punctures small and shallow, spaced by 1–2 times their diameter, replaced on anterior third by very fine, low asperities. Glabrous, except 6 erect longer bristlelike setae (4–0–2). Elytra 1.3–1.4 times longer than wide, 1.5 times longer than pronotum; sides slightly curved, broadest at mid-length, fairly broadly rounded behind; striae not impressed, punctures small, shallow but distinct, spaced by the diameter of a puncture; interstriae 4 times wider than striae, punctures about two-third the size of a strial puncture, confused, surface reflecting a mosaic pattern of irregularly shaped cells around each puncture. Interstriae 10 reaching level of last ventrite. Vestiture consisting of microscopic setae in strial and interstrial punctures. Legs. Procoxae separated by one third the width of a coxa. Mesocoxae separated by the width of one procoxa. Protibiae very narrow, lateral teeth 1 and 2 of equal size, 2–4 additionally small lateral spines towards the base of tibia. Meso- and metatibiae with 6–7 lateral socketed teeth on distal half. Ventral vestiture. Setae on mesanepisternum and metanepisternum simple.
Description male. Similar to female except grooves in frons are more shallow and shorter, with few setae.
Key. From couplet 23 there is a generally poor match with the character states listed.
Etymology. From Latin sus, meaning ‘pig’, referring to the frons of this species that resembles a pig’s face.
Biology and distribution. Known from two high altitude localities in the Ecuador province of Pichincha. One specimen was collected at flight, collection details of other specimens not known. The collection of longer series at two different dates indicates that the species is locally fairly common.
