( Figs 30, 33, 36 )

Type material. Holotype, female: Ecuador: Napo province, Cosanga, Yanayacu station , 2100m, GIS: -0.594, - 77.877, in FIT ‘Petrov’, #818, 24ii2018, R. Osborn, leg. Holotype in QCAZ .

Diagnosis. Interstriae 10 sharply elevated to near apex. Protibiae without additional mesal tooth. Distinguished from S. chapuisi , S. lubricus and related species by the thick tuft of setae in the female frons.

Description female. Length 2.4 mm, 2.2 × as long as wide; holotype bicoloured with dark brown on most of pronotum and lateral patches on elytra, while light brown elsewhere. Head. Eyes entire, slightly protruding, separated above by 3.2 × their width. Frons presumably flattened, completely covered by a dense, long tuft of golden setae, arising broadly on vertex, reaching epistomal lobe. Antennal club pilose, without sutures. Funiculus 6-segmented. Pronotum reticulated, dull, with tiny, shallow punctures spaced by 1–2 × their diameter, barely reaching anterior margin. Vestiture consisting of 6 erect, very long setae (4-0-2). Elytra smooth, shiny; striae regular, not impressed, punctures shallow, small, spaced by 1–2 × their diameter; interstriae 3–4 × wider than striae, punctures much smaller than in striae, strongly confused; interstriae 10 sharply elevated to near apex. Glabrous. Legs. Procoxae separated by 0.4 × the width of one procoxa. Mesocoxae separated by 0.9 × the width of a procoxa. Protibiae narrow, distal tooth 2 slightly longer than 1, with 2–3 small, transverse rugae towards tibial base; protibial mucro nearly obtuse. Meso- and metatibiae with 7 lateral socketed teeth on distal half and one-third, respectively. 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, larger size, and very dense tuft of setae in the female frons.

Etymology. The Latin name jubatus , an alternative form of iubatus, is a masculine nominative adjective, meaning maned or crested, referring to the dense, long tuft of setae in the female frons.

Biology and distribution. Only known from the type locality in Ecuador. It was sampled in a flight intercept trap baited with ethanol at high altitude together with S. comosus .
