Type material. Holotype, male: Ecuador: Napo province, Cosanga, Yanayacu Station , 2100m, GIS: -00.594, - 77.877, bottle trap, #766, 1iii2018, R. Osborn, leg. GoogleMaps Allotype, female: same data as HT. Both types are deposited in QCAZ GoogleMaps .

Diagnosis. Interstriae 10 elevated to level of metacoxae. Protibiae with a rather large additional mesal tooth near tarsal insertion. Body setose, with particularly long interstrial setae. Distinguished from S. constrictus Wood, 1977 by the regular (vs. twisted) shape of the protibiae with tooth 1 and 2 subequal in size, by the shorter interstrial setae, and by the simple setae on metanepisternum.

Description, male. Length 2.3 mm, 2.4 × as long as wide; colour black. Head. Eyes entire, separated above by 2.5 × their width. Frons convex, epistomal margin oblique from lobe towards antennal insertion, a low, median, longitudinal keel running from epistoma to the middle of the frons, surface strongly reticulated, with coarse punctures from epistoma to vertex; vestiture consisting of scant, short setae on lower frons. Antennal club with segments 1 and 2 subcorneous, two procurved sutures marked by setae. Funiculus 5-segmented. Pronotum strongly reticulated, with dense, deep punctures on posterior half, spaced by their diameter, on anterior half replaced by low, granulate asperities. Vestiture consisting of very fine, long, setae (0-0-0). Elytra smooth, shiny; striae regular, lightly impressed, punctures deep, spaced by their diameter; interstrial punctures smaller, more widely spaced, in regular rows except very densely spaced and strongly confused along suture; interstriae 10 elevated to level of metacoxae. Vestiture consisting of fine, slightly curved, interstrial and strial setae, increasing in length on declivity, those on interstriae twice as long as strial setae. Legs. Procoxae separated by 0.5 × the width of one procoxa. Mesocoxae separated by 1.0 × the width of a procoxa. Protibiae broader towards apex, distal tooth 1 and 2 of equal size, with 5 additional small granules along the edge towards tibial base; a rather large additional mesal tooth present near the tarsal insertion; protibial mucro curved posteriorly. Meso- and metatibiae with 6–7 lateral socketed teeth on distal half and third, respectively. Ventral vestiture. Setae on mesanepisternum trifid, on metasternum and metanepisternum simple.

Female. Identical to male except 2.6 mm long, 2.6 × as long as wide, eyes separated above by 2.9 × its width, frons flat, smooth and shiny, pronotum punctured to anterior margin without asperities.

Key ( Wood 2007). The male will key to couplet 113, near S. libidus Wood, 1978 View in CoL , but the new species has much longer interstrial setae and should key to couplet 115, S. constrictus View in CoL . The female, which has no asperities on pronotum, will be keyed to couplet 60 with no further match.

Etymology. The Latin name criniger is a masculine nominative adjective, meaning long-haired, referring to the very long interstrial setae on the elytra.

Biology and distribution. Only known from the type locality at high altitude in Ecuador .
