( Figs 55, 58, 61 )

Type material. Holotype: Colombia, Cundinamarca, P. & B. Wygodzinky. Road Bogota to Choachi, 3250¯3000 meters, July 19, 1967 . Holotype deposited in AMNH .

Diagnosis. Interstriae 10 obscurely elevated to the level of metacoxa; protibiae with a sharp additional mesal tooth just inside the lateral margin between tooth 1 and 2; tooth 2 socketed. Strial punctures on elytra confused, volcano shaped; interstriae not clearly marked, cuticle wrinkled. Distinguished from all species with similarly granulated pronotum by the much longer interstrial setae (except Scolytodes opacus Wood , which has impressed striae 1 and tuberculate interstriae 1¯3 on posterior half of elytra), and by the much larger size (except Scolytodes major (Eggers) , which has short elytral setae and smooth cuticle).

Description, female? Length 4.1 mm, 2.1 × longer than wide; colour black. Head. Eyes entire, slightly bulging, separated above by 3.1 × their width. Frons flattened, smooth with small punctures, strongly reticulated, a low carina run from each lateral edge of the epistoma towards the anterior margin of the eyes near antennal insertion; vestiture consisting of scattered fine setae. Antennal club with two triangularly procurved sutures marked by dense short setae. Funiculus 6-segmented. Pronotum strongly reticulated, dull; punctures small, volcano shaped, reaching anterior margin, puncture on anterior two-thirds associated with low, shiny, crescent shaped asperities. Vestiture consisting of long, fine setae in no particular pattern (0–0–0). Elytra sub-shining, surface wrinkled, strial and interstrial punctures of variable size, confused, volcano shaped. Vestiture consisting of interstrial rows of erect, long, fine setae, and intermixed strial and interstrial setae about one-third as long. Legs. Procoxae separated by 0.5 × and mesocoxae 1.2 × the width of one procoxa. Protibiae broad on distal half, distal teeth 1 and 2 of equal length, tooth 2 with socketed denticle exposed, 4¯5 additional small spines towards base; protibial mucro large, curved posteriorly. Mesotibiae with 10 lateral, socketed teeth on distal two-thirds, metatibiae with 10¯11 teeth on distal half. Ventral vestiture. Setae on ventrites, metasternum and metanepisternum long, simple.

Key ( Wood 2007). Keys to couplet 123, S. opacus , but stria 1 is not impressed on declivity, interstriae are without tubercles, and size is much larger.

Etymology. The species name is composed by longi, a Latin masculine adjective in its genitive form, meaning extended or prolonged, and pilus, a Latin masculine noun, meaning hair. The name refer to the exceedingly long interstrial setae on the elytra, with shorter setae mixed in between

Biology and distribution. This species is only known from the high altitude type locality in Colombia
