( Figs 20, 23, 26 )

Type material. Holotype, female: Panama, Canal Zone, Albrook forest site, Fort Clayton. Lot No. 177, March 7/ 8, 1968, R. Hutton, black light trap. HT deposited in USNM.

Diagnosis. Interstriae 10 elevated to level of metacoxae; protibiae with an additional mesal tooth. Pronotum with a weak summit on anterior third. Distinguished from S. ingavorus Wood by the short strial and interstrial setae, and narrow pronotal asperities.

Description female. Length 1.2 mm, 2.3 × longer than wide; colour light brown. Head. Eyes weakly sinuate, separated above by 2.3 × their width. Frons flattened from upper level of eyes to epistoma; vestiture consisting of coarse plumose setae in two-thirds of the flattened area, setae reaching epistoma, with a small median shiny area on lower median third which is barely visible. Antennal club anteriorly densely pubescent, first two segments corneous, suture 1 partially marked laterally by coarse setae and a partial septum, suture 2 strongly procurved and marked by dense setae. Funiculus 5(4?)-segmented. Pronotum strongly reticulate, shallow punctures in posterolateral areas spaced by their diameter. Vestiture consisting of 4 anterior erect setae (4–0–0). Elytra smooth, striae not impressed, punctures shallow, in regular rows, separated by 1¯1.5 × their diameter; interstriae as wide as striae, punctures slightly smaller than those in striae, half the size of strial punctures. Vestiture consisting of very short coarse strial and interstrial setae. Legs. Procoxae separated by 0.3 × and mesocoxae 0.8 × the width of one procoxa. Protibiae narrow, distal teeth 1 and 2 of equal length, with 2¯3 tiny granules along the edge towards base; protibial mucro obtuse. Meso- and metatibiae with 5 lateral, socketed, thin teeth on distal third. Ventral vestiture. Setae on metanepisternum bifid, on metasternum simple.

Male. Unknown.

Key (Wood 1982). Keys to couplet 49, S. ingavorus , but differs as noted in the diagnosis.

Etymology. The name aureus is a Latin masculine nominative adjective meaning golden (in a beautiful sense), referring to the golden setae in the female frons, thereby aureifrons .

Biology and distribution. This species is only known from the type locality in Panama, in low altitude rain forest.
