Type material. Holotype, female: Costa Rica, San Jose / Cartago, km 69, Int. Amer. Hwy. nr. Tres de Junio , 2600m 09°39’30’’N, 83°51’30’’W, 7.vi.1997, R. Anderson, wet cloud forest litter, 97-004A. HT deposited in FSCA. GoogleMaps

Diagnosis. Interstriae 10 sharply elevated to level of ventrite 1; protibiae with a distinct additional mesal tooth near tarsal insertion. Lateral carina on pronotum strongly curved dorso-ventrally; pronotum from above appearing constricted on posterior fourth. Distinguished from a group of distantly related species near S. semipunctatus Wood and S. clusiacolens Wood by erect interstrial setae in rows combined with the presence of very short strial setae on the elytra.

Description female. Length 2.7 mm, 2.45 × longer than wide; colour reddish brown to black. Head. Eyes entire, separated above by 2.8 × their width. Frons convex on upper two-thirds, weakly impressed below; surface reticulate with few scattered punctures; vestiture consisting of a brush of short golden setae in impressed area, denser on epistoma. Antennal club with two obliquely procurved sutures marked by fine setae, first two segments corneous. Funiculus 6-segmented. Pronotum strongly reticulate, small punctures spaced by 3¯5 × their diameter. Vestiture consisting of 6 erect setae (4–2–0), and scant, short, fine, interspersed setae. Elytra generally smooth and shiny, striae weakly impressed, punctures distinct, in regular rows, separated by 1¯2 × their diameter; interstriae 3 × wider than striae, punctures minute. Vestiture consisting of erect interstrial setae of variable length, and much shorter recumbent strial setae. Legs. Procoxae separated by 0.8 × and mesocoxae 1.2 × the width of one procoxa. Protibiae narrow, distal teeth 1 and 2 of equal length, with 4¯5 tiny additional granules along the edge towards base; protibial mucro obtuse. Meso- and metatibiae with 6 lateral, socketed teeth on distal third. Ventral vestiture. Setae on metasternum and metanepisternum simple.

Male. Unknown. The sex of the type (female) was determined based on the single sclerotized terminal tergite (seven in total).

Key (Wood 1982). Keys to couplet 25, S. clusiacolens View in CoL , with no further match.

Etymology. The name is composed by the Latin masculine genitive adjective curvi (from curvus) and the masculine nominative adjective costatus, referring to the strongly dorsoventrally curved lateral costa of the pronotum.

Biology and distribution. This species is only known from the type locality in Costa Rica, in high altitude cloud forest.
