Type material. Holotype, female: Panama, San Blas Prov , Nusagandi, 320m, 9°19’ N, 78°55’W, 27¯ 28 May 1995, FIT, Gillogly & Stockwell. Type deposited in TAMU. GoogleMaps

Diagnosis. Interstriae 10 elevated to level of ventrite 1; protibiae with an additional mesal tooth. Superficially similar to S. parvulus Wood and other species in the acares group, but differs strongly by having distinctly impressed striae and coarse granules at the base of interstrial setae. Also superficially similar to S. montanus Jordal and S. potens Jordal , but much smaller, with scattered, long, erect setae on elytra.

Description female. Length 1.4 mm, 2.2 × longer than wide; colour brown. Head. Eyes entire, separated above by 2.4 × their width. Frons weakly concave on a circular area occupying three-quarter the width frons on lower half; impressed area densely punctate with fine setae, impunctate and glabrous above. Antennal club setose, without sutures. Funiculus 5-segmented. Pronotum smooth, shiny, punctures very faint. Vestiture consisting of 6 erect setae (4–2–0). Elytra smooth, shiny, striae strongly impressed, punctures small, deep, separated in regular rows by 1 × their diameter; interstriae approximately 4¯5 × wider than striae, punctures tiny, obscure. Vestiture consisting of 5¯7 erect, long setae on each odd interstriae, with a coarse granule at base of setae. Legs. Procoxae separated by 0.7 × and mesocoxae 1.1 × the width of one procoxa. Protibiae narrow, distal teeth 1 and 2 of equal length, 2¯3 tiny granules along the edge towards base; protibial mucro obtuse. Mesotibiae with 6 lateral, socketed teeth on distal half, metatibiae with 5 lateral, socketed teeth on distal third. Ventral vestiture. Setae on metasternum and metanepisternum simple.

Male. Not known.

Key (Wood 1982). With much hesitation the species may key to couplet 22 and 23, without matching S. c lusiae Wood or similar species.

Etymology. The Latin name minimus is a masculine nominative adjective, meaning smallest, and refers to the much smaller size compared to S. montanus Jordal and S. potens Jordal

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