Type material. Holotype, male(?): Panama, Chiriqui Prov, La Culebra Trail , 1750m, 3km N. Boquete, 9 Aug. 1995, AR Gillogly . Holotype deposited in TAMU .

Diagnosis. Interstriae 10 elevated to level of ventrite 2, interstriae 9 sharply elevated to apex; protibiae without additional mesal tooth. Male mandibles greatly enlarged. Closely related to S. montanus Jordal , but is much larger, nearly glabrous, punctures on pronotum much smaller, interstriae 9 is sharply raised for its entire length, and the posterior face of protibiae is lacking an additional mesal tooth.

Description male. Length 3.1 mm, 2.0 × longer than wide; colour reddish brown. Head. Eyes entire, separated above by 4.2 × their width. Frons convex, slightly impressed above epistoma, shiny, with scant, simple, hair-like setae. Antennal club with three clearly marked segments, the first two corneous. Funiculus 6-segmented. Pronotum smooth, shiny, densely punctured. Vestiture consisting of 8 erect setae (4–2–2). Elytra smooth, striae strongly impressed, punctures tiny, shallow, separated in regular rows by 2¯3 × their diameter, interspersed by smaller punctures of the same size as interstrial punctures; interstriae approximately 4 × wider than striae, punctures two-thirds the size of those in striae, mainly in rows, some intermixed with striae. Appears glabrous, but tiny strial and interstrial setae on declivity, some longer erect setae at apex and on interstriae 9. Legs. Procoxae separated by 1.3 × and mesocoxae 1.4 × the width of one procoxa. Protibiae broader towards apex, broadest at level of tooth 2, distal teeth 1 and 2 of equal length, tooth 2 with socketed denticle exposed, with 5¯6 tiny additional spines or granules along the edge towards base; protibial mucro very short and straight. Meso- and metatibiae with 7–8 lateral, socketed, thin teeth on distal half. Ventral vestiture. Setae on metasternum and metanepisternum simple.

Female. Not known.

Key (Wood 1982). Belongs to a unique group of Scolytodes View in CoL not included in Wood’s (1982) key. With some uncertainty one may navigate to couplet 9, but this species is not close to S. plumeriae Wood. View in CoL

Etymology. The name potens , a Latin noun (third declension) meaning strong or powerful, referring to the large size, stout body shape, and huge mandibles.

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