Type material.

Holotype, female: Costa Rica, Prov. Heredia, 11 km SE La Virgen, 450-550 m, 10°20'N, 84°05'W, 17 Mar. 2003, INBio-OET-ALAS transect, 05/F/02/30, INB0003605900. Allotype, male: same data as holotype, 05/F/02/30 (INB0003605847). Paratypes: same data as holotype, 05/F02/13 (INB0003605727) (1); same data except 16 Feb., 05/F/01/24 (1); same data except 12 Apr., 05/F/03/37 (INB0003605900) (1). Holotype and 2 paratypes are deposited in MNCR, 1 paratype in ZMBN, 1 in USNM.

Diagnosis.

Interstriae 10 carinate to level of ventrite 1; protibiae with an additional mesal tooth near base of tooth 2. Distinguished from the very similar S. callosus Jordal & Kirkendall (described below) by the convex female frons which lacks a callus above epistoma, by the abundance of confused interstrial micro-punctures, and the entire eyes which are more broadly separated above.

Description, female.

Length 1.3-1.5 mm, 2.7 × as long as wide; color black. Head. Eyes entire, separated above by 2.8-3.1 × their width. Frons convex, short; surface weakly reticulate, more strongly so on vertex, with large punctures intermixed with micro-punctures on lower half. Vestiture consisting of fine setae from below upper level of eyes to epistoma. Antennal club and funiculus not clearly visible on specimens. Pronotum shiny, with shallow small punctures spaced by 3-4 × their diameter; faint asperities present on anterior fifth. Vestiture consisting of 8 erect long setae (4 –2– 2). Elytra smooth and shiny, cuticle slightly wrinkled at interstriae 1 and 2; striae 1 and 2 weakly impressed, others not, punctures small, deep, associated with a micro-puncture and together appears like one elongated puncture, each pair separated in rows by less than their length; interstriae 3-4 × as wide as striae, with abundant, confused micro-punctures, particularly abundant on interstriae 1-5. Interstriae 10 carinate to level of ventrite 1. Vestiture consisting of about 40 erect setae regularly distributed on odd-numbered interstriae. Legs. Procoxae separated by 0.4 × and mesocoxae 0.9 × the width of one procoxa. Protibiae narrow, lateral teeth 1 and 2 of equal size, with 3 additional small teeth along the lateral edge towards base; an additional mesal tooth present near base of tooth 2; protibial mucro obtuse. Meso- and metatibiae with 6 and 5 small socketed lateral teeth on distal half and third, respectively. Ventral vestiture. Setae on metanepisternum and metasternum simple, on mesanepisternum bifid. Sclerolepidia very small elongated scales.

Male.

Near identical to female.

Etymology.

The Latin name mundus is a masculine adjective, meaning clean, pure, or neat, referring to the small size of the species, with few, very fine, setae on elytra and in the female frons, and the generally shiny appearance.

Biology and distribution.

This species is only known from the type locality at 500 m altitude in Costa Rica. Specimens were collected from three different fogging events (http://viceroy.eeb.uconn.edu/alas/canopy03.html). The species is morphologically very similar to other small Scolytodes species breeding in Clusia .
