Diagnosis. Distinguishable from its congeners on the basis of a unique combination of color, elytral pattern, and pronotal vestiture.

Description (Holotype). Length: 7.30 mm. Color: Deep relucent blue; apices of maxillary palpi, antennomeres 1–2 (in part) testaceus; tarsi reddish brown; elytra with antemedian and subapical eburneus fasciae, the former complete to lateral margins, the latter interrupted at epipleural folds, both narrowly interrupted at suture ( Fig. 1 ); abdomen orange testaceus. Head: antennae rather robust, extending to base of pronotum; club well-developed; gular process rectangulate/spatulate (not transverse); front bi-impressed; surface densely, subconfluently punctate, sparsely set with short, coarse, whitish setae. Pronotum: about as long as wide; distinctly narrower than elytra at base; transverse impression distinct, broadly ‘‘U’’ shaped; surface shining, rather finely, closely punctate and transversely rugulose; pubescence coarse, mostly whitish, absent from two transverse ovoid areas on disk at either side of middle. Elytra: elongate (ratio of length to maximum width 41:22), widest behind middle; basal margin bisinuate; humeri pronounced, convexly rounded; subbasal tumescences faintly indicated; disk flattened at middle; surface shining, moderately densely punctate and dimpled throughout, indistinctly covered with short, suberect and somewhat longer erect, mostly dark setae, with a sparsely arrayed concentration of coarse, white setae across base and on apices; lateral margins broadly deflexed at middle; apical slope gradual; apices separately rounded, dehiscent. Metasternum: convex; surface finely punctate. Abdomen: shining, feebly, very sparsely punctate, negligibly pubescent; abdominal apex without setal daggers. Genitalia: tegmen not sagittate apically.

Variation. Size ranges from 7.30 mm – 9.75 mm. In some specimens the pronotum reflects aquamarine tints. The eburneus elytral fasciae vary somewhat in shape; most notably, the antemedian band is rounded internally in some specimens, whereas in others it is truncated by the sutural margin.

Discussion. The new species shares some characteristics with members of the clerine genus Colyphus Spinola as defined by Ekis (1977 b). These include a lustrous, uniformly punctate and elongate elytra, and a convex pronotum. Unlike those of Colyphus , however, the antennae of E. addisoni are relatively short and robust, and do not extend beyond the pronotum. Furthermore, the male of E. addisoni lacks the distinctly sagittate tegmen of most Colyphus species. I have therefore chosen to place the new species in Enoclerus , though its affinities within this speciose and diverse genus are unclear.

Note on Habitat. All specimens were taken in Malaise traps in the Andean zone of Colombia, at an elevation of 2,855 m. The habitat at the collection site has been characterized as ‘‘fog forest.’’

Etymology. It is with great pride and pleasure that I name this species for my son, Addison Darwin Rifkind, an observant and enthusiastic field assistant and budding naturalist in his own right.
