1. Calloeneis lynne Gordon and Hanley , new species

Description. Male holotype. Length 2.0 mm, width 1.7 mm; dorsal surface shiny, head strongly alutaceous, elytron with faint trace of microsculpture, lateral 1/4 of basal abdominal ventrite 1 densely alutaceous, ventrite 5 entirely alutaceous. Color light brownish yellow ( Fig.1 ); head yellow; pronotum with median 2/3 darker brownish yellow; pro-, meso-, metasternun black; abdominal ventrite 5 with median 1/3 dark brown. Head with dense punctures separated by a diameter or less; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than one to twice a diameter; prosternal punctures small, indistinct, separated by about a diameter; mesosternal punctures larger than on prosternum, separated by less than a diameter, metasternal punctures small, separated by two or three times a diameter medially, becoming widely spaced on lateral 1/3; basal abdominal ventrite with fine punctures separated by about three times a diameter medially, ventrites 2–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head slightly narrowed from vertex to clypeus, medially depressed, 1.5 times as wide as eye, apex weakly curved ( Fig.2 ); eye canthus short, about half width of eye. Prosternum with lateral carina on each side curved, extended from apex of intercoxal process to lateral margin of prosternum. Epipleuron not descending externally. Postcoxal line on basal abdominal ventrite curved except median portion flattened, extended nearly to rear margin of ventrite. Genitalia long, penis guide as long as paramere, basal 1/2 wide, apical 1/2 strongly narrowed to rounded apex; paramere slender, parallel sided, weakly curved, apex rounded ( Fig. 3, 4 ); penis long, slender, apex attenuate; basal capsule short, wide, inner arm slightly produced apically, outer arm nearly truncate ( Fig. 6 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Colombia, Antioquia, (Sureste) ll, Jardin 5 km SE Tebaida,car. Riosucio km 10, 5°34′N –75°46′, 220 m, 8.IV.2016 a, R.Constantin. ( CTNI).

Other specimens. 4, Colombia, Candelaria, Colegio, Gacheta, Palmira. ( USNM). Female

Remarks. This species is externally inseparable from C. sheri and therefore male genitalia must be examined. Females listed under “Other specimens” are probably this species but cannot be determined with certainty. Female genitalia figured are probably those of C. lynne .
