12. Calloeneis angelica Gordon and Hanley , new species

Description. Male holotype. Length 2.0 mm, width 1.7 mm; dorsal surface shiny with faint trace of microsculpture, head distinctly alutaceous. Color yellow; head with small, irregular, brown, transverse macula on frons between eyes; elytron with small, dark brown macula on suture in basal 1/2, slender, irregularly arcuate vitta extended from base inside humeral angle across humeral callus almost to apical declivity ( Fig. 49 ); venter yellow except pro-, meso-, and metasternum black; abdomen yellow except median 1/3 of basal ventrite, median anterior margin of ventrite 2 dark brown. Head with coarse punctures separated by less than a diameter; pronotal punctures small, separated by a diameter or less; elytral punctures slightly larger than on pronotum, separated by up to twice a diameter; prosternal punctures large, separated by about a diameter; mesosternal punctures as large as on prosternum, punctures on metasternum large, separated by about a diameter, absent medially, present laterad of middle, absent in lateral 1/3; basal abdominal ventrite impunctate medially, ventrites 1, 2 with fine punctures separated by up to three times diameter medially, ventrites 3–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons parallel sided medially, 1.2 times as wide as eye, clypeal apex truncate ( Fig. 50 ); 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 weakly descending externally. Postcoxal line on basal abdominal ventrite curved, extended 3/4 distance to rear margin of ventrite. Genitalia with penis guide slightly longer than paramere, slender, wide at base, tapered to apical 3/4 then more strongly tapered to abruptly rounded apex, flanked on each side with slender appendix extended 3/4 length of penis guide; paramere slender, apex acute ( Fig. 51, 52 ); penis short, robust, curved apex briefly attenuate; basal capsule wide, flat, inner arm apically hooked, outer arm wide, apically rounded ( Fig. 53 ).

Female. Unknown.

Variation. Maculae on elytron pronounced, wide, arcuate vitta reaching apical declivity, extended to sutural vitta.

Type material. Holotype male: COLOMBIA, Garzon, Huila, 8.XI.39, Murillo No. 54 ( USNM).

Other specimen. Same data as holotype, dorsal color pattern as in variation above.

Remarks. Calloeneis angelica is recognized by the distinctive elytral color pattern not shared with other Calloeneis species.
