Description. Male holotype. Length 2.6 mm, width 2.5 mm; dorsal surface shiny, head slightly alutaceous. Color black; head yellow; pronotum reddish yellow, narrow, obscure brownish red macula on base in median 1/3; elytron with narrow, reddish yellow vitta on lateral margin, vitta narrow from base to apical declivity, then widened from declivity to sutural margin ( Fig. 73 ); venter yellow except metasternun brownish yellow. Head punctures small, separated by less than a diameter; pronotal punctures as large as on head, separated by less than to twice a diameter; elytral punctures as large as on pronotum, separated by less than to 4 times a diameter, becoming larger, denser toward lateral margin; prosternum with small punctures separated by less than a diameter; mesosternum with punctures larger than on prosternum, separated by a diameter or less; metasternum with punctures smaller than on prosternum, separated by 2 to 4 times a diameter in median 2/3, punctures becoming absent in lateral 1/3; abdominal ventrites 1, 2 with coarse punctures separated by about 3 times a diameter; ventrites 3–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons parallel sided, 1.5 times as wide as eye, clypeal apex widely emarginate, lateral angle abruptly curved ( Fig. 74 ); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side straight, extended from apex of intercoxal process nearly 2/3 distance to apex of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite curved, extended 3/4 distance to rear margin of ventrite. Genitalia with basal lobe as long as paramere, sides parallel from base to apical 7/8, apical 1/8 narrowed to broadly rounded apex; paramere slender, slightly curved, apex rounded ( Fig. 75, 76 ); penis lost.

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Armero , Colombia, Tol, 13.V.40, Murillo No 101. ( USNM).

Remarks. Pentilia krystal may be recognized by the relatively narrow, pale lateral border on each elytron, but it is not an extremely distinctive taxon.
