7. Calloeneis myra Gordon and Hanley , new species

Description. Male holotype. Length 2.1 mm, width 1.9 mm; dorsal surface shiny, head distinctly alutaceous. Color yellow; head with small, hourglass shaped brown macula on middle of frons; pronotum with small, triangular, brown macula at middle on apical margin, small, dark brown macula present medially on base anterior to scutellum; elytron with four dark brown maculae, sutural macula narrowly extended from scutellum onto apical declivity then laterally and anteriorly onto lateral 1/4 of elytron, irregular humeral macula from basal margin posteriorly and laterally around humeral callus, small, oval brown macula just anterior to apical declivity near suture, irregular, obliquely transverse brown macula on lateral 1/3 of elytron on and anterior to apical declivity ( Fig. 26 ); ventral surface entirely yellow except median 1/3 of basal abdominal ventrite pale brown. Head with dense punctures separated by less than a diameter; pronotal punctures small, separated by a diameter or less; elytral punctures as large as on pronotum, separated by less than 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 large, separated by a diameter or less medially, absent in lateral 1/3; abdominal ventrites 1, 2 with fine punctures separated up to three times diameter medi- ally, ventrites 2–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons slightly narrowed from base to apex, depressed medially, 1.2 times as wide as eye, clypeal apex weakly curved ( Fig. 27 ); 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, extended 2/3 distance to rear margin of ventrite. Genitalia long, penis 2/3 as long as paramere, sides sinuate from base to apex, flanked on each side by long, apically rounded appendix, apex of penis guide broadly rounded, barely perceptibly emarginate ( Fig. 28, 29 ); penis lost.

Female. Unknown.

Type material. Holotype male: 1100m. Rancho Grande Aragua, Venezuela, Feb. 22–23, 1971, H. & A. Howden ( USNM).
