DIAGNOSIS: As for the subgenus (refer to page 32).

DESCRIPTION: Female. Total body length 8.5 mm; forewing length 4.6 mm. Head length 2.1 mm. Lower third of clypeus below lower tangent of compound eyes. Basal vein distad cu-a by 3 times vein width; 1r-m confluent with 1m-cu; 2rm distad 2m-cu by 3 times vein width; first submarginal cell about as long as combined lengths of second and third submarginal cells; second submarginal cell parallel-sided; distal hamuli arranged 3-1-1-2.

Clypeus and supraclypeal area with widely scattered faint, coarse punctures, integument between faintly imbricate. Face and vertex minutely

punctured, punctures separated by width or less, integument otherwise faintly imbricate. Gena as on face except punctures become separated by two times puncture width on lower third. Postgena faintly imbricate and impunctate. Pronotum faintly imbricate. Mesoscutum and scutellum imbricate with very widely scattered, faint punctures. Metanotum weakly rugulose. Preepisternum coarsely punctured, punctures contiguous on upper third, separated by width or less on lower twothirds. Mesepisternum coarsely punctured, punctures separated by puncture width or less, integument otherwise granular; hypoepimeron weakly rugulose with minute punctures along anterior third separated by less than a puncture width. Metepisternum weakly rugulose. Propodeal lateral surface faintly imbricate with widely scattered coarse punctures; posterior surface faintly imbricate; basal area imbricate with faint basal striae. Terga and sterna imbricate.

Mandible and labrum brown. Head dull metallic green with a few faint metallic copper highlights except clypeal apex brown. Mesosoma as on head; legs brown; wings hyaline, venation brown. Terga dark brown with a few faint metallic green highlights; sterna brown.

Pubescence golden and generally sparse except as indicated: on mesoscutum, scutellum, and metanotum fuscous; on outer surfaces of meso- and metatibiae, basitarsi, tarsomeres 2–4 long, simple, fuscous, and stiff; on terga fuscous.

Male. Unknown.

HOLOTYPE: Female , Miocene amber of the Dominican Republic ( MACT), accession number M- 2521.

ETYMOLOGY: The specific epithet is a combination of the Greek words leptos (meaning ‘‘small’’) and lobos (meaning ‘‘lobe’’) and refers to the weakly developed epistomal lobe that protrudes into the basal margin of the clypeus.
