Eomacropis , new genus

TYPE SPECIES: Eomacropis glaesaria Engel , new species.

DIAGNOSIS: As for the tribe (see above).

DESCRIPTION: Galea with long setae at apex; maxillary palpus six­segmented (basal segment not visible in figure 21 but is visible from a lateral view of the head). Width of labrum three times greater than length; surface impunctate; short, median, distal process with long setae along margins. Malar space linear, length much less than basal mandibular width, base of mandible nearly touching lower margin of compound eye. Mandible with strong subapical tooth. Epistomal sulcus forming approximately orthogonal angle (fig. 21). F1 longer than F2 (fig. 21). Compound eye weakly emarginate above level of antennal sockets (fig. 21); compound eyes without setae. Gena slightly broader than compound eye in lateral view. Preoccipital area sharply angled but not carinate. Scrobal groove present. Claw with inner tooth, arolium present (fig. 24); metatibial and metabasitarsal scopa composed of densely plumose setae; setae of apical truncation of metabasitarsus not parted to expose narrow strip of integument. Basal vein straight, basad cu­a, basal vein twice as long as first abscissa of Rs (fig. 23); prestigma shorter than margin of pterostigma inside of first submarginal cell, prestigma about as wide as pterostigma; pterostigma inside of marginal cell slightly convex (fig. 23). Basal area of propodeum impunctate, granular and without pubescence (plesiomorphically similar in this respect to Macropis s.s.).

ETYMOLOGY: The new genus­group name is a combination of eo ­ (a reference to the epoch name, Eocene) and Macropis , type genus of the Macropidinae . The name is feminine.
