Mandibular formula 3:3. Upper portion of frons strongly projecting
anteriad, dorsal surface of head very long; occiput very
strongly concave, sharply margined. Clypeus set off by
distinct sulci. Scape and 2 basal flagellomeres strongly flattened
in females; flagellar formula apparently 0,2,3 in females, 0,4,1 in
males, which have a whorl of long setae at the base of each flagellomere; flagellar
peg sensilla elongate, spear-shaped. Pronotum very short
dorsally; mesoscutum smooth, mesoscutal midlobe with 1 pair of tiny setae (posterior
pair). Forewing distinctive in shape: submarginal vein only
slightly shorter than marginal vein and disc distinctly expanded beyond
venation; disc with distinct longitudinal fuscate band branching apically
(but sometimes fuscate area reduced to traces near venation in males); postmarginal vein
subequal stigmal vein length. Propodeum smooth, without median carina; petiolar foramen
very large. Petiole much broader than long. Compare with: Closterocerus,
1a-b: Callifrons face (left), and forewing (right)
2a-b: Callifrons female antenna (left), and male antenna (right)
Comments: 1 described
species: C. maculata Schauff, Yoshimoto, & Hansson. Certainly related to Omphale
and Closterocerus, but it is not clear to which it is most closely linked by
Closterocerus: Head not as elongate, without
hornlike projections. Shape and fuscate pattern of forewing never the same, though
somewhat similar in Closterocerus tau Girault.
Omphale: Head not as elongate, without
hornlike projections. Flagellum not flattened. Forewing not similarly shaped or patterned.
