Euderomphale Girault, 1916 comparative info return to: prev home
Eyes setose. Transverse frontal groove absent, but presumably should be located near median ocellus as a straight line; scrobal depressions not present as grooves, uniting near center of face, the longitudinal depression ending at the median ocellus. Clypeus defined dorsally by a semicircular sulcus. Malar sulcus incomplete, directed posteriad. Vertex with transverse groove extending between median ocellus and lateral ocelli; occiput with longitudinal and transverse grooves. Flagellum 6-segmented; first pair of flagellomeres tiny and anelliform, 3rd flagellomere longer than broad; 3-segmented club much longer than rest of flagellum, with apical spicule. Pronotal collar not formed; mesoscutal midlobe with 2 pairs of setae; axillae advanced entirely anteriad of scutellar margin, defined by complete sulcus curving at right angle (sinuate in E. sinuata LaSalle group), dorsal surface of axilla about as long as broad; scutellum much broader than long, shorter than mesoscutum, with 2 pairs of tiny setae. Postmarginal vein subequal to stigmal vein in length; marginal vein much longer than costal cell; submarginal vein with 2 dorsal setae; females of E. sinuata brachypterous. Propodeum extremely short. Petiole transverse. Gaster unsculpted, not metallic; males and females known to have antero-lateral abdominal glands. Color never metallic. Compare with: Neopomphale.
