Icteranthidium Michener, 1948 View in CoL

Icteranthidium Michener, 1948: 25 View in CoL . Type species: Anthidium limbiferum Morawitz, 1875 View in CoL , by original designation.

Diagnosis. According to Michener (2007), the diagnosis of the genus is as the follows: Moderate-sized (body length: 7.5–18.0 mm); mandible with 4 short and large teeth in female and with 3 large teeth in male; maxillary palpus twosegmented; subantennal suture straight or nearly so; preoccipital ridge not carinate above but strongly so laterally, the carina slanting forward to the posterior mandibular articulation; pronotal lobe strongly lamellate; axilla usually pointed posteriorly; omaulus lamellate, but not continued onto venter of thorax; propodeum without fovea behind spiracle and row of pits across upper margin; arolia absent; basal vein of forewing nearly straight and meeting vein Cu at acute angle, jugal lobe of hind wing less than half as long as vannal lobe; T2 without a strong carina across summit of basal concavity; posterior margins of terga not depressed; T6 of female concave in profile, the margin convex with a median notch; T7 of male with a midapical projection, sometimes also a tooth or projecting lobe at each side.
