Smith, F., 1859, Catalogue of hymenopterous insects collected by Mr. A. R. Wallace at the Islands of Aru and Key., Journal of the Proceedings of the Linnean Society of London, Zoology 3, pp. 132-158 : 156

1. Macromeris iridipennis .

M. caeruleo-nigra; abdomine iridescente, alis caeruleo-violaceoque splendide micantibus; pedibus mutieis, simplicibus.

Female. Length 12 lines. Blue-black; abdomen with a changeable iridescent pile; head and thorax with a black velvety pubescence; the metathorax very finely rugose and opake; the legs simple; the posterior tibiae villose within; the wings very dark brown, with a splendid violet and blue iridescence.

Male. Very closely resembling the female, but rather smaller; the anterior and intermediate femora more incrassate, and all the femora with a simple row of teeth or serrations on their inferior margins.

Hab. Aru.

Although this species of Macromeris is very similar in colour to the M. violacea of St. - Fargeau, the femora are not so thick as in that species, not in fact much more so than in the female; and the row of teeth beneath is a strong specific character.
