Diagnosis. Length 8.0–9.0 mm., length fore wing 7.5–8.5 mm.

Blackish species, with yellow marks on clypeus, gena and lateral face, antennae and legs dark brownish; tergum I and II black, terga IV–VI totally yellow; wings subhyaline, costal region blackish. Pubescence sparse, brownish. Macropunctures on frons, vertex, mesosoma and tergum I dense, coarse, metasomal tergum II with dense and small punctation. Clypeus longer than wide, apex truncate; gena narrow, less than half width of eyes; occiput margined; occipital carina dorsal only, not projecting; humeri rounded, not projecting, sometimes very lightly projecting; tegula hardly more than twice as long as broad, posterior margin truncate; metanotum compressed; metanotum with a wide tubercle, apically truncate; propodeal orifice sides converging, almost pointed dorsally; metasomal tergum I petiolate, transversely widened posteriorly, without preapical transverse carina; tergum II with feeble traces apico-discal tubercle.

Comments. According to Kojima and Carpenter (1998), the holotype of Icaria xanthura de Saussure, 1854, is in the Natural History Museum, London, and the species is a senior synonym of Charterginus aberrans . We did not examine the holotype, but we did examine the lectotype of Charterginus huberi, a junior synonym. The nest was photographed at AMNH (Fig. 7A). Charterginus xanthura collects Mullerian bodies from Cecropia obtusa trees in French Guiana (LaPierre et al. 2007), and in Cecropia concolor Willd., C. palmata Willd., C. purpurascens C.C. Berg, C. aff. membranacea, and C. aff. obtusa in Manaus, Amazonas, Brazil (recorded by de Aguiar et al. in press.).
