Morphota concinna F. Smith, 1856:294, ♀. Holotype by monotypy: Brazil: Pará: Tapajós River (BMNH), examined. – As Lyroda concinna: Kohl, 1885:267 (new combination, in checklist of world Lyroda); Dalla Torre, 1897:696 (in catalog of world Hymenoptera); Iwata, 1933:7 (in list of world Lyroda); R.

RECOGNITION. Like Lyroda fasciata, the gaster is red basally in L. concinna . It differs from that species in having 10–15 roughly parallel longitudinal ridges on the propodeal dorsum (Fig. 2) and the mesopleural vestiture not concealing the integument.

DESCRIPTION. Propodeal dorsum with 10–15 roughly parallel longitudinal ridges, mainly extending to the dorsum’s apex (Fig. 2), but reaching only about two thirds of dorsum’s length in male from Tefé (CAS); propodeal side unridged, without spiracular groove. Tergum I with only a pair of basomedian carinae. Mesopleural vestiture not concealing integument.

Body black, but gaster red basally; legs black or tibiae partly dark red. Forewing membrane in some specimens with slightly darkened, subapical, transverse fascia.

♀: Free margin of clypeal lobe with three teeth on each side of lobe. Length 7.6 mm.

♂: Free margin of clypeal lamella slightly arcuate to slightly weaving. Length 5.6–7.6 mm.
