Lyroda concinna (F. Smith)

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.

GEOGRAPHIC DISTRIBUTION (Fig. 3). Northern South America.

RECORDS. BRAZIL: Amazonas: Tefé (1 ♂, CAS) . Pará: Belém: APEG [= Área de Pesquisa Ecológica do Guamá ] Forest (1 ♂, CNC; 1 ♂, FSCA), Tapajós River (1 ♀, BMNH, holotype of Morphota concinna ), no specific locality (1 ♂, CAS).
