description: Ipsiura marginalis (Brullé, 1846)
(Figs 123–128)
Chrysis marginalis Brullé, 1846: 41. Holotype ♀ [examined by photos]: FRENCH GUIANA, Cayenne (MNHN). Pleurocera (Ipsiura) marginalis: Linsenmaier 1959: 74.
Neochrysis (Ipsiura) marginalis: Bohart 1966: 142.
Ipsiura marginalis: Bohart 1985: 709.
Diagnosis. Ipsiura marginalis most closely resembles I. ellampoides (Ducke). It is readily distinguished from that and other Ipsiura species by the combination of following characters: fore wing with long M distal to discoidal cell; TFC completely closed medially, rectangular, with well-marked secondary lateral facial carina (TFC rounded and without secondary lateral facial carina in I. ellampoides); T3 with indistinguishable teeth (deflected teeth in I. ellampoides); lower posterior mesopleural margin with strong knob-like projections (absent in I. ellampoides) and metanotum elongated, strongly projected above the propodeal surface (not so well-developed in I. ellampoides).
Female description. Body (Fig. 123). Length: 12.2 mm. Coloration: head predominantly green, with bluish highlights on vertex; F1 green; mesosoma metallic green, with bluish highlights on dorsum, particularly on pronotum and mesoscutum; metasoma metallic green, with bluish purple stripes on dorsum of T2 and faintly indicated on T1; T3 with lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae greenish; tarsi brownish, basitarsi brownish green. Head: TFC enclosing the median ocellus, completely closed medially, forming a rectangular enclosure (Fig. 124); secondary facial carina well-developed laterally; F1 much longer than broad, about 1.9× as long as F2; scapal basin densely covered with silvery pubescence laterally, with distinct polished stripe medially. Mesosoma: fore femur with discrete flattened area on outer surface of distal margin, diameter of distal area subequal to diameter of proximal area; fore wing with long M distal to discoidal cell, ending near distal wing margin, R1 very short, slightly indicated (as in Fig. 145), medial cell asetose; dorsal surface of pronotum much wider than head; lower lateral pronotal surface smooth, punctate anteriorly, without distinct posterior area delimited by transverse ridge; metanotum elongated, strongly projected above propodeal surface; mesopleural lower posterior margin strongly carinate, along with distinct knob-like projections (Fig. 126). Metasoma: T3 with “two” deflected downward distal teeth (Fig. 125), pit row obsolescent, indicated by shallow and small pits, prepit swelling strongly convex; S2 spots medium-sized, separated medially about one-half spot diameter (Fig. 127). Punctation: fore femur punctate on outer surface; largest punctures on T1, mesopleuron and metanotum; shallow and spaced punctures on dorsum of T2 and T3, shiny interspace punctures.
Male. Unknown.
Variation. Body length 11.9–13.1 mm.
Hosts. Unknown.
Distribution. Brazil (AM, PA); French Guiana (Cayenne); Paraguay (Itapúa, Paraguarí) (Fig. 128).
Remarks. I. marginalis is the largest and most easily recognizable species in the genus.
