Chrysis brevispina Ducke, 1911: 102 . Holotype Ƌ [examined]: BRAZIL, Pará, A. Ducke ( MZUSP). Neochrysis (Ipsiura) brevispina: Kimsey & Bohart 1981: 78 .

Ipsiura brevispina: Bohart 1985: 709 .

Diagnosis. Ipsiura brevispina most closely resembles I. marginalis (Brullé) and I. ellampoides (Ducke) . It can be distinguished from these and other Ipsiura species by the following combination of characters: fore wing with long M distal to discoidal cell (short in most Ipsiura ), R1 absent (slightly indicated in I. ellampoides ); T3 with four acute distal teeth (indistinguishable teeth in I. ellampoides and I. marginalis ) and T2 with narrow basolateral translucent margin (absent in I. ellampoides and I. marginalis ).

Holotype redescription. Body ( Fig. 26 ). Length: 8.7 mm. Coloration: head predominantly green, with purplish highlights on vertex; F1 brownish green; mesosoma metallic green, with purple highlights on dorsum, particularly on pronotum and mesoscutum; metasoma metallic green, with distinct purplish stripes on dorsum of T1 and T2; T3 with shiny interspaces between punctures, broad whitish spot basolaterally; distal margin of T3 ambercolored; wing membrane light brown, with brown veins; femora and tibiae green; tarsi brownish, hind basitarsus brownish green. Head: TFC enclosing the median ocellus, round enclosure, uninterrupted medially ( Fig. 27 ); F1 longer than broad, 1.3× as long as F2 length; scapal basin with sparse silvery pubescence. Mesosoma: fore femur without ventral tooth-like projection or flattened area on outer surface of distal margin, diameter of distal area onehalf diameter of proximal area; hind tibia with some long setae; fore wing with long M distal to discoidal cell, ending near distal margin of wing, R1 absent (as in Fig. 145 ), medial cell asetose; dorsal surface of pronotum wider than head; lower lateral pronotal surface smooth, without distinct posterior area delimited by transverse ridge; metanotum elongate, projecting above propodeal surface; mesopleural lower posterior margin strongly carinate, with distinct equally separated tooth-like projections. Metasoma: T3 with four acute distal teeth ( Fig. 28 ), prepit swelling very low, sloping gently, pit row obsolescent, indicated by tiny lateral pits; T2 with narrow translucent margin basolaterally; S2 spots small, round, separated medially at least by one spot diameter ( Fig. 29 ). Punctation: tiny punctures on outer surface of fore femur; largest punctures on T1, mesopleuron and metanotum; T3 with tiny and well-separated punctures, shiny interspaces.
