Lectotype ♀ [examined]: BRAZIL : Pará , Óbidos coll. A. Ducke ( MZUSP ). Designed by Bohart, in Kimsey & Bohart (1991: 510) . Neochrysis ( Ipsiura ) longiventris : Bohart 1966 : 142 . Ipsiura longiventris : Bohart 1985 : 711 . Diagnosis. Ipsiura longiventris most closely resembles I. prolixa Bohart and I. klugi (Dahlbom) . It can be distinguished from these and other Ipsiura species by the following combination of characters: T2 with narrow basolateral translucent rim (absent in I. prolixa and I. klugi ); large S2 spots (medium-sized to small in I. prolixa and I. klugi ); T3 with six acute distal teeth and low, indistinct, sloping gently prepit swelling (prepit swelling absent in I. klugi and I. prolixa ); and the TFC almost completely closed medially (widely interrupted in I. klugi and I. prolixa ). Lectotype redescription. Body ( Fig. 119 ). Length: 7.2 mm . Coloration: head predominantly green, with faint bluish highlights on vertex; F1 brown; mesosoma metallic green, with faint bluish highlights on dorsum of pronotum and mesoscutum; metasoma metallic green, with faint transverse bluish purple stripes on dorsum of T1 and T2; T3 with faint bluish highlights dorsally, with lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae greenish; tarsi brownish, hind basitarsus brownish green. Head: TFC forming long arc, slightly interrupted medially ( Fig. 120 ); scapal basin densely covered with silvery pubescence; F1 longer than broad, 1.2× as long as F2. Mesosoma: fore femur without ventral tooth-like projection, slightly flattened on outer surface of distal margin, diameter of distal area subequal to diameter of proximal area; fore wing with short M distal to discoidal cell, R1 shorter than stigma (as in Fig. 190 ); dorsal surface of pronotum wider than head; lower lateral pronotal surface irregularly punctate anteriorly, with indistinct posterior area delimited by faint transverse ridge; metanotum rounded, without differentiated surface; mesopleural lower posterior margin carinate, with indistinct tooth-like projections. Metasoma: T3 with six acute distal teeth ( Fig. 121 ), pit row well-developed, with large and deep foveae, prepit swelling low, sloping gently; T2 with narrow basolateral translucent border; S2 spots medium-sized, round, nearly reaching each other medially ( Fig. 122 ). Punctation: fore femur impunctate on outer surface; largest punctures on T1, mesopleuron and metanotum. Male. Unknown. Hosts. Unknown. Distribution. Brazil : Pará , Óbidos ( Fig. 30 ). Material examined. Lectotype only.
