Ipsiura nigriventer Bohart, 1985 

( Figs 141–146View FIGURES 141 – 146)

Ipsiura nigriventer Bohart, 1985: 717  . Holotype Ƌ [examined]: MEXICO: Oaxaca, Matias Romero (BME).

Diagnosis. Ipsiura nigriventer  most closely resembles I. leucocheila (Mocsáry)  and I. leucocheiloides (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 M in I. leucocheila  and I. leucocheiloides  ); integument of propodeal foveae dull (polished, shiny in all other Ipsiura  species) and the unusual large S2 spots (medium-sized in I. leucocheila  and I. leucocheiloides  ).

Female description. Body ( Fig. 141View FIGURES 141 – 146). Length: 8.1 mm. Coloration: head predominantly green, with dark blue highlights on vertex; F1 greenish brown; mesosoma metallic green, with bluish purple transverse stripes on dorsum of pronotum, mesoscutum with broad purplish blue band; metasoma metallic green, with transverse bluish purple stripes on dorsum of T2 and faintly marked on T1; integument of propodeal surface dull; T3 with dark bluish highlights, narrow lateral whitish spot basolaterally; wing membrane light brown, with brown veins; femora and tibiae green; tarsi brown, meso- and hind basitarsus green. Head: TFCAbout TFC forming an incomplete arc, interrupted medially ( Fig. 142View FIGURES 141 – 146); F1 longer than broad, 1.3× as long as F2; scapal basin with silvery pubescence. 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 ( Fig. 145View FIGURES 141 – 146); dorsal surface of pronotum wider than head; lower lateral pronotal surface smooth, sparse punctures anteriorly, without distinct posterior area delimited by transverse ridge; metanotum with deep punctation, appearing faintly cristate; mesopleural lower posterior margin carinate, with distinct tooth-like projections. Metasoma: T3 with four acute distal teeth ( Fig. 143View FIGURES 141 – 146), pit row well-developed, indicated by large foveae, prepit swelling very low, sloping gently; S2 spots unusual large, touching medially ( Fig. 144View FIGURES 141 – 146). Punctation: fore femur coarsely punctate on outer surface; largest punctures on T1, mesopleuron and metanotum.

Male. Same as female, except for the characteristic shape of S2 spots as shown in Fig. 144View FIGURES 141 – 146, the broad dark band occupying much of the dorsum of meso- and metasoma, and the femora with plusome long silvery setae.

Variation. Despite the widespread distribution, I. nigriventer  is quite morphologically uniform. The most conspicuous variation observed in this species is body length and coloration. The specimens from southeastern USA to Costa Rica are as longer as holotype, and predominantly bluish as holotype. On the other hand, the Brazilian specimens, especially the specimens collected in São Paulo: Luis Antonio (LRRP) and Minas Gerais: Marliéria (UFES) are smaller (about 7.1–7.8 mm) and predominantly green (as seen in Figs 141–143View FIGURES 141 – 146).

Host. Unknown.

Distribution. Brazil (AM, MG, MT, PA, SP); Costa Rica (Guanacaste); Mexico (Michoacán, Oaxaca, Yucatán); USA (Texas) ( Fig. 146View FIGURES 141 – 146).
