description: Ipsiura bohartiana Lucena sp. nov.
(Figs 13–20)
Diagnosis. This species most closely resembles I. leucocheiloides (Ducke) and I. nigriventer Bohart. Ipsiura bohartiana sp. nov. is readily distinguished by the following combination of characters: T3 with four acute distal teeth (sometimes obtuse in I. leucocheiloides), without lateral whitish spot (whitish spot present in I. leucocheiloides and I. nigriventer); TFC forming a subrectangular enclosure (TFC rounded in I. leucocheiloides, widely interrupted medially in I. nigriventer); metasomal rim with conspicuous golden brown setae (silvery to golden setae in I. leucocheiloides and I. nigriventer); wing membrane dark brown (light brown in the most species); R1 strongly reduced (present in I. leucocheiloides and I. nigriventer), short M distal to discoidal cell (long M in I. nigriventer) and by the distinct bisected lower genal space (not bisected in I. leucocheiloides and I. nigriventer). Additionally, the aedeagus lobes rounded and blunt apically, and the broad digitus are diagnostic for I. bohartiana sp. nov. (aedeagus lobes pointed apically in I. leucocheiloides).
Description of holotype female. Body (Fig. 13). Length: 8.2 mm. Coloration: head primarily green blue, with faint bluish highlights on vertex; F1 brownish; mesosoma metallic green, with purplish blue highlights on dorsum, especially on pronotum and mesoscutum (Fig. 16); metasoma metallic green blue; T3 with blue highlights dorsally, without whitish spot basolaterally; wing membrane dark brown, with blackish veins; femora and tibiae greenish; tarsi brown, basitarsi brownish green. Head: with well-developed TFC forming a rectangular enclosure, slightly interrupted medially (Fig. 14); F1 slightly longer than broad, 1.2× as long as F2; scapal basin with sparse silvery pubescence laterally, with shiny polished narrow stripe medially; malar and subantennal spaces very short, less than 0.5 MOD; lower genal space bisected by small irregular carina. Mesosoma: fore femur with distinct flattened area on outer surface of distal margin (Fig. 17), diameter of distal area subequal to diameter of proximal area; distinct erect setae on median tibia; hind tibia with some long setae among short ones; fore wing with short M distal to discoidal cell (as in Fig. 190); R1 strongly reduced, just slightly indicated (as in Fig. 145), medial cell with sparse setae distally; dorsal surface of pronotum wider than head (Fig. 16); lower lateral pronotal surface smooth anteriorly, separated from the posterior surface by a transverse ridge (Fig. 17); metanotum rounded, without differentiated surface; mesopleural lower posterior margin strongly carinate, with distinct well-separated tooth-like projections. Metasoma: T3 with four acute distal teeth (Fig. 15), pit row represented by deep foveae, prepit swelling low, sloping gently; S2 spots medium-sized, nearly reaching each other medially (Fig. 18); metasomal borders with distinct gold brownish setae. Punctation: fore femur with coarse punctures on outer surface (Fig. 17); largest punctures on T1, mesopleuron and metanotum; dorsum of T3 with shallow, well-separated punctures, shiny interspaces.
Male. Same as female, except for the characteristic shape of S2 spots as shown in Fig. 18; ventral surface of head and femora with long silvery setae; broad dark band occupying much of the dorsum of meso- and metasoma; T3 with narrow lateral whitish spot. Genital capsule (Fig. 19): cuspis as long as gonostylus; gonostylus wider than cuspis basally; digitus broad and round apically, slightly shorter than cuspis; cuspis and gonostylus setose apically; aedeagus lobes smooth, rounded, blunt apically.
Variation. Despite the disjointed geographical records, specimens are just divergent on whitish spot of lateral surfaces of T3. In all other diagnostic features the specimens are identical. Additionally, the specimens collected in Brazil: Minas Gerais, Marliéria and São Paulo, Boraceia (RPSP and UFES), are slightly shorter than holotype (7.9 mm vs. 8.2 mm).
Etymology. The species is named in honor of Richard Bohart, a talented entomologist and eminent taxonomist of Aculeata wasps.
Host. Unknown.
Distribution. Brazil (MG, SP); Costa Rica (Heredia) (Fig. 20).
Remarks. Ipsiura bohartiana Lucena sp. nov. is easily distinguished from other Ipsiura species meanly by the subrectangular TFC, angulate laterally, fore femur with remarkable flattened area on distal margin and, bisected lower genal area. Furthermore, the aedeagus lobes rounded and blunt apically, and the broad, round digitus, are diagnostic for I. bohartiana sp. nov..
