Ipsiura bisulcata ( Ducke, 1902) 

( Figs 7–12View FIGURES 7 – 12)

Chrysis bisulcata Ducke, 1902: 100  . Syntypes 2♀ [not examined]: BRAZIL: Pará, 14.ix.1901, 19.x.1901 A. Ducke (repository unknown). 

Neochrysis (Ipsiura) bisulcata: Kimsey & Bohart 1981: 78  . Ipsiura bisulcata: Bohart 1985: 711  .

Diagnosis. Ipsiura bisulcata  most closely resembles I. klugi (Dahlbom)  , I. prolixa Bohart  and I. longiventris (Ducke)  . It can be distinguished from these and other Ipsiura  species by the following combination of characters: broad upper genal space (much narrower in similar species, especially I. longiventris  ); obtuse lateral teeth on T3 (acute teeth in I. klugi  , I. prolixa  and I. longiventris  ); metanotum rounded (strongly cristate in I. klugi  and serriform in I. prolixa  ); subsquare-shaped and medium-sized S2 spots (S2 spots rounded and large in I. longiventris  , and ovoid in I. prolixa  and I. klugi  ). Additionally, the bilobate cuspis is unique in I. bisulcata  .

Female description. Body ( Fig. 7View FIGURES 7 – 12). Length: 7.6 mm. Coloration: head predominantly green; F1 brownish green; mesosoma metallic green, with faint bluish highlights dorsally, particularly on pronotum; metasoma metallic green, with whitish spot laterally on T3; wing membrane light brown, with brown veins; femora and tibiae greenish; tarsomeres brown, only hind basitarsus green. Head: TFC enclosing the median ocellus, interrupted medially ( Fig. 8View FIGURES 7 – 12); upper genal space broad, more than 2.5× MOD long; F1 longer than broad, about 1.2× as long as F2; scapal basin covered with silvery pubescence. Mesosoma: fore femur 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. 190View FIGURE 190); dorsal surface of pronotum wider than head; lower lateral pronotal surface smooth, without distinct posterior area delimited by transverse ridge; metanotum rounded, without differentiated surface; lower posterior margin delimited by carina, with well-separated tooth-like projections. Metasoma: T3 with six distal teeth, the lateral teeth obtuse ( Fig. 9View FIGURES 7 – 12), pit row indicated by long and shallow foveae, prepit swelling low, sloping gently; S2 spots medium-sized, touching medially ( Fig. 10View FIGURES 7 – 12). Punctation: fore femur with coarse punctures on outer surface; largest punctures on T1, mesopleuron and metanotum; T2 posteromedially and T3 prepit swelling with shallow and well-separated punctures.

Male. Same as female, except for the characteristic shape of S2 spots as shown in Fig. 10View FIGURES 7 – 12, widely separated medially; broad dark band occupying much of the dorsum of meso- and metasoma. Genital capsule ( Fig. 11View FIGURES 7 – 12): cuspis as long as gonostylus; digitus bilobate, slightly shorter than cuspis, basally narrower than apically; apices of gonostylus and cuspis with long hairs; aedeagus blunt apically, lobes elaborate ( Fig. 11View FIGURES 7 – 12).

Variation. Body length 7.6–8.4 mm.

Host. Unknown.

Distribution. Brazil (AC, AM, PA) ( Fig. 12View FIGURES 7 – 12).

Taxonomic remarks. There are no indications in the original description of species ( Ducke 1902) nor in the catalogue of Ducke (1913) about the repository of I. bisulcata  , and we have been unable to locate the types. Despite the lost type specimens, redescription of this species was possible based on reliably identified specimens by Ducke, housed in the MPEG and BME collections.

Material examined. BRAZIL: Acre, Senador Guiomard , Res. Catuaba 19.xi.2002, 1Ƌ, coll. E.F. Morato [BME]  . Amazonas, Manicoré Cachoeira ix.2004, 1 ♀, coll. Silva & Pena [ INPA]  . Pará, Óbidos 01.i.1907, 1♀, coll. Ducke, A. [ MPEG]  . Óbidos 07.i.1905, 1♀, coll. Ducke, A. [BME]. Óbidos 03.i.1907, 1♀, coll. Ducke, A. [BME]. 

Comments. The redescription above is based on a female from Brazil: Pará, Óbidos.
