Ipsiura duckeana Lucena , sp. nov.

( Figs 47–51 )

Diagnosis. Ipsiura duckeana sp. nov. most closely resembles I. cooperi Bohart. It can be readily distinguished by T3 with four irregular distal teeth (teeth acute and regular in I. cooperi ), without basolateral whitish spot (whitish spot present in I. cooperi ), pit row absent (partially obscured laterally in I. cooperi ) and TFC forming a complete arc (widely interrupted medially in I. cooperi ).

Description of holotype female. Body ( Fig. 47 ). Length: 7.1 mm. Coloration: head green; F1 green, F2 greenish brown; mesosoma metallic green, with bluish highlights on dorsum, particularly of pronotum and mesoscutum ( Fig. 49 ); metasoma primarily green, with distinct purplish transverse stripes on dorsum of T1 and T2; T3 with bluish highlights, without lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae greenish; tarsi brownish, basitarsi brownish green. Head: TFC forming a complete arc, closed medially ( Fig. 48 ); F1 longer than broad, 1.4× as long as F2; scapal basin densely covered with silvery pubescence; malar and subantennal spaces very short, less than 0.5× MOD long. Mesosoma: fore femur without flattened area or ventral tooth-like projection on outer surface of distal margin, diameter of distal area about one-half diameter of proximal area; fore wing with short M distal to discoidal cell, R1 shorter than stigma (as in Fig. 190 ); dorsum of pronotum as wide or slightly narrower than head ( Fig. 49 ); 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 crenate, without distinct carina or tooth-like projections. Metasoma: T3 with four irregular distal teeth ( Fig. 50 ), pit row absent, obscured by anterior crease, prepit swelling absent; S2 spots small, ovoid, widely separated medially ( Fig. 51 ). Punctation: fore femur impunctate on outer surface; largest punctures on T1, mesopleuron and metanotum.

Male. Unknown.
