Diagnosis. Ipsiura obidensis most closely resembles I. lata Bohart. It can be distinguished from I. lata by the metanotum irregularly cristate medially (strongly cristate in I. lata ), and the TFC closed medially, much broader than long (slightly interrupted and longer than broad in I. lata ). Ipsiura obidensis can be distinguished from other Ipsiura species by the following combination of characters: T3 with six distal teeth, the lateral teeth usually are strongly obtuse, prepit swelling sloping gently, and large lateral whitish spots; large S2 spots, that touching medially; scapal basin densely covered with silvery pubescence and the TFC forming broad enclosure, and closed medially.

Male description. Body ( Fig. 157 ). Length: 6.2 mm. Coloration: head predominantly bluish green, with dark purple highlights on vertex; F1 bluish green, F2 brownish green; mesosoma metallic blue, with dark purple bands on dorsum, particularly on pronotum and mesoscutum; metasoma metallic blue, with transverse dark purple stripes on dorsum of T1 and T2; T3 with purplish highlights, and large lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae bluish; tarsi brown, hind basitarsus brownish blue. Head: TFC enclosing the median ocellus, closed medially, much broader than long ( Fig. 158 ); F1 longer than broad, 1.2× as long as F2; scapal basin densely covered with silvery pubescence. Mesosoma: fore femur with discrete flattened area on outer surface of distal margin, without ventral tooth-like projection; fore wing with short M distal to discoidal cell, R1 shorter than stigma (e.g. Fig. 190 ); dorsal surface of pronotum wider than head; lower lateral pronotal surface smooth, punctate anteriorly, without distinct posterior area delimited by transverse ridge; metanotum irregularly serrate to cristate medially; mesopleural lower posterior margin carinate, with distinct close together tooth-like projections. Metasoma: T3 with six distal teeth, the lateral teeth are broadly obtuse ( Fig. 159 ), pit row exposed, represented by distinct, small foveae, prepit swelling sloping gently; S2 spots large, touching medially ( Fig. 160 ). Punctation: outer surface of fore femur punctate, with definite sparse punctures; largest punctures on T1, mesopleuron and metanotum. Genital capsule ( Fig. 161 ): aedeagus longer than gonostylus and cuspis; cuspis shorter than gonostylus, broader basally than apically; digitus very narrow, shorter than cuspis, strongly clavate; gonostylus and cuspis with short setae apically.

Female. Same as male, except for the characteristic shape of S2 spots as shown in Fig. 160 , and usually shaperst T3 lateral teeth.

Variation. The body coloration varies from the usual blue to green, especially in specimens from northeast Brazil: Rio Grande do Norte, Paraíba and Bahia. Body length 6.1–6.5 mm.

Hosts. Unknown.

Distribution. Argentina (Salta, Santa Fe); Brazil (AM, BA, CE, MA, MG, PA, RN, SP); Paraguay ( San Pedro, Villarica) ( Fig. 162 ).
