Ipsiura leucobasis ( Mocsáry, 1913)

( Figs 96–101 )

Chrysis leucobasis Mocsáry, 1913: 12 . Holotype ♀ [examined by photos]: BRAZIL: Santa Cruz (HNHM). Neochrysis (Ipsiura) leucobasis: Bohart 1966: 142 .

Ipsiura leucobasis: Bohart 1985: 711 .

Diagnosis. Ipsiura leucobasis most closely resembles I. boliviana Bohart. Both species have six irregular distal teeth on T3, pit row obsolescent, except for small lateral pits, females with conspicuous golden hairs on S2 and S3, and T3 with narrow basolateral whitish spot. Ipsiura leucobasis is generally shorter than I. boliviana (9 mm vs. 11 mm), narrow upper genal space (shorter than 1.2× MOD long) and lacking the shallow depression on the median area of pronotum, which is characteristic of I. boliviana .

Female description. Body ( Fig. 96 ). Length: 9 mm. Coloration: head predominantly green blue, with faint purple highlights on vertex; F1 brown; mesosoma metallic green, with purplish blue highlights on dorsum, particularly on pronotum and mesoscutum; metasoma metallic greenish blue, with transverse purplish stripes on dorsum of T2 and T1; T3 with narrow lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae green; tarsi brownish, hind basitarsus brownish green. Head: TFC enclosing the median ocellus, roundshaped but slightly interrupted medially ( Fig. 97 ); upper genal space narrow, about 1.2× MOD long; F1 longer than broad, 1.3× as long as F2; scapal basin with dense silvery pubescence laterally, with narrow polished stripe medially. 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; hind tibia with some long setae among short ones; fore wing with short M distal to discoidal cell, R1 shorter than stigma (as in Fig. 190 ); dorsal surface of pronotum wider than head; lower lateral pronotal surface smooth, irregularly punctate anteriorly, without distinct posterior area delimited by transverse ridge; metanotum rounded, without differentiated surface; mesopleural lower posterior margin carinate, with distinct tooth-like projections. Metasoma: T3 with six irregular distal teeth ( Fig. 98 ), pit row obsolescent, indicated by small lateral pits, with distinct prepit swelling but sloping gently; S2 spots medium-sized, nearly reaching each other medially ( Fig. 99 ). Punctation: fore femur impunctate on outer surface; largest punctures on T1, mesopleuron and metanotum; T3 with shallow and separated punctures.

Male. Same as female except for the characteristic shape of S2 spots as shown in Fig. 99 , and without long hairs on S2 and S3. Genital capsule ( Fig. 100 ): aedeagus lobes broad, elaborate, strongly convergent apically; digitus narrow, slightly shorter than cuspis, broad apically, clavate; gonostylus and cuspis setose apically.

Variation. Body length 7.8–9.2 mm.

Host. Unknown.

Distribution. Argentina (Corrientes); Brazil (AM, ES, MG, PR, SC, SP); Costa Rica (Puntarenas); Panama (Colon); Paraguay (Caaguazú, Guairá, San Pedro) ( Fig. 101 ).
