Ipsiura boliviana Bohart, 1985

( Figs 21–25 )

Ipsiura boliviana Bohart, 1985: 711 . Holotype ♀ [examined by photos]: BOLIVIA: Santa Cruz, Puerto Grether (BMNH). Neochrysis (Ipsiura) boliviana: Linsenmaier 1997: 268 .

Diagnosis. Large species (longer than 11 mm). Ipsiura boliviana most closely resembles I. leucobasis (Mocsáry) .

It can be distinguished from I. leucobasis and other Ipsiura species by the combination of the following characters: T3 with six, obtuse, irregular distal teeth (more regular teeth in other Ipsiura species with six distal teeth), pit row obsolescent or obscured by anterior crease (well-developed in other Ipsiura species with six distal teeth) and wide and shallow depression on the median area on dorsum of pronotum (absent in I. leucobasis ).

Female description. Body ( Fig. 21 ). Length: 11.3 mm. Coloration: head predominantly metallic green, with faint bluish highlights on vertex; F1 brownish; mesosoma metallic green, with faint transverse bluish stripes on dorsum, particularly on pronotum and mesoscutum; metasoma metallic green, with transverse purplish blue stripes on T1 and T2, with narrow lateral whitish spot on T3; wing membrane light brown, with brown veins; femora and tibiae green; tarsi brown, hind basitarsus green. Head: TFC enclosing median ocellus, widely interrupted medially ( Fig. 22 ); F1 longer than broad, 1.3× as long as F2; scapal basin covered with sparse silvery pubescence laterally, with broad polished stripe medially. Mesosoma: fore femur without flattened area or tooth-like projection ventrally 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 much wider than head; lower lateral pronotal surface deep, smooth, punctate anteriorly, without distinct posterior area delimited by transverse ridge; pronotum with shallow wide depression medially; metanotum rounded, without differentiated surface; mesopleural lower posterior margin strongly carinate, with distinct tooth-like projections. Metasoma: T3 with six irregular distal teeth ( Fig. 23 ), pit row obsolete, indicated by small obscured lateral pits; prepit swelling strong but sloping gently, marked laterally; S2 spots medium-sized, round, nearly reaching each other medially ( Fig. 24 ); metasomal borders with some long golden setae. Punctation: fore femur punctate on outer surface, sparse and tiny punctures; largest punctures on T1, mesopleuron and metanotum.

Male. Unknown.

Variation. There are just a few specimens of I. boliviana . The most conspicous differences are in body length. Specimens collected in Brazil (Rondônia, Vilhena–DZUP) are shorter than 10.8 mm, on the other hand the holotype and paratype are larger, about 11.1 to 11.3 mm long, respectively.

Host. Unknown.

Distribution. Bolivia (Santa Cruz); Brazil (RO) ( Fig. 25 ).

Remarks. The most similar species in the genus is I. leucobasis . These species share many morphological traits, as the irregular distal teeth, obsolete pit row, shape and size of S2 spots, elongated hairs on S2 and S3 of female and the robust, heavily sclerotized, serrated ovipositor. The shallow depression on the median area of pronotum is diagnostic for I. boliviana . Additionally, the integument of the distal margin of T 3 in I. leucobasis is usually black and noticeably sclerotized. On the other hand in I. boliviana it is totally greenish. The differences in body length (about 10.8–11.3 mm in I. boliviana vs. 7.9–8.4 mm in I. leucobasis ) are also diagnostic.
