Ipsiura pilifrons ( Cameron, 1888)

( Figs 163–167 )

Chrysis pilifrons Cameron, 1888: 465 . Holotype Ƌ [examined by photos]: PANAMA ( BMNH).

Chrysis stenops Mocsáry, 1889 . Lectotype ♀ [not examined]: MEXICO: Tampico. Designed by Bohart, in Kimsey & Bohart (1991: 511). Synonymized by Kimsey & Bohart (1991: 511).

Neochrysis (Ipsiura) pilifrons: Bohart 1966: 142 .

Ipsiura pilifrons: Bohart 1985: 711 .

Diagnosis. Ipsiura pilifrons most closely resembles I. oaxacae Bohart and I. genbergi (Dahlbom) . It can be distinguished from these species by the T3 with six acute distal teeth (broadly obtuse in I. oaxacae ), and without lateral whitish spot (spot present in I. genbergi ). Additionally, I. pilifrons can be distinguished from other Ipsiura species by: TFC interrupted medially, with a well-marked secondary lateral facial carina; T3 without prepit swelling, pit row obsolescent, partially covered by anterior crease, and shape of S2 spots ( Fig. 166 ).

Male description. Body ( Fig. 163 ). Length: 6.3 mm. Coloration: head predominantly green, with faint dark green highlights on vertex; F1 green, F2 greenish brown; mesosoma metallic green, with faint purplish highlights on dorsum, especially of pronotum and mesoscutum; metasoma metallic green, with faint transverse purplish blue stripes on dorsum of T1 and T2, bluish highlights on T3, without lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae greenish; tarsi brown, meso- and hind basitarsi bluish green. Head: TFC enclosing the median ocellus, widely interrupted medially ( Fig. 164 ); secondary lateral facial carina clearly marked; F1 longer than broad, 1.3× as long as F2; scapal basin densely covered with silvery pubescence. Mesosoma: fore femur without flattened area or ventral tooth-like projection on outer surface of distal margin, diameter of distal area about one-half of diameter of proximal area; 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 almost impunctate anteriorly, with distinct posterior area delimited by transverse ridge; metanotum rounded, slightly raised posteriorly, not projecting above propodeal surface in lateral view; mesopleural lower posterior margin carinate, with indistinct tooth-like projections. Metasoma: T3 with six acute distal teeth ( Fig. 165 ), pit row partially covered by anterior crease, without prepit swelling; S2 spots medium-sized, weakly separated medially ( Fig. 166 ). Punctation: outer surface of fore femur impunctate; largest punctures on T1, mesopleuron and metanotum; T3 with definite, shallow punctures.

Female. Same as male, except for the characteristic shape of S2 spots as shown in Fig. 166 .

Variation. Body length 6.3–7.9 mm.
