Ipsiura irwini Bohart, 1985

( Figs 78–83 )

Ipsiura irwini Bohart, 1985: 715 . Holotype Ƌ [examined]: EL SALVADOR, 4 mi N. Quezaltepeque (BME).

Diagnosis. Ipsiura irwini most closely resembles I. lata Bohart , I. fritzi Bohart and I. obidensis (Ducke) . It can be readily distinguished from those as well as from other Ipsiura species by the following combination of characters: T3 without lateral whitish spot (present in I. fritzi , I. lata and I. obidensis ), with six acute distal teeth (the lateral teeth are sometimes obtuse in I. obidensis ); metanotum cristate medially (irregularly punctate in I. fritzi and faintly serriform in I. obidensis ); fore femur without definite punctures on outer surface (coarsely punctate in I. lata and I. obidensis ); TFC interrupted medially (complete in I. lata and I. obidensis ) and the lower posterior mesopleural margin with two small close together tooth-like projections (well-separated in I. lata ). Additionally, the shape of aedeagus lobes is diagnostic for I. irwini ( Fig. 82 ).

Male description. Body ( Fig. 78 ). Length: 7.6 mm. Coloration: head predominantly green, with faint dark bluish highlights on vertex; F1 brownish green; mesosoma metallic green, with faint dark bluish highlights on dorsum, especially of pronotum and mesoscutum; metasoma metallic green blue, with distinct transverse purple stripes on dorsum of T1 and T2; T3 with blue highlights, without lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae greenish; tarsi brownish. Head: TFC interrupted medially ( Fig. 79 ); scapal basin densely covered with silvery pubescence; F1 longer than broad, 1.3× as long as F2. Mesosoma: fore femur with faint ventral angle on distal margin, discrete flattened area on outer surface of distal margin, diameter of distal area subequal to 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 irregularly punctate anteriorly, without distinct posterior area delimited by transverse ridge; metanotum raised medially, slightly cristate; mesopleural lower posterior margin carinate, with two small close together tooth-like projections. Metasoma: T3 with six acute distal teeth ( Fig. 80 ), pit row completely exposed, with well-definite foveae, prepit swelling protruding; S2 spots large, touching medially ( Fig. 81 ). Punctation: outer surface of fore femur impunctate or with only tiny sparse punctures; largest punctures on T1, mesopleuron and metanotum; well-definite punctures on dorsal surface of head and mesosoma, shallow on T2 and T3. Genital capsule ( Fig. 82 ): cuspis as long as gonostylus; digitus long, very narrow, subequal to cuspis in size, pointed, clavate apically; gonostylus as broad as cuspis basally; gonostylus and cuspis with short setae apically; aedeagus with sinuouse margins, lobes elaborate, acute apically.

Female. Same as male except for the characteristic shape of S2 spots as shown in Fig. 81 .

Variation. Body length 7.6–7.9 mm.

Hosts. Unknown.

Distribution. Costa Rica (Guanacaste); El Salvador (La Libertad); Mexico (Colima, Jalisco, Tamaulipas, Veracruz); USA (Texas) ( Fig. 83 ).
