Ipsiura irwini Bohart, 1985 

( Figs 78–83View FIGURES 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. 82View FIGURES 78 – 83).

Male description. Body ( Fig. 78View FIGURES 78 – 83). 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. 79View FIGURES 78 – 83); 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. 190View FIGURE 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. 80View FIGURES 78 – 83), pit row completely exposed, with well-definite foveae, prepit swelling protruding; S2 spots large, touching medially ( Fig. 81View FIGURES 78 – 83). 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. 82View FIGURES 78 – 83): 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. 81View FIGURES 78 – 83.

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. 83View FIGURES 78 – 83).
