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).
