Ipsiura oaxacae Bohart, 1985

(Figs 147–151)

Ipsiura oaxacae Bohart, 1985: 718 . Holotype Ƌ [examined]: MEXICO : Oaxaca, Matias Romero (BME). Neochrysis (Ipsiura) dissedidentata Linsenmaier, 1985 . Holotype ♀ [not examined]: BRAZIL (NMLS). Synonymized by Kimsey & Bohart (1991: 510).

Neochrysis (Ipsiura) oaxacae: Linsenmaier 1997: 267 .

Diagnosis. Ipsiura oaxacae most closely resembles I. pilifrons (Cameron) . It can be distinguished from I. pilifrons by the obtuse T3 distal teeth and the shape of S2 spots (Figs 149, 150). Ipsiura oaxacae is also readily distinguished from other Ipsiura species by the following combination of characters: pit row obsolescent, with small pits marked laterally; T3 without basolateral whitish spot neither distinct prepit swelling dorsally; S2 spots widely separated medially and TFC interrupted medially.

Female description. Body (Fig. 147). Length: 7 mm. Coloration: head predominantly green blue, with faint purplish highlights on vertex; F1 bluish green; mesosoma metallic green blue, with faint purplish highlights on dorsum of pronotum and mesoscutum; metasoma metallic bluish green, with transverse bluish purple stripes on dorsum of T1 and T2; T3 without lateral whitish spot; wing membrane light brown, with brown veins; femora and tibiae bluish green; tarsi brown, hind basitarsus green; fore- and meso basitarsi brownish green. Head: TFC enclosing the median ocellus, widely interrupted medially (Fig. 148), with lateral secondary facial carina well 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 smooth, with indistinct posterior area delimited by faint transverse ridge; metanotum rounded, without differentiated surface; mesopleural lower posterior margin carinate, with indistinct tooth-like projections. Metasoma: T3 with six obtuse distal teeth (Fig. 149), pit row obsolescent, with small lateral pits, partially obscured by anterior crease, prepit swelling absent; S2 spots small, widely separated medially (Fig. 150). Punctation: fore femur impunctate on outer surface; largest punctures on T1, mesopleuron and metanotum.

Male. Same as female, except for the characteristic shape of S2 spots as shown in Fig. 150.

Hosts. Unknown.

Distribution. Brazil (SC); Mexico (Oaxaca) (Fig. 151).

Remarks. There are only two known specimens of I. oaxacae, one collected in Mexico, Oaxaca and a female from Santa Catarina, Brazil. Despite the disjointed geographic records, they agree in all specific characteristics.

Material examined. MEXICO: Oaxaca, 23 mi south Matias Romero, viii.14.1963, coll. F.D. Parker & L.A. Stange / Holotype Ƌ [BME] . BRAZIL: Santa Catarina, Nova Teutonia ii.1968, 1 ♀, coll. Fritz Plaumann [BME].

Comments. The redescription above is based on a female from Brazil: Santa Catarina, Nova Teutonia.
