Ipsiura covillei Bohart, 1985

( Figs 40–46 )

Ipsiura covillei Bohart, 1985: 714 . Holotype Ƌ [examined]: COSTA RICA: La Selva , Heredia, 4 km SE Puerto Viejo (BME).

Diagnosis. This species most closely resembles Ipsiura genbergi (Dahlbom) , I. oaxacae Bohart and I. frieseana (Ducke) . Ipsiura covillei is readily distinguished from these and other Ipsiura species with six distal teeth on T3, by the distinctive characters of the males: orange flagellomeres (brownish in the most species), long plumose hairs beneath flagellomeres and legs (without long hairs in most species), irregular and weakly developed pronotal carina (regular and strongly protruding in most species), and the unusual long and elaborate aedeagus lobes. Females can be easily distinguished by the following combination of characters: T3 with lateral whitish spot (absent in I. oaxacae ), pit row partially obscured by anterior crease (pit row absent in I. frieseana ); metanotum rounded (slightly elevated posteriorly in I. genbergi ); S2 spots widely separated medially (close together in most species); and scapal basin with medial polished stripe (weak or covered by silvery pubescence in other related species).

Male description. Body ( Fig. 40 ). Length: 5.8 mm. Coloration: head predominantly green, with purplish highlights on vertex; flagellomeres orange; mesosoma metallic green, with broad dark purple band on dorsum, especially on pronotum and mesoscutum ( Fig. 41 ); metasoma metallic green blue, with transverse dark purple stripes on T1 and T2; large lateral whitish spot on T3; wing membrane light, with brown veins; femora and tibiae greenish; tarsi yellow whitish. Head: TFC enclosing the median ocellus, completely opened medially ( Fig.42 ); F1 longer than broad, about 1.4× as long as F2; long plumose hairs beneath of legs and flagellomeres; scapal basin with sparse silvery pubescence laterally, narrow polished stripe medially. Mesosoma: fore femur without flattened area or ventral tooth-like projection on outer surface of distal margin, with tiny ventral projection basally, diameter of distal area about one-half 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 as wide as or slightly wider than head; lower lateral pronotal surface irregularly punctate anteriorly, with distinct posterior area delimited by transverse ridge; lateral pronotal carina irregular, not protruding; metanotum rounded, without differentiated surface; mesopleural lower posterior margin crenate, without tooth-like projections. Metasoma: T3 with six acute distal teeth ( Fig. 43 ), pit row obsolescent, obscured by anterior crease and, without distinct prepit swelling; S2 spots small, round, widely separated medially ( Fig. 44 ). Punctation: fore femur impunctate on outer surface; largest punctures on T1, mesopleuron and metanotum. Genital capsule ( Fig. 45 ): aedeagus lobes elaborate, sharp apically, unusually long, longer than gonostylus and cuspis; cuspis as long as gonostylus, asetose apically, slenderer than gonostylus basally; gonostylus much broader basally than apically, with long hairs distally; digitus acute apically, narrower basally than apically.

Female. Same as male, except for the characteristic shape of S2 spots as shown in Fig. 44 ; without long plumose hairs beneath of legs and flagellomeres; flagellomeres brown; dorsal surfaces of body without broad dark band occupying much of the dorsum of meso-and metasoma.

Host. Species of Trypoxylon (specimen labels; Bohart 1985).

Distribution. Brazil (AM, SP); Costa Rica (Limón, Heredia); Mexico (Tamaulipas, Veracruz); Peru (Jaén); Venezuela (Aragua) ( Fig. 46 ).
