Evansolidia gracilitas , sp. nov.

( Plate 4E, Figs. 234–241)

Length. 7.40 mm; female unknown.

External morphology. Moderately large, robust species. General color black and yellow; forewings with yellow veins on mid-clavus, lateral cells yellowish transparent, forming incomplete transverse band, incomplete transverse, yellow transparent band subapically; mesonotum lateral margins yellow, base yellow; pronotum with broken, anterior yellow band, pale yellow markings under anterior margin; crown with yellow lateral margins, yellow longitudinal stripe medially; eyes black; face yellow with broad black longitudinal bands laterally, separated by medial, yellow stripe, extending basally to apex of clypellus ( Plate 4E). Head narrower than pronotum, anterior margin obtusely angulate; crown slightly narrower than width of eyes, produced distally about 1/3 entire length, lateral margins convergent basally, slightly carinate; eyes large, semiglobular; pronotum about ¼ shorter than crown, surface sparsely bullated; mesonotum large, nearly twice as long as pronotum; forewings typical; clypeus long, narrow, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, narrow, inflated basally, lateral margins constricted medially.

Male genitalia. Pygofer in lateral view small, triangulate, small digitate lobe on caudodorsal margin ( Fig. 234); right subgenital plate long, narrow, glabrous ( Fig. 235); style shorter than aedeagus, robust, with small, subapical digitate process in lateral view ( Figs. 236, 237); aedeagus long, tubular with 4 long setae near middle of shaft, 3 smaller setae below middle ( Figs. 238, 239); connective broadly Y-shaped, stem very short, disk between arms membranous, longitudinal ridge medially ( Fig. 240); dorsal connective long, narrow, base slightly expanded ( Fig. 241), attached to base of aedeagal socle ( Fig. 238).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN Amacayacu San Martin, 3º 23’ S.– 70º 6’ W., 150 m., Malaise. 9/16/00–9/24/00, B. Amador, leg., M. 840 ( IAHC).

Etymology. The name is descriptive for relative slender subgenital plates and styles.

Remarks. From E. bispinosa , sp. nov. to which it is most similar, E. gracilatis , sp. nov. can be separated by the greater number of spines and their arrangement on the shaft of the aedeagus.
