Dialodia brevisetacea , sp. nov.

( Plate 3I, Figs. 194–201)

Length. Male 7.10–7.50 mm; female unknown.

External morphology. Medium size, robust species. General color black with yellow markings, small yellow spots on pronotum; forewings with veins black, cells translucent; mesonotum black with broken yellow stripe on each side of middle; crown black with yellow transverse band on anterior margin; face black, with large yellow semi-oval marking on middle of clypeus, narrow yellow transverse line basally, ocellocular area yellow ( Plate 3I). Head distinctly narrower than pronotum, anterior margin broadly rounded; crown slightly narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiglobular; pronotum about ¼ as long as crown, surface bullated; mesonotum large, nearly 1½ times as long as pronotum; forewings typical; clypeus long, broad anteriorly, slightly tapered basally; clypellus narrow, slightly inflated basomedially, lateral margins constricted medially.

Male genitalia. Pygofer in lateral view narrow, few setae and small lobe caudodorsally ( Fig. 194); right subgenital plate long, constricted medially, setaceous in distal ¼ ( Fig. 195); style in lateral view with apophysis broad medially, curved and narrowed apically ( Fig. 196), in dorsal view corrugated along lateral margin ( Fig. 197); aedeagus long, narrow, tubular except for distal ¼, numerous very short setae on ventral margin near distal ¼, small serrate flange subapically on dorsal margin in lateral view, gonopore cryptic ( Figs. 198, 199); connective narrowly Yshaped, membranous medially, stem moderately long ( Fig. 201); dorsal connective attached to base of aedeagal socle ( Fig. 198), long, narrow plate like ( Fig. 200).

Material examined. Holotype male. COLOMBIA: Huila, PNN Cueva de los Guacharos, Alto el Mirador, 1º38’N.– 76º6’W., 1980 m., Malise, 2/18/2002 – 3/7/2002, F. Quevedo, leg., M.3039 ( IAHC) . Paratypes. 2 males, same data as holotype except Cabaña Cedros, 1º37’N.– 76º6’W., Malaise, 4/27/02–5/5/02, J. Fonseca leg., M.3130 ( IAHC, MLBM) , 1 male, same data as holotype except Malaise, 1/6/02–1/20/02, J. Urbano leg., M.2922 ( UK) .

Etymology. The species name is descriptive for the numerous short setae on the subapical margin of the aedeagus.

Remarks. This species is nearest to D. aviculobata , sp. nov. and can be distinguished by the narrow pygofer and style, medially constricted subgenital plate, the configuration of the aedeagus and narrowed arms of the connective.
