Docalidia longiuscula , sp. nov.

(Plate IIIE, Figs. 167–175 )

Length. Male 8.00 mm., female unknown.

External morphology. Large robust species. General color of dorsum dark brown to black with ivory markings; forewings black basally to brown apically, with 2 broad, irregularly shaped, pale ivory, transverse bands, one subbasal, one subapical, veins with small ivory spots; mesonotum and pronotum black; crown yellow; eyes dark brown (Plate IIIE); face yellow with black longitudinal band below eyes.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, slightly narrower than eye, foveate medially, lateral margins convergent basally; pronotum about 1/3 longer than crown, surface bullated; mesonotum large, about twice as long as pronotum; forewings long, broad, venation typical; clypeus long, broad, lateral margins broadly convex; median longitudinal carina prominent; clypellus about 1/3 as long as clypeus, median longitudinal ridge from base to near apex.

Male genitalia. Pygofer in lateral view narrowly triangulate, caudodorsal process long, sharply pointed apically, caudoventral process very long, narrow, extended to apex of caudodorsal process, caudal margin lobed below base of caudodorsal process ( Fig. 167 ); segment X long, narrow with narrow ventral process ( Fig. 168 ); right subgenital plate, long, moderately broad, tapered distally, glabrous ( Fig. 169 ); style very long, longer than aedeagus, narrow, apophysis sinuate, with 2 robust spines in distal half ( Figs. 170, 171 ); aedeagus long, shaft narrow throughout, ventral process absent, gonopore subapical ( Figs. 172, 173 ); connective broadly Y-shaped, membrane absent, median ridge extending beyond anterior margin of arms, stem long, narrow ( Fig. 174 ); dorsal connective moderately long, plate like in dorsal view ( Fig. 175 ).

Material examined. Holotype male. ECUADOR: Orellana Transect Ent., 1 km. S. Onkone Gare Camp, 220m., Reserva Etnica Waorani, 0º39’10’’S 76º26’00’’ W., 21-VI-1994, T. C. Erwin et al, fogging Terre Firma forest ( NMNH).

Etymology. The name is descriptive for the long caudoventral pygofer process, style, aedeagus and subgenital plate.

Remarks. D. longiuscula has very long, narrow caudoventral processes of the pygofer, and long aedeagus and style which will separate the species from all others known in the genus. The style is unique with 2 robust, widely separated spines on the apical half.
