sp. nov.

Docalidia longiuscula   , sp. nov.

(Plate IIIE, Figs. 167–175 View FIGURES 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 View FIGURES 167–175 ); segment X long, narrow with narrow ventral process ( Fig. 168 View FIGURES 167–175 ); right subgenital plate, long, moderately broad, tapered distally, glabrous ( Fig. 169 View FIGURES 167–175 ); style very long, longer than aedeagus, narrow, apophysis sinuate, with 2 robust spines in distal half ( Figs. 170, 171 View FIGURES 167–175 ); aedeagus long, shaft narrow throughout, ventral process absent, gonopore subapical ( Figs. 172, 173 View FIGURES 167–175 ); connective broadly Y-shaped, membrane absent, median ridge extending beyond anterior margin of arms, stem long, narrow ( Fig. 174 View FIGURES 167–175 ); dorsal connective moderately long, plate like in dorsal view ( Fig. 175 View FIGURES 167–175 ).

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). GoogleMaps  

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.
