Docalidia longula

sp. nov.

Docalidia longula   , sp. nov.

(Plate IIIF, Figures 176–183 View FIGURES 176–183 )

Length. Male 8.00–8.20 mm., female unknown.

External morphology. Large, robust species. General color of dorsum unicolorous brown, except for pronotum, mesonotum, black; eyes suffused with brown markings (Plate IIIF).

Head broad, distinctly narrower than pronotum, anterior margin broadly rounded; crown broad, about as wide as eye, slightly carinate laterally, slightly divergent basally; eyes large, elongate ovoid; pronotum large, about ¼ times longer than crown, inflated medially; mesonotum large, about 1/3 longer than pronotum; forewings long, broad, venation typical; clypeus broad, lateral margins tapered distally, truncate at transclypeal suture; median longitudinal carina prominent, clypellus about 1/3 as long as clypeus, lateral margins flared distally.

Male genitalia. Pygofer in lateral view large, triangulate, caudodorsal process robust, caudoventral process reduced to lenticular lobe below base of caudodorsal process ( Fig. 176 View FIGURES 176–183 ); right subgenital plate long, very broad, setose in basal 1/3 and along ½ of inner lateral margin ( Fig. 177 View FIGURES 176–183 ); right style long, longer than aedeagus, robust, with row of stout setae from middle to near apex ( Figs. 178, 179 View FIGURES 176–183 ); aedeagus long, tubular, with very long subapical ventral process, gonopore near middle, exiting ventrally ( Figs. 180, 181 View FIGURES 176–183 ); connective T-shaped, arms narrow, membrane absent, medial ridge extending beyond anterior margin or arms, stem long, bulbous apically, with small medial process ( Fig. 182 View FIGURES 176–183 ); dorsal connective long, plate like, broad basally, tapered distally in dorsal view ( Fig. 183 View FIGURES 176–183 ).

Material examined. Holotype male. PERU: Madre de Dios, Rio Tambopata Res. , 30 km. (air), SW Pto. Maldonado, 290 m., 12º50’S. 69º20’W., 10-XI-1982, insect flight trap, R. C. Wilkerson ( NMNH) GoogleMaps   . Paratype. 1 male, same data as holotype, except 20-29-X-1982 ( MLBM) GoogleMaps   .

Etymology. The name is descriptive for the long ventral process on the aedeagus.

Remarks. From D. gracilitas ( Nielson, 1986e:759)   , longula   , sp. nov. can be distinguished by absence of the ventral process of segment X, by the broader subgenital plate with setae on the basal half, and by the row of stylar setae which does not reach the apex of the apophysis.
