Collasuyusana bifurcata , sp. nov.

( Plate 1I, Figs. 61–68)

Length: Male 7.00 mm., female 8.60–8.80 mm.

External morphology. Slender species. General color dark brown to black with numerous small yellow spots on veins of forewings and 2 large irregular shaped markings on costa; head and face dark brown (Plate II). Head distinctly narrower than pronotum, anterior margin obtusely angulate, crown broad, about as wide as width of eyes, produced distally about 1/3 of its entire median length, lateral margins slightly carinate, disk depressed medially; eyes large, occupying about 2/3 of entire dorsal area of head, semiglobular; pronotum about as long as median length of crown, surface bullated; mesonotum about as long as median length of pronotum; forewings typical; clypeus elongate, broader basally than apically; clypellus short, about 1/3 as long and clypeus, very broad and inflated basally, narrowed distally.

Male genitalia. Pygofer narrow with 2 caudal processes, caudodorsal process long, broad, with bifid apex, caudoventral process prominent, very long, narrow, extending beyond apex of caudodorsal lobe ( Fig. 61); right subgenital plate long, narrow, outer lateral margin expanded, sparsely setose ( Fig. 62); style long, nearly as long as aedeagus, distal ½ slightly enlarged with longitudinal striations ( Figs. 63, 64); aedeagus long, tubular, base recurved at right angle, prominent spine apically, directed caudally, gonopore subapical ( Figs. 65, 66); connective small, Y-shaped, stem very short ( Fig. 67); dorsal connective with basal arms enclosing shaft of aedeagus, arms attached basally to subbasal ventral spur of aedeagus ( Figs. 65, 66).

Female genitalia. Seventh sternite large, nearly twice as long as penultimate sternite, caudal margin broadly convex, slightly indentate medially ( Fig. 68).

Paratypes. 4 males, same data as holotype ( MLBM, UK) ; 7 males, Huila , PNN Cueva de los Guacharos, Cabaña Cedros, 1º 37N .– 76º 6’W., 2100 m., Malaise , 2/4/ 2002 – 2/18/2002, C. Cortes, leg. M. 3036 ( IAHC) ; 7 males, 3 females, Valle del Cauca , PNN Farallones de Cali Cgto. La Meseta, 3º34’N.– 76º 40’ W., 1960 m., Malaise, 27/08/2003 – 10/09/2003, S. Sarria & M. Losso leg., (specimen numbers, M. 4542, 4544, 4545, 4546, 4548, 4549, 4551, 4552, some duplications) ( IAHC) .

Etymology. The name is descriptive for the apical, bifid caudodorsal process of the pygofer.

Remarks. C. bifurcata , sp. nov. is nearest to C. lanceolata , sp. nov. and can be easily separated from all known species by the apical, bifurcate caudodorsal process of the pygofer.
