Boliviela caverna , sp. nov.

( Plate 1C, Figs. 17–24)

Length. Male 8.50 mm., female unknown.

External morphology. Moderately large, slender species. General color black throughout with numerous very small yellow spots on veins and one large yellow marking subapically on forewings; eyes grey; face dark brown, speckled with small yellow spots (Plate IC). Head significantly narrower than pronotum, anterior margin acutely angled; crown narrower than width of eyes, produced distally about ¼ distance of entire median length, lateral margins parallel, slightly carinate, disk depressed; pronotum with median length less than length of crown, surface sparsely bullated; mesonotum about equal in length to pronotum; forewings typical; clypeus elongate, broad in basal half, narrowed in apical half; clypellus short, about ¼ as long as clypeus, base very broad, inflated, lateral margins constricted medially.

Male genitalia. Pygofer narrow with 2 distinct caudal processes, caudodorsal process long, narrow, curved near middle, caudoventral process very long, broad in basal 1/3, attenuated in apical 2/3, apex sharply pointed ( Fig. 17); right subgenital plate long, narrow, outer lateral margin expanded in distal ½, sparsely pilose ( Fig. 18); right style long, narrow in middle 2/3, apex expanded in distal ¼ ( Figs. 19, 20); aedeagus long, inflated along middle half in dorsal and lateral views, cavernate at middle with distal flange in lateral view, tubular, curved in apical 2/6, apical 1/6 digitate, sinuate and directed caudodorsally in lateral view, gonopore subapical ( Figs. 21, 22); connective small, Y-shaped, stem very short ( Fig. 23); dorsal connective long, narrow, bifurcate basally ( Fig. 24), attached basally to dorso-subbasal shaft of aedeagus, not encircling shaft ( Fig. 21).

Material examined. Holotype male. COLOMBIA: Huila, PNN Cueva de los Cuacharos, Borde de Rio Suaza , 1º 37’N.– 76º6’W., 2020 m., 28 Nov 01–11 Dec 01, M. 2542, Malaise, D. Campos ( IAHC) . Paratype, 1 male, Huila, PNN Cueva de los Cuachoros, Cabana Cedros , 1º37’N.– 76º6’W., 1950 m., 22 Nov 01–12 Feb 01, M. 2526, Malaise, D. Campos ( MLBM) .

Etymology. The name is descriptive for a large excavation in the middle of the inflated portion of the aedeagal shaft.

Remarks. This species is similar in male genitalia features to B. inflata DeLong and can be separated by the larger size, the excavated aedeagal shaft and the short basal bifurcation of the dorsal apodeme.
