Type material.

Holotype male, PERU: Ancash Region, 4 km NW Carhuaz, Auquipampa, 9°16.91'S 77°39.23'W, 3640 m, 17-18 September 2009, coll. ME Irwin (1212) [USML].

Diagnosis.

Pygofer with caudodorsal margin produced as a curved, tapered process, caudoventral processes subbasally, apex slightly enlarged in lateral aspect, extended beyond caudodorsal processes; aedeagus large and broad, lateral edge rolled ventrally, tapered to compressed apical 1/4 in lateral view, apex curved dorsally, gonopore subapical on lateral surface, dorsal connective bifurcate at base, enclosing aedeagus subbasally; style reaching to apex of aedeagus, needle-like with apical third enlarged, corrugated, a small process at subapex; subgenital plate with dense hair-like setae at apical half.

Description.

Measurements. Male. Body length 8.01 mm; crown length 0.88 mm; width between eyes 0.71 mm; eye width 0.69 mm; clypeus length 1.57 mm; clypellus length 1.00 mm; pronotum length 0.94 mm; mesonotum + scutellum length 1.15 mm. Female unknown.

External morphology. Medium species, body slender. General color dark brown. Crown, pronotum and mesonotum deep brown with trivial light-brown spots, some gathered in patches; eyes piceous; forewing brown with pellucid markings, veins dark brown with pale spots (Figs 10, 11). Face fuscous with dull yellow tiny spots (Figure 12).

Anterior margin of head obtusely angular. Crown midlength produced distally approx. 1⁄3 of entire length; area between eyes approx. as wide as eye width, surface without wrinkles, elevated above level of eyes; lateral margins parallel, slightly carinate, surpassing anterior margin of eyes distally. Medial length of pronotum longer than crown but shorter than mesonotum (Figure 10). Clypeus long, narrow, lateral margins convex basally; clypellus broad, maximum width approx. equal to midlength, base inflated, lateral margins constricted medially, tapered apically (Figure 12).

Male genitalia. Pygofer short, caudodorsal margin produced as a curved, tapered process (Figure 14), basally with a triangular plate on each side, caudoventral processes subbasally, very long, apex slightly enlarged in lateral aspect, extended beyond caudodorsal processes; segment X broad and long with lateral margins parallel in ventral view (Figure 13). Aedeagus large and broad, lateral edge rolled ventrally, tapered to compressed apical 1/4 in lateral view, apex curved dorsally; gonopore subapical on lateral surface; dorsal connective bifurcate at base, enclosing aedeagus subbasally (Figs 15, 16). Connective very small, Y-shaped, anterior stem very short (Figure 19). Style long, reaching to apex of aedeagus, needle-like with apical third enlarged, corrugated, a small process at subapex (Figs 17, 18). Subgenital plate narrow, outer lateral margin convex at apical third, tapered to apex, dense hair-like setae at apical half (Figure 20).

Etymology.

The specific epithet is descriptive of the expanded aedeagus in dorsal and lateral views.

Remarks.

The new species keys to Collasuyusana Nielson in Nielson (2011), but its aedeagal shaft is atypical of this genus. We therefore provisionally assign the species to Boliviela based on the inflated aedeagal shaft, despite the dorsal connective being atypical of this genus. According to Prof. Nielson, retired faculty of Brigham Young University (pers. com.) the aedeagus holds historically a higher diagnostic value than the dorsal connective.
