Etymology
The specific name refers to the type locality, Los Andes.
Diagnosis
Hypandrium of five sclerites, two side pairs flanking a large central sclerite, this with two large, lateral posterior projections, and two smaller median posterior projections (Fig. 4); phallosome (Fig. 5) Y-shaped anteriorly, external parameres stout, distally rounded, bearing pores; anterior pair of endophallic sclerites stout, bow-shaped, wide anteriorly, pointed posteriorly, with an acuminate projection on outer edge; posterior pair of endophallic sclerites connected anteriorly by a curved bridge, each sclerite long, slender, wide proximally, hooked distally.
Color
(in 80% ethyl alcohol). Body dark brown, with some creamy areas as indicated below. Head with a dark brown oblique band from each compound eye to epistomal sulcus, enclosing the antennal fossae (Fig. 2). Compound eyes black, ocelli hyaline, with ochre centripetal crescents, forming a triangular ocellar group. Vertex creamy white, with a brown spot on each side of the epicranial suture and irregular spots next to each compound eye. Postclypeus with diagonal brown striae. Anteclypeus and labrum brown. Genae creamy white. Antennae: scape brown, pedicel and flagellum pale brown. Mx 1–2 creamy white, Mx 3 brown and Mx 4 brown, with apical third dark brown. Tergal lobes of meso- and metathorax dark brown, thoracic pleura brown, except the metapleura, creamy white. Legs: coxa and trochanter of fore- and mid legs brown; coxa and trochanter of hind leg creamy white, femur of fore- and mid legs with proximal halves brown, distally creamy white; femur of hind leg creamy white, with a subapical brown band; tibiae of all legs brown, distally darker; tarsomere 1 brown, tarsomeres 2–3 dark brown (all legs). Forewings (Fig. 1) hyaline, veins brown, a brown marginal band from R4+5 to distal half of 1A, a brown spot distally on R 2+3, pterostigma dark brown. Hindwings with brown spots distally on the veins (Fig. 1). Abdomen creamy white, with irregular brown spots. Hypandrium yellowish, with sides dark brown; anterior side sclerites dark brown, posterior side sclerites pale brown. Paraprocts and epiproct creamy, with brown spots.
Morphology
As in diagnosis, plus the following: outer cusp of lacinial tip broad, with eight denticles. Forewing pterostigma elongate, widest in the middle; vein M with seven branches; areola postica tall, apically rounded (Fig. 1). Hindwing with M five branched. Paraprocts elongate, setose, each with a macroseta apically dilated, on inner edge, near the apex (Fig. 3); sensory fields with 30 trichobothria on basal rosettes (Fig. 3). Epiproct broadly triangular, wide based, anteriorly convex, posteriorly rounded, with setae as illustrated (Fig. 3).
