Diagnosis. The male of Opsiphanes fabricii differs from the males of Opsiphanes jacobsorum and Opsiphanes periphetes stat. nov. in the DHW with a defined submarginal band extending to the anal region, usually as wide as the DFW oblique band, between CuA 1 and 2A. The female of Opsiphanes fabricii , on the other hand, differs from the female of Opsiphanes jacobsorum in the yellow DHW submarginal band, and from the female of Opsiphanes periphetes stat. nov. in the continuous DHW submarginal band between the veins, from the costal margin to, usually, M 2; the DHW submarginal band has the same width as the DFW oblique band ( Figs 169a View FIGURE 169 , 171a View FIGURE171 ). Opsiphanes fabricii and Opsiphanes merianae stat. rest. are practically indistinguishable by the external morphology, and are differentiated by means of the genitalia. While the male of Opsiphanes fabricii has the tegumen in dorsal view with an anteriorly projected margin, in the male of Opsiphanes merianae stat. rest. the anterior margin of the tegumen has a slight median concavity. The female of Opsiphanes fabricii has a C-shaped signum while Opsiphanes merianae stat. rest. has two parallel signa. The geographical distribution can also be used to separate the two species; while Opsiphanes fabricii subspecies are trans-Andean, Opsiphanes merianae stat. rest. subspecies are cis-Andean. Opsiphanes fabricii is closely related to Opsiphanes jacobsorum , Opsiphanes merianae stat. rest. and Opsiphanes periphetes stat. nov. (genetic distance 0.9–1.2%, 1.2–1.9% and 1.0–1.7%, respectively).

Male genitalia. Tegumen in dorsal view with anterior margin anteriorly projected, shorter than the uncus; anterior projection of saccus in lateral view twice as long as dorsal arms of saccus ( Fig. 179 View FIGURE 179 ).

Female genitalia. Lamella antevaginalis membranous medially and sclerotized laterally; lamella postvaginalis rounded medially; ostium with weaker sclerotization than lamella ante and postvaginalis; corpus bursae longer than the ductus bursae, with C-shaped signum ( Fig. 180 View FIGURE 180 ).

Variation. Subspecies vary in the following characters: DFW, the width of the band inside the discal cell, and in the recesses of the anterior and posterior margins of this band; the width and length of the oblique band; due to variations in the width of these bands, the bifurcated appearence is not always continuous. DHW, the width of the submarginal band. VHW, the zigzag submarginal line EIII is not always evident ( Figs 169–178 View FIGURE 169 View FIGURE 170 View FIGURE171 View FIGURE 172 View FIGURE 173 View FIGURE 174 View FIGURE 175 View FIGURE 176 View FIGURE 177 View FIGURE 178 ).
