Macrorrhinia pinta Landry and Neunzig 1998: 499 .

Diagnosis. The forewing length is 4.6–7.0 mm. (The range given in Landry and Neunzig (1997) who listed 82 specimens is 5.0–8.0 mm. No specimen measured more than 7.0 mm among the 69 specimens examined.) The maculation is similar to M. aureofasciella but the transverse bands are more subdued or indistinct and do not reach the costa (not illustrated). The gnathos ( Fig. 36 ) is similar to that of M. endonephele . The phallus ( Fig. 27 ) is laterally curved, whereas it is straight or nearly so in the other species. The corpus bursae ( Fig. 61 ) is barely constricted in the middle as in M. aureofasciella , but the appendicular lobe is larger with the posterior portion broadly dilated and extended to the posterior end of the corpus bursae. The ductus bursae is barely dilated at the level of the corpus bursae and its inception is situated near the base of the appendicular lobe near the juncture of the corpus bursae. There are no signum nor spines except for a small sclerotization at the juncture of the appendicular lobe. The posterior margin of the antrum has a “winged” appearance with a mesial indentation and curved lateral projections wider than the ductus bursae ( Fig. 72 ).

Material examined. Holotype male ( CNC), slide PYR 358; 50 males and females including 18 paratypes: ECUADOR, GALAPAGOS, Pinta, Isabela , Santa Cruz, Espanola, San Cristobal , Seymour Norte , Floreana (1989, 1992), slides PYR 399, PYR 400, PYR 435, PYR 2206, PYR 2207 ( CNC).
