Definition and diagnosis. Phylogenetic analysis of specimens from Ecuador identified as Oligoria lucifer (Hübner, [1831]) (type locality in Suriname) reveals that they are not monophyletic with it and instead are sister to both Oligoria maculata (W. H. Edwards, 1865) (type locality in USA: Louisiana) and Oligoria percosius (Godman, 1900) (type locality in Mexico, Guatemala, and Panama), being genetically differentiated from them ( Fig. 4): e.g., COI barcodes of Ecuadorian specimens differ from O. maculata and O. percosius by 5.3% (35bp) and 4.6% (30 bp), respectively, and therefore they represent a new species. This new species keys to “ Decinea lucifer ” (L.11.8) in Evans (1955) but differs from its relatives by a small spot and reduced pale overscaling around it in ventral forewing cell CuA 2 -1A+2A. Due to the cryptic nature of this species, most reliable identification is achieved by DNA and a combination of the following base pairs is diagnostic in the nuclear genome: aly3446.8.5:C48T, aly3446.8.5:T87C, aly127.87.2:C51T, aly127.87.2:G75A, aly903.2.14:T860C, and COI barcode: A166G, T277A, T530C, T553A, A628T.

Paratype: 1♂ NVG-18118B07, USNMENT_01531771 Ecuador: Napo, Jatun Sacha Biological Reserve, GPS −1.0667, −77.6000, 30-Sep-1991, D. H. Ahrenholz leg., genitalia H1096 ( Fig. 324–325) [ USNM].

Type locality. Ecuador: Napo Province, km 4 of Tena-Pano Rd., elevation 600 m, GPS −1.033, −77.833.

Etymology. In Latin, obtenebro means darken, make dark, obscure, or conceal. The name is given for the reduced pale scaling near the ventral forewing tornus compared to its congeners and is a noun in apposition.

Distribution. Currently known only from the Napo Province in Ecuador.
