Definition and diagnosis. Phylogenetic trees reveal that a specimen from Suriname identified as Pseudodrephalys hypargus (Mabille, 1891) (type locality in Brazil: Amazonas) is genetically differentiated from a series of P. hypargus that included a syntype ( Fig. 2), e.g., their COI barcodes differ by 2.1% (14 bp), and therefore represents a new species. This new species keys to “ Drephalys hypargus ” (B.6.13) in Evans (1952) and differs from it by being generally paler, has a paler streak along dorsal hindwing vein 1A+2A, ventral dark hindwing border is rounder and without a tooth-like contour in 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: aly4105.1.1:T783C, aly54.9.3:C21A, aly 2178.10.1:A52G, aly345.5.4:G72C, aly2284.13.13:G63C, aly423.15.5:A24A (not T), aly499.4.2:C81C (not T), aly15220.6.2:C129C (not A), aly151.8.3:A126A (not G), aly925.30.8:C24C (not T), and COI barcode: T97C, T220T, T277A, 322G, G622A.

Type material. Holotype: ♀ deposited in the Museum für Naturkunde, Berlin, Germany ( MFNB), illustrated in Fig. 53–54, bears the following five rectangular labels, four white: [Bersaba | Surinam | 1898—9 Michls.], [Coll. | Staudinger], [] (empty label), [DNA sample ID: | NVG-21116E12 | c/o Nick V. Grishin], and one red [HOLOTYPE ♀ | Pseudodrephalys | argus Grishin ].

Type locality. Suriname: Para District, Bersaba.

Etymology. The name is formed by removing hyp from hypargus . In Greek, the prefix hyp [o] means low, under, beneath, down, or less than normal. We removed the prefix, making this species higher. In Greek, argos means bright or white. The holotype is indeed brighter and whiter than hypargus . However, it is not clear whether this trait is general for the species or an individual variation. The name is a noun in apposition.

Distribution. Currently known only from the holotype collected in Suriname.
