Definition. Evans (1955) misidentified Pamphila derisor Mabille, 1891 (type locality Venezuela), as detailed above. Hence the taxon Evans identified as Decinea decinea derisor is left without a name. Evans (1955) provided its description in a form of identification key, which is adopted here: this new species keys to L.11.2.(a) in Evans (1955). Differs from its relatives by the lack of side process on aedeagus, two separate pale spots in forewing cell, in males, lower spot smaller and typically opaque, usually an opaque small spot in dorsal forewing cell CuA 2 -1A+2A, and ventrally ferruginous background with some ochreous overscaling, but not as extensive as in Decinea huasteca (H. Freeman, 1969) (type locality Mexico: San Luis Potosi), and less prominent dorsal ochreous overscaling than in the latter species. The holotype, male is from Colombia: Bogota, illustrated in Fig. 12a,b and deposited in the Natural History Museum, London, UK (BMNH), its genitalia are prepared on a mini-slide 936 pinned under the specimen. In addition to this genitalia slide, the holotype bears the following three rectangular printed labels: || Bogota, | Colombia. | Druce Coll. || Druce Coll. | ex | Kaden Coll. || Godman-Salvin | Coll. 1913.—2. ||. Scales are removed from the left forewing of the holotype. Other specimens from the “derisor” series in BNMH curated by Evans may include additional species to be studied and no paratypes are chosen. The holotype identification label will be mailed to curators of the collection to be placed on the holotype.

Etymology. Currently, there are no valid Hesperiinae taxa named for the country of Colombia, which is one of the centers of Hesperiidae diversity. This omission is corrected here. The name is a feminine adjective.
