basalis (Oplomus) Walker 1867a: 122 . [Fig. 16]

Original data: “ a. Ega. From Mr. Bates’ collection.” [holotype]

HOLOTYPE ♂: red-margined holotype disc; green-margined type disc; “Ega / 58 6”; “19. OPLOMUS BASALIS .”; “NHMUK 010592401”. Right antenna, fourth and fifth left antennomeres, and anterior legs missing (Fig. 16).

Current status: Oplomus festivus Dallas, 1851 (originally synonymised to Oplomus tripustulatus Fabricius by Stål 1870: 28, as Var. b; see Distant 1880: 31; Distant 1900a: 63; Schouteden 1907: 35; probably synonymised to Oplomus marginalis Westwood by Thomas 1992: 60, although there is no mention of a new synonymy; Rider & Rolston 1995: 845–846 replaced preoccupied O. marginalis Westwood by O. festivus Dallas).

Note: Thomas (1992: 60) erroneously reported a label as reading “Equ.” and consequently listed Ecuador in the distribution of the species. The label actually reads “Ega/58 6”; Ega is now known as Tefé and is in Brazil.
