Definition and diagnosis. Phylogenetic trees reveal that a number of specimens identified as Tromba xanthura (Godman, 1901) (type locality in Panama) show prominent genetic differentiation from it ( Fig. 8): e.g., their COI barcodes differ by 3.6% (24 bp), and therefore represent a new species. This new species keys to T. xanthura (K.14.2) in Evans (1955) but differs from it by male genitalia with deeper separation of harpe from ampulla, which is only slightly notched in T. xanthura , but in some specimens of the new species (including the holotype, Fig. 454–455) is separated by a groove, more prominent serrations towards distal end of the dorsal margin of harpe, and less bulky ventral margin on harpe near its fusion with the body of valva. 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: aly 2672.7.10:C117T, aly 1295.7.1:A156T, aly133.6.8:G260A, aly4592.2.4:G73A, aly4592.2.4:A74T, and COI barcode: 49G, 238C, T340C, T367C, T640C.

Etymology. The name is derived from T.xanthura , the southern counterpart of this species. It has been shortened to indicate this is a more northern species. The name is a feminine adjective.

Distribution. From Mexico to Nicaragua.
