Definition and diagnosis. Genomic analysis reveals that many specimens formerly identified as Telegonus hopfferi ( Plötz, 1881) (type locality in Mexico, likely south-central or southern, lectotype sequenced as NVG-22068G07) are either Telegonus gilberti (H. Freeman, 1969) (type locality in Mexico, San Luis Potosí, holotype sequenced as NVG-15104B08) or closer related to T. gilberti than to T. hopfferi in the Z chromosome and the mitochondrial genome trees ( Fig. 61b, c). Among them, several specimens from the Amazonian region are not in the same clade as T. gilberti but are sister to the clade consisting of Telegonus bifascia bifascia ( Herrich-Schäffer, 1869) (type locality in tropical America to USA, likely in Brazil, as evidenced by genomic sequencing of the lectotype NVG-15031C04) and Telegonus bifascia siges Mabille, 1903 , comb. nov. (type locality in Brazil) in the nuclear genome ( Fig. 61a, b) being genetically differentiated from them at the species level and not monophyletic with them in the mitochondrial genome tree ( Fig. 61c) with a COI barcode difference of 1.1% (7 bp). Therefore, they represent a new species. Curiously, T. bifascia , the closest relative according to the nuclear genome ( Fig. 61a, b), lacks the white area along the costal margin at the base of the ventral hindwing characteristic of the new species. This species keys to “ Astraptes alector hopfferi ” C.14.26(a) in Evans (1952) and while having greener rather than bluer overscaling at the wing bases and body above, is darker beneath with the white overscaling much restricted or absent along the forewing costal margin, the central white band is more like a tornal spot, typically not entering the discal cell in males (one paratype has a small whitish cell spot near its posterior end), the greenish area extends farther distad in the discal cell and along the inner margin than along the costal margin, while bluish extends the longest along the costal margin in T. panavenus sp. n. (see above) and about the same level as in the discal cell in other close relatives; no traces of subapical forewing pale spots beneath (or above), but some males have a diffuse paler spot in the middle of the dorsal forewing; females are with such a spot, which may be paler and larger, trapezoidal in the cell CuA 1 -CuA 2 with traces of paler areas in the discal cell and the cell CuA 2 -1A+2A, and the forewing beneath is with a white spot in the posterior half of the discal cell. The ampulla is narrower and closer associated with the dorsal process of harpe; this process is more robust ( Fig. 63h ). 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: aly3319.1.3:C45T, aly3762.23.7:G168A, aly3762. 23.7:T150C, aly15386.1.1:C516A, aly15386.1.1:T531A; and COI barcode: T49A, T145C, C349C, T355T, T361T, T424T.
