Aellopos tantalus
Smaller than Aellopos fadus or Aellopos titan titan. Abdomen with sharply marked broad white belt dorsally on segment 4. Forebasitarsus as long as or slightly shorter than tarsomeres 2 to 5 combined; inner surface of tarsomeres 3 to 5 beige. Tarsomeres 3 to 5 not compressed and enlarged. Forewing upperside with medial band vestigial, without distinct white spots, or with only minute spot between M3 and CuA1; postmedial band consisting of three spots between M1 and M2, M2 and M3, and M3 and CuA1, the first of these the largest and often divided. Forewing underside with white lunules posterior to the discal cell highly reduced or absent, and without a medial spot, or with only a minute spot between CuA1 and CuA2. Hindwing upperside with indistinct pale yellow medial band on the upper half of wing; no white patch at tornus.
Male genitalia: Uncus narrower apically than in Aellopos fadus and Aellopos titan titan. Ventral part of gnathos very much anterad, at which point there is a heavily sclerotized band. Subscaphium absent. Phallus with the subapical patch of spines consisting of two or three rows of spines that are shorter than the diameter of the phallus proximal of the patch, patch much longer than in Aellopos tantalus zonata and Aellopos clavipes clavipes ; whip about twice as long as width of phallus with two apical setae.
Female genitalia: Sterigma similar to other species of Aellopos, ostium bursae free.
Aellopos tantalus tantalus and Aellopos clavipes clavipes are essentially allopatric, with Aellopos tantalus tantalus restricted to southern/eastern South America with occasional records from Amazonian Brazil. Records from northern Chile and northern Argentina may be misidentifications of Aellopos clavipes clavipes, the former presumed to be strays. The record from Ontario is certainly a stray and is presumed to be Aellopos tantalus zonata.
