Emesis (Mandania) mandarina Zhang & Cong & Shen & Song & Grishin 2025, new species

Emesis (Mandania) mandarina Grishin, new species http://zoobank.org/ 98452F55-3EB2-4B5A-84B1-4D1C8FF074BE (Figs. 2 part, 3) Definition and diagnosis. Genomic analysis reveals that several specimens from Santa Catarina, Brazil, initially identified as Emesis (Mandania) mandana (Cramer, 1780) (type locality in Suriname) are genetically differentiated from it at the species level (Fig. 2); e.g., their COI barcodes differ by 0.9% (6 bp, barcodes do not differ strongly in this species group (Zhang et al. 2024, 2025b)), and, therefore, they represent a new species. This new species is similar to its sister E. mandana in having redder colors of the dorsal side in males, but differs from it by a more uniformly colored orange ventral side of the wings without more prominent redder and broader margins and the lack of a defined ventral hindwing spot at the tornus. Males (Fig. 3a, c) have smaller and more weakly expressed submarginal dark dots, betterseparated dark markings in the postdiscal row on the ventral side, and typically darker (maroon-toned) background color of the dorsal side. Females (Fig. 3b) may have a rounder forewing with a more convex outer margin and a less prominently concave hindwing outer margin at the vein M 2, narrower dashes and crescents in the discal band on the dorsal side with a dash in cell M 2 -M 3 being more strongly offset distad and aligned with the dash in cell M 3 -CuA 1, and paler marginal areas on the ventral side. Due to its cryptic nature and unexplored individual variation, this species is best identified by DNA, with diagnostic base pairs in the nuclear genome: cne4739.1.2:C183T, cne339.14.2:A330T, cne339.14.2:C435T, cne37103.1.5: T462A, cne37103.1.5:T468C; and the COI barcode: T367C, A379C, T578C, T610C.
