Type genus. Meandrusa F. Moore, 1888 View in CoL .

Definition. Meandrusa View in CoL (type species Papilio evan E. Doubleday, 1845 View in CoL currently treated as a subspecies of Papilio payeni Boisduval, 1836 View in CoL ) was placed in the subtribe Teinopalpini Grote, 1899 , but our genomic trees show that it is not monophyletic with Teinopalpus Hope, 1843 View in CoL (type species Teinopalpus imperialis Hope, 1843 View in CoL ) and instead is sister to Papilionini Latreille, [1802] with 100% support ( Fig. 1). Genetic differentiation of Meandrusa View in CoL from Papilionini is approximately the same as of Battus Scopoli, 1777 View in CoL (type species Papilio polydamas Linnaeus, 1758 View in CoL ) from other Troidini Talbot, 1939 (comparable distance from the root, Fig. 1). Therefore, we consider that Meandrusa View in CoL belongs to the tribe Papilionini . However, the tree shows that Meandrusa View in CoL is prominently separated from the rest of Papilionini and, therefore, belongs to a distinct subtribe analogously to Battus View in CoL . This subtribe does not have a name and is proposed as new. As detailed by Miller (1987) for Meandrusa View in CoL , the new subtribe is characterized by bifid tarsal claws and differs from the rest of Papilionini by strongly incurved middle discocellular vein on the forewing, shorter forewing discal cell (less than half of the wing), and scaled tibiae and tarsi, and from Teinopalpini by scaled antennae and prodiscrimen (equivalent to the prosternum of other insects) with a spine. Visually, species in the new subtribe are recognized by the distinct shape of curved forewings (especially in males) with produced and somewhat hooked apex narrowing to a point (less prominently in Meandrusa sciron (Leech, 1890)) View in CoL . A combination of the following nuclear genomic base pairs is diagnostic: pgl 2854.3.1: A400G, pgl827.10.7:G122A, pgl827.10.7:G138A, pgl1898.30.3:G202A, pgl 1397.11.1: G1138A.
