Tribe Exaeretini

REDIAGNOSIS: Claws usually elongate with pulvilli ranging from small to absent; endosoma usually relatively short, stout, twisted, S-shaped, composed of two straps united by a membrane often with serrations, castellations, or spicules and with distinct large, twisted secondary gonopore; sometimes posterior lobe of left paramere elevated; labium relatively long extending past hind coxae; most members with dark or sericeous setae on hemelytron; female gentialia variable, posterior wall usually sclerotized and anterior surface microspiculate, without large anterior projections into genital chamber.

DISCUSSION: We place the following genera in the Exaeretini because the parempodia show inflation to the same degree as observed in the genus Moissonia Reuter, 1894 (see also discussion below under Melaleucaphylus ); the endosoma is short, stout, and shows ornamentation on the apical portion of the ventral strap in a comparable position to that seen in Moissonia ; and the pulvilli are small and in some taxa the claws are elongate.

Placement of the new genera Eucalyptophylus and Melaleucaphylus in the Exeraetini provides another biogeographical connection for the Australian Phylinae to other continental areas. We call attention in particular to the potential relationship between Australia and tropical Southeast Asia and the Malay Archipelago, which have an extensive Moissonia fauna, as documented by Schuh (1984 [under the generic names Ellenia Reuter and Ragmus Distant ]), Yasunaga (2010), and Yasunaga and Duwal (2015).
