New and little-known thread-legged assassin bugs from Australia and New Guinea (Heteroptera: Reduviidae: Emesinae)

Ploiaria metapterina sp. n. is described from SE Australia. The new species has unique fore leg armature and seems to be related to the Australian P. guttala WYGODZINSKY, 1956 and P. musgravei WYGODZINSKY, 1956. The apterous female of the New Guinean species P. biroi WYGODZINSKY, 1966, previously known only from a macropterous male, is described first. The type depository of P. biroi, erroneously given with the original description of the species, is the Hungarian Natural History Museum, Budapest. Bargylia longispina sp. n. is described from NE Australia. It differs rather sharply from all previously described species and many characters connect it to the African genus Bobba. The relationships between Bargylia and Bobba are discussed.
