In the interest of nomenclatural stability, I hereby correct this error.    Cheiloneurus flaccus(Walker)     Cheiloneurus australiae  Perkins, 1906: 260. Lectotype ♀, USA(BBMH), here designated, examined. syn. nov. I have examined a card-mounted specimen from BBMH that bears a note handwritten by Perkins on its inferior side with the following indications: ‘‘Budanberg -illegible sign - xi.04’’ and a label handwritten by Perkins with the name: ‘‘ Saronotum australiaetype’’. On the card, two dryinids (presumably  Pseudogonatopus, that is indicated as the host of this species), four remnants ( two adultsand two young instars) of what seems to be a Fulgoroidea and one encyrtid, which is the type species, are mounted. As in the original description, the author did not mention how many specimens of this species he collected; in the interest of nomenclatural stability I here designate this specimen as the LECTOTYPEof  C. australiae. I have mounted on a slide one fore wing and one antenna of the lectotypeand found no reliable differences between this species and  C. flaccus, especially in the distinctive shape of antenna and in the fore wing pattern of hyaline and infuscated areas (see Figures 10–12 in Guerrieri and Viggiani 2005). I, therefore, propose the synonymy of  C. australiaewith  C. flaccus. [390,618,1256,1280] BBMH United States of America USA 5 2398 1 1 lectotype
