Review of the encyrtid (Hymenoptera, Chalcidoidea, Encyrtidae) parasitoids of Dryinidae (Hymenoptera, Chrysidoidea, Dryinidae): second contribution and description of a new species of Cheiloneurus Author Guerrieri, Emilio text Journal of Natural History 2006 2006-12-28 40 41 - 43 2395 2401 http://dx.doi.org/10.1080/00222930601088040 journal article 10.1080/00222930601088040 1464-5262 5230689 Cheiloneurus bonariensis De Santis Guerrieri and Viggiani (2005) failed to indicate that Cheiloneurus cristatus (Girault) remains a valid species, while C. bonariensis is a replacement name for C. cristatus De Santis 1957 nec Girault 1915 . In the interest of nomenclatural stability I hereby correct this error. Cheiloneurus quadricolor (Girault) Cheiloneurus brevipennis Fatima and Shafee, 1994 . syn. nov. C. brevipennis Fatima and Shafee (1994) was synonymized with C. yasumatsui Trjapitzin (1971) by Anis and Hayat (2002) . Guerrieri and Viggiani (2005) synonymized C. yasumatsui with C. quadricolor but failed to indicate C. brevipennis as a junior synonym of C. quadricolor . 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 australiae type’’. On the card, two dryinids (presumably Pseudogonatopus , that is indicated as the host of this species), four remnants ( two adults and 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 LECTOTYPE of C. australiae . I have mounted on a slide one fore wing and one antenna of the lectotype and 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. australiae with C. flaccus .
