A distinctive new Species and new Distribution Records of Stilbopteryginae (Insecta: Neuroptera: Myrmeleontidae) C. N. Smithers Smithers, C. N. a distinctive new species and new distribution records of Stilboptery-ginae (Insecta: Neuroptera: Myrmeleontidae). Proc. Linn. Soc. N.S.W. 110 (4), (1988) 1989: 407-410. Stilbopteryx mouldsorum sp. n., a very distinctive species of lacewing, is described from Western Australia. It has a colour pattern not found in any known species of the genus. New distribution records, based on material in the collections of the Australian and Queensland Museums are given for the other species of Stilbopteryginae. C. N. Smithers, Research Associate, Australian Museum, College Street, Sydney, Australia 2000; manuscript received 12 April 1988, acceptedfor publication 20 July 1988. Introduction The genus Stilbopteryx Newman, with six described species, and Aewpteryx Riek, with three species, constitute the subfamily Stilbopteryginae of the Myrmeleontidae. They include some of the largest and most spectacular Australian lacewings. Some species have a wing length of up to 50mm. Very little is known of the biology of this group. Of only one species {S. linearis Navas) is the larva known (McFarland, 1968). Development from egg to adult took six years in culture. Both sexes of the species of Stil-bopteryx are known, except for S. albosetosa Riek of which males have not been found. All three species of Aeropteryx are known from males only. Riek (1968) published a key which included six of the seven species known at the time. Later (Riek, 1976) he described two more species and included them, with all seven previously known, in a revised key. He also listed the synonyms for each and gave information on the distribution of the species. New (1982) discussed the status of the genera, which at that time were usually included in the family Stilbopterygidae. He gave reasons for considering them to constitute a subfamily of the Myrmeleontidae. During study of collections in the Australian and Queensland Museums a female of a very distinctive, undescribed species of Stilbopteryx was found as well as material which increased knowledge of the distribution of the other species. This material forms the basis of this note. For the sake of completeness the previously known distributions of the species are summarized. In the list of material the initials 'M.S.M.' and 'B.J.M.' indicate specimens collected by M. S. and B. J. Moulds respectively and AM' and 'QM' the Australian and Queens-land Museums.
