Thank you, Roger. After reading the descriptions, it appears that my sdpecimen is a female of Lyssa zampa (the wider white/grey markings lead me to that impression).
PS. I'm slowly getting links to the various volumes, Nos 1,3,5,6,8 & 12 so far!
Part 15 & 16 (a combined volume covering Noctuide: Catocalinae) was published in 2005 but is not yet online, part 17 (Noctuidae, Hypeninae & Herminiinae) is complete and will be published later this year (currently in press) with work well underway on part 13 (the remaining Noctuidae) (possibly due in 2009) and part 2 (Zygaenidae plus a revised checklist of all families covered by the series) in early stages of preparation, probably be published in 2010 or 2011
cheers,
