THE RAFFLES BULLETIN OF ZOOLOGY 2009 57(2): i Date of Publication: 31 Aug.2009 © National University of Singapore EDITORIAL The Raffl es Bulletin of Zoology had an productive year for 2009—18 papers in 57(1) and 23 papers in this issue, 57(2). This is a total of 41 papers published in the two regular issues of the Bulletin and an additional 15 in the second crustacean supplement, which was published on 31 July 2009. We are also expecting to publish perhaps three more supplements this year, including a checklist of world decapod genera. Our Associate Editor for Crustacea, Dr. Tohru Naruse, has left the National University of Singapore (NUS) for a faculty position at the University of Ryukyus. Although he is now no longer in Sinagpore, he has kindly agreed to continue serving as an Associate Editor for crustacean manuscripts. We also take this opportunity to welcome a new Associate Board member, Dr. Tran Anh Duc, from the Hanoi University of Science, Hanoi, Vietnam. Dr. Tran is a recent graduate of NUS and specialises in aquatic Heteroptera taxonomy (for example, see Polhemus et al., 2009, and Zettel & Tran, 2009). Research into the history of the Bulletin has revealed that several volumes had publication dates inconsistent with the publisher’s dates as printed on the wrapper(s) of the Bulletin. This has pushed back the dates of publications of several volumes (by a year) and brought forward by a year the date of publication of one volume. The volumes relevant to brachyuran taxonomy have been dealt with in a paper in the second crustacean supplement (Low et al., 2009a). A more detailed and complete review of this issue will be published in an upcoming supplement of the Bulletin (Low et al., 2009b). Low et al. (2009a) also surveyed all brachyuran papers published by the Bulletin and found the RBZ has been publishing an average of 3.5 new species of crabs over a period of eight decades, since the Bulletin’s inception in 1928. This is no mean feat and is an indication of the hard work and effort by authors, the Editorial Board and staff. These same qualities and quantities of hard work have seen the RBZ’s impact factor rise to 0.800 in 2008, up from 0.648 in 2007. We to authors and the Editorial Board their effort and look forward to even greater things in 2010! Tan Swee Hee Managing Editor Raffl es Bulletin of Zoology LITERATURE CITED Low, M. E. Y., S. H.

Diagnostic characters at the subfamily level as well as specifi c distinguishing characters of the pachygastrine larvae are summarized and a list of the described larvae for the world is given. An original identifi cation key to the Oriental and East Palaearctic larvae (14 spp.) is proposed. Basic diagnostic characters of the described larva and puparium are illustrated and documented by SEM images. KEY WORDS. – Stratiomyidae, Pegadomyia, larva, puparium, saproxylic, Malaysia, Thailand. INTRODUCTION 1991). They are often gregarious, with several to many occurring together at the same site. Essentially, they are Woodley (2001) recorded 561 species of world micropantophagous scavengers and they may even shown Pachygastrinae and 19 species and 1 subspecies were certain sapronecrophagous tendencies feeding upon dead subsequently described by Krivosheina (2002: one species; saproxylic insects and their larvae (cf. Mamaev et al., 2004: three species, one subspecies), Krivosheina & 1977). Larvae of Holarctic Pachygastrinae apparently Freidberg (2004: two species), Rozkošný & Kozánek (2007: feed on fermenting sap, fungus spores or decay-producing 7 spp.), Rozkošný & Kovac (2007: one species; 2008: four microorgasnisms (Teskey, 1976). In the gut contents of species) and Woodley (2008: one species). However, larvae a larva of Camptopteromyia fractipennis sporangia with are described for only 48 species (see Table 1), i.e. for 8.3 spores of fungi, bacteria and unidentifi ed organic debris % of the world fauna of this subfamily. were found (Rozkošný & Kovac, 1991). Larvae of Pachygastrinae are generally found under the Keys to the known larvae of Nearctic genera of this bark of dead or decaying trees, rarely also in soil, at roots subfamily were published by Kraft & Cook (1961), of plants, in decaying remains of vegetation or under McFadden (1967) and James (1981), and keys to the known specialised conditions; e.g. larvae of Eupachygaster larvae at the species level are to be found in the fi rst two alexanderi (Bréthes, 1922) were reared from rotting Opuntia papers; the known Nearctic Zabrachia larvae were keyed sulphurea in Argentina (cf. Blanchard, 1923; James, 1967), by James (1965). Larvae of Palaearctic genera may be Zabrachia stoichodes James, 1965, and Cactobia opuntiae distinguished according to Krivosheina (1977), Mamaev James, 1966, from cacti in the southwestern United States et al. (1977) and Rozkošný (1997). A key to Palaearctic and Mexico, larvae of Zabrachia yuccae James, 1965, Neopachygaster larvae is given by Krivosheina (1976) and from yucca in Arizona and those of Camptopteromyia those to Zabrachia by Krivosheina & Rozkošný (1990).
