Dear Acarology community,

(This is my first if I botch it up...apologies)- I am working on a description of a mite belonging to the genus Schizogynium that I collected recently in Panama. I am trying to verify that this mite is not the mite described in 1893 by Stoll in the Biologi Centrali. Unfortunately, the description and illustration is not detailed enough to be sure. Hence, I would like to see the type specimens. BUT...(my luck) I can't find out where the type specimen is. So, I am sending this message out to see if anyone might have clues to help me find the types (or paratypes).

The mite was named Celaenopsis megisthanoides by Stoll. It was collected by Champion. It is now placed in the genus Schizogynium (Funk, 1965;dissertation). Dr. Funk's dissertation indicates that the location of the type specimen is unknown. Is there a general depository for Stoll material?

If you have any info- you can send it directly to me at : Thanks, Chris J.Marshall

I am in need of information regarding the gut environment (pH, etc.) of mites, specifically mesostigs. has anyone come across any literature on this topic?

Does anyone have an English translation of the two published obituaries of Antonio Berlese? They were published by Del Guercio, in Redia volume 16, v-xix, 1927, and Paoli, Memorie della Societa Entomologica Italiana, volume 6, 55-84, 1928.

If anyone can let me have these translations, I will be happy to refund your costs of copying and postage.

Thank you for your help.

International Symposium on the Relationships of Major Arthropod Groups

Organisers: Richard A. Fortey and Richard H. Thomas (The Natural History Museum, London) Dates: April 17 - 19, 1996. Location: Talks at The Natural History Museum Accommodation at Imperial College, London Estimated costs: Registration will be about 100 Pounds Sterling Accommodation (3 nights) about 75 Pounds Sterling, breakfasts included.

Arthropods are a dominant component of living biodiversity, yet how they relate to one another is still uncertain. These are questions for molecular and evolutionary biologists, palaeontologists and geneticists. The last decade has seen extraordinary developments in these disparate fields: the growth of molecular systematics, the increase in awareness of how genes actually express themselves in design, and, not least, a wealth of new fossils having "exceptional preservation" of soft tissues. But these discoveries have often been made in isolation. The time is ripe for a new synthesis of information from these different fields, and this symposium will bring together the leading researchers in London, to provide a forum to define the problems - we hope solutions, also for the next decade. The meeting will review the problems by inviting leading palaeontologists, zoologists, embryologists and molecular biologists to exchange views. Many of the leading authorities have already agreed to speak. The aim is to illuminate the controls on morphogenesis, and to discover whether new fossils known from the Cambrian are consistent with phylogenetic hypotheses derived from the study of developmental genes, or classical morphology. At the time of the meeting it will have been 17 years since the last book-length review of the evidence on arthropod relationships and much has happened in the intervening years. The format for the meeting will be presentations by each of the 'key' speakers with ample time set aside for discussion by all the participants. Evening discussion sessions will also be held to facilitate the synthesis of results from different fields and to identify areas in particular need of further attention. With additional support from the Systematics Association we will produce a book containing contributions from selected participants with a view to summarising the state of our knowledge about the relationships in this phenomenally diverse and successful group. Invited speakers: Prof LG Abele, Dr M Akam, Dr G Boxshall, Prof DEG Briggs, Dr G Budd, Dr RA Dewel, Dr M Dick, Prof Dr W Dohle, Dr P Selden, Dr GE Edgecombe, Dr DJ Eernisse, Dr G Fryer, Prof Dr O Kraus, Dr NP Kristensen, Dr J Kukalova-Peck, Dr C Nielsen, Prof Dr HF Paulus, Dr L Ramskold, Prof AP Rasnitsyn, Prof FR Schram, Dr WA Shear, Prof JW Valentine, Dr D Walossek, Prof Dr P Weygoldt, Dr PM Whitington, Prof Dr R Willmann, Dr J Zrzavy To place your name on the mailing list for future circulars (next one in October) please contact (preferably by email):

I am currently trying to obtain specimens of either presspecimens of the following Tetranychid species for our reference collection: ,Tetranychus pacificus McGregor, Oligonychus perditus Pritchard & Baker. I would be most grateful for any material received, or for contacts who may be able to help. In return I can offer specimens of a wide selection of Astigmata from our own live collection which currently includes 33 species in 16 genera

I am getting ready to send off an article. Is there more current information on what type of diskettes (DOS/MAC) and software (Word, Wordperfect) the journal will accept? Thanks in advance, DIana Sammataro
