Arachnida & Myriapoda Collections

The entire scorpion (Scorpiones) collection has been databased as lots, largely through the efforts of Tom Anton and collection manager Dan Summers. As of February 2008, it consists of close to 1000 lots (mostly single-specimen), including 71 type lots, from 53 different countries, with 11 of the 18 scorpion families represented. The Field Museum's types of spiders (Araneae, ca. 140 lots), daddy-long-legs (Opiliones, ca. 100 lots), and pseudoscorpions (Pseudoscorpiones, ca. 80 lots), have all been databased. Relatively little non-type material of those orders has been entered so far. Nearly all the non-type databasing in the spider collection (several hundred records) has been part of the Oonopidae PBI grant project. The holdings visible here are thus a very incomplete record of our roughly 100,000-lot spider collection. The smaller arachnid orders and mites and ticks (Acari) have not yet been databased at all. Catalog numbers (FMNH-INS #### ### ###) have been assigned to all databased arachnid lots, except in Scorpiones, where only recently cataloged type lots have them.
Myriapoda
The collection currently houses over 11,000 lots of millipedes (Diplopoda) identified to at least order (including 15 of the 16 known orders), all of which are included in this database. More are being added on a continuing basis. This total includes over 450 type lots, 376 of which are included in a published type catalog (Zootaxa 1005, 2005). The centipede (Chilopoda) collection contains approximately 4,000 lots, including at least 45 type lots, currently in the early stages of being databased. All databased myriapod lots have been assigned unique catalog numbers (FMNH-INS #### ### ###).

Conversion of the arachnid and myriapod data to KE EMu was funded by the Institute of Museum and Library Services' support for Common Ground, IMLS CM-00-05-0050-05. Data entry of the diplopod lots was supported by NSF PEET grant 97-12438 to Petra Sierwald.

Users should note that in both arachnid and myriapod data, Collection Numbers having the prefix FMHD# represent bulk samples and the number should be cited as part of the specimen data in publications; lots sharing such a number were collected in a single sample. In contrast, the Collection Number prefixes ScrCE and MyrCE are merely internal database numbers with no other significance and need not be cited. Especially in cases where there is limited collecting information associated with a sample, ScrCE and MyrCE numbers do NOT necessarily indicate co-collection of specimens.
Searches are automatically performed as whole-word wildcard searches, i.e., entering Narceus in the Scientific Name field will find all species (and undetermined material) of that genus. The Scientific Name of partly-identified material is the lowest taxon to which it is identified. Entering a subgeneric name alone will find all taxa in that subgenus if the subgeneric name has been entered in our database; if you don't find something that way, try using the appropriate generic name. Searches will take more time with wildcards (*) in conjunction with partial words. Results are sorted by Scientific Name, but if there are more than 5000 records in the result set, they will be unsorted. If you choose to enter more than one term in a field, only records with both terms will be returned. The vast majority of records will not have images.
