Centipede Research

Research on the Chilopoda is presently limited to Dr. Shelley’s lab at the North Carolina State Museum of Natural Sciences (NCSM), and involves taxonomic and faunal studies in the order Scolopendromorpha. The focus is on this order for three main reasons: 1) it includes the conspicuous, large-bodied species that are well known to the general public; 2) the larger scolopendromorphs can deliver a painful bite and hence can hurt humans; and 3) the taxonomic problems with this order are less severe than those with the more diverse orders Lithobiomorpha and Geophilomorpha, where the difficulties greatly complicate and hinder their research. The initial objectives were to elucidate the North American fauna, and early publications included faunistic studies on North Carolina & Florida (Shelley 1987, Shelley & Edwards 1987) and treatments of the subfamily Plutoniuminae (Cryptopidae) (Shelley 1990, 1997; Shelley & Backeljau 1995). Basic taxonomic research was necessary to clarify and stabilize names (Hoffman & Shelley 1996, Shelley 2000a), and all this work culminated in a faunistic study of the entire North American fauna (Shelley 2002), which was published by the Virginia Museum of Natural History and can be ordered through their website at http://www.vmnh.net/ . The continental fauna is also summarized, with photos and distribution maps of certain taxa, on the NCSM website at http://www.naturalsciences.org/research/inverts/centipedes/index.html. At the request of colleagues in Hawaii, Dr. Shelley has also authored or co-authored works on the centipede fauna of this state, most of which is introduced (Shelley 1991, 2000b; Zapparoli and Shelley 2000; Bonato et al. 2004).

The scolopendromorph centipede research has recently expanded beyond North America into the Neotropical region, but there has also been one publication on an Australian species (Shelley 2000c, Shelley & Heatwole 1996, Shelley & Kiser 2000). Dr. Shelley is now functioning as a co-advisor to Amazonas Chagas Junior, a centipede graduate student at the Museo Nacional/Universidade Federal do Rio de Janeiro, Brazil, who visited the NCSM from August-November 2003 on a “mini-PEET” grant from the Society for Systematic Biology. The focus of Amazonas’ research is a revision of the subfamily Scolopocryptopinae (Scolopocryptopidae), which occurs in the New World, western Africa, and along the Pacific Rim from Japan to New Guinea, and the first publication is a treatment of the genus Newportia in Mexico and a description of an obligatory cave species (Chagas & Shelley 2003). A number of additional, joint studies on the Neotropical fauna are in progress; ones currently in varying stages of completion are as follows:

1. First authentic record of Scolopendra morsitans from North America and a review of its global occurrences (in preparation).

2. A catalog of New World species of Scolopendra (in preparation).

3. The genus Cormocephalus on Caribbean islands (in preparation).

4. The genus Hemiscolopendra in Mexico (planned).

5. A popularized, illustrated key to scolopendromorph genera in the Western Hemisphere (planned).

6. Review of the genus Rhoda (in preparation).

7. New records, species, and synonymies in the genus Tidops (planned).

Dr. Shelley is also collaborating with J. G. E. Lewis, in the UK, and G. Edgecombe, in Australia, on a work standardizing centipede terminology, which has been submitted to a journal for publication.  He is also collaborating with 8 other specialises on an international project, funded by the Global Biodiversity Information Facility, to develop a web-based taxonomic listing of all currently recognized centipede species in the world; Drs. Shelley and Lewis, and Amazonas Chagas, are preparing the listing for the Scolopendromorpha.

There is ample opportunity for molecular-based studies on scolopendromorphs that would involve Dr. Bond’s lab. Examples of questions regarding the Scolopendromorpha that can only be resolved in this manner include the following:

1. Resolution of the phenotypic similarities between Theatops erythrocephalus, in the Balkan and Iberian peninsulas of Europe, and T. californiensis, in California & Oregon, USA, which are essentially identical externally (see Shelley 1997, 2002).

2. Resolution of the phenotypic similarities between Scolopocryptops rubiginosus, in Japan and northeast Asia, and the form in the midwestern US that currently bears this name. The type locality is in the former region, so the name is properly applied to the Asian form and a new name may be required for the US species if molecular analyses show that the are specifically distinct (see Shelley 2002).
