“…Millipedes are a group of arthropods richly endowed with defensive chemicals (Eisner et al 1978;Attygalle et al 1993;Deml & Huth 2000). When disturbed, millipedes eject these allomones as an ooze that spreads up on their bodies, or as a spray sometimes to a distance of about 50 cm (Jolivet 1970).…”

The presence of considerable quantities of hydroquinones including hydroquinone, 2-methylhydroquinone, 2,3-dimethoxyhydroquinone, 2-methoxy-3-methylhydroquinone, and 2,3-dimethoxy-5-methylhydroquinone renders the defensive secretion of Acladocricus setigerus (Silvestri, 1897) significantly different from that of other quinone-producing millipedes. In addition, two hitherto undescribed compounds, namely, 2,3-dimethoxy-5-methylhydroquinone and 2-methyl-3,4-methylenedioxyphenol, were characterized from the defensive secretion. However, it is uncertain if the latter compound is formed after the release of the secretion. The two major compounds, 2-methyl-1,4-benzoquinone and 2-methoxy-3-methyl-1,4-benzoquinone, constitute about 75% of the defensive fluid. Furthermore, hydrocarbons, which are typically present in the secretions of most other arthropods that use benzoquinones as repellents, are notably absent in the secretion of A. setigerus.

“…Millipedes secrete a variety of defensive compounds (Eisner et al 1978, Attygalle et al 1993, Dernl and Huth 2000, Huth 2000. Acladocricus setigerus secretes quinones, as is typical of species in the orders Spirobolida, Spirostreptida, and Julida, and it can spray them at least 38 cm (Potts 1949).…”

The spirobolidan millipede Acladocrieus setigerus (Silvestri, 1897) grows to at least 155 mm long and is so far known only from Chuuk Islands, Micronesia. It occurs mainly in well-shaded habitats, usually on the forest floor and on tree trunks. It sprays defensive secretions from paired, lateral ozopores on trunk segments; the major compounds, identified here for the first time, are benzoquinones. The secretion stains human skin a reddish brown and causes a slight burning sensation, occasionally followed by slight blistering and exfoliation.AMONG THE MORE than 600 islands composing the Federated States of Micronesia (FSM), only six of the larger islands of Chuuk (formerly Truk) Lagoon are known to harbor a millipede exceeding 100 mm in length. Taxonomic and phylogenetic relationships of this and other millipedes in the Pacific are incompletely studied and we follow Jeekel (2001) in treating the giant millipede on Chuuk as Acladocrieus setigerus (Silvestri, 1897) pending a systematic review of the genus. Although A. setigerus was described over 100 yr ago, almost nothing is known of its biology. The scanty and widely scattered literature consists largely of morphological descriptions and briefly if at all annotated listings in faunal survey reports. This study provides new information on the distribution and habitat preferences of A. setigerus together with the first report on the composition of its defensive compounds and the clinical manifes-
