In general, cuticular extracts showed a series of straight chain alkanes being arranged in two (or three, respectively) distinctly different patterns: 1) a pattern with a gaussian quantitative distribution ofalkanes from C23 to C36 was noticed in extracts of C. gigantea and H. gibba, with C29 – C32being most abundant. 2) A pattern exhibiting a saw-tooth-like quantitative distribution ofalkanes – with only odd-numberd alkanes being abundant – appeared to be characteristicfor S. carinatus. 3) Extracts of Z. falzonii showed no hydrocarbons. The hydrocarbons are considered to origin in a lipid layer which is covering the cuticle: this layer is regardedto represent the inner – and in some cases the only – layer of the oribatid cerotegument. The differences in cuticular hydrocarbon profiles among oribatid species may representa promising point of attachment for further chemosystematic studies.}, }
