Table A2.2:	Inclusion of sequences/species in the outgroup analysis (OG), preliminary molecular analysis (Prelim), final molecular analyses (Molecular), morphological analysis (Morphology) and combined analyses (Combined). When several sequences of the same species were available the name is appended with the accession number, strain number or laboratory origin according to Table A2.1. Species names in parenthesis in morphological data are specific species used to gather morphological characters. (Morphological characters were collected for Strongyloides stercoralis and Pelodera punctata respectively before an alternative DNA sequence was chosen. Therefore, in the combined analysis the data for two species are combined.)
