From: The population genetics of parasitic nematodes of wild animals

Nominal species Host(s) sampled Genetic marker(s) Remarks Reference
Globocephaloides trifidospicularis Macropus rufogriseus; M. giganteus (host numbers not given) 24 isozymes (see Table 1) Two host-specific species, with 4 fixed differences. ITS1 and ITS2 sequencing later failed to detect these species [26] [190]
Hypodontus macropi 3 Macropus agilis; 4 M. dorsalis; 1 M. rufogriseus rufogriseus; 1 M. rufogriseus banksianus; 2 M. robustus robustus; 1 M. robustus erubescens; 2 M. rufus; 3 M. fuliginosus; 2 Wallabia bicolor; 2 Thylogale billardierii 28 isozymes Six species detected, with fixed differences at 20–50% of loci. One in M. r. erubescens, M. r. robustus, M. rufus and M. fuliginosus, one in M. r. banksianus and M. r. rufogriseus, and one in each other host. Species status of nematodes in M. r. robustus, T. billardierii and M. bicolor later supported in [191] [27]
Rugopharynx omega 2 Macropus rufogriseus; 1 Thylogale stigmatica 23 isozymes R. omega from each host species had fixed differences at 10 loci. R. omega from T. stigmatica named Rugopharynx sigma [192]
Paramacropostrongylus typicus 4 Macropus fuliginosus; 2 M. giganteus 37 isozymes P. typicus from each host species had fixed differences at 10 loci. P. typicus from M. giganteus named Paramacropostrongylus iugalis. Hybridisation later detected [193] [194]
Macropostrongylus baylisi 2 Macropus giganteus; 15 M. robustus robustus; 4 M. r. erubescens; 15 M. parryi 27 isozymes M. baylisi from M. giganteus had fixed differences at 9 loci compared with M. baylisi from other hosts examined [195]
Rugopharynx zeta 1 Petrogale assimilis; 2 Macropus dorsalis 21 isozymes R. zeta from P. assimilis had 10 fixed differences when compared with R. zeta from M. dorsalis. M. dorsalis parasite named Rugopharynx mawsonae [196]
Rugopharynx australis 1 Macropus eugenii; 5 M. fuliginosus; 3 M. giganteus; 2 M. robustus, 2 M. rufogriseus, 3 M. rufus; 2 Thylogale billardierii; 1 Wallabia bicolor 17 isozymes Six species found, with fixed differences at up to 50% of loci. One in M. robustus and M. rufus, one in M. giganteus and M. fuliginosus, 2 in M. rufogriseus and one each in the remaining hosts [28]
Labiostrongylus uncinatus 1 Macropus dorsalis; 2 M. parryi 17 isozymes L. uncinatus from each host species had fixed differences at 13 loci. L. uncinatus from M. parryi named Labiostrongylus contiguus [197]
Labiostrongylus bancrofti 1 Macropus dorsalis; 1 M. parryi 18 isozymes L. bancrofti from each host species had fixed differences at 15 loci. L. bancrofti from M. parryi named Labiostrongylus turnbulli [198]
Zoniolaimus mawsonae 9 Macropus rufus ITS2 Two sympatric taxa had fixed differences at 3 out of 230 nucleotides. One named Zoniolaimus latebrosus [199]
Papillostrongylus labiatus 1 Macropus dorsalis; 1 M. rufus ITS2 Two taxa, one in M. dorsalis and one in M. rufus, had fixed differences at 40 out of 240 nucleotides. Taxon in M. rufus named Papillostrongylus barbatus [200]
Cloacina ernabella 1 Petrogale purpureicollus ITS1 and ITS2 Geographically isolated taxa had fixed differences at 13 of 606 nucletides [31]
Cloacina caenis 1 Petrogale assimilis; 1 P. herberti; 1 P. inornata; 1 P. mareeba; 1 P. purpureicollis ITS1 and ITS2 Four taxa identifiable by 1–4 fixed differences. One each from P. purpureicollis, P. herberti and P. mareeba, and one in P. assimilis and P. inornata [31]
Cloacina pearsoni 1 Petrogale assimilis; 1 P. herberti; 1 P. inornata; 1 P. mareeba; 1 P. purpureicollis ITS1 and ITS2 Five taxa, identifiable by 2–9 fixed differences. One taxon in each host species [31]
Cloacina robertsi 1 Petrogale assimilis; 1 P. herberti; 1 P. inornata; 1 P. mareeba; 1 P. purpureicollis; 1 P. persephone ITS1 and ITS2 Two taxa, identifiable by 10 fixed differences. One taxon in P. persephone, the other in all other host species. [31]
Globocephaloides macropodis 4 Macropus dorsalis; 1 M. agilis ITS1 and ITS2 G. macropodis from each host species had fixed differences at 5.2% and 7.1% of nucleotides in ITS1 and ITS2, respectively [26]
