SUMMARYSIBLEY, C.G. and J.E. AHLQUIST. 1981. The relationships of the Australo-Papuan scrub-robinsDrymodesas indicated by DNA-DNA hybridization. Emu 82: 101–105.The taxonomic relationships ofDrymodeswere examined by comparing the single-copy DNA sequences of radio-iodine-labelledD. brunneopygiaDNA with the DNAs of thirty-seven other genera of oscine passerines (Passeres). Of the taxa examined, the scrub-robins were found to be most closely related toEopsaltriaandPoecilodryas, and to be distant from the true thrushes (e.g.Turdus, Erithacus). Drymodesis a member of a varied assemblage of mostly endemic Australasian taxa that includes the Australian robins, flycatchers, monarchs, fantails, whistlers, shrike-thrushes, pitohuis, shrike-tits, the Crested Bellbird, and the quail-thrushes. The wedgebills, woodswallows, and other groups also may be part of this cluster. The honeyeaters, malurine wrens, and Australian magpies, apparently belong to other groups not yet defined in terms of DNA comparisons. The accentors (Prunella), sylviine warblers (Sylvia), white-eyes (Zosterops), muscicapine flycatchers, wagtails (Motacilla), mimic thrushes (Dumetella), starlings, typical wrens (Troglodytes), emberizine sparrows (Zonotrichia) and dippers (Cinclus) are as distant fromDrymodesas are any taxa of oscines the DNAs of which have been compared.
