Abstract

The preparation of the trombiculid section of the checklist of ectoparasites of vertebrates of Africa south of the Sahara (Zumpt, 1959) has made it necessary to clarify the relationships of certain genera, two of which have become very heterogeneous because of uncertainty about the true relationships of the type species: these two genera are Trombicula Berlese and Euschongastia Ewing. The object of the present note is to clarify the present position regarding Trombicula and the many species and various subgenera which have been placed in it. This clarification, necessary in the interests of the checklist, is however only a temporary expedient, because a good deal of work still remains to be done in sorting out a number of species and in seeing what guidance can be given from studies of postlarval stages. One of us (P. H. V.-G.) is engaged on a detailed survey of the larvae which however will not be completed before the checklist must go to press. Meanwhile, some further preliminary sorting out is being published: in a sister paper to the present one (Audy and Vercammen-Grandjean, 1959) on Eutrombicula; another by Audy (1959) on Leptotrombidium Nagayo et al.; and by Audy and Domrow (1957, 1959) on Euschongastia in the Oriental and Australasian regions. The various revisions now in progress take into account the larval characters noted by Vercammen-Grandjean (1956b, c), and Vercammen-Grandjean and Audy (1956), and also studies of postlarval stages by Crossley (1958), Domrow, Manabu Sasa, and ourselves.
