Annotation:

The morphology of the larval stages of Arrenurus bicuspidator, A. tricuspidator, and A. tetracyphus is described, with particular attention to diagnostic characters: the shape of the dorsal plate, the proportions between the lengths of the median margins of coxal plates II and III, distances between seta C1 and the median margin of CpI and between seta C4 and the median margin of CpIII, the shape of the extrectory pore plates, and the leg setation.
