Abstract
The morphological ontogeny of Punctoribates ghilarovi Shaldybina, 1969 is described and illustrated. This species is most similar to P. mundus Shaldybina, 1973, but is larger than the latter species. The juveniles of P. ghilarovi are light brown, with most prodorsal setae of medium size, except for long seta ro in the larva, and short and smooth seta ex in all instars. The larva has 12 pairs of gastronotal setae, including h3, the nymphs have 15 pairs. Most of them are medium sized and barbed, except for slightly longer dm, dp, lm, lp and h1, and short and smooth h3 in the larva, and short and smooth da and dm, slightly longer dp, and clearly longer h1, h3 and lp in the nymphs. In all juveniles, a humeral organ is present.
