Fig. 2 in A mountain of millipedes IV: Species of Prionopetalum Attems, 1909, from the Udzungwa Mountains, Tanzania. With notes on "P." fasciatum (Attems, 1896) and a revised species key (Diplopoda, Spirostreptida, Odontopygidae)

Fig. 2. Body size (body diameter / number of podous rings) of ♂♂ of Prionopetalum spp. Based on original measurements and data from the literature (see Table 1). For "other spp." the entries are median values of the intervals in Table 1.The report of "93 (1) Rumpfringen" (corresponding to 92 podous rings) for P. tanganjikum by Verhoeff (1941) has been omitted, as has Chamberlin's (1927) "nearly fourtythree" segments for P. clarum; both are regarded as quite unlikely and are probably erroneous.
