From: Segmentation of the millipede trunk as suggested by a homeotic mutant with six extra pairs of gonopods

Figure 16

Segmental composition of the anterior trunk in polydesmidan millipedes. Segmental composition of the anterior part of the body in the homeotic specimen of Nannaria conservata described in [35], compared to a normal male, as suggested by the multiplicative segmentation model [1517]. As in julidans (Figure 15), the first trunk rings are the legless collum and 3 rings with one leg pair each, followed by typical diplosegments. The number of secondary segments deriving from each primary segment is assumed to be lower (four rather than 16) in respect to the julidans, in agreement with the smaller total number of body rings in adult polydesmidans, compared to adult julidans.
