Subclass Chilognatha (Fig. 2, 5)

The geography of Chilognatha ( Fig. 5) is also that of Diplopoda except for north Africa and Western Australia; additionally, this subclass is not known from the Republic of the Marshall Islands. Instead of spreading southward into the Sahara, Chilognatha cuts across Morocco, Algeria, and Tunisia, heads into the Mediterranean, angles into the Benghazi region of coastal Libya, east of the Gulf of Sidra, then back into the Mediterranean again. Consequently, the northern Africa area south of this line in Diplopoda ( Fig. 1) is solely attributable to Penicillata. In Western Australia, the chilognath area in the Kimberley Region is exclusively interior, in contrast to that in Diplopoda as a whole ( Fig. 1).
