The fauna of the millipede family Odontopygidae in the Eastern Arc Mountains of Tanzania
is reviewed. Species from the North Pare, South Pare, West Usambara, East Usambara, Nguru, Rubeho,
Uluguru and Rungwe Mts are treated. The odontopygids of the Udzungwa Mts have been subject of
a series of previous papers and are only treated marginally. Six new genera and 25 new species are
described: Antipustia gen. nov., Aptyctosmilax gen. nov., Multipronopea gen. nov., Notogallanus
gen. nov., Praludivera gen. nov., Uncodrama gen. nov., Antipustia hoteldolichoiuli gen. et sp. nov.,
Aptyctosmilax helenae gen. et sp. nov., Calyptomastix ingemanni sp. nov., Calyptomastix vuasu
sp. nov., Calyptomastix xystopygoides sp. nov., Calyptomastix zoltani sp. nov., Chaleponcus jolantae
sp. nov., Chaleponcus nesrineae sp. nov., Chaleponcus schioetzae sp. nov., Chaleponcus sergeii
sp. nov., Chaleponcus soerensenae sp. nov., Geotypodon cristinae sp. nov., Lamelloramus frederiksenae
sp. nov., Multipronopea agneteae gen. et sp. nov., Notogallanus mastacembalus gen. et sp. nov.,
Praludivera paralellamella gen. et sp. nov., Raduliverpa donatellae sp. nov., Spinotarsus axeli sp. nov.,
Syndesmogenus estelleae sp. nov., Uncodrama coronata gen. et sp. nov., Xystopyge bentemarieae
sp. nov., Xystopyge doggartae sp. nov., Xystopyge hippocampus sp. nov., Xystopyge minnae sp. nov.,
and Xystopyge voluntariorum sp. nov. The discussion focuses on diversity and distribution patterns, the
justification for monotypic (monospecific) genera, and the following morphological character types:
the ozopore series, the limbus, the number of setae on the anal valves, the first pair of male legs, the
gonopod sternum, and the sternum of the rudimentary 9th leg-pair.
