Two new millipede genera from northwest Tasmania, Australia (Diplopoda: Polydesmida: Dalodesmidae)

摘要

Setoisenoton pallidus n. gen., n. sp. and Dysmicodesmus jeekeli n. gen., n. sp. occupy small ranges (<5000 km(2)) in the forests of northwest Tasmania. Both have a head+19 rings, metatergites lacking posterior corner extensions, and long, rigid gonopod telopodites reaching at least to legpair 4 when retracted. S. pallidus resembles Notonesiotes aucklandensis Johns, 1970 from the subantarctic Auckland Islands, but differs in gonopod details. D. jeekeli is unusual in the Tasmanian dalodesmid fauna in having basally fused telopodites.
