Pauropoda (Gr. pauros
, small, + pous,
, foot) are a group of minute
(2 mm or less), soft-bodied myriapods,
numbering almost 500 species. They
have a small head with branched
antennae and no eyes, but they have a
pair of sense organs that resemble eyes
(Figure 20-3A). Their 12 trunk segments
usually bear nine pairs of legs
(none on the first or the last two segments).
They have only one tergal
plate covering each two segments.
Tracheae, spiracles, and circulatory
system are lacking. Pauropods are
probably most closely related to
Although widely distributed, pauropods
are the least well known myriapods.
They live in moist soil, leaf litter,
or decaying vegetation and under
bark and debris. Representative genera
