The first two species of Pseudopolydesmus described, incidentally two of the most widespread and commonly collected ones, were placed in the genus Polydesmus in the early 1800s. Although the authors have occasionally observed specimens with, for example, an ozoporous paranotum that bears only three apparent denticles, or even one that bears five, these are infrequent exceptions to the rule. 201.

In our taxonomic section, we use square brackets to indicate Withrow’s invalid taxonomic assignments. Pseudopolydesmus planicolens – Chamberlin & Hoffman, 1958: 71. In all Pseudopolydesmus species, the blisters are arranged in an identical pattern: three transverse rows of blisters on the metazonite, with a central and lateral blister on each paranotum (Fig. In Pseudopolydesmus, these setae are very small and often difficult to distinguish even under SEM, except in posterior body rings or in small-bodied species, such as Ps. Most commonly collected near the Mississippi River and its tributaries. From the common swallowtail to the iridescent blue morpho, Thomas Marent's stunning photographs provide a close-up view of the remarkable family of insects known as Lepidoptera.

Like other millipedes in Central America, this species sticks to dark, humid nooks within the forest, favoring rotting trees, piles of leaf litter and soil, caves, and other concealed places. Most spiders are harmless to humans and provide a great service to us by eating untold amounts of insects. Process e2 lobe-like, recurved, separate from e3; process e3 very large, subtriangular to spike-shaped; process e4 small and laminate, proximal to terminal tuft of bristles (Figs 18A, 19A, 20A). americanus; Po. minor and Ps.
