in having its metapodal platelet fused to the parapodal plate and free from the peritrematal and hologastric shields. Note, however, that the metapodal platelet is tightly contiguous with the hologastric shield and that in some specimens, at some focal depth, it may even appear narrowly fused with it (Fig. 3A). The metapodal and parapodal plates are fused by a short to elongate connecting

has two inverted-V-shaped ridges on the anterior half of its hologastric shield (see arrows, Fig. 1). The posteriormost ridge, shaped more narrowly, is more conspicuous than the anterior one (which is almost U-shaped). The female paratype photographed shows similar ridges (Fig. 8B). Although at least two undescribed species have similar inverted V or U ridges, the shapes of the ridges in these species are distinct from those of

From this, we could interpret that during a visit of the Berlese Collection in Firenze, Italy, Evans examined types and illustrated them, and later on, lent these illustrations to Ryke. We attempted to retrieve putative illustrations by Evans, or Ryke, but without success. It is possible that a mistake occurred at some point and that
