It somewhat resembles the Silurian Haliestes,[1] which was used to infer various details that are not well-preserved (e.g. cephalon, palps, ovigers, leg annulations, abdomen) on the former's redescription in 2024.

Each leg begins with a possibly annulated coxa and ends with a long, hook-like terminal claw.

Each podomere from the fourth segment is wide and flattened, with most of them bearing tubercles and sparse pairs of long setae along the inner side.

[2] The name Pentapantopus derives from the word "penta" meaning "5” in reference to the belief that it had five pairs of walking legs, alongside "pantopus", a common suffix for sea spiders.

The species name vogteli honours Hans Vogtel, a former slate worker who helped find numerous fossils during the process of roof-slate production.
