The entire species exhibits first-order, slightly greyish-white interference colours. The pelaga of Polypodorhabdus escaigii exhibits inclined extinction and length-slow (+) elongation in their natural settling position, in plan view under crossed polars.
Species of Polypodorhabdus are constructed of cretarhabdid shields and a tube cycle surrounding a large central area spanned by an axial cross that supports a distal process. The intercross area is occupied by lateral bars that delimit elongated slits arranged in a single cycle. The number of lateral bars is typically 16-24, a characteristic feature of Polypodorhabdus escaigii.
