Horne & Whittaker, 1985
Carapace medium, around 0.7 mm long, elongate subrhomboidal with bluntly pointed or narrowly rounded extremities, compressed. Weak caudal process well above mid-height position. Female slightly higher and larger than male. Fused zone moderately broad, especially posteriorly.
Mandible coxa long. Second leg with a short, slender knee seta. Fourth podomere of third leg with a strongly spinose anterior margin. Male copulatory appendage with three distal processes: the anterior one short, bicuspate; the central one relatively large, banana-shaped and the posterior one widening distally: basal capsule with an evenly convex anterior margin (P. angliorum 5 ). Living specimens white or pale brown.
P. angliorum has a broader fused zone than P. ensiforme Brady, which it otherwise closely resembles (see also Remarks on P. ensiforme).
So far known only from East Anglia and the Thames Estuary, but may be more widespread as it has previously been confused with P. ensiforme.
