Phylladiorhynchus kermadecensis Schnabel & Ahyong, 2019: 318 , figs. 5, 7.

Diagnosis (modified from Schnabel & Ahyong 2019). Rostrum without subapical spines; lateral margins slightly concave. Carapace with epigastric ridge with 5 spines; anterior branchial margin with 2 spines; anterior protogastric ridge not interrupted medially, without scale behind median epigastric spine; anterior mesogastric ridge not medially interrupted or with small medial gap; anterior metagastric ridge medially interrupted. Thoracic sternite 3 anterior margin sinuous, with shallow median concavity. Antennular article 1 with 5 well-developed spines; distomesial spine small, similar to lower distolateral spine. Antennal article 1 mesial process distally falling well short of second lateral antennular spine; article 2 distomesial spine longer than distolateral; article 3 with [small] to distinct distomesial spine. Flexor margin of Mxp3 merus with 2 prominent spines. P2–4 dactylus flexor margin without upright spines at bases of movable spines.

Distribution. New Zealand, Kermadec Islands, 195– 287 m.

Remarks. As Schnabel &Ahyong (2019) pointed out, the species is characterized by the presence of 5 epigastric spines and 2 spines on the anterior branchial margin. The closest species is P. punctatus , from New Caledonia. Both species can be differentiated by the interrumptions in the gastric ridges (see the differences under the Remarks of this species).
