Platynychus : subgenus Displatynychus Ohira , 1987: 92. Type species: Cardiophorus adjutor Candeze , 1875: 17. Diagnosis. Head. Area between antennal fossa and compound eye with carina connecting fossa and eye, or with 2 pits with non-depressed area between them. Prothorax. Pronotum with lateral carina not reaching anterior edge, hidden in dorsal view by overhanging edge of dorsal part of pronotum (= submarginal line); procoxal cavities closed. Pterothorax. Anterior edge of scutellum emarginate. Legs. Tarsomere 4 without ventral lobe or pad extending beyond base of tarsomere 5; tarsal claws with two apices per side. Also. Legs. Tarsal claws with ventral surface convex mesad of basal apex. Bursa Copulatrix. Proximal (largest) sclerites ovoid; paired distal sclerites absent (i.e. a second pair, farther from vagina, at base of spermathecal gland duct); base of spermathecal gland duct with tube-like sclerotisation (Fig. 111), without paired plate-like appendages. Known from PR China, Japan, and South Korea, 2 spp.
