Key to Parilia View in CoL species

1a. Carapace prominently elongated ( Figs. 1C View Fig , 3C View Fig ); cardiac spine very long ( Fig. 3C View Fig ); lateral margin of carapace entire, smooth ( Fig. 3C View Fig ); frontal lobes rounded ( Fig. 3C View Fig ); lateral processes on distal part of G1 very wide, fan-like ( Fig. 8 View Fig J–L) (South China Sea, northern Vietnam and Philippines)................................... ........................................................ Parilia ovata Chen, 1984 View in CoL

1b. Carapace globose to subovate; cardiac spine long or short, never strongly elongated; lateral margin of carapace with 1–4 low tubercles, smooth or with small granules; frontal lobes triangular; lateral processes on distal part of G1 flared but not fan-like.....................................................................................2

2a.
