Parilia pattersoni Ng, Devi and Kumar, 2018 View in CoL

( Fig. 1E–F View Fig )

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 42, 1 juv. ( CB 5.6 ×CL 6.6 mm including posterior tubercle) , NSMT-Cr 30906.

Remarks. The genus Parilia was extensively revised by Ng et al. (2018) who recognized four species: P. alcocki Wood-Mason , in Wood-Mason and Alcock, 1891, P. major Sakai, 1961 , P. ovata Chen, 1984 , and P. pattersoni Ng, Devi and Kumar, 2018 .

The juvenile male examined is somewhat different from the full-grown specimens described by Ng et al. (2018) in having a narrower, longitudinally ovate carapace similar to P. ovata , but agrees with the photograph and comments on the young male recorded by Mendoza and Nugroho (2021). In P. ovata , the chelipeds and ambulatory legs are nearly smooth, and each carapace lateral margin is armed with only a small tubercle, while in the present species the chelipeds and ambulatory legs are thickly covered with minute granules and tubercles, and each carapace lateral margin is armed with three low, but distinct tubercles that are distinct in the juvenile specimen.

Distribution. Tamil Nadu, southeastern India ( Ng et al., 2018), and off Nias Island in eastern Sumatra ( Doflein, 1904, as P. alcocki ) and Pelabuhanratu Bay in southwestern Java, 183– 255 m depth ( Mendoza and Nugroho (2021). As Ng et al. (2018) mentioned, the record of P. major from the Gulf of Manaar, southeast India, by Vidhya et al. (2017) may be referred to that of P pattersoni .
