description: <i>Paraxanthodes obtusidens</i> (Sakai, 1965) (Figs. 2F, 4E, F) <i>Material examined. –</i> 1 male, 31.5 × 22.2 mm, 1 female, 30.1 × 20.3 mm (NMCR-27357), Balicasag Is., 50–200 m, coll. local fishermen with tangle nets, purch. P. K. L. Ng, 25 Oct.2003; 1 male, 18.6 × 13.0 mm (ZRC 2008.1410), Stn. CP 2747, 118– 124 m, 15°55.53'N 121°42.12'E, off the eastern coast of Luzon, coll. MV DA-BFAR, AURORA 2007 Deep-Sea Cruise, 2 Jun.2007. <i>Remarks. –</i> This species was first assigned to <i>Micropanope</i> by Sakai (1965), but was later transferred to a new genus, <i>Paraxanthodes</i>, by Guinot (1967b), wherein she designated it as the type species. The Philippine material agrees well with the illustrations provided by Sakai (1965a: 103, Figs. 2c, 3e, f) and Guinot (1967b: 723–726, Figs. 51a, b, 59). The live colouration is as follows; the carapace and chelipeds and ambulatory legs are deep reddish-orange, with lighter areas of yellowish-white immediately surrounding the third and fourth anterolateral teeth. There are small patches of white particularly in the cardiac region and in the grooves between the bases of 2M and 3M. The fingers of the chela are dark brown all throughout their length, but not extending to the palm. Other than the type locality (Sagami Bay, Japan), it has also been recorded from Muroto-zaki, Kii Nagashima, Kii Minabe, and Tosa Bay, all in Japan (Yokoya, 1933; Sakai, 1965b, 1976), and also from the South China Sea (Guinot, 1967b). This is the first record of this species in the Philippines.
