Paraxanthodes cumatodes ( MacGilchrist, 1905)

( Fig. 4H )

Material examined. – 1 male, 5.7 × 4.1 mm ( ZRC 2008.1409 ), Stn. T1 , mud and many sponges, 83–102 m, 9°32.4'N 123°47.3'E, Bolod, Panglao Is., coll. PANGLAO 2004 Marine Biodiversity Project, 30 May 2004 .

Remarks. – This species was first placed in Xanthodes Dana, 1852 , by MacGilchrist (1905), but was later transferred to a new genus, Paraxanthodes , by Guinot (1967b) together with Paraxanthodes obtusidens (Sakai, 1965) . It has been reported from the Red Sea and the Persian Gulf (Guinot, 1976b), and also from New Caledonia in the Pacific ( Davie, 1997). The present specimen agrees with the illustrations provided by MacGilchrist (1905) and Guinot (1967b). This is the first record of this species in the Philippines. Davie (1997) argued that Paraxanthodes is closely allied to the genera Alainodaeus , Medaeus , Medaeops , Paramedaeus and Monodaeus and forms a monophyletic grouping with these based on the condition of the carapace, sternum, male abdomen and the anterior portion of the carapace anterolateral margin. For this reason, he included Paraxanthodes in the Euxanthinae . Ng et al. (2008) also noted that like other euxanthine genera, Paraxanthodes possesses a strongly differentiated basal tooth on the dactylus of the major chela. Consequently, Paraxanthodes is provisionally placed in Euxanthinae .
