Eucrate tripunctata Campbell, 1969 # ( Figs. 8 , 35C–E )

Eucrate tripunctata — present record.

Taxonomy: Campbell (1969), Castro and Ng (2010).

Type: Holotype ò QM W3034 and paratypes in QM.

Type locality: Moreton Bay, Queensland, Australia.

Distribution: Eastern Indian Ocean to West Pacific: from Queensland Australia), Mergui Archipelago, Singapore, Gulf of Thailand ( Castro and Ng 2010) to South China ( Hong Kong).

Habitat: Intertidal to shallow subtidal; substrates of coarse sand and shell and rock fragments.

Remarks: In the recent revision of the family, Castro and Ng (2010) included a live-color photograph under presentation of E. crenata , entirely pale orange in color, from intertidal habitats of Hong Kong (fig. 2B; Pl. 1C). From thousands of trawled specimens our colleagues has sorted, none display such coloration. Based on examined material from local shores, given the markedly broad P5 propodus ( Fig. 8B ), as well as obtuse anterolateral teeth (1 to 3; Fig. 8A ) (cf. Campbell 1969; Castro and Ng 2010), we have identified them as E. tripunctata instead. This species is a new record for the fauna of Hong Kong.
