Remarks. Squilla phalangium Fabricius, 1798 , originally described from India but with the original type material lost, was long held as a nomen dubium until stabiliZed by Holthuis (2000) through neotype designation. Holthuis (2000) selected a specimen of Acanthosquilla acanthocarpus (Claus, 1871) from Bombay as the neotype of Squilla phalangium , creating the combination Acanthosquilla phalangium . Ahyong (2001) showed A. phalangium to be referable to Bigelowina Manning, 1995 , and a senior synonym of Acanthosquilla humesi Manning, 1968 (described from Madagascar and subsequently reported from India; Ghosh 1984).

Acanthosquilla dighaensis Ghosh, 1998 , described from off Digha, West Bengal, has unfortunately been oVerlooked in recent literature (e.g., Ahyong, 2001; Ahyong et al. 2008). Ghosh (1998) noted the similarity between A. dighaensis and A. humesi Manning, 1968 , the two nominal species supposedly differing slightly in rostral shape, the number of moVable spines on the outer margin of the uropodal exopod, and arrangement of submedian denticles on the telson. The synonymy of A. humesi with B. phalangium notwithstanding, features characteriZing A. dighaensis outlined by Ghosh (1998), howeVer, do not bear scrutiny; the apparently distinctiVe features of A. dighanesis agree precisely with B. phalangium . The type account and figures of A. dighaensis conform clearly to the neotype and published accounts of B. phalangium (Ahyong 2001; Ahyong et al. 2008). As such, the two species are herein synonymiZed. Bigelowina phalangium is already well known from India, haVing been preViously recorded from Bombay (type locality), Madras, Mandapam, Parangipettai, Sandheads, and Goa (Kemp 1913; Chopra 1934; Ghosh 1984; Shanbogue 1986; Lyla et al. 1997; Holthuis 2000).

Distribution. Indo-West Pacific from east Africa and Madagascar to India, Australia, the South China Sea, Taiwan and Japan; intertidal to less than 10 m (Ahyong 2001).
