Author: Trewavas, 1935
Remark: Quote Snoeks and Hanssens (Ref. 55954): "We were unable to examine the holotype of <i>A. macrochir</i> Trewavas, 1935 to investigate the possible synonymy of this species with <i>A. rostratum</i> Trewavas, 1935 as suggested by Eccles and Trewavas (1989) and Konings (1995). Non-type material of <i>A. macrochir</i> in the BMNH, London certainly looks very similar and may be conspecific with <i>A. rostratum</i>."
Comments: Occurs over open sand and feeds on sand-dwelling invertebrates (Ref. 5595).  Solitary specimens usually seen over soft and muddy bottoms.  Feeds on small invertebrates (Ref. 40898).
