The ovigerous female of Alpheus edwarsii (Audouim, 1826) was collected from Buleji, Karachi, Pakistan, and retained in the laboratory. The larvae hatched after 4 days and subsisted within 3 days at room temperature 28oC-30oC in filtered seawater with a salinity of 35-37 parts per thousand and a pH of 7.6-7.8. In order to feed the larvae, Artemia nauplii was used. Two zoeal stages are described, illustrated and compared with those of its congener's larvae known previously.
