Philyra malefactrix (Kemp, 1915) of the family Leucosidae was recorded from the Kali estuary along with berried specimens. Berried female crab from the muddy, slushy substratum was collected and reared in the laboratory. The larvae were reared in 24 ppt saline water and the rearing water temperature ranged between 24 to 26 oC during the development period. The larvae passed through three zoeal and one megalopa stage. The larvae were compared with the other Philyra larvae reared in the laboratory.
