Phidiana militaris from Hong Kong

From: Bernard Picton


Hi Bill,
I see that Phidiana indica is being reported by divers quite regularly. I've enclosed some photos to show the differences between this and Phidiana
militaris.

[See head of P. indica in INSET in the photo on the right for comparison. See separate message for photos of whole animals]

Phidiana militaris was quite common in Hong Kong in April 1983 but I only saw one Phidiana indica, perhaps P. indica is tropical whilst P. militaris is more warm temperate in its distribution? Or does P. militaris like more turbid habitats?

PHOTOS:

LOWER: Flat Is., Tolo Channel, Hong Kong - 12 April 1983 - 60mm

Thanks Bernard,
The only thibg I can add is that the only time I have found P. militaris was in the Gulf of Kutch, Gujarat State, NW India. That was certainly a turbid, muddy environment, very tropical environment - but I guess our sample size is rather small. I have added an inset to your upper photo to show the head of Phidiana indica for comparison.
Best wishes,
Bill Rudman.
