Thanx for the ID. As to accessibility of sampling site, I found this just off the beach on a "featureless" bottom. During six weeks of intensive diving in and around Milne Bay with very experienced muck divers, this was the only encounter. No other divers, including Roger Steene, had ever seen one of these.

I would estimate the size of this little beauty at about 6-7 cm. If anybody is really interested, I took about 10 minutes of digital video from all angles, it being such an interesting creature. Here are all the pertinent details:

Location: Rabaraba, Papua New Guinea
Bottom: Sand and silt
Depth: 70 feet
Time of Day: About 9 PM
Weather: Mostly sunny days, calm at time of photo
Water Temperature: 80 degrees Fahrenheit
Date: 11 April, 2000

Dear Ray,
The lack of published records of this species would suggest it is rare but it may just be that it lives in places that collectors don't often visit. A bit like Euselenops luniceps and Kalinga ornata.

I look forward to receiving your video clip which we will make available on the Forum. I had been planning to add some video clips to the Forum so this will be a good one to start with.

Best wishes,
Bill Rudman.
