Philinopsis cyanea from Reunion Island

February 18, 2008
From: Hugues Flodrops

Dear Bill,
On the same night [see message #21233], about three meters away, I found a second Philinopsis which looked like P. cyanea. The classical yellow lines on the head are modified.

Locality: Etang-Salé, 1 metre, Reunion Island, Indian Ocean, 27 November 2007, Night. Length: 60 mm. Photographer: Hugues Flodrops.

I hope that you can explain these variations.
Bests regards.
Hugues

Dear Hugues,

Both this animal and the one in your earlier message are colour forms of the same species. I have included a close-up of the head to show the sensory bristles which are found on pads on each side of the mouth. Although they are usually not as obvious as in some species of Chelidonura, sensory bristles are characteristic of all species of the family Aglajidae

Best wishes,
Bill Rudman
