Thecacera picta from Philippines
August 11, 2008
From: Marcel Tanke
Hi Bill,
Attached are 2 pictures of a Thecacera picta we saw at Anilao, during a night dive. Please note that the right rhinophoral sheath seems to be in 2 parts. An abnormality?
Locality: Anilao, dive site Twin Rocks, 15 m, Philippines, 12 July 2008, Sandy bottom. Length: 1 cm. Photographer: Marcel Tanke.
Best regards,
Marcel

Yes the papilla on the outer edge of the right rhinophoral sheath is certainly split in two. Looking at other photos of this species and other species of the genus, this does indeed seem to be uncommon.
Best wishes,
Bill Rudman
