Halgerda willeyi from Taiwan

From: Bernard Picton


Bill,

Here are two specimens which I think must be Halgerda willeyi - both from Taiwan (Formosa) in 1983. In view of the recent doubt re. the name formosa ..... I haven't seen the description of H. formosa or the recent paper but I hope Terry & Shireen have it right now! The smaller individual I have seen has far fewer dark makings than the larger one. I could look up my notes to get the sizes if that's important.
Cheers,
Bernard

Dear Bernard,
Yes I think this is H. willeyi which has a wide Indo-West Pacific distribution.
The name 'formosa' doesn't actually refer to the Formosa (Taiwan), it was originally described from Reunion Id in the Indian Ocean. I am pretty sure 'formosa' means sweet or beautiful and I have this vague memory that it was this meaning that some early European explorer applied to Taiwan - because of some sweet smelling spices or perfume.

I have included the original colour figures of Halgerda formosa from Bergh, in my comments on your photo of Halgerda formosa.

Best wishes,
Bill Rudman.
