Thanks so much for the identification. I submitted a similar specimen for identification last year and that one looks different. You identified it as Bourletiella christianseni. Then, Ken Wolgemuth identified it as Bourletiella rustica. Below are the thumbnails of that specimen. What are your thoughts? Are both specimens B. rustica, with the first missing many scales, or is the first one I submitted B. christianseni, as you thought?



As always, I certainly do appreciate your help.

is the correct name for all these specimens. My initial identifications as B. christianseni are wrong. Ken has transferred all christianseni's to rustica as per my suggestion.
You did record two infraspecific forms of rustica : a pale one previously and a darker one recently.

so much for the explanation. Now, I understand. :)
