Mexichromis sp. 2 (NSSI 2nd Ed, pg. 162)

The genus Mexichromis is a subgroup of Chromodorididae. It is separated by having a unique radular morphology. Species previously included in Pectinodoris and Durvilledoris are now included in this genus (see NSSI 2nd edition, pages 162 and 163).

Mexichromis sp. 2 has simple dorsal tubercles which are tipped with purple. It has a broad red marginal band. The rhinophores are purple as are the tips of the gill branches.

It has been previously reported only from Vanuatu. Ali's specimen increases the geographic range to Papua New Guinea.

Ali Hermosillo McKowen on location in the Philippines

Ali needs very little in the way of introduction to readers of this site. She has been featured in many of the Branch of the Week (BOW) presentations through the years. Diving with Ali can be infectious assuming you can keep up with her. If you didn't have an appreciation for our friends the sea slugs before diving with her, you will certainly reach quantum levels in that regard as Ali is all consuming in her quest to photograph and document their behavior! In the last few years she even acquired her Doctorate in Opistobrach Studies so her enthusiasm certainly knows no bounds. She has the material for putting together field guides for both the Milne Bay region of PNG and also Anilao in the Batangas area of the Philippines. Let's encourage her when time permits to make that happen!

What more can be said, Ali is the greatest!
