This species bears some resemblance to Mexichromis pusilla, but differs in rhinophore, gill, and overall body coloration. About a dozen of these have been found, the first two on the same lagoonside reef at Enewetak Atoll about three weeks apart in March and April of 1982. They measured 12 and 7mm in length and are shown in the top two photos below. The rest were found at Kwajalein.
The third specimen was found at Kwajalein Atoll, crawling on rocks on a lagoon reef at a depth of 5m on 16 November 2008. This specimen measured 10mm and is shown in the four photos below.
The next two shots show the rhinophores and anterior end of the Kwajalein specimen up close.
The specimen in the three photos below was found on a Kwajalein Atoll lagoon reef under a rock at a depth of about 5m on 5 July 2009. It frequently waves its anterior margin up and down as it crawls, showning off its purple oral tentacles.
The photos below show a pair of specimens found on a shallow Kwajalein lagoon reef on 7 May 2012.
The body on a specimen found by Christina Sylvester (below) seemed quite similar to Mexichromis pusilla, but the dark-tipped gills are more like M. sp. e290. Possibly they all should fall under one species.
