JimG 26 Posted December 11, 2012 Taken in Cebu, Philippines. Looks like it should be in the genus Trimma but can't find a match Share this post Link to post Share on other sites
JimG 26 Posted December 29, 2012 Thanks Grivai. I have tried to find info about T.yanoi but am really struggling. Can you point me anywhere please? Trimma sheppardi is another possible but again there is little to go on. Share this post Link to post Share on other sites

JimG 26 Posted December 30, 2012 Thanks Alison. Yes I had read that closely; its about the only thing I could find. I don't think it takes me much further as the colour pattern shown is not quite the same and I know that's never a good guide anyway. The genus seems not to be well described generally and to differntiate between very similar fish seems to depend on lots of detailed measurements, scale counts etc. I guess I will never know conclusively unless I can get in touch with one of the expert mentioned in that paper.

JimG 26 Posted July 10, 2013 Got it at last! For information, it is Trimma haimassum, the Blood-spot Pygmy Goby. Confirmed by Dr. Rick Winterbottom, Ontario Museum who described and named this species two years ago. He also kindly sent me a very detailed paper about this and five other similar species of Trimma he described at the same time. Share this post Link to post Share on other sites
Glasseye Snapper 47 Posted July 11, 2013 Hi Jim, I'm not going to argue with Rick but if he is right than Reef Fishes of the East Indies must be wrong. Their picture is definately much more congruent with T. yanoi, and not really with T. haimassum, which they do include in the book. For T. haimassum they mention "pale yellowish brown to bluish grey with purplish stripe under eye extending onto opercle; lavender stripes across upper edge of orbital rim, and dappled pattern of lavender markings on snout. Caves and ledges on steep outer reef slopes in 15-70m." I would not consider it a good match with your image at all. In contrast, RFEI's T. yanoi resembles your image quite well, just with less constrast in the spots but that is not unusual. The majority of Trimma species are described by Rick so I would stick with his conclusion, just surprised about inconsistency. Bart 1 Share this post Link to post Share on other sites
