Lipogramma klayiis a beautiful and delicate looking species of Caribbean basslet which is no stranger to the pages of Reef Builders. We’ve written about this species at length over the years and now it seems like it may one day have a sister species, or at least an easily identifiable morph.
The Curasub has been making research dives far away from its normal home in Curacao for the last couple of months. It seems that they’ve been finding some really cool new fish at great depths in Dominica because the same Chapman Expedition that brought us apotentially newDecodonspecies of hogfish may have also discovered a newLipogrammaspecies.
The unique pink and yellow basslet has a very similar resemblance to theLipogramma klayifairy basslet but with some notable differences. It’s hard to tell if it is a photographic artifact but theLipogramma sp.‘Dominica’ appears to have a more rosey pink head color compared to the lilac purple ‘true’ Klayi basslet.
然而differenc最明显和重要e between the classicL. klayiand the one from Dominica is the much more pointed anal and dorsal fins. The tail fin is also different with two nearly filamentous extensions which almost give theLipogramma sp.‘Dominica’ a lyretail appearance compared to the smoother outline of a typicalL. klayi.
高级鱼类学researcher of the Chapman Expedition Dr. Carol Baldwin is quick to point out that “Discovering new species is rarely a “eureka” experience — it takes time and effort. Describing something new takes even more work” and that this is merely a it’s aputativenew species based on differences in fin shape and color.
We won’t know for sure whetherLipogramma sp. ‘Dominica’ is indeed a new species until a thorough analysis of morphology and genetics is performed. It’s exciting to see even potential new species of beautiful little reef fish being discovered in the Caribbean, even if it is at great depths, and we look forward to hearing more about the specialLipogrammafrom Dominica.
