The Tree That Needed a Branch

The harder surprise was not how the coral looked, but where it belonged. In a study published in ZooKeys, Odalisca Breedy and colleagues describe Laurinque elenya, a new species and genus that they place in a newly described family, Laurinqueidae. Its anatomy and a broad genetic analysis support a distinct lineage closely related to the family Eunicellidae—not a creature without relatives, but one requiring a different place in the classification.

An October 8 ScienceDaily report, based on material from Pensoft Publishers, brings the finding to fresh attention. The paper itself was published on June 30, 2026. This is renewed coverage of a taxonomic result, not a discovery made this week.

Three markers, several directions

The specimens came from expeditions in 2019 and 2023 using the remotely operated vehicle SuBastian, at collection depths of approximately 360–529 metres. The researchers examined colony form, polyps and the small skeletal structures called sclerites, alongside genetic evidence.

The first genetic results did not give them a tidy address.

Three markers commonly used in octocoral identification produced conflicting evolutionary trees. One mitochondrial marker, mtMutS, placed the coral in Incrustatidae, a family containing encrusting and stolon-forming soft corals without axes. Another mitochondrial marker, COI, pointed toward Eunicellidae. The nuclear marker, 28S rDNA, yielded poorly resolved relationships rather than a clean third answer.

That last distinction matters. This was not three equally convincing witnesses confidently naming three different families. The signals differed in both placement and strength. Even so, the disagreement between the two mitochondrial markers was striking.

A broader analysis compared many regions of the genome, using ultraconserved elements and exons. Two datasets, containing 153 and 1,385 loci respectively, supported the same relationship: Laurinque as the sister group to Eunicellidae. Anatomy supplied the other part of the argument. The colony growth form and sclerites differed from members of that family, supporting the authors’ decision to describe a separate one.

The animal had not broken biology. It had made a familiar shortcut unreliable. The authors specifically caution against using mtMutS alone to infer family-level relationships among octocorals: here, it would have produced an assignment inconsistent with the organism’s diagnostic physical features.

Make room without making things up

The names retain some of the underwater spectacle. Laurinque draws on Tolkien’s Quenya word for “golden tree”; elenya refers to stars, invoking the brittle-star fields around the colonies. The fantasy belongs in the etymology. The family assignment rests on specimens, microscopy and genetic comparisons.

That separation is worth keeping. A beautiful name does not establish a lineage, and an unfamiliar appearance does not automatically warrant a new family. Nor does this case mean genetic markers are generally useless. It shows why the scale of the question matters: a marker useful for relationships within genera need not reliably settle relationships between deeply divergent families.

The coherenceist lesson is concrete: agreement is not something to manufacture by discarding the awkward signal. Here, researchers widened the evidence, compared it with anatomy and revised the classification. A trustworthy scheme needs enough stability to be useful and enough openness to be corrected.

The specimens are deposited at the Universidad de Costa Rica’s zoological museum; the paper also points readers to public sequence and analysis data. That gives the proposed arrangement something better than a confident story: material others can inspect.

Meanwhile, the yellow colonies acquire no new obligations. They were living among stars before anyone found the right branch for them. The paperwork has finally caught up a little.
