Shell morphology and DNA sequences of the ectosymbiotic bivalves Koreamya (Montacutidae) attached to two different species of inarticulate brachiopods Lingula collected from South Korea suggest that K. arcuata lives commensally with at least two species of Lingula and that its shell morphology may vary according to the host species.
Functional morphology and phylogeny of the rock-boring bivalves Leiosolenus and Lithophaga (Bivalvia: Mytilidae): a third functional clade

- Environmental Science
- 1 February 2007
A molecular phylogenetic analyses using 18s rDNA sequence data strongly suggests that Leiosolenus and Lithophaga are monophyletic genera but that the so-called Lithophaginae (or Leiosorenus plus Lithophago) is a paraphyletic group.

Abstract. Patchy organic sheets often exist in the inner shell layers of endolithic mytilids. They are commonly distributed beneath damaged portions of the shell both in mechanical and chemical…
Molecular phylogeny and shell microstructure of Fungiacava eilatensis Goreau et al. 1968, boring into mushroom corals (Scleractinia: Fungiidae), in relation to other mussels (Bivalvia: Mytilidae)
- M. Owada, B. Hoeksema
- Biology
- 2011
The results of the molecular phylogenetic analysis indicate that F. eilatensis has descended from a coral-boring Leiosolenus species and that it would be adequate for Fungiacava to be treated as Leiosorenus.
A new cryptic species distinguished from Ischnochiton comptus (Gould, 1859) (Polyplacophora: Ischnochitonidae) in central Honshu, Japan
- M. Owada

- 7 June 2016
One of theIschnochiton boninensis is described as a new cryptic species distinct from I. comptus, which is further divided into a cryptic pair of species on the basis of morphological and genetic analyses.
Functional phenotypic plasticity of the endolithic mytilid Leiosolenus curtus (Lischke, 1874) (Bivalvia: Mytilidae)

The molecular phylogenetic tree and haplotype network showed that the genetic sequences of the individuals from all investigated localities were very similar, and implied that they belong to the same species.
Phylogenetic Relationships Among Japanese Species of the Genus Ischnochiton (Polyplacophora: Ischnochitonidae), Including a New Species

- 1 June 2018
A molecular phylogenetic tree based on the four gene regions for 18 chiton species indicated that the seven Japanese Ischnochiton species are polyphyletic and originated from two different clades.
