| Abstract |
A new talitrid genus Solitroides is erected along with a description of a new species, Solitroides motokawai, from the Annamite Range, Vietnam. Solitroides motokawai, new genus & species, possesses the simplidactylate pereopods 3–7: this is the first record of simplidactylate landhoppers from the Northern Hemisphere. The simplidactylate Solitroides motokawai, new genus & species, is diagnosed by the following combination of characters: innermost apical robust seta on outer plate of maxilla 1 leaning inwards; arcuate outer plate of maxilliped; slender maxilliped palp without lobes, its article 4 coalescing with article 3; oblique palmar margin of propodus on gnathopod 1 in female; large and folded coxal gill 6; apically setose oostegite 5; marginally bare peduncles of pleopods 1–2, and shortest pleopod 3 with minute simple setae on its inner and outer margins, each pleopod with developed rami; and rhombic telson with slightly cleft apical part. Additionally, nucleotide sequences of nuclear 28S ribosomal RNA and histone H3 as well as mitochondrial cytochrome c oxidase subunit I and 16S ribosomal RNA from the holotype and paratype were determined. A key to the talitrid species recorded from Vietnam is provided. |
