Discovery of Cladonema multiramosum sp. nov. (Cnidaria: Hydrozoa: Cladonematidae) using DNA barcoding and life cycle analyses
In contrast to typical planktonic hydromedusae, Cladonema medusae are mostly benthic, with specialised adhesive branches to adhere to the substrate. In this study, a Cladonema species discovered in a laboratory aquarium in Fuzhou, China, was confirmed as a new species, based on morphological and mol...

description | In contrast to typical planktonic hydromedusae,
Cladonema
medusae are mostly benthic, with specialised adhesive branches to adhere to the substrate. In this study, a
Cladonema
species discovered in a laboratory aquarium in Fuzhou, China, was confirmed as a new species, based on morphological and molecular analyses. The species was named
Cladonema multiramosum
sp. nov. Its medusa is distinct from that of congeners possessing substantially more adhesive branches (8–24, rarely 5–7), and tiny branches on the upper radial canals. The validity of
C. multiramosumum
sp. nov. was also supported by molecular phylogenetic analyses based on the mitochondrial 16S rDNA sequence. However,
C. multiramosum
sp. nov. medusa also displayed considerable phenotypic plasticity with respect to its radial canals, tentacles, stinging branches per tentacle, oral tentacles, manubrium, and gonads, hindering species identification based solely on morphology. Although some morphological characteristics of hydroids (filiform tentacles and medusa buds) and nematocysts could also be used as diagnostic characters in the genus
Cladonema
, this information is unavailable for some
Cladonema
species. Thus, the taxonomy within the genus
Cladonema
was re-evaluated based mainly on the morphological characteristics of the medusa. Further revision of the genus
Cladonema
should be made when supplementary information on the life cycle and DNA barcoding are updated. |
