Description Two novel species of Ceratomyxa infecting marine
ornamental fishes from Indian waters are described. Marine
ornamentals, Chaetodon collare and Chaetodon decussatus,
collected from Vizhinjam, along the southwest coast of India
and Acanthurus leucosternon collected from Lakshadweep
islands ofArabian Sea revealed Ceratomyxa infections in their
gall bladders. Mature spores of Ceratomyxa from Chaetodon
collare and Chaetodon decussatus were elongate and slightly
crescentic, with rounded ends, and measured 5.20± 0.32 μm
in length and 16.32 ± 1.29 μm in thickness. Polar capsules
spherical, equal in size and measured 2.23 ± 0.16 μm long
and 2.24± 0.20 μm wide. Posterior angle measured 157.75
± 8.650. Principle Component Analysis and molecular analysis
using partial SSUrDNA sequences showed the isolates
from these two hosts to be identical. Morphological, morphometric
and molecular analysis using partial SSUrDNA sequences
revealed the taxonomic novelty of isolates and are
hence treated as Ceratomyxa collarae n. sp. Mature spores
of Ceratomyxa from Acanthurus leucosternon were elongate,
slightly tapering with rounded ends, and measured 7.34
±0.92 μm in length and 24.37 ± 2.34 μm in thickness. Shell
valves were equal, joined by a narrow suture line. Polar capsules
spherical in shape, equal in size, 2.59±0.32 μm long and
2.46 ± 0.32 μm wide, and polar filament measured 18.68
±2.54 μm. Based on morphological, morphometric and molecular
analyses, the present species of Ceratomyxa is distinct, considered
as a new species and named Ceratomyxa leucosternoni
n. sp. The paper also discusses the prevalence of the recovered
parasites and host specificity of Ceratomyxa collarae n. sp.
