a new species of catshark (Scyliorhinidae: Carcharhiniformes)
Fahmi & William T. White
A new species
of catshark of the genus Atelomycterus is described
from eastern Indonesia based on two type specimens.
Atelomycterus erdmanni is closely related
to A. baliensis and A. marmoratus, being
sympatric with the latter. It differs from these two
species in coloration, external morphology, meristics
and clasper morphology. Atelomycterus erdmanni
differs from A. baliensis in having white spots
present over the body (vs. white spots absent), a
larger first dorsal fin, paired fins closer together,
and pelvic fin farther apart from the ventral caudal-fin
origin. It differs from A. marmoratus in having
far less numerous white spotting, a larger first dorsal
fin, and the clasper glans about half length of clasper
outer margin (vs. less than half length of outer margin).
Its status was also confirmed by genetic analysis
with comparison of the mitochondrial cytochrome c
oxidase subunit 1 (CO1) genetic marker utilised in
DNA barcoding producing a genetic divergence of 4.8%
and 5.3% between the new species and its closest congeners,
A. baliensis and A. marmoratus, respectively.
