John E. Randall, Kwang-Tsao Shao, and Jeng-Ping Chen (2007) Ctenogobiops mitodes
is described as a new species of gobiid fish from 12 specimens from
Pratas Reef in the South China Sea and the Marshall Is., with nontype
specimens from the Solomon Is. and Papua New Guinea, and photographic
records from New Caledonia, Fiji, and Flores, Indonesia. Like others of
the genus, it shares a burrow with alpheid shrimp. It is most similar
to C. pomastictus Lubbock and
Polunin (type locality, Great Barrier Reef), differing in having an
elongate 2nd dorsal spine as an adult, 46-52 scales in longitudinal
series on the body (compared to 55-59 for C. pomastictus), and 1
instead of 2 rows of dark spots on the cheek. Photographic records are
provided for C. pomastictus from New Britain; Redang I., Malaysia; Banda Is., Indonesia; and Phuket, Thailand. Ctenogobius phaeostictus
is described from a single 24.3 mm female specimen collected from the
Madang area of Papua New Guinea at a depth of 10 m. It is distinguished
from the 8 other species of the genus by having 13 instead of 10-12
soft rays in the dorsal and anal fins, an elongate 3rd dorsal spine,
and a unique color pattern of numerous small dark spots, a single
longitudinal row of 5 large black spots, and the apparent absence of a
white spot on the pectoral fins.
Key words: Fish taxonomy, Indo-Pacific, Gobiidae, Ctenogobiops, New species.
