Abstract
Two new species of pygmygobies
of Trimma with barred color patterns are described
from French Polynesia. Trimma erwani, n. sp.,
is described based on two specimens collected at Fatu
Hiva, Marquesas Islands. It is distinguished by its
unique color pattern within the genus consisting of
diagonally slanting grey-and-yellow bars on the body,
5 or 6 predorsal scales, and 16-17 unbranched
pectoral-fin rays. Trimma lutea, n. sp., is
described based on specimens collected from the Austral
Islands in French Polynesia, as well as from Rarotonga,
Cook Islands. It is distinguished by its color pattern
consisting of alternating grey-and-yellow to reddish-yellow
vertical bars on the head and body and scale margins
outlined with melanophores, 4-7 predorsal scales,
and 17-18 unbranched pectoral-fin rays. A mtDNA
COI analysis, including all available sequences on
the mtDNA-barcode project BOLD, shows a well-supported
genetic divergence between each of the new species
and among previously described congeners with sequences
available.
