The new species Ecsenius springeri is described
from 6 specimens, 32.742.8 mm SL, collected
at the Kokas area of the Fakfak Peninsula in the Birds
Head Seascape of western New Guinea, West Papua Province,
Indonesia. The new species is a member of the Bicolor
Group of Ecsenius, which also contains E.
bicolor and E. namiyei. The group is distinguished
from congeners in having cirri on both the anterior
and posterior rims of the anterior naris (vs. on the
posterior rim only) and in commonly having multiple
vertical pairs of pores in the lateral line. Ecsenius
springeri is most closely related to E. bicolor
and superficially resembles the striped variety of
that species. However, it consistently differs in
having a narrower black mid-lateral stripe that ends
more anteriorly; a more distinct white stripe along
the mid-side of the body; a more extensive orange
area on the posterior half of the body; and either
lacks a pinkish-to-orange diagonal band behind the
eye or, if present, it is very faint. The two species
diverge by 8.5% in the mtDNA COI barcode marker sequence
