A new species of goby, Lubricogobius
nanus, is described from near Alotau, Milne Bay
Province, Papua New Guinea on the basis of four adult
specimens, 9.510.9 mm SL. Diagnostic features
include 1011 segmented dorsal-fin rays, 89
segmented anal-fin rays, the presence of both anterior
and posterior nostrils, a low fleshy keel mid-dorsally
and mid-ventrally on the caudal peduncle, a mid-lateral
row of widely-spaced sensory papillae on the side
of the body, approximately 15 scattered sensory papillae
on the middle portion of the caudal fin, body depth
3.23.4 in SL, mainly brown coloration with yellow
fins, and an exceptionally small size (<11 mm SL).
Photographs and comparative morphological data are
presented for the other four members of the genus,
including L. dinah, L. exiguus, L.
ornatus, and L. tre.
