Abstract
The clingfish
Unguitrema nigrum gen. nov. et sp. nov. is
described on the basis of two specimens from Madang
Lagoon, Papua New Guinea. The species is very small,
apparently not exceeding 12 mm total length. It is
characterized by 9 dorsal-fin rays, 7-8 anal-fin
rays, 22-23 pectoral-fin rays, and 12 principal
caudal-fin rays; plain black colour without white
stripes; a short head with head length 4.7-4.9
in SL; a narrow head with head width 7.5-8.5
in SL; a posteriorly situated anus, with the disc-to-anus
distance 3.2-3.5 in SL; three rows of papillae
distally on disc region B; and two central papillae
clusters on disc region B with only two papillae each.
The new genus is distinctive for unusual central short
claw-like appendages within some papillae.
