Abstract
A new species
of dragonet, Callionymus madangensis from Madang,
Papua New Guinea, is described on the basis of a single
male specimen collected with a trawl in about 30–40
m depth near Madang. The new species is characterised
within the subgenus Pseudocalliurichthys by
a small branchial opening; head short (3.7 in SL);
eye large (2.3 in head length); preopercular spine
with a short, straight main tip, six to seven curved
serrae on its dorsal margin and a strong antrorse
spine at its base, ventral margin smooth, slightly
concave; first dorsal fin much higher than second
dorsal fin, with 4 spines, first spine with a long
filament (male); second dorsal-fin distally straight,
with 8 unbranched rays (last divided at base); anal
fin with 7 unbranched rays (last divided at base);
17 pectoral-fin rays; caudal fin elongate, distally
rounded, nearly symmetrical in male (upper rays not
much shorter than lower rays); sides of head, membrane
connecting pelvic fin pectoral fin, and body with
small ocelli; first dorsal fin plain dark grey; second
dorsal fin translucent, rays spotted; anal fin dark
grey; lower margin of caudal fin dark grey, remainder
with vertical rows of brown spots. The new species
is compared with similar species. Revised keys to
callionymid fish species of New Guinea, as well as
of the subgenus Pseudocalliurichthys, are presented.
