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 3040 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.
