A previously unknown female and a morphological variability of Colon (Myloechus) koghiense Perreau, 2004, an endemic species of the New Caledonia, is described and figured. Known distribution within the New Caledonia is mapped. Morphology, distribution, Coleoptera, Leiodidae, Coloninae, Colon, New Caledonia, Australian region INTRODUCTION The genus Colon Herbst, 1797 has approximately 150 so far described species worldwide (Peck & Stephan 1996), separated into seven subgenera (Szymczakowski 1963, 1964, 1969, Peck & Stephan 1996). Only eight species (in four subgenera) have been reported from Australasia (Szym- czakowski 1964: 57–58), recently Perreau (2004) described Colon (Myloechus) koghiense from the New Caledonia, based on two males collected by Ivan Löbl. This was the first report of the genus from the Pacific islands, and also first representative of the subgenus Myloechus Latreille, 1807 from Australian region (Perreau 2004). In this paper, a newly collected material of C. (M.) koghiense from the New Caledonia is repor- ted, based on specimens taken mostly by using flight-intercept traps by G. Monteith (Queensland Museum, Brisbane). Altogether, 119 specimens were collected. We describe a previously unknown female of this species and include additional notes on morphological variation of this species, including male sexual characters. Known distribution within the New Caledonia is mapped. MATERIAL AND METHODS Majority of the material is deposited in the Queensland Museum, Brisbane (QMBA); some doublets are also in the private collections of the authors. Material is dry-mounted and glued on points or cards, at least three male specimens from majority of the localities were dissected and the shape of metafemur and aedeagus was examined under magnification up to ×100. Only arbitrarily selected specimens were measured, covering the extremes in size, with precision 0.05 mm. Listed below are corrected coordinates, provided by G. Monteith (in litt.), not those on labels; these coordinates were also used when producing the distribution map. Material is listed in a chronological order, the abbreviation FIT is used for flight-intercept trap. Morphological terminology follows those of Peck & Stephan (1996). RESULTS Colon (Myloechus) koghiense Perreau, 2004 Colon (Myloechus) koghiense Perreau, 2004: 209, figs 20–21; type locality: New Caledonia, Mt. Koghi, 500–600 m.
