Charakteristisch ist die schwach abgesetzte 3gliedrige Fühlerkeule, die parallele Gestalt, die ferne Punktierung des Kopfes und Halsschildes sowie die grobe und dichte Punktierung der Flügeldecken. Die Unterschiede gegenüber den anderen Arten der Gattung aus Neukaledonien gibt die Bestimmungstabelle wieder. 26.2.

X.1978, "Under bark of dead standing Araucaria", leg. J.C. WATT (1 o, DSER). Verbreitung. Neukaledonien (Grande Terre, Zentralmassiv), Norfolk-Is. Für die Fauna von Neukaledonien ist sie neu erwiesen. Originalbeschreibung. "cf. Black, shining; palpi, legs, and parts of antennae castaneous." "Head evenly convex between eyes, with dense and small but sharply defined punctures; an oblique impression from each side of the clypeal suture to behind the eye. Antennae extending to base of prothorax, first joint moderately large, second somewhat shorter than third, and slightly longer than fourth, ninth and tenth transverse, eleventh slightly wider and longer than tenth. Prothorax about twice as wide as long, sides almost parallel but gently rounded in front, front angles slightly produced to clasp the head, margins rather narrow in front, but dilated to base; punctures much as on head. Elytra with outlines almost continuous with those of prothorax; punctures dense, sharply defined, and distinctly larger than on prothorax, but becoming quite as small posteriorly. Front tibiae moderately wide and parallel-sided, but near base suddenly narrowed and curved; hind tibiae longer than the others (about as long as the third abdominal segment is wide), conspicuously bisinuate and somewhat thickened at apex. Length, 4-0-4-5 mm." "o. Differs in having somewhat thinner antennae, front tibiae decidedly thinner and not suddenly narrowed near base, and the hind ones much shorter and almost straight." "Norfolk Island (A.M. Lea). Type, I. 6622." "The basal joint of the antennae is black and shining, the following joints are either entirely castaneous, or change from infuscate to castaneous, but the infuscation seldom extends beyond the fourth joint. There is some extremely fine pubescence on the elytra and under surface, but it is invisible from most directions. Several specimens are more of a piceous-brown than black, but probably from immaturity." Berne rkungen . Diese Art ist durch den verhältnismässig grossen Körper, schwarze Färbung, nackte Oberseite und vor allem die langen, beim c? am Ende stark gekrümmten Hinterschienen gekennzeichnet. Original wurde sie von der Norfolkinsel beschrieben. Das Vorkommen der Art in Neukaledonien ist in zoogeographischer Hinsicht sehr bemerkenswert (Tafel III, Abb. 10). 26.3. Iscanus apterus sp.n.
