Camponotus laminatus is a conspicuous member of the arboreal ant community in Fiji, and is frequently encountered foraging on vegetation and occasionally on the ground. The species is most often recognized by its relatively large size and bicolored black and red appearance (except on the island of Vanua Levu where it takes on a more uniform dark coloration). Camponotus laminatus is a close relative of C. levuanus, but can be distinguished from the latter by the presence of erect hair on the pronotum, the dense light-colored pilosity of the gaster in combination with the petiolar node shape. Whereas the petiolar node ofC. levuanus is broadly concave, that of C. laminatus is more often flat to convex, occasionally coming to a point at the apex. However, the petiolar nodes of some C. laminatus are very narrowly concave apically. These can be separated from C. levuanus by the abundant, light-colored pilosity.


There considerable variation in C. laminatus among the different islands of the archipelago is mostly evident in the shape of the petiole, density and length of the gastral pilosity, and color. The petiolar nodes of specimens collected from Ovalau, where the type series was collected, are evenly convex at the apex, and the gasters are covered in a dense pelt of light pilosity. On Viti Levu, there appears to be a split between populations from the southeastern Suva region and populations from the central and western forests. The gasters of those specimens from the Suva area are covered in hairs that are generally denser and longer than their more western counterparts. The difference in pilosity between the two regions is not extreme compared to the difference of gastral pilosity of C. levuanus, but it is stark enough to suggest a geographical restriction to gene flow.
Specimens from Kadavu, Koro, Beqa and Moala are all similar to those of Viti Levu, with gastral pilosity tending towards the denser spectrum and petiolar nodes ranging from convex to very narrowly concave at the apex.
On Vanua Levu, C. laminatus strongly trends towards a darker pigmentation, and the mesosoma is often as dark as the head and gaster. In general, the antennal scapes and hind tibia of the Vanua Levu specimens maintain the lighter, reddish appearance of those from other islands, and in contrast to the dark antennal scapes and hind tibia of C. levuanus. The petiole nodes of these specimens attain a pointed peak at the apex. This distinct shape is shared by one of two specimens collected from Taveuni. The gastral pilosity of some specimens is also dark.
Several series of specimens are uniformly darker than even those previously discussed from Vanua Levu, but are in most ways similar to typical C. laminatus with respect to pilosity, propodeum shape, and size of majors. These include a large series from Nadarivatu (Viti Levu), a few minors from Nosoqo (Viti Levu), and a few minors and majors from Labasa (Vanua Levu). These specimens do not key out easily, but are treated here with reservation as C. laminatus.

Ein Arbeiter im Mus. Godeffroy von Ovalau (Viti-Insel).

Diese Art steht der vorigen sehr nahe und unterscheidet sich ausser der hinten zahnartig verlaengerten Thoraxplatte, welche Bildung moeglicherweise nicht charakteristisch sein koennte, besonders durch die anders gebildete Schuppe und durch den Mangel der anliegenden Pubescenz am Hinterleibe. Die Fuehler fehlen dem mir vorliegenden Exemplare, so dass deren Farbe nicht angegeben werden kann.
