Genus Cocalodes Pocock 

Wanless (1982) reviewed the 12 species known in this genus, which is delimited by the characteristically expanded conductor of the male palp and the elongated and relatively flat body (in comparison with Allococalodes  ). Many males of Cocalodes  have the intercheliceral sclerite ( Maddison 1996) elongated considerably into a horn ( Wanless 1982), a derived trait shared with Allococalodes  that suggests the two form a monophyletic group. Figure 8View FIGURES 2 – 9 shows the horn in a living male C. longicornis Wanless. It  is not easily visible in a living male in normal poses, as it rests between the elongate chelicerae. Some species, such as C. macellus (Thorell)  , lack a projecting horn. Wanless (1982) indicates that even in Cocalodes  males without a horn, the sclerite is unusually large, but it remains to be studied whether it is larger than typical for basal salticids ( Maddison 1996; Maddison & Hedin 2003).

Natural history. In our recent field work three species were found. C. macellus  ( Figs 2–5View FIGURES 2 – 9) was found most commonly at 600 m but as high as 1100 m elevation near Wanakipa, Southern Highlands Province (S 5.3 E 142.5). At 700 m elevation in Varirata  National Park, Central Province (S 9.44 E 147.36) were found C. longicornis  ( Figs 6–9View FIGURES 2 – 9), and C. expers Wanless. All  were found on large-leaved plants at rainforest edge or within the rainforest. C. macellus  was found on Pandanus  , palms and native bamboos; C. expers  on Pandanus  leaves within the forest. Shown in Figure 1View FIGURE 1 are the species of Cocalodes  collected at sites in Papua New Guinea; the Baiteta  forest site was collected by canopy fogging by Olivier Missa in 1995.
