This group contains a single species from the host genus Ducula . It has both sexes with thickened sagittal band posterior to dorsoanterior head plate ( Figures 98, 100 View Figures 95–111 ); marginal head carina rounded, complete; body elongate ( Figure 1 View Figures 1–18 ); and each side of metanotum with two long, two short setae ( Figure 2 View Figures 1–18 ). Male antenna with scape barely enlarged, lacking third segment spur ( Figure 98 View Figures 95–111 ); genitalic mesosome compact, triangular; anterior portion with four pores, each side with reduced lateral sclerites ( Figure 99 View Figures 95–111 ). Female with subgenital plate groove broad, rounded, lacking lateral setae ( Figure 101 View Figures 95–111 ).

Material

4 males, 4 females (including holotype male, allotype female, 1 male, 1 female paratypes of C. becheti ), ex D. goliath , New Caledonia (2).

Remarks

The very large size of this louse, in conjunction with the structure of the genitalia and the male antenna, is distinctive. Despite having only two long metathoracic setae, the existence of small lateral sclerites around the mesosome hints at a distant relationship between this louse and those in the longiceps group.
