Allocephalus gamolepis is newly described here for the tribe Vernonieae (Compositae). The new genus, placed in subtribe Dypterocypselinae, is clearly distinct from other genera of subtribe by its capitula in axillary glomerules or spikelets, involucres with fused phyllaries and a biseriate pappus with an outer series of short setae and an inner series of longer flattened bristles. A key for the genera of Dypterocypselineae is provided.
