capitate

Mainly referring to antennae, but occasionally to other anatomical features such as palps: having a clubbed shape with a relatively long, slender stem, but with an abruptly bulkier, thicker, possibly globular distal head, the capitulum. The term capitate is not strictly distinguished from clavate, but where a distinction is desired, it is that the club of a capitate antenna is abruptly distinct from the shaft, and the head tends to be short and more or less globular. The club of a clavate antenna generally is a more or less tapered thickening, sometimes hardly distinct from the shaft.
