Distribution. Indonesia.
Hosts. Unknown.
Etymology. The name is derived from the Latin words “ pallidus ” (pale) and “ clava ” (club), and refers to the pale colour of clava, in contrast with the funicular segments.
Comments. Apsilocera palliclava belongs to the group of species without ornamentation on the vertex. It differs from all the other species in this group mainly in having the hind coxa mostly dark, yellowish clava (Fig. 11), gena hollowed at mouth corner, and clypeus emarginate, with one conspicuous projection on each side (Fig. 29).
