Elytral pubescence is distributed in six ways. Setae on the edges and undersides of the elytra are excluded.
-
Absent or inconspicuous. If present, the setae are short, thin and sparsely scattered on the elytral disc (Fig. 2A)
-
Dense tuft of setae present near the apex of each elytron. (Fig. 2B).
-
Two dense strips of conspicuously pale setae present on the lateral margin of each elytron, often also a thin strip isolated in the middle of the elytral disc. The two lateral strips coalesce anteriorly. (Fig. 2C).
-
Four dense strips of conspicuously pale setae on each elytron. These strips are almost as long as the elytra (Fig. 2D).
-
Uniform covering of distinct erect hair-like setae. These may be the same colour as the elytral surface (Fig. 2E).
-
With scattered short and thick scale-like setae (Fig. 2F).
