Clypeolus brookesi (Broun)

( Figures 18–20 )

Acalles brookesi Broun, 1923: 703 . Type locality: Pakarau, North Auckland.

Clypeolus brookesi (Broun) Kuschel, 1990: 79 .

Diagnosis: A small, rotund, highly patterned species. Differs from C. cilicollis by having the elytra more broadly rounded towards the apex; the pale patches on the elytra are very distinct and are triangular in shape, with the posterior margin transverse and acute angles at the suture; the abdominal ventrites are very densely clothed with short, rounded scales that conceal the integument on the lateral parts of the ventrites.

Distribution: North Island: ND, AK, CL (Little Barrier Island), BP.

Remarks: Kuschel (1990) reared a specimen from dead branches of Coprosma macrocarpa . Specimens from the Te Paki (ND) region differ from specimens elsewhere on the Northland Peninsula in a number of ways, including by having the apex of the aedeagus acute, whereas populations elsewhere have the apex of the aedeagus truncate. It is likely that the Te Paki specimens represent a distinct species, but it is outside the scope of this paper to formally describe it here.
