( Figures 45–50 )

Acalles lachrymosus Broun, 1881: 729 . Type locality: Whangarei Heads.

Clypeolus lachrymosus (Broun) Kuschel, 1990: 79 .

= Tychanus dux Broun, 1893: 1240 New synonym. Type locality: Clevedon.

Clypeolus dux (Broun) Lyal, 1993: 67 .

Diagnosis: Large; general body shape broadly fusiform. Variable in colouration and development of tubercles and fascia on the elytra. Pronotum with disc evenly convex; clothed with dense scales, often with discrete patches of scales raised so as to form the outline of a vase or a cross. Elytra with pronounced carinae on the humeri; a pronounced carina also present on interstria 8; the lateral pale patches vary in the degree of contrast with the base colour of the elytra, but they are usually more distinct than in C. cineraceus , with oblique anterior margins that often terminate behind the humeri. The elytra are proportionally longer and more narrowly rounded at the apex than C. cineraceus .

Distribution: North Island: ND, AK, CL (including Great Barrier I.), GB, TO.

Remarks: Many specimens have been collected from leaf litter. Specimens have been reared from the dead wood of various tree species, including mānuka ( Leptopermum scoparium ), heketara ( Olearia rani ), karamū ( Coprosma lucida , the association recorded using the synonym Coprosma australis ), and porokaiwhiri ( Hedycarya arborea ) ( May 1987; Lyal 1993). Kuschel (1990) found it in association with Solanum mauritanum .
