GeOchUs sUffUsUs Broun , 1914 ( Fig. 17 )

Geochus suffusus Broun 1914b: 222 . Type locality: Mount Hutt, near Methven.

Type Depository. BMNH : LT, 3 PLT.

Distribution. New Zealand (MC).

Remarks. Broun stated that he had based his description on “about a dozen individuals”, four of which we located in the Broun collection (BMNH). We designate one specimen as the lectotype to stabilize the epithet, with the other three becoming paralectotypes. There were also two variants that we decided were not syntypes.

We place this species into a species group with G. pyriformis .

Type Material Examined. Lectotype, here designated ( BMNH): card-mounted, “3614 [in Broun’s hand]// New Zealand. [red underline] Broun Coll. Brit. Mus. 1922-482.// Mt Hutt 12.4.1912 [in Broun’s hand]// Geochus suffusus [in Broun’s hand]” . Paralectotypes ( BMNH): 3 (1 mounted dorsally), same but 2 lacking the identification labels .
