This species is named for one of the enthusiastic supporters of this study, John Marris. He provided many valuable specimens from South Island.

major
species-group by the following combination of characters: body length
2.2–2.4 mm
; eye one-half length of temple; ventral temple of male head with depressed and weakly projecting temporal lobe and surface bearing small process; pair of thick, dense setae on gular depression; shape of antennomeres and genitalia unique to species; only known from Three Kings Islands.
