[4] Localities include Kakepuku mountain in the Waikato, Wainuiomata in the Wellington Region, Toko near Stratford, Cape Egmont, and Mount Messenger Conservation Area[5] in Taranaki, Bushy Park[6] and Hunterville in the Manawatū-Whanganui Region, Whangarei Heads in Northland, Ohingaiti,[7] the Kaimai Ranges between Waikato and the Bay of Plenty,[8] and the Mount Tongariro/Lake Taupō area.

He described the species based only the shell, which the German geologist Ferdinand von Hochstetter had brought back from New Zealand.

[7] Pfeiffers's original text (the type description) is very short: first is shell characteristics in Latin and then incorrect statement in German that it is the largest Daudebardia.

It reads as follows: T. imperforata, depressissima, ambitu ovalis, solidula, striis incrementi distinctis et lineis impressis radiantibus sculpta, fulva; spira minima, ⅛ longitudinis occupans; anfr.

2½, ultimus latere subcompressus; columella superne crasse callosa; apertura oblonga, intus submargaritacea.

Obwohl über den Bewohner dieser in den Urwäldern der mittleren Waikatogegend gesammelten Gehäuse mir keine Notiz vorliegt, so ist es doch nach dem ganzen Habitus und allen Charakteren nicht zu bezweifeln, dass die Schnecke der Gattung Daudebardia angehört, deren grösste bis jetzt bekannte Art sie ist.The shell is rudimentary, auriform, thin, opaque, oval, increasing irregularly.

Inner lip is thickly callous, terminating below in 1 or several minute tubercles, and spreading broadly above over the parietal wall.

The inside of the aperture is strongly callous in the centre and towards the columella, where there is a well-impressed muscular scar of the columellar muscle.

A pair of grooves running along the median line from the mantle to the muzzle define a row of small tubercles.

The mantle has an even margin, with 2 small lappets on the under-side; the right proceeds forward from a little behind the respiratory pore (pneumostome), extends to almost one-third of the length of the mantle-margin, and forms a narrow fold; the left is minute, simply a rudiment, and in some specimens it is difficult to detect.

The pharynx (the largest part of buccal mass) is so large, occupying almost the whole length of the visceral cavity.

[7] The reproductive system is remarkable for extreme reduction of male organs and the absence of receptaculum seminis (spermatheca).

[7] Schizoglossa novoseelandica usually lives in rainforest under logs, but it can hunt its prey a few metres above the ground in the trees.

[12] Schizoglossa novoseelandica is carnivorous and predatory, preferring snails Otoconcha dimidiata from the subfamily Otoconchinae, family Charopidae and also feeding on earthworms[7] and on its own species (cannibalism).

[13] Eggs are laid in August, and they are found principally under a good thickness of decaying fern-leaves, in little heaps of from 6 to as many as 14.
