HABITAT

The holotype was collected by sifing leaf and log litter in broadleaf and podocarp forests.

ETYMOLOGY

This species is named for a world-renowned beetle specialist and one of the most influential specialists of Pselaphinae during modern time, Donald S. Chandler.

Type species: Nunnea johni sp. nov., here designated DIAGNOSIS

The members of Nunnea may be separated from other faronite genera by the following combination of characters: body length 1.8– 2.5 mm ( Figs. 2 and 3 View Figs ); frontal rostrum prominent and frontal sulcus linear, reaching eyes ( Fig. 5 View Figs ); anterior frontal fovea absent and posterior frontal fovea oval ( Fig. 5 View Figs ); prosternum longer than wide with lateral procoxal foveae ( Fig. 7 View Figs ); mesocoxae divided by distinctively prominent ventral process ( Fig. 9 View Figs : arrow); mesoventrite with promesocoxal foveae and large lateral mesosternal fovea ( Fig. 9 View Figs ); abdominal segment VI at least twice larger than VII ( Fig. 11 View Figs ); abdominal sternites IV–VI with distinctly large basolateral foveae ( Fig. 11 View Figs ); only known from northern South Island ( Fig. 16 View Fig : black triangles and circles).

DISTRIBUTION

New Zealand.

ETYMOLOGY

This genus is named for the collector of the holotype, John T. Nunn, who also provided many valuable specimens for this study.

REMARKS

The members of this genus do not possess distinct external sec- ondary sexual characters. Male abdominal sternite IX is fragile, and partially concealed by sternite VIII, rendering it simple and reduced in appearance. Females possess a more robust, rectangular abdominal sternite IX bearing a pair of long setae that are usually visible in ventral view. Female genitalia, including spermathecae, apparently are mem- branous and were not observable afer clearing specimens using 10% potassium hydroxide.
