Type species.

Feronia impressifrons Chaudoir 1865, by monotypy.

Description.

Head. Clypeo-ocular sulci deeply impressed, divergent; mentum moderately or shallowly emarginate, sides divergent, paramedial pits distinct and deep, or absent; median tooth emarginate or bifid; paraglossae small, without elongate setae at apex; ligular sclerite with two seta on apical margin; maxillary palpifer with one basal seta; antennae filiform, with three basal segments glabrous. Thorax. Pronotum subcordiform, trapezoidal or quadrate, two marginal setae; pro-, meso- and metasterna glabrous; proepisternum smooth; elytra free or fused, bordered at base, nine fully impressed striae, apicolateral plica large and visible, parascutellar stria present, angular base of stria 1 present or absent, parascutellar setigerous punctures present at base of stria 2, three discal punctures confined to third intervals, posterior pair touching or situated near stria 2, intervals flat or convex; hind wing full or reduced (reduced in New Caledonian species); anterior tarsi of male with three basal segments expanded and squamose beneath, all tarsi dorsally glabrous. Abdomen. Ventrites 3-6 transversely sulcate; aedeagus (Figs 11, 13) ostium dorsal, median lobe oriented left side up in repose; parameres conchoid; female reproductive tract (fig. 12) without dorsolateral bursal lobe, bursa gooseneck form, elongate spermatheca broadly attached on posterior face of bursa, spermatheca with appended gland, without duct digital diverticulum, with elongate spermathecal gland duct diverticulum.

Generic distribution.

Caledonia, New Guinea, New Zealand and Tasmania.

Notes.

This is a species-rich genus, with about 25 species described from Australia. However, this is probably less than one third of the true diversity. In all areas where it occurs, but particularly in Australia and New Guinea, this taxon needs revision. The four species described here are based on a modest number of specimens and collecting events; there is certain to be more new species in New Caledonia to be discovered. The two species described by Fauvel in Notonomus , Pseudoceneus irideus (fig. 10B) and Pseudoceneus savesi (fig. 10C), share no generic-level characters with that genus. They have the following features found in Eu chroina and/or Prosopogmus (a combination of plesiomorphic and synapomorphic states), which are not found in Notonomus : Clypeo-ocular sulci deeply impressed; abdominal ventrites 3-6 transversely sulcate; and spermathecal gland with duct diverticulum.
