Camiarodes gen. nov.

( Figs. 8–11 )

Type species: Camiarodes nunni sp. nov.

Diagnosis. Body shape ( Fig. 8 ) long-legged, biconvex, similar to that of the New Zealand camiarine genera Camiarus and Camiarites ; dorsum clothed mainly with long recumbent setae. Head without ocelli; epistomal suture present (stem visible in cleared or weakly pigmented specimens). Antennae elongate, with slender and weak five-segmented club with nearly enclosed periarticular gutters on segments 7, 9 and 10. Labial palp with palpomere 4 weakly expanded. Pronotum with dorsal surface irregular with weak depressions and grooves, anterior angles subangulate, sides sinuately narrowed toward hind margin; hind angles rounded. Scutellary shield visible, triangulate, and firmly attached to elytral bases. Elytra without transverse strigae, with deep striae marked by moderate punctures; epipleura without foveae. Abdominal ventrites 1–5 of equal lengths; abdominal process of ventrite 1 bifurcate. Legs elongate and robust; tarsi 5-5- 5 in both sexes.

Description. Head. Head broad and constricted behind eyes; eyes round and protuberant, coarsely facetted, 11 facets across at greatest length. Head without conspicuous microsculpture but shallowly punctured. Epistomal suture present, with median stem visible in cleared or weakly pigmented specimens. Antennae ( Fig. 8 ) elongate and slender; antennomeres not weakly expanded, antennomere 8 cylindrical, scarcely reduced, ~0.8x as long as preceeding segment. Antennal insertions immediately posterior to epistomal suture, not concealed in dorsal view. Gular sutures present, narrowly separated. Tentorium with well developed anterior and posterior arms and broad tentorial bridge, dorsal arms present, extending approximately halfway to vertex of head and not associated with tentorial pits.

Prothorax. Pronotum transverse in dorsal view, subquadrate, clothed with vestiture of recumbent setae, surfaces irregular with shallow median groove (interrupted at middle), weak sublateral impressions, and lateral groove along posterior margin above carina; bounded on all sides by a bead which exposes the anterior part of hypomeron to dorsal view. Pronotum weakly explanate, widest at middle with anterior angles subangulate and posterior angles weak and subrounded. Hind margin of pronotum with four large, conspicuous, complete punctures. Pronotum with lateral carinae complete, exposing anterior part of hypomeron to dorsal view, without loose fringe of minute setae dorsally and ventrally. Hypomeron glabrous. Notosternal sutures distinct, connecting ventrolateral edge of broad cervical opening with lateral articulations of trochantins. Prosternum short, broad, without transverse carina delimiting procoxal cavities anteriorly and with prosternal process produced posteriorly and expanded to form part of procoxal closure. Coxal cavities completely closed externally by the meeting of the prosternal process and postcoxal projections. Procoxae projecting, coxal cavities weakly transverse; trochantins exposed.

Mesothorax. Scutellary shield triangular, attached firmly to elytral bases; tergites of pterothorax reduced and transverse. Mesocoxae globular, narrowly separated by processes of meso- and metaventrites; mesocoxal cavities open, bounded laterally by mesanepisternal bases, delimited posteriorly by prominent subcoxal bead of the metaventrite that extends to about 2/3 the length of the coxa. Mesoventrite subquadrate, transverse, laterally fused to mesanepisterna marked internally by a ridge. Mesepimera complete, elongate, extending posteriorly to mesocoxal cavity and anteriorly to form lateral regions of prepectus. Mesotrochantins more or less triangulate, not concealed.

Metathorax. Metaventrite transverse, not carinate, discrimen absent. Metacoxae more or less globular, subconical, extending to lateral margins of metaventrite. Metacoxal cavities shallow, narrowly separated by a bifurcate abdominal process of the abdominal ventrite 1. Metepisternal-elytral clamp (metepisternal process) present as an elongate groove.

Elytra. Elytra firmly attached, convex and tapering posteriorly; each elytron with 10 punctate striae (obliterated at humeral angles) of which about five reach the abdominal apex; epipleura not reaching elytral apex, weakly convex and delimited by a bead, with only a few scattered large punctures, visible in lateral view. Hind wings completely absent.

Legs. Legs long, slender, similar to those of other Camiarini. Tibiae clothed with long, erect setae and armed apically with short, blunt spines. Claws simple, lightly curved, each with low basal tooth. Empodium bisetose. Tarsi 5-5- 5 in both sexes.
