Camiarodes nunni sp. nov.

Length 2.9–3.1 mm (n=2). Pronotal width 0.9–1.1 mm; elytral length 2.0– 2.2 mm, elytral width 1.5–1.7 mm at broadest point, 1.2–1.4 mm at elytral bases. Head width at eyes approximately. 50 mm. Color dark to light tan or brown, uniform or head and venter may be darker or hypomeron lighter; punctures more or less weakly impressed dorsally, though stronger on the epistoma and also larger and more strongly impressed on the elytral striae; vestiture present throughout apart from hypomeron, erect to suberect and decumbent and longer on the pronotum and elytra. Dorsum of head with surface irregular. Antennomeres 1–7 elongate, A8–A11 shorter with A10 slightly longer than wide; A1 and A2 subequal in length, slightly wider than segments A3–A6 which are extremely slender, elongate (> 4x as long as wide); A7 wider than preceding four, subequal to A6; A8 cylindrical, narrower than segments A7 and A9; A9–11 subequal, wider than other segments; A11 subconical, slightly longer than A10. Clypeus broad, transverse but slightly narrowed anteriorly; labrum transverse and subquadrate, ~2.5x as long as clypeus, weakly emarginated anteriorly, without trumpet-shaped sensillae. Mandibles somewhat triangulate tapering in apical 1/5; mandibular apex acute and not bifid; prostheca setose; mola ~0.30 as long as total length of mandible (measured along inner face), transversely ridged. Maxilla with lacinia and galea subequal, largely membranous and each with combs of 6 and 7 rows of blunt short spines, respectively; spines (uncus) and sensillae absent. Galea more slender, lacking minute sclerite at base. Maxillary palpi four-segmented; basalmost palpomere short and curved; palpomere 2 elongate and curved and not distally expanded, about 5x the length of segment 1; apical palpomere weakly expanded (~1.2x as wide as penultimate palpomere), membranous digitiform sensilla at apex not present (though smaller sensillae present apically). Labial palpi 3-segmented, terminal palpomere slender (approximately 0.4x width of palpomere 2) and slightly elongate (1.3x as long as palpomere 2) and not membranous; interior faces of basal labial palpomeres setose. Mentum transverse, trapezoidal, apex approximately 0.6x as wide as base. Submentum transverse and lacking groove.

Pronotum with two sublateral impressions in anterior half, a median longitidunal groove that is obliterated at the middle of disc, two lateral grooves at basal 1/3 along lateral carinae, and 4 deep, broad submarginal punctures at the base.

Male pro- and mesotarsi with tenent setae on tarsomeres 1–3, and tarsomere 4 of all tarsi lobed below.

Male terminalia. Male sternum 8 broad, transverse and deeply incised. Genital ring with tergite X more or less narrow with a posterior strut, laterotergites (tergites IX) apically setose and somewhat notched laterally, sternite IX broad. Aedeagus ( Figs. 11 a–b) with penis (median lobe) having sides more or less subparallel in dorsal view, ventrally compressed and sinuate in apical 1/3 and curved ventrally at apex. Parameres slender and about 2/3 the length of penis, apices rounded and setose, inner margins with setose; phallobase membranous about 1/2 length of penis, connecting dorsally by a membrane to form a ring. Endophallus spinose, with 2 elongate sclerites apically.

Etymology. The genus name Camiarodes alludes to the morphological resemblance of this species to the genus Camiarus ; it was originally coined as a manuscript name by Dr. Willy Kuschel (NZAC), who first recognized it as new. The specific epithet nunni honors John Nunn, through whose efforts the majority of these specimens were collected.
