Material examined.

Holotype: New Caledonia • ♂; " 21°33'36"S / 165°45'20"E NEW CALEDONIA: Prov Sud. Col d’Amieu, 440m el, 4-16.iii.2007 headlamp search"// “EMEC1139863” GoogleMaps Holotype pinned, with genitalia in a separate microvial. Specimen relatively well-preserved, but with missing palpomeres, left antennomeres 2-11, right tarsomeres 1-5, left and right mesotibiae and mesotarsomeres 1-5, and left and right metatarsomeres 1-5. Source collection EMEC, deposited MNHN. Type locality as given on label.

Diagnosis.

Most similar to C. magnus . However, the latter species has striae 2-5 shallowly impressed from near the elytra base to the apex (vs. 2-4 impressed only in the apical 1/3, and 5 in apical 1/2) and apical lamella of the median lobe more widely rounded at tip (Figs 25 View Figures 22–31 , 26 View Figures 22–31 ). Also resembles C. cyllodinus but in C. amieuensis the eyes are conical, head lacking a notch deep enough to receive the antenna ventral to the eye and the male metafemur does not have a prominent, ventral tooth. The male aedeagus is distinctly different (Fig. 25 View Figures 22–31 ).

Description.

Habitus. Small sized for oodines BL: 7.20 mm, BW: 3.50 mm, with ovate, moderately convex body (Fig. 20 View Figures 18–21 ). Color and luster. Dorsal and ventral surface primarily black, with pronotum sides brownish black, fore part of head and femora dark reddish brown, antennomeres 1-3 and tibiae reddish brown, palpi, antennomeres 4-12 and tarsomeres yellowish brown. Integument moderately glossy, without spectral iridescence. Microsculpture and punctation. Head, pronotum and elytra with isodiametric meshes well impressed, prosternum in front and abdominal ventrites in middle with slightly transverse meshes, prosternal process with isodiametric meshes less impressed than on dorsal surface, rest of ventral surface with scarcely-visible sculpticells or sculpticells not apparent. Micropunctation evident on head, pronotum, prosternum medially (including prosternal process) and medial parts of abdominal ventrites, more or less uniform, lacking on remaining part of ventral surface; abdominal ventrite 1 with some large punctures at sides, ventrites 2-5 at sides moderately rugose. Chaetotaxy. Labrum with six setae distributed more or less evenly across width each in its own socket. Clypeal setae present. Supraorbital setae absent. Elytron without discal setiferous punctures. Abdominal ventrites 1-5 without ambulatory setae. Head. Less than 2 1/2 × as wide as pronotum (Suppl. material 2: Table S1). Eye relatively large, moderately protruded, EyW/HW: 1.47. Labrum anterior margin straight. Frontoclypeal suture present medially, almost obliterated at sides. Antenna moderately long, with last segment not exceeding pronotal base and pubescence starting from segment 4. Mentum tooth with paramedial border distinct. Thorax. Pronotum ~ 1 2/3 wider than long (PW/PL: 1.70); width at apex less than 2 × at widest point (PW/PA: 2.16). Disc with middle line very fine, without apical transverse impression; anterior angles slightly, widely rounded at tips, anterior margin concave, anterior submarginal sulcus present, interrupted in middle. Prosternal process rhomboidal, finely bordered at apex, not bordered between coxae. Mesosternum anteriorly with two prominent, symmetrical tubercles separated by a space smaller or equal to diameter of one of them. Metepisternum wider than long, with lateral margin barely convex, coadunation with epipleuron long, extended along most of length. Elytra. Slightly longer than wide (EL/EW: 1.11). Basal margin forming distinct denticle at shoulder, ended medially just before level of parascutellar puncture. Humeral submarginal carina present. Apical sinuation shallow. Parascutellar striole absent, striae 1-5 present at apex, ended well before basal margin; striae 6 and 7 well impressed throughout, 7 reaching basal margin, 6 ended near but not reaching margin. Elytral intervals 1-6 where evident at apex, convex, interval 7 slightly convex in anterior 1/2, clearly convex in posterior 1/2, interval 8 convex throughout, from 2-3 × narrower than interval 7. Granulation in marginal furrow evident in first 1/5 and last 3/5, lacking in second 1/5. Legs. Male protarsomeres 1-3 asymmetrically expanded, beneath with adhesive setae (tarsomeres 2 and 3 fully covered, tarsomere 1 covered only on apical 1/4), each of them transverse, wider than long. Female genitalia. Female specimens unknown. Male genitalia. Median lobe of aedeagus in lateral view long, curved ventrally, with rather thin apex (Fig. 35 View Figures 32–40 ); lobe in dorsal view, with apical lamella well bent to left, with left side clearly concave and right side slightly sinuate (Fig. 25 View Figures 22–31 ); basal bulb rounded dorsally; sclerotized portion of the endophallus with three sclerites, most clearly visible from ventral side.

Etymology.

The specific epithet Coptocarpus amieuensis is based on the type locality Col d’Amieu and is treated as an adjective.
