Diagnosis
Arsipoda punctata sp. nov. is an easily distinguishable small, yellow species with a strongly punctate pronotum. Species with similar strong punctuation (A. isola and A. rutai sp. nov.) are very different in color: bronze, metallic in the case of A. isola, and very dark with greenish metallic lustre in A. rutai sp. nov.; moreover, the pronotal punctuation is unevenly sized in A. isola. Genitalia are also clearly different (Figs 9A, F, H, 11I, N).
Etymology
The specific epithet is a Latin adjective referring to the strong pronotal punctuation.
Type material
Holotype
NEW CALEDONIA: ♂, Mueo, [-21.310337 165.020997], 20 May 1928, J.D.A. Cockerell leg. (BMNH).
Paratypes
NEW CALEDONIA: 4 ♂♂, same data as the holotype (BMNH).
Description of the holotype (♂)
Body slightly convex (Fig. 2E); LB = 1.95 mm; maximum pronotal width at base (WP = 0.74 mm); maximum elytral width at basal third (WE = 0.98 mm). Dorsum yellowish, slightly metallic. Frons and vertex strongly punctate, with microreticulate surface; head grooves short, not continued to postantennal region; genae and frontal carina very short; antennae slightly longer than ½ body length (LAN = 1.18 mm; LAN/LB = 0.61), yellow; LA: 100:56:44:56:78:78:78:78:89:78:100. Pronotum slightly trapezoidal, distinctly transverse (LP = 0.45 mm; WP/LP = 1.64), laterally straight (Fig. 5B); anterior angles weakly prominent, obliquely beveled; antebasal transverse sulcus moderately impressed, weakly sinuate; lateral fovea almost indistinguishable; pronotal punctuation large, strongly impressed, dense, evenly distributed on the irregularly microreticulate surface. Elytra moderately elongate (LE = 1.48 mm; WE/LE = 0.66), laterally slightly arcuate; punctuation clearly impressed; interstriae microreticulate and micropunctulate.
Legs yellow; first pro- and mesotarsomeres slightly dilated; adhesive setae present on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter brownish; last abdominal ventrite laterally clearly incised, without special pre-apical impressions. Median lobe of aedeagus (LAED = 0.74 mm; LE/LAED = 2.01) (Fig. 9F) in ventral view thickset, tapered toward base, apically subtruncate, with median rounded small
tooth; ventral surface with complete, shallow ventral sulcus, wider at apical ¾; in lateral view, median lobe slightly curved, gradually thinner toward apex; dorsal ligula elongate, narrow, tapered toward apex.
Biometry
Male (n = 5; mean and standard deviation; range): LE = 1.52 ± 0.10 mm (1.40 Ĺ LE Ĺ 1.66 mm); WE = 0.99 ± 0.06 mm (0.90 Ĺ WE Ĺ 1.08 mm); LP = 0.45 ± 0.03 mm (0.40 Ĺ LP Ĺ 0.48 mm); WP = 0.75 ± 0.05 mm (0.68 Ĺ WP Ĺ 0.82 mm); LAN = 1.22 ± 0.07 mm (1.12 Ĺ LAN Ĺ 1.30 mm); LAED = 0.77 ± 0.02 mm (0.74 Ĺ LAED Ĺ 0.79 mm); LB = 2.05 ± 0.19 mm (1.85 Ĺ LB Ĺ 2.97 mm); LE/LP = 3.58 ± 0.15 (3.38 Ĺ LE/LP Ĺ 3.83); WE/WP = 1.47 ± 0.05 (1.42 Ĺ WE/WP Ĺ 2.35); WP/LP = 1.67 ± 0.03 (1.64 Ĺ WP/LP Ĺ 1.71); WE/LE = 0.65 ± 0.01 (0.64 Ĺ WE/LE Ĺ 0.66); LAN/LB = 0.60 ± 0.03 (0.54 Ĺ LAN/ LB Ĺ 0.64); LE/LAED = 1.99 ± 0.08 (1.88 Ĺ LE/LAED Ĺ 2.09). Paratypes (♂) very similar in shape, sculpture and color to the holotype.
Female unknown.
Distribution
Endemic to Mueo area, Central Grande Terre (Fig. 15B).
