Diagnosis
This species is similar in shape, sculpture and often color to A. gomezzuritai sp. nov. and A. rostrata ( Figs 2A, F View Fig , 3C View Fig ). They are distinguishable from other Arsipoda species by the elongate antennae (LAN/ LB: ³ Ż 0.70, ♀ generally Ż 0.60) and the elongate frons with narrow frontal carina. The three species can be reliably distinguished by the shape of genitalia ( Figs 9B, G View Fig , 10D View Fig , 11J, M, S View Fig ).
Etymology
The name is a Latinized word referring to the elongate frons of the species.
Type material
Holotype
NEW CALEDONIA (S): ³, Humboldt (S track), -21.90517 166.35621, 800–950 m, maquis, beating along track to Col de Vulcain, 9 Nov. 2008, M. Wanat leg. ( MNHN). GoogleMaps
Paratype
NEW CALEDONIA: 1 ♀, same data as the holotype ( MNHW).
Description of the holotype (³)
Body moderately elongate and convex ( Fig. 2A View Fig ); LB = 2.72 mm; maximum pronotal width at base (WP = 0.89 mm); maximum elytral width near the middle (WE = 1.30 mm). Dorsum bronze, metallic. Frons and vertex irregularly wrinkled and punctate; vertex concave; head grooves moderately impressed, not continued to postantennal region; genae and frontal carina clearly elongate; antennae clearly longer than ½ body length ( LAN = 1.98 mm; LAN/LB = 0.73), basally light brown, gradually darker toward apex; LA: 100:64:71:86:107:107:118:121:121:111:139. Pronotum slightly trapezoidal, weakly transverse (LP = 0.58 mm; WP/LP = 1.54), laterally weakly concave; anterior angles not prominent; antebasal transverse sulcus clearly impressed, distinctly sinuate; lateral fovea not clearly distinguishable; pronotal punctuation dense, small and shallow; surface microreticulate. Elytra moderately elongate (LE = 1.98 mm; WE/LE = 0.66), laterally clearly arcuate; punctuation clearly larger than pronotal punctures, clearly impressed; interstriae smooth, micropunctuate. Legs yellowish, with darkened femora; first pro- and mesotarsomeres distinctly dilated; adhesive setae present on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter brownish; last abdominal ventrite laterally incised, without special preapical impressions. Median lobe of aedeagus (LAED = 1.14 mm; LE/LAED = 1.73) ( Fig. 9B View Fig ) in ventral view thickened, slightly narrower at apical fourth, and clearly narrower at base; apical part subrounded, with a wide median tooth; ventral surface smooth; in lateral view, median lobe curved at basal fourth, then straight; dorsal ligula short, from apical third to preapical part of median lobe of aedeagus, triangular, with wide base.
Biometry
Male (n = 1): LE = 1.98 mm; WE = 1.30 mm; LP = 0.58 mm; WP = 0.89 mm; LAN = 1.98 mm; LAED = 1.14 mm; LB = 2.72 mm; LE/LP = 3.43; WE/WP = 1.46; WP/LP = 1.54; WE/LE = 0.66; LAN/LB = 0.73; LE/LAED = 1.73. Female (n = 1): LE = 2.13 mm; WE = 1.43 mm; LP = 0.63 mm; WP = 0.93 mm; LAN = 1.90 mm; LSPc = 0.21 mm; LB = 2.91 mm; LE/LP = 3.40; WE/WP = 1.54; WP/LP = 1.48; WE/ LE = 0.67; LAN/LB = 0.65; LE/LSPc = 10.22. Paratype (female) very similar in shape, sculpture and color to the holotype; antennae shorter. Spermatheca ( Fig. 11J View Fig ) with globose-elongate basal part; collum thickset, short, slightly longer than apical part; ductus elongate, apically inserted.
Distribution
Endemic to Mt Humboldt area, Southern Grande Terre ( Fig. 15A View Fig ).
