Diagnosis
Arsipoda elongata sp. nov. shares the elongate antennae with A. gomezzuritai sp. nov., A. longifrons sp. nov. and A. rostrata (LAN/LB: ³ Ż 0.70, ♀ generally Ż 0.60) ( Figs 1E View Fig , 2A, F View Fig , 3C View Fig ). However, it can easily be distinguished from them by the elongate, laterally parallel elytra, and by the green metallic color.
Etymology
The specific name is a Latinized adjective referring to the elongate elytra of this species.
Type material
Holotype
NEW CALEDONIA (S): ³, Mt Humboldt , -21.8793 166.4232, ca 1400 m, montane maquis, 13 Nov. 2010, R. Ruta & M. Wanat leg. ( MNHN). GoogleMaps
Paratypes
NEW CALEDONIA: 2 ³³, 5 ♀♀, same data as the holotype ( MNHW).
Description of the holotype (³)
Body elongate, rather flat ( Fig. 1E View Fig ); LB = 2.81 mm; maximum pronotal width at base (WP = 0.85 mm); maximum elytral width at basal third (WE = 1.18 mm). Dorsum dark metallic green. Frons and vertex wrinkled and densely punctate; frontal grooves moderately impressed, not continued to postantennal region; genae and frontal carina moderately elongate; antennae clearly longer than ½ body length ( LAN = 2.18 mm; LAN/LB = 0.77), brown; LA: 100:61:69:69:92:100:108:108:108:100:131. Pronotum slightly trapezoidal, moderately transverse (LP = 0.54 mm; WP/LP = 1.58), laterally straight; anterior angles moderately prominent, obliquely beveled; antebasal transverse sulcus clearly impressed, almost straight; lateral fovea clearly distinguishable; pronotal punctuation small, dense, distinctly impressed, evenly distributed on the microreticulate surface. Elytra distinctly elongate (LE = 2.03 mm; WE/LE = 0.58), laterally slightly arcuate; punctuation clearly larger than on pronotum, strongly impressed; interstriae smooth, very finely microreticulate and micropunctuate. Legs light brown, with dark femora; first pro- and mesotarsomeres distinctly dilated; adhesive setae on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter black; last abdominal ventrite laterally clearly incised, without special preapical impressions. Median lobe of aedeagus (LAED = 1.40 mm; LE/LAED = 1.45) ( Fig. 8F View Fig ) slender, in ventral view laterally parallel, slightly narrower in apical part; apex triangular, with a small rounded median tooth; ventral surface with a wide, moderately deep ventral sulcus along central third; in lateral view, median lobe clearly and evenly curved; dorsal ligula as long as half of median lobe, wide but gradually narrower toward apex.
