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.

Paratypes very similar in shape, sculpture and color to the holotype. Females with shorter antennae. Spermathecal capsule ( Fig. 11E View Fig ) with globose basal part; collum about twice as long as apical part; ductus thin, short, apically inserted.

Distribution

Endemic to Mt Humboldt, Southern Grande Terre ( Fig. 15A View Fig ).
