Diagnosis

This species is similar in shape, sculpture and often color to A. longifrons sp. nov. and A. rostrata ( Figs 2A, F View Fig , 3C View Fig ). They all are distinguishable from the 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 their genitalia ( Figs 9B, G View Fig , 10D View Fig , 11J, M, S View Fig ).

Etymology

Male patronym. Named after Dr. Jesús Gómez-Zurita (Institut de Biologia Evolutiva, Barcelona, Spain) for his contribution to the knowledge of Arsipoda in New Caledonia.

Description of the holotype (³)

Body moderately elongate and convex; LB = 2.50 mm; maximum pronotal width at base (WP = 0.83 mm); maximum elytral width at basal third (WE = 1.20 mm). Dorsum dark bronze, metallic. Frons and vertex irregularly wrinkled and punctate; head grooves distinctly impressed, not continued to postantennal region; genae and frontal carina elongate; antennae clearly longer than ½ body length ( LAN = 1.98 mm; LAN/LB = 0.79), basally light brown, gradually and slightly darker toward apex; LA: 100:69:61:92:115:115:131:138:131:123:154. Pronotum slightly trapezoidal, moderately transverse (LP = 0.54 mm; WP/LP = 1.53), laterally weakly concave; anterior angles not prominent; antebasal transverse sulcus strongly impressed, weakly sinuate; lateral fovea not clearly distinguishable; pronotal punctuation small and shallow, evenly distributed on the irregularly microreticulate and very sparsely micropunctuate surface. Elytra moderately elongate (LE = 1.88 mm; WE/LE = 0.64), laterally slightly arcuate; punctuation clearly larger than on pronotum, strongly impressed; interstriae smooth, very finely micropunctate. Legs yellow, 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 clearly incised, without special preapical impressions. Median lobe of aedeagus (LAED = 1.17 mm; LE/LAED = 1.61) ( Fig. 10D View Fig ) in ventral view thickset, narrower at base and at apical third, and distally widely lanceolate, with median rounded small tooth; ventral surface with deep ventral sulcus; in lateral view, median lobe straight, with two lateral small humps at apical third, and small sinuate apex dorsally bent; dorsal ligula short, from apical third to apical part of median lobe of aedeagus, narrow, thinner toward apex.

Paratypes generally very similar in shape and sculpture to the holotype; some specimens paler. Females with clearly shorter antennae. Spermathecal capsule ( Fig. 11S View Fig ) thin and curved, with elongate and wrinkled collum; basal part slightly enlarged, not abruptly separated from collum; apical part short; ductus short, apically inserted.
