Diagnosis
Arsipoda transversa sp. nov. shares a thickset, ovoid body with A. atra sp. nov., A. evax and A. povilaensis sp. nov. ( Figs 1B, F View Fig , 2D, I View Fig ). It can be distinguished by the more transverse and more convex pronotum, and the generally reddish integuments, sometimes with darker head and pronotum ( A. atra sp. nov. is black, A. evax is black and metallic, and A. povilaensis sp. nov. is yellowish). Genitalia are also clearly distinguishable ( Figs 8C, G View Fig , 9E View Fig , 10A View Fig , 11B, F, L, P View Fig ).
Etymology
The name is a Latinized adjective referring to the distinctively transverse pronotum of the species.
Type material
Holotype
NEW CALEDONIA: ³, Mt Koghi , 400–600 m, [-22.17833 166.50667], Feb. 1973, N.L.H. Krauss leg. ( BPBM). GoogleMaps
Paratypes
NEW CALEDONIA: 3 ³³, 1 ♀, same data as the holotype ( BPBM).
Description of the holotype (³)
Body thickset, moderately convex ( Fig. 2I View Fig ); LB = 2.23 mm; maximum pronotal width at base (WP = 0.94 mm); maximum elytral width at basal third (WE = 1.17 mm). Dorsum light brown, non-metallic. Frons and vertex very finely microreticulate and sparsely punctate; head grooves weakly impressed, not continued to postantennal region; genae and frontal carina short; antennae slightly longer than ½ body length ( LAN = 1.30 mm; LAN/LB = 0.58), basally yellow, gradually and slightly darker toward apex; LA:100:82:54:73:82:91:100:91:91:91:136.
Pronotum trapezoidal, clearly transverse (LP 0.50 mm; WP/LP = 1.88), laterally straight ( Fig. 5D View Fig ); anterior angles distinctly prominent; antebasal transverse sulcus shallow, slightly sinuate, with visible lateral fovea; pronotal surface finely microreticulate, with very small and dense punctuation. Elytra moderately elongate (LE = 1.76 mm; WE/LE = 0.66), laterally clearly arcuate; punctuation quite small, but distinctly larger than on pronotum; interstriae flat, very finely microreticulate. Anterior and middle legs and hind tarsi yellow, hind femora and tibiae light brown; first pro- and mesotarsomeres moderately dilated; adhesive setae present on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter light brown; last abdominal ventrite laterally clearly incised, without special preapical impressions. Median lobe of aedeagus (LAED = 0.92 mm; LE/LAED = 1.91) ( Fig. 10A View Fig ) in ventral view laterally parallel at basal half, then slightly tapered; apex triangular with rounded tip; ventral sulcus complete, wide and deep for most of its length; in lateral view median lobe bent at basal third, then straight; dorsal ligula from half length to apical part of median lobe of aedeagus, narrow.
Biometry Male (n = 3; range): 1.54 Ĺ LE Ĺ 1.76 mm; 1.02 Ĺ WE Ĺ 1.17 mm; 0.42 Ĺ LP Ĺ 0.50 mm; 0.78 Ĺ WP Ĺ
0.94 mm; 1.20 Ĺ LAN Ĺ 1.30 mm; 0.87 Ĺ LAED Ĺ 0.92 mm; 1.95 Ĺ LB Ĺ 2.23 mm; 3.52 Ĺ LE/LP Ĺ 3.67; 1.24 Ĺ WE/WP Ĺ 1.31; 1.83 Ĺ WP/LP Ĺ 1.88; 0.65 Ĺ WE/LE Ĺ 0.66; 0.58 Ĺ LAN/LB Ĺ 0.62; 1.76 Ĺ LE/LAED Ĺ 1.91.
Female (n = 1): LE = 1.84 mm; WE = 1.24 mm; LP = 0.52 mm; WP = 0.96 mm; LAN = 1.22 mm; LSPc = 0.18 mm; LB = 2.35 mm; LE/LP = 3.54; WE/WP = 1.29; WP/LP = 1.85; WE/LE = 0.67; LAN/ LB = 0.52; LE/LSPc = 10.00.
Paratypes very similar in shape sculpture, and color to the holotype. One specimen with darker head and pronotum. Spermatheca ( Fig. 11P View Fig ) with pear-shaped basal part; collum about twice as long as apical part, thickset, clearly tapered toward apical part; ductus thickset, apically inserted (distal part missing).
Distribution
Endemic to Mt Koghi, Southern Grande Terre ( Fig. 15A View Fig ).
