PARATYPES: 13 JJ 1 ♀, the same data as holotype but 15 Jul 1987, 700m ( QMBA, MHNG, PHKS). 2 JJ 1 ♀, FIJI: VANUA LEVU: Savusavu Saddle, 500 m, 26.X.1977, leg. G. Kuschel.

Description. Body ( Fig. 3 View Figs ) 2.1–2.2 mm long, maximum width of elytra 0.80–0.85 mm, brown. Head about 2.5–2.6 times as long as wide, eyes slightly protuberant. Antennae with terminal antonnomere 1.1 mm long. Pronotum 0.55–0.50 as short as head and about 1.15 times as wide as long. Elytra about 1.4–1.5 times wider than long at suture, sutural striae well-defined, parallel along whole length of suture.

Metaventrite with median, well-defined depression delimited by concave area between metacoxae. First visible sternite (IV) 3.5 times shorter than second (V), this one also 3.5 times as long as VI–VII combined.

Abdomen with the composite tergite very large, about six times as long as rest of dorsaly visible tergites. Profemora with median spurs, mesofemora with spurs located in basal third and with long and sharp apical spines, metafemora with larger, median spurs. Mesotibiae with minuscule apical spur, lacking spines. Aedeagus as in Fig. 8 View Figs , 0.45–0.49 mm long.

Sexual dimorphism. Female with the same spurs and spines on femora but the mesofemora are lacking long, sharp, apical spines, and with the metaventrite transversally convex, lacking any depressed area between metacoxae.

Etymolgy. The name refers to the long legs of this species.
