Genus Proturana Otte, 1987

Proturana Otte in Otte et al., 1987: 424.

TYPE SPECIES. — Euscyrtus subapterus Chopard, 1970 by original designation.

ILLUSTRATIONS. — Habitus: Fig. 15A . Male genitalia: Otte et al. 1987: fig. 20B.

EMENDED DIAGNOSIS. — Size small. Body shape distinctively elongate and thin, this shape reinforced by a colour pattern with many longitudinal stripes; legs I and II contrastingly short compared to long legs III. Head dorsum and face both convex, at right angle. Eyes small but somewhat protruding, widely apart from each other. Fastigium flat, narrow and elongate. Second tarsomeres flat and wide. TI without inner and outer tympana; three apical spurs. TII with three apical spurs. TIII with three inner and three outer apical spurs; outer spurs very short; median and dorsal spurs subequal on outer side; dorsal spur the longest on inner side; six to nine inner and five outer subapical spurs present in TIII distal half, short. TIII serrulation strong in TIII distal two third, more numerous on outer side. Basitarsomeres III short, shorter than tarsomeres 3; with apical spines and sometimes a few spines on outer side only. Cerci very short; often convergent at mid length, and thick at base. Coloration pale, with several longitudinal lines prolonged on head, pronotum and body; a wide brown band running from eye to abdomen mid length through LL; legs light yellowish brown with light brown dots and lines.

Male. FWs tiny, wider than long, partly overlapping; no stridulum, but a functional file made of very tiny teeth. HWs lacking in observed specimens. Subgenital plate long, pointing between cerci; lateral margins enveloping distally. Male genitalia: small; pseudepiphallic sclerite broadly triangular, distal margin raised and curved back on main sclerite; two turgescent and setose areas close to anterior margin; rami straight, strongly divergent; ectophallic fold wide and convex, separated from pseudepiphallic sclerite by a wide bilobated structure (fused pseudepiphallic parameres?).

Female. FWs very short, only slightly projecting from beneath pronotum. Ovipositor long, flattened dorso-ventrally, distinctly curved upwards then downwards, without a distinct apex.

DISTRIBUTION. — Endemic to New Caledonia, known from Dumbea ( P. subapterus ), Sarramea and Bourail (MNHN material).

HABITAT. — Proturana lives on grass in opened forest.
