Genus Metioche Stål, 1877

Metioche Stål, 1877: 48 .

TYPE SPECIES. — Trigonidium vittaticolle Stål, 1860 by subsequent designation ( Chopard 1968).

ILLUSTRATIONS. — Habitus: Fig. 3C ; Otte & Alexander 1983: fig. 168. Male genitalia: See Hugel (2012).

EMENDED DIAGNOSIS FOR NEW CALEDONIAN SPECIES. — After Otte & Alexander (1983) and material preserved in MNHN. Macropterous or micropterous. Head dorsum flat between eyes. TI with an outer tympanum and an inner tympanum, or none. FWs not pubescent. HWs greatly developed well-beyond the body, or not.TIII with three pairs of long and thin alternate subapical spurs; only five relatively short apical spurs, ventral inner spur lacking.

Male. Dorsal gland present. Stridulatory apparatus lacking, even a file present; venation with few longitudinal veins. Male genitalia (see Otte & Alexander 1983: fig. 170; Hugel 2012): pseudepiphallus welldeveloped, symmetrical and not hyperthelic; distal pseudepiphallus with two lateral long and thin serrated lobes, and two very short median ones; pseudepiphallic parameres symmetrical, flat.

Female. FWs developed as in males. Ovipositor very feebly crenulated on distal margins of dorsal and ventral.

DISTRIBUTION. — According to Eades et al. (2016), Metioche is distributed worldwide and diversified mostly in South East Asia and Oceania. The material identified by Chopard (1970) and additional material collected since then attest the presence of the genus in New Caledonia.
