Genus Anaxipha Saussure, 1874

Anaxipha Saussure, 1874: 370 .

TYPE SPECIES. — Gryllus pulicarius Burmeister, 1838 by subsequent designation (Rehn, 1905).

ILLUSTRATIONS. — Habitus: Fig. 3A ; Otte & Alexander 1983: fig. 161. Male genitalia: Otte et al. 1987: fig. 19. Calling songs: Otte & Alexander 1983: fig. 163.

EMENDED DIAGNOSIS FOR NEW CALEDONIAN SPECIES. — After Otte & Alexander (1983) and material preserved in MNHN. Head dorsum not fully flat between eyes. TI with an outer tympanum; inner tympanum lacking. FWs not hairy. HWs not developed. TIII with three pairs of long and thin alternate subapical spurs; only five relatively short apical spurs, ventral inner spur lacking.

Male. No dorsal gland on abdomen. FWs flat in lateral view. Stridulatory apparatus complete; mirror well-developed, most often diamond shaped. Apical field reduced. Metanotal glands present or lacking. Male genitalia: pseudepiphallus well-developed, symmetrical or almost so, and not hyperthelic; distal pseudepiphallus with two lateral long and thin lobes, and two shorter median ones; on each side, median and lateral lobes separated ( Anaxipha undescribed species) or not ( Anaxipha caledonica Otte, 1987 ) by an additional thin process; distal margins of lobes plain ( Anaxipha caledonica, Otte et al. 1987 : fig. 19B) or serrated ( Anaxipha undescribed species), resembling some species of Vanuaxipha Otte & Cooper, 2007 ; pseudepiphallic parameres symmetrical, flat.

Female. FW length and colour as in males. Ovipositor: distal margins of dorsal and ventral valves highly crenulated (see Otte et al. 1987: fig. 19C).

DISTRIBUTION. — World-wide. Known in New Caledonia by only one species from Grande Terre, on the western coast near Koumac ( A. caledonica ). Additional material attests the presence of Anaxipha at Parc provincial de la Rivière Bleue in the South of Grande Terre and at the base of Mont Mou (MNHN).
