Genus Cardiodactylus Saussure, 1878

Cardiodactylus Saussure, 1878: 657 .

TYPE SPECIES. — Platydactylus novaeguineae de Haan, 1844 by subsequent designation ( Kirby 1906).

ILLUSTRATIONS. — Habitus: Fig. 15C . Male genitalia: Robillard & Ichikawa 2009: fig.4. Calling song: Robillard & Ichikawa 2009: fig. 7.

DIAGNOSIS. — After Robillard & Ichikawa (2009). Large, fusiform species, with long FWs, HWs and cerci in both sexes. Coloration variegated, with yellow, whitish, brown and black; palpi yellow to white, with or without a brown apical ring on joint 5. Eyes slightly protruding. Fastigium as wide as scape, thus relatively narrow compared to other eneopterine genera. Pronotum transverse. TI with an inner and an outer tympana.

Male. Stridulum complete; harp longer than wide, with two strongly bisinuated, oblique veins; mirror well delimited, more or less clearly separated from apical field; apical field elongate with several cell alignments. Male genitalia: pseudepiphallic sclerite very long, greatly narrowed at mid length, setose laterally and ventrally, with two high dorsal crests partly fused dorsally; rami short and wide.

Female. Ovipositor long, apex lanceolate and flattened laterally. Female genitalia: copulatory papilla with rounded sclerotized base and apex.

CALLING SONG. — The call of C. novaeguineae (de Haan, 1844) is complex, with two different types of echemes. The dominant frequency is carried on the third harmonic ( Robillard & Ichikawa 2009).

DISTRIBUTION. — Cardiodactylus is highly diversified in the western Pacific; it is known in New Caledonia by only C. novaeguineae , a widely distributed species in Oceania ( Robillard & Ichikawa 2009).

HABITAT. — Cardiodactylus novaeguineae is restricted to opened forest in coastal areas, where it forages from afternoon to night on vegetation ( Robillard & Ichikawa 2009).
