Median carina close to pronotal surface; pronotum strongly bulging in middle. In lateral view, the anterior portion of median carina concave. Pronotal apex wide. DISTRIBUTION. — Widely distributed in New Caledonia. HABITAT. — Found at night in humid forests, generally on living trees with smooth bark, 1 m to 2 m high. REMARK Many specimens are reported here under H. orphania, but it is possible that there are multiple similar species. The type series consists of four specimens (two of each sex) with no precise collection localities. The males have a more dome-like pronotum, i.e., the middle part forms a distinct bulge. In females, this feature is much less perceptible and the caudal part of pronotum lowers more gradually. This seems to be the case of sexual dimorphism as we have observed the same in our specimens. The anterior margin of pronotum being distinctly concave seems to be a stable character and we use it to diagnose the species. There are, however, some populations in which the anterior margin of pronotum is only slightly concave, which we still consider H. orphania, but they may represent a completely separate species. Hyperyboella is an incredibly morphologically diverse genus with unclear distribution across all of New Caledonia. More material or molecular studies are needed to elucidate the phylogeny of this genus.
