Distribution. New Caledonia ( New Caledonia, Loyalty Is).

Comments. The species was described from New Caledonia. The types were redescribed by Stein (1907a) and were reviewed, with lectotype designation, by Pont (2000: 7). Recorded from several localities by Shinonaga et al. (1991).

The very large series examined showed a remarkable variation in some characters, both in colour and in chaetotaxy. Postpedicel colour varies from basal half yellow to wholly dark brown; abdomen colour varies from wholly yellow to syntergite 1+2 and tergites 3–4 largely brown, or just with a faint shadow of these marks; some specimens have the abdomen a little shiny. Furthermore, the two black stripes on scutum vary from thin to rather broad, and the leg chaetotaxy is also not constant, especially on the hind femur where some specimens have anteroventral setae only on apical half or third while others have a complete anteroventral series of long setae. The size ranges from 4 to 7 mm. There are no constant combinations of these characters among the specimens, which might indicate that an evolutionary diversification process is still underway (see discussion).
