Nomenclatorial note. The name was dedicated to the collector Jules Sébastien César Dumont d’Urville. Dejean (1825) in the original description named his new species as “ durvillei ”, the only valid name of this taxon, while any other of the above listed spelling must be considered “incorrect subsequent spelling”, according to the Article 32 / Original spelling / Article 32.5.2.3 / Examples. “ d’urvillei becomes durvillei ” (ICZN 1999).

Type locality. “ Nouvelle Guinée ”.

All specimens identified and labelled as Calomera durvillei by authors of the present paper, those in IRSNB and MFNB by the first author.

Differential diagnosis. Calomera durvillei is mostly immediately recognizable due to its pattern of elytral maculation which is in majority adults reduced to small lateral maculae tightly adjacent to outer elytral margin and little central spot (Figs 203–204, 210–213); however, adults with extremely dilated maculae, consisting of entire humeral lunule (as in HT Figs 200–201 and wide, continuous lateral band also occur (Figs 214–215). Densely setose genae and proepisterna are shared with C. paradecemguttata sp. nov., which is, however, clearly distinguished by the pattern of its elytral maculation and indentation on lateral edges of the apical portion of male aedeagus in its dorsal (and ventral) view (in contrast to the continuous lateral edges in the aedeagus of C. durvillei).

For the description see Dejean (1831), but it does not cover entire variability of elytral maculation, because the holotype (Figs 200–201) has its maculation wider than usually, intermediate between the extremely wide maculation demonstrated in Figs 211–212.

Body 11.5–14.7 (HT 12.4) mm long, 4.05–5.20 (HT 4.50) mm wide.

Specimens with darkened elytral maculation can be confused with C. sanguineomaculata, as for instance the above-listed female in MFNB.

Distribution. Calomera durvillei inhabits western part of Indonesia, spreading through Irian Jaya to Papua New Guinea, to the Bismarck Archipelago (New Britain, New Ireland, Duke of York, Gardner, Nusa. Occurrences in Moluccas listed by Wiesner (2018, 2020) are obviously misidentifications of C. paradecemguttata sp. nov. It must be noted here that C. durvillei is sometimes confused also with others of the species-complex in museum collections. Darlington (1962) mentioned that C. durvillei (treated by him as C. decemguttata durvillei) is common and widely distributed in New Guinea. The historical specimen (IRSNB ex collection of M. Maindron) with “Dorey 1887” on its label, comes from an area near the village and harbour of Dorey in western Papua New Guinea, where Dumont d’Urville and later also A. R. Wallace collected during their famous journeys. Historical specimens (MFNB) labelled “Neu Mecklenburg” or “Lamasong”, come from today’s New Ireland, a volcanic island in the Bismarck Archipelago (Papua New Guinea). Another historical specimen (MFNB) with “Peterhafen” on its label comes from Vitu Island (also spelled “Witu”) lying in the Vitu Island group in the Bismarck Sea (part of the West New Britain Province), Papua New Guinea, formerly part of Deutsch Neu Guinea with the Peterhafen coconut palm plantations (data adapted from Wikipedia and Britannica). Hornabrook (1988), who treated this species as Lophyridia decemguttata urvillei, mentioned that it is common in New Guinea, inhabiting exposed clay surfaces, found on roads, airstrips and some well-drained gently sloping clay banks where adults “may occur in scores and take off and come down few meters ahead when disturbed”. He never saw this species above 900 m in altitude, but found it most frequent at about 400 m above sea level in all suitable localities visited at this altitude.

Cassola (1987a) listed a great number of records from Irian Jaya and Papua New Guinea, one male from the Bismarck Archipelago, and surprisingly one male from Tamana Island, which is the smallest island of the remote Gilbert Islands, lying 4500 km northeast from Australia, thus this specimen (MFNB) might have been mislabelled.
