Remarks.

The type series of C. montana Jolivet, Verma & Mille in the MNHN collection includes representatives of two species, most of them belonging to this distinctive taxon, but also some representatives of the species that we recognize in this work as C. imperiosa sp. nov. Both species, among the largest in the genus and among New Caledonian Eumolpinae (Table S 2), are easily recognizable by a suite of characters, of which most notable would be the presence of effaced humeri in C. montana (Fig. 5 a View Figure 5 ), prominent in C. imperiosa , and a very short metaventrite in C. montana (Fig. 5 c View Figure 5 ) compared to C. imperiosa . Distinguishing the species is not problematic, but at the time of the genus and species descriptions their differences were overlooked and mixed in a hybrid description highlighting characters of one or the other species, which is not useful to recognize any. For example, in the genus characterization, the description of thoracic ventrites corresponds to C. imperiosa , while that of elytra or the actual spermatheca fit C. montana , and the description of hind wings would represent the former, because the latter is most likely brachypterous.

The body plan of C. montana and its sister, C. robusta sp. nov., is rather different compared to most other Cazeresia , and the differences may be related to their adaptation to high elevation. They have typical features of apterous, lapidicolous species, including the absence of humeri and a very short metaventrite, a trait usually associated to brachyptery in Coleoptera (e. g., Smith 1964; Beutel 1992). In any case, their sclerotized reproductive organs have all the features typical of the genus. Here we illustrate for comparison the penis (Fig. 9 b View Figure 9 ) and spermatheca (Fig. 1 q View Figure 1 ) of C. montana . The first may be of assistance to distinguish this species from C. robusta , owing to the shorter apical blunt tooth in C. montana , apart from the generally finer dorsal punctation of this species.

Distribution.

The species was reported above 1450 m in the original description, in the rocky ascend to the summit of Mont Humboldt ( Jolivet et al. 2005). The additional record reported here is also from the type locality (Fig. 8 f View Figure 8 ).
