Description

See de Mazancourt et al. (2019b).

Habitat

This species is largely rheophile and prefers fresh and well-oxygenated waters from the lower course to the higher course of rivers.

Colour pattern

The live general colour of the body is yellowish and slightly translucent. Numerous red spots are visible all over the body. Sometimes, a lighter longitudinal dorsal band is present stretching from the rostrum to the telson (see de Mazancourt et al. 2019b).

Distribution

This species seems to have a wide distribution: Solomon Islands (Malaita and Choiseul), Fiji, Samoa, Cook (Rarotonga) and French Polynesia (Society and Austral archipelagos).

Remarks

Recently de Mazancourt et al. (2019b) have revised the species of the C. weberi   group from Polynesia. Contrary to what Edmondson (1935) wrote, C. weberi   does not occur in Polynesia but four other species of the C. weberi   complex. Among these species, one also occurs in the Solomon Islands: C. tupaia   . Curiously, although the dorsal teeth of the rostrum are situated all along its length, with sometimes 1–3 of them situated on the carapace behind the orbital margin in French Polynesia, in Samoa (Upolu) and the Cook Islands, specimens from the Solomon Islands have dorsal teeth situated considerably anterior to the orbital margin with none of them situated on the carapace behind the orbital margin (see Fig. 16 View Fig ).
