Remarks

de Mazancourt et al. (2018c) recently redescribed C. appendiculata in detail. This species is known from Australia, Indonesia ( Flores, Obira and Sulawesi), Solomon Islands (Kolombangara, Isabel), Micronesia (Pohnpei), Palau and Vanuatu (Aneityum, Efate, Epi and Santo). This species lives in a typical brackish water environment (brackish water pool or lower part of rivers, near the estuary).

Fig. 2. Bayesian inference phylogenetic tree of the species studied. Numbers above branches are Bayesian posterior probabilities, numbers under branches are Maximum Likelihood bootstrap values. Results of the three species delimitation methods are indicated by the black bars on the right of the tree. Each bar represents a species recognized by the analysis.
