| contents | Ng & Mitra, 2019 (Crustacea, Decapoda, Goneplacidae): additional records and genetic differentiation of allied taxa. Prema, Mani Yang, Chien-Hui Ravichandran, Samuthirapandian Ng, Peter K L The goneplacid crab, Ng & Mitra, 2019, was originally described from West Bengal, India, in the northern Indian Ocean. Additional material of from off Tamil Nadu in the southeast of India revealed a high degree of size-associated variation in the structures of the anterolateral tooth of the carapace, chelipeds, and male and female pleons. In addition to an in-depth morphological examination of , this study also records the natural coloration of the species and conducts a genetic comparison (with mitochondrial COI and 16S rRNA genes) with its close relatives, (Miers, 1884) and Rathbun, 1914. Molecular comparison of with its morphologically closest congener, from northern Australia and the western Pacific, corroborates their status as separate species. The genetic sequence of , however, is similar to that of from the West Pacific, although these two species can easily be distinguished by distinct carapace and ambulatory leg characters. The present study provides some possible explanations for the genetic and morphological incongruence observed between and and highlights the need for a detailed molecular study for H. Milne Edwards, 1852, to appreciate the evolution of various morphological characters in the genus. |
