In external morphology, <i>C. cytherea</i> is almost indistinguishable from <i>C. davaoensis</i> Ward, 1941 and <i>C. crispipleopa</i> Dai, Yang, Song & Chen, 1986. Dai et al. (1986: 342) provided a table of the distinguishing features of <i>C. crispileopa</i> and <i>C. cytherea</i>: i.e., carapace, front, second anterolateral tooth, and G1. However, examination of the extensive collection of this species from Christmas Island indicates that these features are variable. Even the G1, which is useful for identification of other chlorodielline species, varies from the distally “curled” <i>C. crispipleopa</i> form (e.g. RL 1) (Dai & Yang, 1991: 341, fig. 169(1)) to the distally “hook-shaped” <i>C. cytherea</i> form (e.g., RL 6, RL 17) (Dai & Yang, 1991: 341, fig. 169(4)). A G1 figure of <i>C. davaoensis</i> was not provided by Ward (1941) or since the original description. It is unclear whether these three species are distinct. Examination of the type specimens and material from the type localities is necessary to resolve this problem, and a systematic revision of this species complex and the Chlorodiellinae is being undertaken (RML & PKLN, in prep.). For the moment, the earliest name, <i>C. cytherea</i>, is attributed to the specimens reported here as they fit the original description of Dana (1852).</p><p>New CI, CK record.</p> |
