Description

A new species of Cyclosa is described under the name of Cyclosa bulla n. sp. using specimens collected from Thailand, Singapore and Brunei. Females of the species can be easily distinguished from other congeners by the shape of the abdomen, which has a globose posterior end. In contrast, males cannot be distinguished from those of Cyclosa bifida, which seems to be the most closely related species, even by the shape of the palpal organ. In this study, male specimens are identified by DNA barcoding.
