C45E9575604B54F3BE165DF26B55FF83.taxon	etymology	Etymology. The specific name " Cryptosemelus betarmon " is from the Greek word meaning a dancer and refers to the fidgety movements or dance-like movements of living semislugs found in the field after being disturbed.	en	Pholyotha, Arthit, Sutcharit, Chirasak, Panha, Somsak (2021): Rediscovering the dancing semislug genus Cryptosemelus Collinge, 1902 (Eupulmonata, Ariophantidae) from Thailand with description of two new species.

C45E9575604B54F3BE165DF26B55FF83.taxon	distribution	Distribution, habitat, and behavior observations. Cryptosemelus betarmon sp. nov. is restricted to the limestone outcrops in Prachuap Khiri Khan Province, Thailand (Fig. 1). During the rainy season, but with low precipitation, the semislugs were found inactive under the decaying leaf litter or sometimes inside the hole of decaying wood. This semislug species also moved quickly as well as quickly flipping and wagging its tail to escape after being disturbed. The data on its natural enemies are unknown, but the carnivorous snail, Haploptychius sp. (Streptaxidae), was found at a high abundance in the type locality.	en	Pholyotha, Arthit, Sutcharit, Chirasak, Panha, Somsak (2021): Rediscovering the dancing semislug genus Cryptosemelus Collinge, 1902 (Eupulmonata, Ariophantidae) from Thailand with description of two new species.

6A656FA521DB5D36AAC55A7F120FBA72.taxon	distribution	Distribution, habitat, and behavior observations. Cryptosemelus gracilis can be found in Satun, Yala, Songkhla, and Pattani Provinces in southern Thailand (Fig. 1). We searched after rain and found the semislug populations normally hiding under the slope of rocks or the tree trunks, and sometimes climbing on the rocks or low branches of plants. When the semislug are disturbed, they escape by quickly flipping and wagging their tail, and then falling on the floor. Information on its natural predators and parasites remains scarce, but the carnivorous slug genus Atopos and streptaxid snails were found sympatrically with this semislug.	en	Pholyotha, Arthit, Sutcharit, Chirasak, Panha, Somsak (2021): Rediscovering the dancing semislug genus Cryptosemelus Collinge, 1902 (Eupulmonata, Ariophantidae) from Thailand with description of two new species.
