The collision of the Indian and Eurasian plates during the Eocene represents a major tectonic shift that significantly altered biotic dynamics and promoted species diversification across the Oriental region. To explain the diversification of taxa from the Indian subcontinent into Southeast Asia, two principal hypotheses have been proposed: the "Biotic-ferry" and "Step-stone" models. The subfamily Perittopinae, a lineage of semi-aquatic bugs comprising a single genus and 20 extant species, provides an ideal system for testing these hypotheses due to its disjunct distribution spanning the Indian subcontinent and Southeast Asia.

The sodium leak channel NALCN, a key regulator of neuronal excitability, associates with three ancillary subunits that are critical for its function: a subunit called FAM155, which interacts with the extracellular regions of the channel, and two cytoplasmic subunits called UNC79 and UNC80. Interestingly, NALCN and FAM155 have orthologous phylogenetic relationships with the fungal calcium channel Cch1 and its subunit Mid1; however, UNC79 and UNC80 have not been reported outside of animals. In this study, we leveraged expanded gene sequence data available for eukaryotes to reexamine the evolutionary origins of NALCN and Cch1 channel subunits.

Rhabdocoel flatworms of the family Typhloplanidae are predominantly found in freshwater and limnoterrestrial environments, with only a few species inhabiting marine and brackish water ecosystems. In this study, a flatworm was discovered in moist soil containing nematodes in the Guizhou plateau of southwest China for the first time. A new species, Zuo, gen.
