Morphological characteristics were compared between three recorded species of rounded caudal fin Oreonectes and specimens collected from Guan'an of Guangxi. The results showed the Oreonectes sp. from Guan'an was distinguished from O. anphthalmus. Although some morphologic differentiations existed among Oreonectes sp., O. polystigmus, and O. platycephalus, their differentiations were not enough to distinguish between them. Consequently, we used multivariate morphometrics to determine their morphologic differentiation. Twenty-six frame characteristics and 20 general characteristics of 63 specimens were measured. The results of the Principal Component Analysis showed that Oreonectes sp. and O. polystigmus, and Oreonectes sp. and O. platycephalus occupied obviously different areas in the scatter plot. It is suggested that the specimens collected from Guan'an may be a cryptic new species of Oreonectes. However, its taxonomic status should be decided by evidence from anatomical and molecular biological studies.

- - A new genus of leafhoppers called Dutrapona has been identified within the Gyponini tribe, including three new species from Central and South America.
- - The newly described species are Dutrapona tenuis from Costa Rica, Dutrapona reticulata from Ecuador, and Dutrapona zahniseri from Panama, with Dutrapona tenuis being the type species.
- - Dutrapona can be differentiated from other genera in the Gyponini tribe by its unique physical traits, such as specific shapes and positions of ocelli, distinctive features of the crown, and characteristics of the male reproductive structures.

- A new species of bagrid catfish called Pseudomystus tuberosus has been identified in the Kahayan River drainage in Borneo.
- This species is characterized by a distinctively humped dorsal profile and a body covered in rounded tubercles, differentiating it from other related species.
- Pseudomystus tuberosus is closely related to P. vaillantii but can be recognized by its smaller eye size and slimmer caudal peduncle, while the classification of another species, P. carnosus, is also revised.
