The paper presents results on tree snails based on samples collected from various parts of Vietnam during the period of 2008–2022. As a result, 14 Amphidromus species were recorded, which increased the diversity of the genus in Vietnam to a total of 27 species. Four species were new country records including Amphidromus atricallosus perakensis, Amphidromus leucoxanthus, Amphidromus perversus natunensis, and Amphidromus areolabiatus. Almost all 14 species were found in the south, while only Amphidromus roseolabiatus was recorded in the north.

Rogerella aydimi Gallardo-Garcia and Serra-Kiel was described from the Priabonian Haluf Member of the Aydim Formation, Oman. Based on new finds from the Bartonian Hoya Formation of SE Turkey and the Jahrum Formation of Iran, its taxonomic status is discussed herein. It is concluded that it represents a species of Dictyoconus with a simple subepidermal network (1 rafter, 1 intercalary beam) below a thin epiderm. The stratigraphic range of D. aydimi known thus far is Bartonian-Priabonian or Shallow Benthic Zone 17– 20. The distribution of D.

In this work, we review various PhCs detected in water treatment plants. We propose that fungi, particularly white-rot fungi (WRF), can be used for their bioremediation and describe the main mechanisms used for degrading this type of emerging pollutants; however, we also highlight the need to prospect for new fungal models.

Among 14 species of forest skinks (genus Sphenomorphus) in Vietnam, seven were recorded from southern part of the country. Shea's forest skink, S. sheai, was described from Kon Tum Plateau based on a single female. Similarly, the tridigital forest skink, S. tridigitus, was also described based on a single putrid and desiccated specimen found dead on a road in Bach Ma; specimens collected recently in Laos did not fully agree with the original description.
