“…Mallomonas lamii (Figure 3A), M. loricata (Figure 3B), M. minuscula (Figure 3G), and M. paragrandis (Figure 3J) were recently described in Vietnam and are widespread throughout the country [46,47,55,57,59]. Mallomonas loricata scales were found earlier in Malaysia and Singapore and identified as M. matvienkoae [28].…”

“…These studies have revealed a very rich flora from the order Synurales, including 57 taxa from genera Mallomonas and Synura. Indeed, 19 new species from the genus Mallomonas [40,[45][46][47][48][49][50][51][52][53][54][55][56][57][58][59] and one Synura species [60] were described in these studies. However, the northern part of Vietnam, which differs in hydrology, climate, and anthropogenic impact from the Central and Southern provinces, is lacking sufficient descriptive studies.…”

The present paper focuses on the flora of synuralean algae from four northern provinces in Vietnam: Bac Kan, Hanoi, Ninh Binh, and Thanh Hoa. Fifty-five water bodies were studied, including territories within national parks Ba Be, Ba Vi, Cuc Phuong, Ben En, and Trang An Wetland—The World Cultural and Natural Heritage and Van Long Wetland Nature Reserve. Samples were obtained from natural lakes and wetlands, artificial reservoirs and ponds, and small temporary water bodies. Electron microscopy allowed for the discovery of 39 taxa, 37 of which belonged to the genus Mallomonas and two to the genus Synura. Six taxa of the genus Mallomonas and two taxa from the genus Synura were not identified to the lower rank. Five taxa are reported for the first time in Vietnam. The most diverse flora was observed in natural protected water bodies. Eutrophic and hypereutrophic water bodies, which were prevalent in the study area, had a reduced number of selected species.

“…Information about diversity of algae from the order Synurales in the Northern Vietnam has also been published recently, including the description of two new species [76][77][78]. In addition, a number of new species for science have been described from individual regions of the country [71,[76][77][78][79][80][81][82][83][84][85][86][87][88][89][90][91]. However, Central Vietnam, except for certain areas of the Khanh Hoa province, has not yet been studied.…”

This paper focuses on the flora of scale-bearing chrysophytes from eight provinces located in the central part of Vietnam. Khanh Hoa, Phu Yen, Binh Dinh, Thua Thien Hue, Quang Tri, and Quang Binh provinces are located in the coastal area of Vietnam. Lam Dong and Dak Lak provinces represent mountain territories with an elevation of 500–2000 metres above sea level. In total, 212 water bodies of different origins were studied. Samples were obtained from swamp areas, lakes, rivers, reservoirs, ponds, and small temporary water bodies. In total, 76 taxa were identified by electron microscopic observations of samples. A total of 54 taxa were found in the mountainous provinces, while 73 were found in the coastal provinces. Of these, 51 species are common for both areas. The most diverse was the genus Mallomonas with 66 species, varieties, and forms; followed by Synura with 7 taxa; Chrysosphaerella with 2; and Spiniferomonas with 1. Seven taxa of the genus Mallomonas were not identified to the lower rank. All these unidentified specimens may potentially represent new species for science. Ten taxa are reported for the first time in Vietnam.

“…Nevertheless, they are at present far less reported from low latitude areas, as most of the stomatocysts are reported from temperate and cold zones. During the survey of silica scaled chrysophytes from tropical and subtropical areas, such as southern China (Wei et al 2013(Wei et al , 2014Nĕmcovà et al 2015), Vietnam (Gusev & Martynenko 2022;Gusev et al 2015Gusev et al , 2016Gusev et al , 2017Gusev et al , 2018Gusev et al , 2019Gusev et al , 2020Gusev et al , 2021, Indonesia (Kapustin et al 2019) and Cameroon (Piatek & Lukaszek 2016), more and more new species were reported. It confirmed that mountain lakes and generally water bodies in poorly studied tropical and subtropical areas from East Asia are rich with chrysophytes and many new species can be found there.…”

During a survey of the chrysophyte stomatocyst flora in surface sediments of 34 lakes in Three Parallel Rivers of Yunnan Protected Areas, 14 new stomatocysts were observed. These new cysts were described based on scanning electron microscopy (SEM) observations. Their morphology was compared with the most similar morphotypes worldwide. The obtained records improve our knowledge on the stomatocyst diversity in low latitude high mountain lakes of the world.
