An Annotated Checklist of Algae from the Order Synurales (Chrysophyceae) of Viet Nam

Abstract

This paper presents an annotated list of the Mallomonas and Synura taxa (order Synurales, class Chrysophyceae) found in Viet Nam. This list is based on materials from long-term studies (from 2008 to 2020) of 371 freshwater localities in 18 provinces in the country. A total of 67 taxa (morphotypes) of the genus Mallomonas and 7 of the genus Synura were reported. For each species, the range of abiotic environmental parameters under which they were found is given, as well as comments on the distribution of these taxa within Viet Nam and the tropical region.

“…5d). The species was commonly found not only on the Australian continent (Croome et Tyler 1985), but also in Vietnam (Gusev et al 2023) and Indonesia (Kapustin and Gusev 2019). Mallomonas plumosa was a frequent inhabitant of waterbodies in this study.…”

“…Mallomonas fragariformis (Fig. 2i-j) belongs to the Mallomonas mangofera species complex and was also recently described from tropical Vietnam ) and so far found at 8 localities in central and southern Vietnam (Gusev et al 2023) and on the Island of Java (Indonesia) as Mallomonas sp. 1 (Kapustin et Gusev, 2019).…”

“…Mallomonas minuscula (Fig. 4j) was described from Vietnam (Gusev et al 2019), and previously sampled from only a few Vietnamese sites (Gusev et al 2023). We found this species at a single location: pool on Pryde Creek (loc.…”

“…There are several large circular pits with a pore at the bottom along the inner margin of the posterior submarginal rib, whereas there is only a single pit in M. favosa f. favosa. Forma 2 was common in Malaysian habitats and was also observed in Kulukuluku Billabong in the Northern Territory of Australia and in Vietnam as M. favosa f. gemina (Gusev et al 2023). From the preliminary analysis of molecular data of M. favosa-like species from around the world (Škaloud pers.…”

“…Mallomonas morrisonensis (Fig. 2k-l) has been described from temperate Tasmania (Australia; Croome et Tyler 1983) and appears to be a common species in several tropical/subtropical localities, e.g., Brazil (Franceschini et Kristiansen 2004), Malaysia (Durrschmidt et , or Vietnam (Gusev et al 2023). However, Furlotte et al (2000) reported the species from other temperate Australian sites, including Qeensland.…”
