An annotated checklist of the family Diaptomidae Sars, 1903 (Copepoda, Calanoida) in Vietnam

Abstract

ABSTRACT:The paper presents an updated checklist of Diaptomidae in Vietnam, based on literature reviews and on our own data from voucher specimens deposited in the Institute of Ecology and Biological Resources (IEBR), Hanoi. Taxonomic status of diaptomid species occurring in the country is revised. A total of 13 genera and 29 species have been recorded; of those 29 species, 8 are endemic, and other 8 are newly added to the latest fauna list in 2001. Remarks on nomenclature and taxonomic issues are supplemented with information on the geographical distribution of the species within and outside Vietnam.

Diversity, Distribution, and Habitat Occurrence of the Diaptomid Copepods (Crustacea: Copepoda: Diaptomidae) in Freshwater Ecosystems of Thailand

“…Allodiaptomus raoi Kiefer, 1936 is an uncommon species that occurrs in lakes, res-ervoirs, rivers, and rice fields in the northeast of Thailand. It was originally described in south India [37] and has been found in Cambodia [23], Vietnam [32], and China [38].…”

“…It is widely distributed in the northeastern region but sporadic in the northern, eastern, and western regions. D. javanus has been found in Cambodia [23], Indonesia [31], Vietnam [32], and southern China [38]. Dentodiaptomus orientalis Sanoamuang and Watiroyram, 2021 is a newly described taxon, recorded from five and six localities in the floodplain of the lower Mekong River Basin in Thailand and Cambodia, respectively [44].…”

“…In Thailand, it is a common species occurring in permanent water bodies such as canals, rivers, lakes, reservoirs, and swamps in the northeastern, central, eastern, and western parts of the country [10]. This species appears to be a widely distributed diaptomid in the lower Mekong River Basin, as it is known from Cambodia [46], Laos [47], and Vietnam [32].…”

“…It is a common species and has been found mostly in permanent water bodies, but sometimes in temporary ponds in the north, northeast, and west of Thailand. It has been reported from Cambodia [23], Bangladesh [50], Vietnam [32], and China [38].…”

“…Most of the studies were conducted in Thailand since 1994 [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], while a few investigations have been documented in Cambodia [20,21,23], Laos [16,20,24], Malaysia [25][26][27], Singapore [28], the Philippines [29,30], and Indonesia [31]. A few studies were conducted in Vietnam [20], but most of the publications were published in Vietnamese with an English abstract [32].…”
