“…Of the 30 calanoid species, 27 diaptomid species were reported from Southeast Asia [3]. 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].…”

The diversity, distribution, and checklist of diaptomid copepods from various freshwater ecosystems throughout Thailand are presented, based on data from our biodiversity projects during 1993–2019 and literature reviews. Thailand has one of the most diversified diaptomid fauna in the world, with 42 species identified from 2150 localities (4962 samples). Mongolodiaptomus has the highest species richness with ten species, followed by Tropodiaptomus with seven species. Among these, eight taxa (Arctodiaptomus sp., Mongolodiaptomus pectinidactylus, Neodiaptomus meggitti, Tropodiaptomus hebereri, T. lanaonus, T. oryzanus, T. ruttneri, and Paradiaptomus greeni) are new to the fauna of Thailand. The rare P. greeni, which predominantly occurs in Africa, is also a new record for Southeast Asia. The most frequently encountered species were Mongolodiaptomus botulifer, Phyllodiaptomus praedictus, M. calcarus, M. dumonti, M. malaindosinensis, Vietodiaptomus blachei, Phyllodiaptomus christineae, Eodiaptomus sanoamuangae, Neodiaptomus yangtsekiangensis, E. draconisignivomi, T. vicinus, and Heliodiaptomus elegans. Twelve species appear to be endemic to Thailand, and eight species occur only in the countries belonging to the lower Mekong River Basin (Thailand, Cambodia, Laos, and Vietnam). The uniqueness of the Thai diaptomids is a high degree of co-occurrence of four to seven species in the same localities. Comments on the taxonomic status of the species recorded are provided. In addition, the taxonomic validity of Mongolodiaptomus malaindosinensis is discussed.

“…Sanoamuang and Watiroyram, 2018. These three species were found in the same study area (Sanoamuang and Sivongxay, 2004;Sanoamuang and Watiroyram, 2018). M. mekongensis has a wider distribution and occurs in Laos, Thailand, Cambodia, and Vietnam, while E. phuvongi inhabits Laos (Khammouane and Savannakhet Provinces) and Thailand (Ubon Ratchathani Province).…”

A new calanoid copepod, Allodiaptomus nongensis n. sp., is herein described based on samples collected from the Xe Lanong River (a tributary of the Mekong River), and 13 other localities in Central Laos. This is the sixth species of the genus Allodiaptomus Kiefer, 1936. The other five members in the genus were recorded from India, South China, Cambodia, Thailand, and Vietnam. The features that stand out in the new species are in the male: the right caudal ramus has a large, biacuminate, conical process proximally, and the Exp-2 of the right P5 has a hook-shaped principal spine proximally. The new species is abundant in both temporary and permanent waters, but is restricted to Savannakhet Province. This Laotian endemic copepod is referred to by local people as “Pa Khayong”, which means tiny fish. Since high densities of this copepod can be found in the dry season (December until May), several man-made copepod traps are placed by local people along the river banks in Muang Nong District. Interestingly, large concentrations of individuals (body length: ~1 mm) belonging to the new species are harvested and consumed by these villagers. Additional information about this species and the copepod fisheries by local people in this area is provided herein. In this paper, the reassignment of Allodiaptomus rarus to the genus Mongolodiaptomus is proposed.

“…In Southeast Asia, this family has been studied well in Thailand (32 species) [16,27,34,35,37,40,41,42,43], and Indonesia (17 species) [1,7,8,18,21,22]. However, it is poorly known from Malaysia (10 species) [23,24,25,29], and Philippines (6 species) [8,28,36,60].…”

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.
