The freshwater Calanoida (Crustacea: Copepoda) of Thailand

Abstract

14 Species of freshwater Calanoida in Thailand are reported in this study. The most common species is Neodiaptomus botulifer. Most of these belong to the Southeast Asian species, the remainder are either Indian or East Asian copepods. The zoogeographical demarcation of copepods in Thailand is not very distinct due to its interconnecting riverine and reservoir systems as well as frequent flood. The peculiarity of the Thai Calanoida and their distribution is discussed in a Southeast Asia context. A taxonomic key to the Thai Calanoida is formulated.

First record of the Asian diaptomid Neodiaptomus schmackeri (Poppe & Richard, 1892) (Crustacea: Copepoda: Calanoida) in Europe

“…Lake Merhojes (42 m of maximum depth) is one of the deepest lakes of the Dumre plateau and it seems that it was not successfully colonized by the species. The aquatic environments in which we found N. schmackeri in Albania are shallow, permanent, eutrophic lakes (most of which addressed to aquaculture) with turbid waters, in accordance to what already documented, for instance, for the type locality in China (Poppe and Richard, 1892), for the reservoirs, fish ponds and permanent pools of Thailand (Lai and Fernando, 1981), Japan (Semura et al, 1986), Russia (Borutzky et al, 1991), and Taiwan (Young and Shi, 2011). Conversely the occurrence sites reported for India, are mainly turbid ephemeral pools rather than permanent lakes (Rajendran, 1971;Ranga Reddy, 1994).…”

“…In particular the spine on the article 15 of the male right antennula is confirmed to be one of the most variable feature of N. schmackeri. In fact, in the Albanian population, this spine can be absent or very small as in the Indian specimens described by Rajendran (1971), Bhattaracharya et al (1990) and Ranga Reddy (1994), or strong as showed for the Thai specimens described by Lai and Fernando (1981), the Japanese specimens described by Semura et al (1986), the Russian ones by Borutzky et al (1991), and those from Taiwan depicted by Young and Shih (2011). Among the Albanian specimens, we have observed this wide variability even in the population of the same lake and in the same date.…”

Cyclopoid and calanoid copepod biodiversity in Indonesia

Furthermore, we briefly revise the descriptions and classification of several copepod taxa from the lakes of Sulawesi, and provide them with molecular-genetic identifications (barcodes) for future phylogenetic studies.…”

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

“…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].…”

“…Therefore, we place the Vietnamese specimens as two distinct species. Distribution: China (Yunnan) [45,48]; Cambodia [9]; Thailand [37]; Indonesia [6,22]. [19].…”
