Redescription of Neodiaptomus Botulifer Kiefer and one of its related species (Calanoida: Copepoda)

Abstract

The problem associated with the systematics of a freshwater calanoida copepoda, Neodiaptomus botulifer Kiefer and one of its related forms was described . In order to solve this problem a new species, Neodiaptomus malaindosinensis is created in its place . The geographical distribution of these two calanoid species was briefly discussed .

Zoogeographical distribution of Southeast Asian freshwater Calanoida

“…It has N. botulifer features except the three points we just mentioned. We erected a new species of N. malaindosinensis (Lai & Fernando, 1978a) for the species which occurs in Thailand, Malaysia and Kampuchea. Its distributional range appears to overlap that of N. botulifer.…”

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

“…He reported that the same diaptomid had occurred in the Botanical Garden, Sai Gon, Vietnam, but he did not give any details of the female, and the description of the male is not detailed enough to enable accurate species diagnosis [23].…”

“…It was redescribed by Lai & Fernando (1978a) [23] and Reddy et al (1998) [34]. Reddy et al (2000) [35] amended delimitation of Mongolodiaptomus and transferred Neodiaptomus botulifer to the genus Mongolodiaptomus.…”

“…Based on the original descriptions of Daday (1906) [12] and Kiefer (1974) [20], the redescription of Lai & Fernando (1978a) [23] and the SEM pictures provided by Reddy et (Brehm, 1921) with native distribution in Hai Duong, Bac Giang provinces (Vietnam) and South of China (China). Shen & Song (1979) [45] considered N. handeli (Brehm, 1921) [11,17,32].…”

“…However, it is poorly known from Malaysia (10 species) [23,24,25,29], and Philippines (6 species) [8,28,36,60].…”
