Tropical species of Kurzia (Crustacea, Cladocera) with a description of Kurzia brevilabris sp.nov.

Abstract

Kurzia longirostris (Daday) from throughout the tropical region was examined, together with a review of all previous records worldwide. It is clear that what was considered K. longirostris consists of two species in the Oriental region. This includes a new species, Kurzia brevilabris sp.nov. It differs from K. longirostris in the head pore configuration, the structure of the labrum, and the arrangement of the submarginal setules along the posteroventral corner of the carapace. A detailed description of the species is given. A detailed redescription of K. longirostris is given based on the types and material from Sri Lanka. The morphological variations observed in different populations of the tropical region are also included in the description.

Cladocera (Crustacea: Branchiopoda) of Vientiane province and municipality, Laos

“…Kurzia brevilabris Rajapaksa & Fernando, 1986. Common species in SE Asia (Rajapaksa and Fernando, 1986) and its presence in Laos was expected.…”

Cladocera (Crustacea: Branchiopoda) of Cat Tien National Park, South Vietnam

“…Found in small forest and village ponds, Bau Sau and Bau Chim lakes, more abundant in autumn than in spring. For a detailed description see Rajapaksa and Fernando (1986b). Species of Oriental region (Rajapaksa and Fernando, 1986b).…”

“…For a detailed description see Rajapaksa and Fernando (1986b). Species of Oriental region (Rajapaksa and Fernando, 1986b). The first record for Vietnam.…”

“…Found in small forest ponds and single forest stream in spring only, more rare than K. brevilabris. For a detailed description see Rajapaksa and Fernando (1986b). Distributed in Australia, tropical Asia and Africa.…”

Notes on some rare and interesting Cladocera (Crustacea: Branchiopoda: Anomopoda: Chydoridae) from Deepor Beel, Assam, India

“…These include four globally interesting elements viz., the Australasian Disperalona caudata, the Asian Kurzia (Rostrokurzia) brevilabris and the Indo-Malayan Kurzia (Rostrokurzia) brevilabris is an interesting addition to the Indian Cladocera. Originally described from Thailand (Rajapaksa & Fernando 1986), this species is also known from Sri Lanka and Philippines. Our present report from northeastern India, therefore, merits biogeographic importance for extension of its range within the South Asian region.…”
