Ephemeroptera Larvae in Singapore: a Taxonomical Approach
نویسندگان
چکیده
Pollution-sensitive mayflies have been used extensively in water quality monitoring studies. In order to realise more of their ecological importance, it is important to be able to describe and understand the ecology of that taxa. Ephemeroptera in Singapore have not been extensively described so far. This study aimed to establish the baseline for identifying local ephemeropteran taxa in lentic habitats and a key was generated based on specimens from Lower Peirce reservoir. A total of 3 families, 4 genera and 1 subgenus were recorded. An alternative taxonomical approach was tested, using DNA barcoding methods. This provided ample evidence to distinguish between specimens but more work is needed to verify species-wise distinction. Methods were devised to rear live nymphs for larval-adult matching. These methods include transportation of live nymphs and the designing of a rearing chamber which managed to sustain 10 nymphs for periods ranging from 1 to 8 days. This study is a significant step in establishing preliminary information on ephemeropteran taxa in Singapore.

First report of Simuliidae and Chironomidae (Diptera) living on nymphs of Lachlania Hagen (Ephemeroptera: Oligoneuriidae) in South America
We report cases of Simuliidae and Chironomidae living on Lachlania nymphs (Ephemeroptera). This is the first record of these associations in South America. Simulium exiguum (pupae and larvae), Simulium cuasiexiguum (larvae), Cricotopus sp. (larva) and Rheotanytarsus sp. (larva) were found associated with Lachlania nymphs. We believe that all of these associations can be classified as opportunis...

Fungal symbionts (Harpellales) in Norwegian aquatic insect larvae.
Collections of aquatic insect larvae in Norway, over a 40 d period in May and Aug 2002, resulted in finding more than 25 species and one new genus of Harpellales (Trichomycetes). Nine new fungal symbionts are described and named: Ephemerellomyces aquilonius (a new monotypic genus), Glotzia stenospora and Legeriosimilis europaeus in mayfly nymphs (Ephemeroptera); Genistelloides amplispora and G....

A new species of primitive tuskless burrowing mayflies (Ephemeroptera: Palpotarsa: Behningiidae), Behningia baei, new species, is described from larvae taken in Thailand. The new species is differentiated from congeners primarily by its labial palps, labrum, and base of the mid legs. It is the first species of the genus Behningia, and only the second species of the family Behningiidae, to be ta...

Here, we describe Cinygmula tetramera, sp. nov. (Ephemeroptera: Heptageniidae), which has male imaginal forceps with three distal segments, based on male & female imagos reared from larvae. The structure of the penes of this species is similar to that of Cinygmula irina Tshernova & Belov, 1982, a description and drawing of which are also presented in this paper. The larvae of C. irina are descr...
