Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2006
Date Assessed: 2006-01-31
Assessor(s): Clausnitzer, V.
Reviewer(s): Clausnitzer, V., Dijkstra, K.-D.B. & Suhling, F. (Odonata Red List Authority)
Justification:
Ephiophlebia laidlawi has been found from various localities in the eastern Himalayas during the last years. Thus the species seems to be less endangered and restricted than previously thought. Silsby gives a comprehensive overview on the recent records (Silsby, 2001, p. 126), which are Chittrey, Mt Shivapuri, Kathmandu area, Solokhumbu region, all in Nepal. From the present state of knowledge E. laidlawi no longer qualifies for the Vulnerable (VU) criteria, but nearly meets the thresholds for VU under criterion B1ab(iii) due to the restricted range of the species and a degradation and pollution of water courses even in higher elevations.

Due to its restricted range, still insufficient knowledge on its distribution and population sizes and its importance as a relict species, it remains as Near Threatened on the global Red List. But it has to be noted, that an attempt, to check the site above Kathmandu in Nepal for specimen recently failed and could not be repeated for insecurity (H. Dumont, pers comm.). More studies are needed concerning its present range and potential threats.
