Geographic Range [top]
Range Description: The range of A. hisopa as currently recognised is large, extending from India (e.g. Fraser 1933, Prasad and Varshney 1995), Nepal (Vick 1989), Myanmar (Fraser 1933) to Thailand (Fraser 1927, Hämäläinen and Pinratana 1999), Viet Nam (Asahina 1969, 1997) and southwards to Peninsular Malaysia (e.g. Fraser 1933, 1942; Kalkman 2004; Orr 2005), Java (Lieftinck 1929, 1934 etc., as A. aciculare) and Sumatra (Lieftinck 1935 etc., as A. aciculare). However records are relatively scarce and it may exist in scattered, isolated populations. Moreover it is not clear if all records refer to the same species (see Taxonomic Notes).

Population [top]
Population: Judging by published records, A. hisopa seems to be quite scarce and local in occurrence over much of its range. However Orr (2005) states that it is “common around ponds and drains in open disturbed areas” in Peninsular Malaysia.
Current Population Trend: Unknown
Additional data:
? Population severely fragmented: No
Habitat and Ecology [top]
Habitat and Ecology: Appears to prefer shallow, weedy standing water habitats, often in open and disturbed areas.
Systems: Freshwater
Threats [top]
Major Threat(s): Habitat loss from human development.
Conservation Actions [top]
Conservation Actions: Further distributional data, and taxonomic work, is needed to make a truly accurate conservation assessment.
