Kingdom Phylum Class Order Family
Animalia Arthropoda Insecta Odonata Coenagrionidae

Scientific Name: Aciagrion fasciculare Lieftinck, 1934
Taxonomic Notes: A poorly known species; the only published records are from a small area of west Java. G.T. Reels and this assessor (R. Dow) found what appears to be this species at Bako National Park in west Sarawak, Malaysia in 2005 (R. Dow pers. obs. 2008). Confirmation of the identity of material from Bako awaits detailed comparison against the type series, but agreement with the original description is good, except in size and for minor details of colouration; such differences might be expected given the distance between the populations.

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2009
Date Assessed: 2007-03-01
Assessor(s): Dow, R.A.
Reviewer(s): Kalkman, V. & Clausnitzer, V. (Odonata Red List Authority)
The known locations for this species are a small area of west Java and kerangas (tropical moist forest) shrubland in Bako National Park in Sarawak. There appear to be no records from Java after 1954, although, at least in part, this reflects a lack of expert sampling on the island. The area where the species is found at Bako is small, and vulnerable to fire in dry spells; the habitat here is unusual in Sarawak and possibly unique within the state. The total number of locations from which the species has ever been recorded is less than five, and the identity of the Sarawak population has not been completely confirmed yet. It meets criteria B1a and B2a for Endangered status, and, taking a precautionary attitude, it can be inferred to meet B1b(iii) and B2b(iii); for these reasons it is assessed as Endangered. If the Sarawak population is eventually determined to be of another species, then, in the absence of expert sampling in Java, it would have to be reassessed as Data Deficient.

Geographic Range [top]

Range Description:Known from two disjointed areas: West Java (Lieftinck 1934, 1954) and Bako National Park, Sarawak (Dow 2005). In West Java the recorded locations are lake Njalindung and a few sites near Sukanegara, about 20 km to the east of lake Njalindung.

Population [top]

Population:There is no current information available on the west Javan populations. Writing in 1934 Lieftinck described the species as "excessively abundant" at Lake Njalindung and as common at the other sites. The form at Bako in Sarawak was common on visits in March and May of 2005.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:Appears to prefer shallow, well vegetated marshes, shallow lake margins (Lieftinck 1954) and, in the case of the Sarawak population, small, shallow, open streams in kerangas (tropical heath) shrubland. The kerangas shrubland at Bako National Park is a scarce, possibly unique, habitat in Sarawak.

Threats [top]

Major Threat(s): Habitat loss due to development or fire. The status of the habitats in Java is unknown, but doubtful. The known population in Sarawak is within a national park, but the habitat is very vulnerable to fire, and the area in which the species occurs is relatively small. The habitat in Sarawak is unusual, and possibly unique within the state.

Conservation Actions [top]

Conservation Actions: The status of this species in Java needs to be checked (existing data is from the 1930s). Further data on distribution is urgently needed to plan conservation measures. The species needs to be searched for in Java, Borneo and east Sumatra.
