Anax Leach is a large dragonfly genus
distributed throughout the world (Tsuda 2000). Currently 29 species are recognized (Schorr & Paulson 2012). The adults of different species are found
in diverse wetland habitats such as ponds, marshes, lakes, rivers and
streams. In India, hitherto six
species of Anax have been recorded
(Subramanian 2009). Here, we report
a new record and range extension of Anax panybeus Hagen, 1867 to Andaman and Nicobar Islands.
Materials
examined: 4868/H13, 1 male, 01.viii.1984, 27km on NS Road, Swarup Nullah, Great Nicobar Island; 4869/H13, 1 male,
01.viii.1984, 35km on NS Road, Shashtri Nagar, Great
Nicobar Island, coll. S.S. Saha. The Specimens were
deposited in National Zoological Collection, Zoological Survey of India, Kolkata.
Measurements: Abdomen: 64mm (including anal
appendage); anal appendage: 7mm; hindwing: 51mm.
Description: Labium and labrum brownish-yellow. Labrum narrowly bordered with
brown. Front yellow with a distinct
black ‘T’ shaped marking on the upper surface. Prothoraxreddish-brown. Thorax
pale green. Legs black. Wings hyaline but a large patch of amber yellow on hindwingspreading between posterior end of discoidal cells
and slightly distal to node. Pterostigma darkish brown covering more than 2½
cells, long and narrow; discoidal of fore wing
6-celled and basal cell divided into two cells, 4-celled in hindwing;
five cubital nervure in forewings and four in hindwing. Hypertrigone traversed three times in all the wings. Membrane brownish with
a patch of white at extreme base. Nodal Index: 9-18/18-9 in forewings 9-12/12-10 in hindwings. Two robust antenodal nervure present in the forewings. Anal loop with 10–12 cells. Abdomen: 1st segment
pale green; 2nd segment pale green on lower parts and bluish on
dorsum and subdorsum; 3rd to 10thsegments dark reddish-brown with black markings. Abdominal segment
3 is more constricted and distinctly elongated (about 11–12 mm). Anal appendages are reddish-brown;
superior appendages are thick and strong (Images 1–4).
Discussion: The specimens in National Zoological
Collection, ZSI were compared with description and illustrations (Lieftinck 1942) and identified. The species is known
to be distributed widely in Brunei Darussalam, Cambodia, Indonesia,
Japan, Lao People’s Democratic Republic, Malaysia, Myanmar, Philippines,
Singapore, Taiwan, Thailand and Timor-Leste (Karube2009). The changes in coloration of
the abdomen from greenish-yellow with black markings in live specimens to
reddish-brown with black markings in the ZSI specimens could be a result of
preservation. The current range
extension of Anax panybeuson Great Nicobar Island is due to the proximity of the Nicobar group of islands
to Sumatra of Indonesia, all part of the Sundabiodiversity hotspot. Recent
studies that documented new odonate species from
Andaman and Nicobar Islands (Hämäläinen et al. 1999; Yeh & Veenakumari 2000; Hämäläinen 2002) also emphasisethat more detailed and extensive surveys are required to comprehensively
document the odonate fauna of the islands.
