Abstract

The present report describes morphometric variations of 52 species of the Genus Odontotermes from Bangladesh Burma China India Indonesia Malaysia Pakistan Philippine Sri Lanka Singapore and Thailand. In the Odontotermes different groups of species can be recognized i.e. group of species having postmentum distinctly longer than wide groups of species having potmentum extraordinarily wide and arched antennae uniformly coloured antennae darker distally etc. In group of species having postmentum extra ordinarily wide and arched (only slightly longer than wide) and antennae uniformly coloured more variability was recorded for length of pronotum in case of O. adampurensis Akhtar (C.V 9.35) for tooth of left mandible from tip in case of O. escherichi (Holmgren) (C.V. 10.3) and in case of O. proformosanus Ahmad (C.V. 10.5) whereas minimum variability was recorded for length of postmentum in O. sarawakensis Holmgren (C.V. 1.60). In group of species having postmentum extraordinarily wide and arched but having distal articles of antennae darker than proximal ones more variability was recorded for tooth of left mandible from tip in O. latiguloides Roonwal et Verma (C.V. 13.9) and in case of O. microdentatus Roonwal et Sen Sarma (C.V. 8.60) for length of postmentum in O. guptai Roonwal & Bose (C.V. 11.8) and for width of head at sidebase of mandibles in O. giriensis Roonwal et Chhotani (C.V. 7.72). In group of species having postmentum not extraordinarily wide and arched distinctly longer than wide antennae darker distally and tooth of left mandible placed at base of apical third more variability was recorded for tooth of left mandible from tip in O. assamensis Holmgren (C.V. 9.72) O choaensis n.sp. (C.V. 18.0) O. obesus (Rambur) (C.V. 13.10). Minimum variability was recorded for length of left mandible in O. gurdaspurensis Holmgren and Holmgren (C.V. 4.43). In the group of species having uniformly coloured antennae more variability was recorded for length of pronotum in O. assmuthi Holmgren (C.V. 11.1) O. brunneus (Hagen) (C.V. 7.55) for width of postmentum in O. koechongensis n.sp. (C.V 7.54) for tooth of left mandible from tip in O. malabaricus Holmgren (C.V. 26.4). However minimum variability was noticed for tooth of left mandible from tip in case of O. oblongatus Holmgren (C.V. 3.04) maximum width of head in O. paradenticulatus Ahmad (C.V. 1.26) and width of pronotum (C.V. 1.89) in O. formosanus (Shiraki) which were less variable characters. In group of species having postmentum not extraordinarily wide and arched distinctly longer than wide and tooth of left mandible in basal third but with uniformly coloured antennae more variability was recorded for length of pronotum in O. bogoriensis Kemner (C.V. 8.31) O. parvidens Holmgren et Holmgren (C.V. 8.33) for width of postmentum in O. ceylonicus (Wasmann) (C.V. 10.0) and O. distans Holmgren et Holmgren (C.V. 8.89) for tooth of left mandible from tip in O. feae (Wasmann) (C.V. 12.30) O. karnyi Kemmer (C.V. 10.1) O. javanicus (C.V. 11.10) O. sundaicus Kemmer (C.V. 9.46) for width of head at sidebase of mandibles in O. horai Roonwal et Chhotani (C.V. 15.6) for length of postmentum in O. maliki Akhtar (C.V. 6.00). Minimum variability was recorded for length of left mandible in O. grandicep (C.V. 3.73) O. horni (C.V. 4.13) O. longignathus Holmgren (C.V. 3.78) for length of postmentum in O. holmgreni Snyder and Emerson (C.V. 1.62) O. maesodensis Ahmad (C.V. 1.51). In group of species having postmentum moderately arched antennae uniformly coloured and tooth of left mandible placed at base of apical third more variability was recorded for tooth of left mandible from tip in O. kepongensis n.sp. (C.V. 10.6) for length of head to sidebase of mandibles in O. kistneri n.sp. (C.V. 16.67). Whereas minimum variability was recorded for length of postmentum in O. singaporensis n.sp. (C.V. 1.73) and in case of O. takensis Ahmad (C.V. 3.85). The morphometric variations presented in this report will provide a standard of comparison for specimen from different localities of the range of distribution of that species and other species of the genus Odontotermes. Some samples on the basis of variability have been described as new species but were previously listed under known species. The new species of the genus described here are: 1. Odontotermes choaensis n.sp. 2. Odontotermes kepongensis n.sp. 3. Odontotermes kistneri n.sp. 4. Odontotermes singaporensis n.sp
