INSECTA : ISOPTERA

The eastern region of the Indian subcontinent is very rich and diverse faunistically. The termites of this part have been studied somewhat extensively (Roonwal and Chhotani, 1962; Chhotan.i, 1975, 1976 ; Chhotani and Das, 1983 ; Mathur aI?-d Thapa, 1965; Sen-Sarma and Thakur, 1979 ; an4 Lahiri and Ghosh, 1980) and as many as 49 species have been reported from the eastern states of the Indian Union. In the present paper, thirteen species belonging to eleven genera under three families are reported and one of these is new to science.


INTRODUCTION
The eastern region of the Indian subcontinent is very rich and diverse faunistically. The termites of this part have been studied somewhat extensively (Roonwal and Chhotani, 1962;Chhotan.i, 1975Chhotan.i, , 1976 ; Chhotani and Das, 1983 ;Mathur aI?-d Thapa, 1965;Sen-Sarma and Thakur, 1979 ; an4 Lahiri and Ghosh, 1980) and as many as 49 species have been reported from the eastern states of the Indian Union.
In the present paper, thirteen species belonging to eleven genera under three families are reported and one of these is new to science.
Material examined: One imago, Miao, 5.v.1981. Remarks: The single imago cannot be referred to any known imagos of the Neotermes species. Due to non-availability of associated soldiers it is not identified up to species level.
2. Glyptotermes tikaderi sp. n.    close to each other, latter with a long posterior margin; 3rd with a 19 n 9, curved posterior margin ; 4th short. Right mandible with two marginal teeth in middle. Postmentum long, club-shaped; anterior broader portion with faint grooves and a few bristles, sometimes faintly bilobed ; waist long and narrow, width at waist less than half to about half of maximum width. Pronotum flat, much wider than long and almost as wide as head; anterior margin deeply incurved; posterior margin faintly incurved. Meso-and metanota narrower than pronotum ; latter only slightly wider than former. Legs short and stout; apical tibial spurs 3: 3 : 3 ; tarsi 4-jomted. Abdomen elongate; cerci 2-jointed ; styli single-jointed, finger-like. Head creamish white ; mandibles creamish witp. dark brown toothed margins ; pro-mesoand metanota pale yellowish brown; abdomen creamish, paler than head. Head and body sparsely hairy_ Total body-length c 7.0 .. 9.5 rnm.
Head subcircular, slightly wider than its length to base of mandibles. Antennae 14 to 15 segmented; segments 3-6 or 7 short, ring-like; 8 onwards broadly pyriform. Eye-spots translucent or faintly greyish, round. Labrum broad, dome-like. Mandibles typically Glyptotermestype. Pronotum semi-lunar; anterior margin deeply incurved ; slightly narrower to slightly wider than head. Legs and abdomen as in soldier.  14.iv.1981, from wood; deposited in National Zoological collections, Zoological Survey of India, Calcutta. One paratype soldier and two paramorphotype pseudoworkers, with the same data, each deposited in Entomological collections, Forest Reseal'ch Institute, Dehra Dun (Uttar Pradesh, India) and in American Muse_urn of Natural History, New York ( U. S. A, ).
Distribution: It is a very widely distributed species on the Indian subcontinent.

A{acrotennes khajuriai
Material examined: Soldiers (major and mino~ ) and workers, Near Zero Camp, 3 km N. of Deban, 8.iv.1982 (two vials, one with a soldier major mixed with Odontotermes feae and the other with soldier minor and workers ).
Distribution: This species has earlier been recorded from Meghalaya in India and from Bhutan. Distribution: It is a widely distributed species and is known from lp.dia, BangIa Desh, Bhutan, Burma, Thailand and Vietnam.
