Morphology
Soldier
Head and antennae yellow, nasus brown, the upturned part of the pronotum brownish yellow, thorax, abdomen and legs pale white. Most individuals have almost no hairs on the head and pronotum; a few occasionally bear two to four hairs. Large form: head pear-shaped, narrow in front and broad behind, the lateral margins bulging, the posterior margin slightly concave in the middle; nasus thick and short, not upturned in profile, its tip slightly lower than the posterior margin of the head; mandibles bluntly convex and without a pointed spine. Antennae with 13 segments, the third longer than the second, the second longer than or equal to the fourth, the fourth shortest. Pronotum saddle-shaped, the anterior margin slightly concave, the posterior margin without a concavity. Small form: colour like that of the large form but slightly paler, hairs on the head and on the dorsum of thorax and abdomen fewer; head pear-shaped, narrow in front, widest near the back of the head, the posterior margin slightly concave; mandibles bluntly convex without a pointed spine; antennae with 12 to 13 segments, the third longer than the second or nearly equal; anterior margin of the pronotum with a small notch in the middle, the posterior margin not concave.
Alate
Worker
In the worker the apical tooth of the left mandible equals the first marginal tooth, the cutting edge between the two marginal teeth wavy and very inconspicuous.
Nymph
Abstract (from the source)

The large soldier has a pear-shaped head, narrow in front, with a short thick nasus not upturned in profile and blunt convex mandibles lacking spines. The small form is paler with a narrow front and twelve or thirteen antennal segments, the pronotum notched at the middle of its front margin.

A. sinuosus (Tsai et Chen 1963) Fujian,Guangdong, Sichuan, Yunnan. 3. A. pyricephalus Akhtar 1975. Hunan (Yizhang Xian) 4. A. smensis, sp. nov. The last one,is collected from Tibet-Survey corps of Academia Sinica duringautumn 1974 and considered new to science. Ahmaditermes sinensis, sp. nov. Major soldier (figs. 1--3) Body longth 4.15mm. Head yellow, lighter posteriory, nasus reddish brown.Head without nasus pear shaped or more like the violintrunk, head width larger thanlong, broadest in middle, lateral. sides sliglhtly emarginated below antennal carinae,and strongly, bulging in posterior half, posterior margin emarginated prominently inmiddle, vertex with some long bristles, nasus slightly upturned, tip. milky white,translucently, scattered with small hairs, Fontanelle tube prominent, extending tobefore middle of head. Antennae with 12 articles, sometimes 13. lst longest, cylin-drical. 3rd shortest and narrow. cylindrical, article 34 in the case of 12. whilewith 13 articles 34, 5--11 broader, moniliform, last one slender, ovoid, and ligh-ter, lst.hairless, 2--3 lesser hairy, 4--12 more hairy.

Abstract
- First record of Ahmaditermes emersoni Maiti (Isoptera, Termitidae, Nasutitermitinae) from Meghalaya, India
Abstract
The nasutiform termite species Ahmaditermes emersoni Maiti is reported from Meghalaya, India for the first time. All the studied samples of the species were collected from betel nut plantation in Mawlynnong area of East Khasi Hill district of the state. Morphology of both the soldier and worker castes of the species was studied in detail and the identification was done based on their morphological characteristics. Redescription of morphology and revision of morphometric of both the soldier and worker castes are provided in this article. With the record of this species, the genus Ahmaditermes is also reported for the first time from the state.
