Description: Body length up to 1.36 mm . Colour pattern: Main colour blue, marked with green and yellow spot on the thorax and large abdomen. Head dark blue, ocelli dark, lighter form in between two ocelli, Ant. I-IV with blue pigment, base of Ant. I pale, all legs are light blue and furcula blue. Thorax and large abdomen deep blue dorsally with green and yellow marking, a big yellow spot present dorsally on large abdomen ( Figure 1 ). Head: Length of antennae: head diagonal = 1:5. Head clothed with short, smooth, plain setae. All setae are uniform in size ( Figure 2 ). Mouth parts shown as in Figure 3 . Antennae: Length ratio of antennal segments I: II : III : IV as 1: 1.7: 2.6:5.1. Ant. I with 3 smooth setae medially ( Figure 4 ). Ant. II with 9-12 setae. Ant. III with two sensillum(s) basally and one micro-sensillum(ms) ( Figure 5 ). Ant. IV with 7 sub segments ( Figure 6 ). Clothing: Head, Antennae, legs, thorax and abdomen clothed with plain, short, smooth setae. Legs: Unguis with two inner teeth anterior and medially and one outer tooth medially ( Figure 7 ). Unguiculus very thin without teeth ( Figure 8 ). 3 long clavate tenent hair on each foot as long as unguis ( Figure 9 ). Tita II row p: 3 setae ( Figure 10 ). Length of longest setae of Tita III > diameter of Tita ( Figure 11 ). Furcula and genital plate: Tenaculum with 3 barbs each and without setae ( Figure 12 ). Length ratio of mucro: dens: manubrium as 1: 2.9:1.5. Number of manubrium anterior setae is 5 ( Figure 13 ). Formula of anterior setae of dens 2,1,1,1...1( Figure 14 ). Mucro with very narrow anterior furrow, basal 2/3 with furrow, mucro with light serration ventrally ( Figure 15 ). Abd. VI dorsally with Table 5.

Appendices anales (App. an.) narrow, spatulate shape, out edge pointed, without serration ( Figure 17 ). Ratio of App. An: mucro = 1:2. Etymology: The new species is named after the type locality. Biology: In Meghalaya , found on the Umiew river bed of East khasi Hill district . Discussion : The new species from East khasi Hill district of Meghalaya , India can easily distinguished from other known species of Bourletiella by colour pattern, claw structure, Tita II row p:3 setae, and Annal appendages. It is close to Bourletiella hortensis ( Fitch, 1863 ) , in having similar type Tita II row p:3 and Ant. IV with 7 sub segments but strongly differ from Bourletiella hortensis in the characteristics given below in the Table 5 . Summary A total of 3 species of Collembola belonging to 3 genera under 3 families Entomobryidae , Isotomidae and Bourletiellidae have been described as new to science from India . The detailed descriptions of each species of Collembola with discussion for difference between closely related species, total numbers of species in the world as well as from India , key to the Indian species and their distribution are also provided.
