Family: Isotomidae Börner, 1913 — Subfamily: Isotominae Schaeffer, 1896
Family: Isotomidae Börner, 1913
Subfamily: Isotominae Schaeffer, 1896
Genus: Papillomurus Salmon, 1941
Papillomurus transequatoria n.sp.
Colour: In alcohol trunk bluish to purplish brown or grayish brown overlain with fine blue and rose coloured pigment granules. Head grey brown with a purple spot on the vertex, and two light bluish pigment bands extending towards the posterior margins of the ocellar fields to form a V mark with an intense purple base. Ocellar fields deep bluish black. Antennae pale ochreous with pale purplish pigment towards the apex of segments I, II and III. Ant. IV pale purplish brown. Legs and furcula pale ochreous without further pigment.
Clothing: Densely clothed with short simple setae sometimes faintly serrated towards their tips, and occasionally mostly around the posterior longer slender setae with a few serrations along their entire length. Setae of the antennae, legs and furcula, all moderately long and simple. Setae of the body, and of the basal segments of the legs, the antennae and the furcula, all arising from small papillae.
Body: Length, 1.47 mm. Antennae subequal to head in length, four segmented with the segments related as 53:33:30:17. Ant. IV with apical dome, stout stiff apical sense rod and numerous curved sense rods interspersed among the setae. Ant. III with many similar slender sense rods. Abds. III and IV related as 6:7. Ocelli eight to each side, six large subequal and two much smaller. PAO elliptical, equal to the diameter of an adjacent ocellus and with lateral lamellae as in Fig. 28. Rami of tenaculum each with four barbs, the corpus with a transverse basal row of three simple setae.
Legs: Claw with two strong exterior lateral teeth about half way down and one small inner tooth about two-thirds down. Base of claw finely granulate, unguiculus

about half as long as claw, lanceolate with three broad lamellae. Front feet with two slender clavate tenent hairs one slightly longer than the other. Middle feet and hind feet each with three slender clavate tenent hairs, the middle hair longer and stouter than the two lateral hairs, the longer middle hair not quite as long as the claw. A short basal seta to each side of claw.
Furcula: Mucro dens 3.2 times longer than manubrium. Dens annulated and corrugated, the uncorrugated part of the dens 2-3 times as long as mucro. Mucro indistinctly separated from dens, tridentate, with large apical, slightly longer preapical and large lateral teeth.
Locality: Described from one holotype specimen collected at Lachung, Sikkim, from moss on rotten tree trunk in pine wood at 8610′ altitude.
Genus: Rhodanella Salmon, 1945
Rhodanella plumosa n.sp.
Two specimens, one immature, in Dr. Clay's collection although not conforming entirely to the specifications of this genus do in my opinion come so very close to it that I have placed them in Rhodanella.
Colour: White overlain by pale bluish-violet granulate pigment in dorsal and lateral areas of metathorax and Abds. I-IV.
Clothing: Moderately clothed on the body with long and short very coarsely serrated setae, almost feather-like in some cases especially round the posterior (Fig. 34). Setae of the antennae, legs, furcula mostly simple or only very finely serrated. Those of the ventral surface of body and head shorter and finely serrated.
Body: Length: up to 0.6 mm. Antennae only slightly longer than head as 16:13; the four segments related as 14:20:26:44. Ant. IV with slender both curved and straight sense rods and setae. Apex of Ant. III with a pair of exposed stout curved sense rods each in its own cuticular pocket. Ocelli on black pigment patches, eight to each side, unequal; the anterior pair the largest, the outer posterior two the smallest. PAO small more or less egg-shaped and double outlined, about as long as half the. diameter of the adjacent ocellus. Abds. III and IV subequal in length; Abds. V and VI fused; tenaculum not seen.
Legs: Claw as in Fig. 31 with a pair of small external lateral sub-basal teeth, two strong inner teeth and a short basal seta to each side. Unguiculus granulated, lanceolate, with broad semiciricular inner lamella and broad straight outer lamella. A single long slender non-clavate tenent hair to each foot almost as long as claw.
Furcula: Reaching forward to Abd. II. The manubrium related to the mucrodens as 30:95. Mucro indistinctly separated from dens, small, related to the dens as 91:4, and with three prominent teeth as in Figs. 32-33. Dens annulated and corrugated, the uncorrugated portion about 2.5 times as long as mucro.
Localities: Lachung, Sikkim, 8610′ altitude in moss on pine trunks in pine woods; Imphal, Manipor State in rotting Eichornig.
