( NHWM): Chhindwara Distr., Bhadhua Chora (stream), ca. 10 km E Matkuli near Mahul Jhir, 400 m, 28.ii.2008, lgt. M. Jäch, S. & P.Sharma; 1♀ ( NHMW): Hoshangabad Distr., Dhobighat Nala (stream), ca. 2 km SE Pachmarhi,Saphura Range, 900 m, 27.ii.2008, lgt. M. Jäch, S. & P. Sharma.
Redescription. Body length 1.5–1.7 mm (holotype 1.5 mm), maximum body width 0.9–1.0 mm (holotype 0.9 mm). Head and labrum black and pronotum uniformly yellowish; elytra yellowish with slightly darker lateral parts; legs reddish to yellowish. Head with strong microsculpture on interstices; punctation sparse, each puncture bearing pointed seta. Eyes separated by 3.5× the width of one eye in dorsal view. Pronotum with sparse setiferous punctation similar to that on head; interstices without microsculpture. Elytra with 10 striae sharply impressed except anteromedially (near scutellar shield) where neither striae nor serial punctures are visible; intervals weakly convex at midlength and near apex; interval punctation sparse, setiferous; interstices without microsculpture. Aedeagus ( Figs 6 View Fig K–O) 0.4 mm long. Phallobase not much wider at base of parameres than more basally, only indistinctly narrowed at midlength; arcuate in lateral view. Paremere moderately wide basally, slightly narrowing towards apex, apex widely angulate. Median lobe widely bottle-shaped, rounded apically, without paired subapical projections; apex not reaching level of parameral apices; gonopore rounded, situated far from apex.
Differential diagnosis. Thysanarthria ceylonensis resembles T. bengalensis , T. brincki and H. saurahana in having strong mesh-like microsculpture on the head, but it can be easily distinguished from all these species as well as from all other Thysanarthria by a very characteristic aedeagus.
Biology. Specimens from Madhya Pradesh were collected at the sides of small to large rivers with stony banks (e.g., Fig. 11D View Fig ) but precise microhabitat is not known (M. A. Jäch, pers. comm.).
Distribution. Described from Sri Lanka ( HEBAUER 2001) but here recorded from central India (Madhya Pradesh), hence the species is likely widespread in the Indian Peninsula.
