Tylencholaimus micronanus Yeates, 1979: 423–425.
Tylencholaimus vanguimus Mohilal & Dhanachand, 2000: 33–35.

Material examinedINDIA – Kerala State • 6 ♀♀; Kasaragod district, Ranipuram National Park; 12.4º26′18.3″ N, 75.3º58′94.4″ E; 5–15 cm depth; 15 Nov. 2016; soil samples collected from around the roots of grasses (unidentified); slides reference number AMU/ZD/NC/ Tylencholaimus micronanus /1–3. – Karnataka State • 4 ♀♀; Kodagu district, Bhagamandala; 12°23′29.1″ N, 75°31′50.0″ E; 5–15 cm depth; 8 Nov. 2016; soil samples collected from around the roots of grasses (unidentified); slides reference number AMU/ZD/NC/ Tylencholaimus micronanus /4–6.
RemarksYeates (1979) described Tylencholaimus micronanus from New Zealand. Baqri (1991) reported it from Sikkim, India whereas, Peña-Santiago & Coomans (1994c) restudied the type material of this species and provided a complete description. Mohilal & Dhanachand (2000) described a new species, Tylencholaimus vanguimus from Manipur, India which was synonymized with T. micronanus by Peña- Santiago (2008). The morphometrics of the present populations conform well with the type population except in having a slightly shorter odontostyle (4.5–5.5 vs 6.0–7.0 μm) and in the presence of a terminal caudal pore (vs absent). The present population also conforms well with Sikkim as well as Manipur populations except in having a shorter and robust body (0.31–0.39 vs 0.44 mm, a = 17–23 vs 25); lower b value (2.4–2.8 vs 3.6); a slightly shorter odontostyle (4.5–5.5 vs 6.0 µm) and tail (11–12 vs 13 µm) than in the Sikkim population; and a slightly lower c’ ratio (0.8–1.0 vs 1.0–1.1) than in Manipur population, as well as the presence of terminal caudal pore (vs absent in the Manipur population).
