Microsensillar formula as 11 / 11100. Thorax without ventral chaetae. Abd. VI with 10 erect horizontal chaetae at tip. Claw without inner and lateral teeth. Empodial appendage about half as long as unguis, rather thin. Ti. 1 – 3 with 21, 21, 22 chaetae respectively, without clavate tenent hairs. Two inner chaetae on Ti. 3 much thinner than others (Fig. 1 D). VT with 4 + 4 laterodistal and 4 posterior chaetae, no anterior chaetae. Tenaculum with 3 + 3 teeth and 1 chaeta. Anterior furcal subcoxa with 4 (3 or 5) chaetae, posterior subcoxa with 3 (2 or 4) chaetae. Manubrium without anterior chaetae, posterior with 3 + 3 laterobasal, 2 + 2 in distal transversal row, and 4 + (3) 4 in central part. Dens with 1 anterior and 3 posterior chaetae (Fig. 1 C). Mucro massive, bidentate. Ratio of manubrium: dens: mucro = 6.6: 2.5: 1. Female genital plate as in Fig. 1 C.	en	Huang, Cheng-Wang (2025): Two new species of the genus Narynia (Collembola, Isotomidae) from China. ZooKeys 1240: 65-72, DOI: 10.3897/zookeys.1240.141871
