Summary

Tripylella jianjuni sp. n. (Tripylidae) is described from New Zealand. Females are characterised by a relatively long body (1743 (1675-1860) μm in the female and 1747 (1576-1979) μm in the male), outer labial setae (8-9 μm long) and cephalic setae (4-5 μm long) in a single circle, two large subventral teeth in two adjacent stomatal chambers, relatively short pharynx (b = 5.5 (5.4-5.6) in the female and 5.7 (5.3-6.1) in the male), vulva located slightly anterior to mid-body (V = 44 (43-46)), protuberant lips, and long filiform tail (461 (398-531) μm, c = 3.8 (3.3-4.2) and c′ = 23.2 (18-29) in the female, and 450 (362-511) μm, c = 3.9 (3.6-4.4) and c′ = 19.0 (16.0-20.8) in the male), tail with three ventromedian caudal setae. Males have arcuate spicules 37 (35-41) μm long, gubernaculum straight, 14 (12-16) μm long, three ventromedian supplementary papillae located anterior to the cloacal aperture, and a single plus four pairs of subventral caudal setae located posterior to the cloacal aperture on the tail. Preliminary analyses of phylogenetic relationships within the Triplonchida were done using the SSU and D2-D3 region of LSU DNA sequences.
