Diagnosis.

Males of this species can be easily distinguished from those of the congeneric members by the single, massive distal process of the paracymbium (see Grall and Jäger 2016: fig. 7). Females are distinguished by the reduced scape (Sp) (Fig. 62D), the copulatory ducts (Cd) shaped like brackets and the very long, spiral fertilization ducts (Fd) with at least five coils (Fig. 62 E–F). Nesticella yui is closely related to Nesticella gongshanensis sp. n. (see Fig. 52 A–F) from which it can be separated by the wider scape (Sp), the larger distance between the copulatory openings (Co) and the generally different shape of the copulatory ducts (Cd) (Fig. 62 D–F vs. Fig. 52 D–F).
