Differential diagnosis
Meta longlingensis sp. nov. can be distinguished from the other Chinese Meta species by the hookshaped tip of the cymbial ectobasal process of the male palp (Figs 5–6). This new species resembles M. yinae sp. nov. (Figs 13–15), but can be distinguished from the latter by the following chararacters. Cymbial ectobasal process without the spine-like apophysis in ventral view found in that of M. yinae sp. nov. (Figs 5D, 6B, 13D, 15B). In prolateral view, terminal portion of embolus arc-shaped, slightly covered by conductor in M. longlingensis (Figs 5A, 6A), erect and passing through conductor in M. yinae sp. nov. (Figs 13A, 15A). In retrolateral view, metaine embolic apophysis wider anteriorly in M. longlingensis (Figs 5D, 6B), wider medially in M. yinae sp. nov. (Figs 13D, 15B).
Etymology
