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 View Fig View Fig ). This new species resembles M. yinae sp. nov. ( Figs 13–15 View Fig View Fig View Fig ), 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 View Fig , 6B View Fig , 13D View Fig , 15B View Fig ). In prolateral view, terminal portion of embolus arc-shaped, slightly covered by conductor in M. longlingensis ( Figs 5A View Fig , 6A View Fig ), erect and passing through conductor in M. yinae sp. nov. ( Figs 13A View Fig , 15A View Fig ). In retrolateral view, metaine embolic apophysis wider anteriorly in M. longlingensis ( Figs 5D View Fig , 6B View Fig ), wider medially in M. yinae sp. nov. ( Figs 13D View Fig , 15B View Fig ).
