Etymology.

This name is derived from the Latin word ‘undatus’, which means ‘wavy’, referring to the shape of the proximal edge of the paracymbium; adjective.

Diagnosis.

This species is related to Tapinopa vara Locket, 1982 (from Malaysia), but differs in the shape and size of terminal apophysis ( Locket 1982: figs 100-102); the pit hook in Tapinopa undata sp. n. is longer and has a more pointed tip compared to the related species (Fig. 93C).
