Etymology:
The specific name is derived from the Latin
unda
, meaning “wave”, referring to the wavy shape of the male embolic apophysis; adjective.
Diagnosis:
Males of
Sinopoda undata
sp. nov.
can be distinguished from those of other
Sinopoda
species by 1. uniquely wavy and well developed embolic apophysis, and 2. long and flagelliform embolus (
Figs 8A– E
); females may be recognised by 1. distinct and long anterior rim connecting the two lobal epigynal pockets, and 2. uniquely slender and distinctly bent internal duct system (
Figs 8G–H
).
