Tetrabothrus rougemonti PACE, 1998

Tetrabothrus rougemonti PACE, 1998: 961 ff.

Type material examined: Holotype ♂: “ Hong Kong, Tai Po V.1996, G . de Rougemont / Holotypus Tetrabothrus rougemonti m., det. R. Pace 1996 / Tetrabothrus rougemonti sp. n., det. R. Pace 1996” ( MHNG).

Comment: The original description of T. rougemont i is based on a male holotype and a female paratype from Hong Kong ( PACE 1998). The holotype was examined in order to investigate the status of T. inflexus , whose aedeagus is similar to that of T. rougemonti . The comparison revealed no differences in coloration or other external characters. The aedeagi of all the males of T. inflexus examined thus far, however, are constantly distinguished from that of the holotype of T. rougemonti by a more strongly bent, apically longer (lateral view), and more slender (ventral view) ventral process ( Figs 440–441 ). Nevertheless, the possibility that specimens with an aedeagus of intermediate conditions may be found and that the observed differences may eventually have to be interpreted as intraspecific variation cannot be ruled out with certainty.
