Material

IRAN: Mazandaran Province: 1♂ ( ZMMU), Nashtarud , 36.733333°N, 51.066667°E, 9‒10 June 2000 (Y.M. Marusik); 2♀ ( ZMMU), Ramsar, 36.916667°N, 50.666667°E, 10 June 2000 (Y.M. Marusik) .

Comments

This species differs from the congeners occurring in the region by the dark lateral patches on clypeus, three pairs of sublateral dots on carapace (indistinct in some specimens), and the presence of dots on legs (but not annulations). We noted that it has a kind of retrolateral tibial apophysis (arrowed in Figure 4A ), which has not been previously documented.

Distribution

West Palaearctic. Introduced in South Africa, China, Korea, Japan, New Zealand, Canada, USA, South America ( WSC 2023). New record for Iran ( Figure 9 ).
