"Biology. According to Simon (1876) this species is found in marshy areas but Tongiorgi (1968) records it from pine woods on dry, sandy soils with a well developed herbaceous ground layer." Russell-Smith, 1982

Diagnostic description: 

"Diagnosis. The male can be distinguished from all other species by the barbed tegular apophysis. The female is closest to T. rubriceps but is considerably larger and has a more clearly defined epigynal plate." Russell-Smith, 1982


"Distribution. The Mediterranean cost of Europe from Spain to Yugoslavia." Russell-Smith, 1982
