description: Nyssus jaredwardeni sp. nov.
(Figs 16c, 75a–e, 76a, b. Map 38)
Material. Queensland: holotype ♂, Ipswich, Redbank Plains, 27°39'S, 152°51'E, eucalypt woodland, 7 Apr 2001, J. Warden, QM S55392. Paratype: Queensland: 1♀ (allotype), Middle Ridge, Toowoomba, 27°36'S, 151°57'E, 27 Apr 1998, J. Warden, in bark on tree in park, QM S42063.
Diagnosis. Males differ from those of N. semifuscus sp. nov. in that, viewed ventrally, the embolus base is a straight diagonal ridge (Fig. 75e); females differ from those of N. insularis (L. Koch, 1873) in that the head of the spermathecae is relatively smaller with a curved spermathecal stalk (Fig. 76b). Males and females differ from all other Nyssus species, except for the very distinctive N. coloripes, in that there is no distal constriction on femora III, IV (Fig. 75b).
Etymology. The species is named in honour of Mr Jared Warden, an avid spider enthusiast who collected and donated the types.
