Hadronyche L. Koch, 1873

Hadronyche L. Koch, 1873: 463 . Type species by original designation and monotypy, Hadronyche cerberea L. Koch, 1873 .

Diagnosis (from Gray, 2010). Tibia II either unmodified or with a blunt, rounded apophysis or apophyseal swelling; caput moderately to strongly raised and cheliceral paturon robust; male tarsi with two ventral spine rows.

Remarks. The 31 existing Hadronyche spp. show a substantial degree of diversity. Characters that vary across the genus include: number of cheliceral teeth, particularly in the central row; shape of labium and number of labial cuspules; relative width of palpal patella and femur; shape of apical segment of the PLS; modification of leg II; and shape of tarsi on legs III and IV (Raven, 2000; Gray, 2010). Gray (2010) divided the genus into four species groups based on these and other characters. The most morphologically distinctive of these groups is lamingtonensis .
