Idiops tolengo Ferretti View in CoL sp. nov.
( Figures 12–13 View Figure 12 View Figure 13 )
Type material
Holotype female. Argentina, Santiago del Estero, Dique Los Quiroga (27°39′11.29″ S – 64° 21′40.89″ W), 6 January 1985, C. Szumik and P. Goloboff col. (MACN-Ar36723). GoogleMaps
Diagnosis
Females can be distinguished from those of the other Argentinean species of Idiops by the ~14 cuspules on labium and approximately 90 cuspules in maxillae ( Figure 12 View Figure 12 (b)), absence of prolateral and retrolateral spines on tarsi III and IV, and by spermathecae shaped like a golf club with apical receptacles directed inwards and approximately 2 times wider than ducts, which have a slightly median curvature and basal area highly sclerotised ( Figure 12 View Figure 12 (d)).
Etymology
The species is a name in apposition of ‘Johny Tolengo’, a famous TV character created and interpreted by the Argentine actor Juan Carlos Calabró (1934–2013). Johny Tolengo was a Buenos Aires socialite created in the TV show ‘Calabromas’ during the 1980s, representing a famous singer, and some of his songs were adopted by soccer fans.
