Vindullus Simon, 1880

Uindullus Simon, 1880: 288. Caporiacco 1955: 404 (implicit genus revalidation); Rheims & Jäger 2008: 221 (explicit genus revalidation).

Type species: Vindullus gracilipes ( Taczanowski, 1872) .

Diagnosis. Vindullus males are distinguished from those of all other Neotropical sparassid genera, except Macrinus Simon, 1887 , in having palps with a spiraled tegulum and a serrated projection ( Figs 2 , 5 , 7–11 ; Rheims & Jäger 2008: figs 12, 19, 25, 31; serrated keel in Rheims 2007: figs 21–22, 27–28, 33–34). They are distinguished from Macrinus males in having a rounded or triangular projection at the base of the embolus and a triangular projection at the base of the conductor ( Figs 2 , 5 , 7–11 , distal triangular projection in Rheims & Jäger 2008). Females are distinguished from those of the remaining Neotropical Sparassidae genera by the epigyne with median septum bearing an oval posterior blind ending atrium ( Fig. 23 ) and vulva with a hyaline internal duct system with two windings, the anterior (closest to copulatory opening) bearing a small, blind ending glandular projection ( Figs 24–26 ).

Description. For detailed description see Rheims & Jäger (2008).

Composition. Seven species: V. angulatus Rheims & Jäger, 2008 , V. concavus Rheims & Jäger, 2008 , V. fugiens ( O. Pickard-Cambridge, 1890) comb. nov., V. gibbosus Rheims & Jäger, 2008 , V. gracilipes ( Taczanowski, 1872) , V. guatemalensis ( Keyserling, 1887) comb. nov. and V. undulatus Rheims & Jäger, 2008 .

Distribution. Neotropical. Known from Guatemala to Brazil ( Fig. 27 ).

Uindullus spp., male, left palp, detail of tegulum, ventral view (7 U. angulatus Rheims & Jäger, 2008, 8 U. concavus Rheims & Jager, 2008, 9 U. gibbosus Rheims & Jäger, 2008, 10 U. gracilipes (Taczanowski, 1872), 11 U. undulatus Rheims & Jäger, 2008). C = conductor; E = embolus; PBC = projection at base of conductor; PBE = projection at base of embolus; SF = spiny field; SP = serrated projection (modified from Rheims & Jäger 2008).
