Differential diagnosis
Dorsal ocular width subequal to one-sixth interocular distance; anteromedial pronotal edge curvature tends to be continuous; posterior pronotal surface uniformly punctate; elytral interstriae punctation tends to be visible at 10 × magnification; metasternal depression divided anteriorly. ♂ pronotal ridge with two sets of distinct bilaterally paired tubercles in large individuals; paramere apex evenly rounded; FLP endophallite elongate, with two indentations along right edge.
Etymology
Williami is the Latin singular genitive form of William. This species is named in honour of the second author’s brother, William Darling.

Female allotype ( Figs 12 View Figs 9–12 , 24 View Figs 21–24 )
Similar to male with the following exceptions: Body length 14.3 mm. Clypeofrontal carina transverse, centrally raised. Interocular surface chagrined. Anterior pronotal ridge low, followed by shallow concavity.
Variation
Body length 13–19 mm. Small males with medially projecting clypeofrontal ridge instead of cephalic horn. Anteromedial pronotal edge evenly curved more often than indented. Pronotal ridge in small males low, medially notched. Elytral interstriae finely punctate (visible at 10 ×) more often than minutely punctate (invisible at 10 ×).
Distribution ( Fig. 66 View Fig )
Serra do Mar and Serra Geral Mountains in the Brazilian states of Rio de Janeiro, São Paulo, Santa Catarina, and Rio Grande do Sul, with recorded elevations from 800 to 1600 m.
Natural history
Specimens with data were collected in cloud and sub-montane Atlantic Forest. Some specimens came to carrion and dung traps, pitfall traps baited with human faeces and faeces of Tapirus Brisson, 1762 at elevations between 580 m and 1600 m.
