Dissonulichen (Dissonulichospinus) Cadena-Castañeda n. subgen.

Diagnosis. This subgenus differs from Dissonulichen s.s. by the following characters: fastigium broad at its base, prominent frontal ocellus, hind femur with a laterally expanding, lamelliform spine (absent in Dissonulichen s.s.) with undulating outer edge, similar in shape to Dysonia , but not as prominent ( Fig. 25A ).

Distribution. Southeastern Brazil, with one record from the northeast ( Map 12 ).

Taxa included. Dissonulichen (Dissonulichospinus) elegans ( Brunner von Wattenwyl, 1878) n. comb. (type species),

D. (D.) ornatus ( Piza, 1951) n. comb. and D. (D.) diffusus ( Piza, 1981) n. comb.

Etymology. Derived from the name of the genus which means “false lichen”, with reference to the peculiar spine on the hind femur. The gender is masculine.
