T1 length 2.78–3.78× its apical width.

Biology/ecology. Malaise-trapped at high-altitude grasslands.

Distribution. Brazil, Minas Gerais state.

Etymology. The name refers to the origin location of this species: the Serra Fina Mountain, in Itamonte, MG, Brazil.

Comments. This species is most similar to Coelinius calcara ( Riegel, 1982) . It differs by having head as wide as long ( calcara , wider than long); frons concave and rugose ( calcara , slightly concave and punctate); notauli crenulate ( calcara , rugulose); mesoscutum smooth and shiny ( calcara , shiny and shagreened); mesopleuron smooth ( calcara , shinning, shagreened, rugose both on anterodorsal quarter and posterior end); body color predominantly black to dark brown ( calcara , reddish-brown).
