Etymology.

Noun in apposition is a tribute to the fictional character of the Brazilian "Turma da Mônica” comic books by Maurício de Sousa. She is one of the main characters, along with her friend Cebolinha. She is a girl of strong genius, who has no patience for the nicknames she receives from other children because of her physical appearance and usually responds to such actions with her extreme brute strength, far superior to that of a girl her age.

Diagnosis.

Ochyrocera monica sp. nov. is distinguished from the other species of Ochyrocera from the Quadrilátero Ferrífero by having cymbium with a conspicuous apical cuspule, enlarged palpal tibiae and elongated and sinuous embolus with a coiled tip (Fig. 9B-E). The female of Ochyrocera monica sp. nov. differs from other species by its large and elongated spermathecae and narrow and smooth columnar uterus externus (Fig. 9H, I).
