Ambientalcol.  Etymology. Noun in apposition is a tribute to the fictional character of the Brazilian "Turma da Monica"comic books by Mauriciode 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 monicasp. nov. is distinguished from the other species of  Ochyrocerafrom the Quadrilatero Ferriferoby 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 monicasp. nov. differs from other species by its large and elongated spermathecae and narrow and smooth columnar uterus externus (Fig. 9H, I).   Figure 9.  Ochyrocera monicasp. nov., male (IBSP 196681) Ahabitus, dorsal view Bpalp, prolateral view Csame, retrolateral view Dsame, retrolateral view Esame, prolateral view Fhabitus, dorsal view, female (IBSP 196676) Gepigynal plate, ventral view Hinternal genitalia, dorsal view Isame, enzyme cleared, dorsal view.
