Etymology. Noun in apposition is a tribute to the fictional character of the Brazilian "Turma de Monica" comic books by Mauricio de Sousa, based on his daughter Magali. She is 7 years old and her main characteristic is her voracious appetite. She eats everything, at high speed, and feels hungry all the time, but despite this, friends see her as skinny, without ever putting on weight. Diagnosis. Ochyrocera magali sp. nov. differs from other species of Ochyrocera by the male having conspicuous elongated setae on the border of the sternum (Fig. 6B, C ), a long and apically projected embolus with curved tibiae of the male palp (Figs 6D, E , 8A, B ). The female of Ochyrocera magali sp. nov. resembles O. dorinha sp. nov. by its long ducts and globose spermathecae (Fig. 5C, D ) but differs by its small pore plate and not coiled ducts of the spermathecae in the genitalia and lateral pockets small and elongated (Fig. 7E, F ).

Female (Paratype, IBSP 196412b). Total length 1.0; carapace length 0.4. Carapace as in male (Fig. 7A ). Pedipalp without claw, with conical tip and subdistal tarsal organ, as in other species (Fig. 4C ). Clypeus: diameter 0.03. Eyes, chelicerae, sternum, endites, and labium as in male. Legs as in male; formula 4123, total lengths: I 1.7; II 1.9; III 1.4; IV 2.0. Colulus triangular with approximately 6-8 bristles. Epigynal plate slightly sclerotized, with sulcate lateral borders (Fig. 7D ), and small and elongated lateral pockets (Fig. 7E ). Internal genitalia with globose spermathecae with long ducts curved at base; short medial columnar uterus externus with no visible chambers internally and inconspicuous neck. Rounded and reduced pore-plates with approximately 15-20 glandular ducts (Fig. 7E, F ). Abdomen slightly grey, length 0.5 (Fig. 7A ). Variation. No variation was found between the specimens. Distribution. Known only from four ferruginous caves in the municipalities of Caete and Santa Barbara , in the Quadrilatero Ferrifero , state of Minas Gerais, Brazil (Fig. 14 ).
