Etymology.

Noun in apposition is a tribute to the fictional character of the Brazilian "Turma de Mônica” comic books by Maurício 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 View Figure 6 ), a long and apically projected embolus with curved tibiae of the male palp (Figs 6D, E View Figure 6 , 8A, B View Figure 8 ). The female of Ochyrocera magali sp. nov. resembles O. dorinha sp. nov. by its long ducts and globose spermathecae (Fig. 5C, D View Figure 5 ) 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 View Figure 7 ).

Description.

Male (Holotype IBSP 196412a). Total length 0.8. Carapace length 0.45, ovoid; rounded anteriorly; pars cephalic white, flat; fovea absent (Fig. 6A View Figure 6 ). Clypeus length 0.03, with pair of long bristles (Fig. 6A, B View Figure 6 ). Eyes: with black edges, PME oval; ALE and PLE rounded, all approximately the same size. Chelicerae paturon white with yellowish fang; promargin with 6 teeth attached to a long lamina; retromargin without teeth. Endites white with large serrula with more than 30 denticles, distal macrosetae paired and crosier-like, many multifid macrosetae present. Labium white, rounded with 6-8 setae with enlarged base. Sternum white with long, thin setae on posterior edge (Fig. 6B, C View Figure 6 ). Legs: light grey; formula 1423; total lengths: I 1.8; II 1.6; III 1.4; IV 1.7. Male palp: palpal femur length 0.03; palpal tibia longer than cymbium, slightly curved (Fig. 8A, B View Figure 8 ); cymbium slightly curved dorsally, bearing short apical cuspule (Fig. 6D View Figure 6 , 8A, D View Figure 8 ); retrolateral paired long setae on non-projected base, tarsal organ subdistal, with non-elevated base and bifid and elongated proprioceptor (Fig. 8A, E View Figure 8 ); three basal setae present on rounded cymbial prolateral extension (Fig. 8C View Figure 8 ); bulb oval; embolus flattened, very long, apically projected, with sinuous tip (Figs 6D, E View Figure 6 , 7B, C View Figure 7 ). Abdomen length 0.35, oval; uniformly yellowish-white (Fig. 6A View Figure 6 ). Six epiandrous spigots with short base.

Female (Paratype, IBSP 196412b). Total length 1.0; carapace length 0.4. Carapace as in male (Fig. 7A View Figure 7 ). Pedipalp without claw, with conical tip and subdistal tarsal organ, as in other species (Fig. 4C View Figure 4 ). 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 View Figure 7 ), and small and elongated lateral pockets (Fig. 7E View Figure 7 ). 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 View Figure 7 ). Abdomen slightly grey, length 0.5 (Fig. 7A View Figure 7 ).
