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 a country girl, who is always wearing a red dress and a pair of pigtails in her hair. She never walks barefoot and she often speaks wrongly like a hick from the interior of Brazil.
Diagnosis.
Ochyrocera rosinha sp. nov. is distinguished from the other species of Ochyrocera from the Quadrilátero Ferrífero by having a cymbium with a long apex, aciculiform cuspule, long and narrow palpal tibiae and filiform embolus, longer than cymbium (Figs 11C, D View Figure 11 , 13A, B View Figure 13 ). The female of Ochyrocera rosinha sp. nov. differs from other species by its short and reniform spermathecae and very large pore plates (Fig. 13C, D View Figure 13 ).
Description.
Male (Holotype, IBSP 196435a). Total length 1.4. Carapace length 0.5, ovoid; gradually narrowing anteriorly; yellowish-white, pars cephalic flat, fovea absent (Fig. 11A View Figure 11 ). Clypeus length 0.03, with pair of long bristles. Eyes: with black edges (Fig. 11A View Figure 11 ), PME oval, slightly larger than others; ALE and PLE rounded. Chelicerae white with yellowish fang; promargin with 6 teeth attached to very long lamina; retromargin without teeth. Endites cream, 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. Legs: cream; formula 1423; total lengths: I 5.3; II 4.9; III 4.4; IV 5.1. Male palp: palpal femur length 0.05; palpal tibia as long as cymbium, not curved; cymbium strongly tapered at tip, bearing long and thin apical cuspule; retrolateral paired long setae on non-projected base, tarsal organ subdistal, with non-elevated base and bifid and elongated proprioceptor, with three basal setae on rounded cymbial prolateral extension; bulb oval; embolus longer than cymbium, tapering to apex (Figs 11C, D View Figure 11 , 13A, B View Figure 13 ). Abdomen length 0.8, oval; uniformly yellowish-white (Fig. 11A View Figure 11 ). Six epiandrous spigots with short base.
Female (paratype, IBSP 196435b). Total length: 1.5; carapace length: 0.5. Carapace as in male, white (Fig. 11B View Figure 11 ). Pedipalp without claw, with conical tip and subdistal tarsal organ (Fig. 12E, F View Figure 12 ). Clypeus: diameter 0.03, with three pairs of long bristles (Fig. 12A View Figure 12 , broken in the photo). Eyes, chelicerae, sternum, endites, and labium (Figs 11B View Figure 11 , 12A-D View Figure 12 ) as in male. Legs as in male; formula 4123, total lengths: I 5.2; II 5.0; III 4.2; IV 5.4. Internal genitalia with short and enlarged spermathecae under conspicuous pore-plate; medial columnar uterus externus, no visible chambers internally. Uterus externus ending in narrow neck. Oval pore-plates on spermathecae with approximately 30-40 glandular ducts (Fig. 13C, D View Figure 13 ). Abdomen length 0.8 (11B). Colulus triangular with approximately 8 bristles.
Variation.
Males (n=4): total length 1.2-1.4; carapace 0.5-0.6; femur I 1.7-2. Females (n=10): total length 1.3-1.6; carapace 0.5-0.7; femur I 1.5-1.8.
Distribution.
Known from the Lapa do Grotão cave system and SPT_0316 cave located in Southern Serra do Espinhaço, municipality of Morro do Pilar, state of Minas Gerais, Brazil (Fig. 14 View Figure 14 ). The Lapa do Grotão cave system, unlike the vast majority of ferruginous caves, is part of a perennial drainage system. This system is formed by two large caves (MP-0001A with 290 meters and MP-0001B with 451m) separated by a large doline (large circular doline with a diameter of approximately 45 m and a depth of 30 m). Both caves develop in the contact zone between iron formation rocks (itabirite) and siliciclastic rocks (quartzites). The system is located in an area of riparian forest and is associated with the Lages stream, which is mainly responsible for contributing organic matter to the underground environment. The system receives part of the flow from the Lages stream, which drains towards a sink located in its central west portion where there is a large well ( Coelho and Leão 2015). In addition to O. rosinha sp. nov., several other troglomorphic species were found in this cave (R. Zampaulo, pers. obs.). Of these, only the harvestman species Gonycranaus pluto Bragagnolo, Hara & Pinto-da-Rocha, 2015 ( Gerdesiidae , Opiliones) has been described so far.
