Description.
MALE: Measurements (n =10) DSW: 4.6-5.5 (5.5); DSL: 5.0-5.8 (5.6); CL: 1.1-1.5 (2.2). FIVL: 10.8-12.4 (12.4). ChL: 1.7-5.2. Coloration: (Fig. 24C View Figure 24 ) Body reddish brown. Dry-marks on the carapace, grooves of dorsal scutum and free tergites. Pedipalpus , chelicerae and legs brown. Dorsum: (Fig. 6A View Figure 6 ) Anterior margin of carapace with median elevation, with a few sparsely distributed granules. Ocularium with median saddle-shape depression; a pair of short median spines, and two pairs of tubercles near the eyes; slightly granulate. Carapace with scattered tubercles. Areas I-IV covered with scattered tubercles. Area I divided; with a pair of small median tubercles. Area II invading area I; unarmed. Area III with two long parallel spines, directed posteriorly, located at elevations of integument, totally granulate. Area IV unarmed. Posterior margin of dorsal scutum with two median acuminate tubercles and two small granules. Free tergites I-III with a pair of acuminate tubercles, medially in tergites I-II and laterally in tergite III. Chelicerae: (Fig. 6A View Figure 6 ) Conspicuously swollen in large males (as in the holotype), to a lesser extent in smaller males. Segment I granulate. Segment II with few granules; finger with three teeth. Segment III with one tooth. Pedipalpus : Granules on the ventral surface of the femur. Trochanter with a ventroapical setiferous tubercle. Femur with a ventral row of nine large setiferous tubercles (except at the apex), larger in the middle portion; one proapical spine. Patella with a small proapical setiferous tubercle. Tibia: prolateral iIiI, retrolateral IIII. Tarsus: prolateral iIiIi, retrolateral iII. Venter: Coxa I with two rows with 6-7 large tubercles. Coxae II-III with two rows of granules. Coxa IV with scattered granules. Row of five small tubercles between the coxae III-IV. Genital area slightly granulate. Free sternites with few granules. Anal operculum granulate. Legs: (Figs 6A View Figure 6 , 11C, D View Figure 11 ) Coxae I-II each one with a prolateral and a retrolateral apophyses. Coxa III with a prolateral apophysis Coxa IV with setiferous granules sparsely distributed throughout its surface; unarmed. Trochanters I-III unarmed and with sparse granules. Trochanter IV with few granules; a large retroapical apophysis; two small retrolateral tubercles medially near the retroapical apophysis. Femora I-III with small granules. Femur IV with granules sparsely distributed throughout its length; a retrolateral row of 24-26 acuminate tubercles varying in size throughout femur length. Patellae I-IV unarmed, with few granules. Tibiae I-III few granulate; unarmed. Tibia IV with a retrolateral row of 15-16 acuminate tubercles, covering the entire length of segment; two dorsal small tubercles. Tarsal segmentation: (n =5) 9-10 (10), 20-23 (23), 11-12 (12), 11-15 (14). Penis: (Fig. 17D-F View Figure 17 ) VP rectangular, with distal margin straight; a distal median projection with half the width of VP; Ventral plate strongly thick and straight in lateral view. MS C1-C6(C7) subapical long and well curved; MS A1-A2 median to sub basal, long and straight; MS D1 very short and straight, dorsally placed near MS A. Lateral sacs long, apically tapered; with short T3-like microsetae. Stylus elongate and flattened laterally, with lateral supapical filiform projections. Dorsal process absent. Promontory slightly convex. - FEMALE: Measurements (n =10) DSW: 4.9-5.3; DSL: 5.3-5.5; CL:1.0-1.2. FIVL: 11.5-12.5. ChL: 2.3-2.7. (Fig. 24D View Figure 24 ) Chelicerae not swollen, smaller or equal to the small males. Areas of the dorsal scutum more granular than that of males. Trochanter IV with retroapical apophysis shorter than the male; without prominent tubercles. Femur IV unarmed. Tarsal segmentation: (n =10) 8, 19-21, 11-12, 12-13.
Diagnosis.
Similar to Lumieria woodyalleni gen. et sp. nov. because ocularium is armed with a pair of spines, area I divided, area III with a great pair of spines, free tergites with large tubercles (Fig. 6A View Figure 6 ) and femur-tibia IV with a retrolateral row of acuminate tubercles (Fig. 11C, D View Figure 11 ). Differs from Lumieria woodyalleni gen. et sp. nov. because the area II invading the area I; increased granulation on carapace and areas of dorsal scutum (Fig. 6A View Figure 6 ); male femur IV with less than 20 retrolateral acuminate tubercles (Fig. 11C, D View Figure 11 ); VP with distal margin straight and with a distal median projection (Fig. 17D-F View Figure 17 ).
Derivatio nominis.
The specific epithet of masculine gender, in the genitive form, dedicated to the Italian filmmaker, editor, screenwriter, painter and writer Michelangelo Antonioni (1912-2007).
