Ciniflella itatiaia sp. nov.

Figs 23–24 View FIGURE 23 View FIGURE 24 , 27

Diagnosis. Males are similar to those of C. armasi by having a moderately long embolus and a median apophysis with a small tooth on the concave mesal margin, but can be distinguished by lacking a retrobasal cymbial horn and the smaller RTA ( Figs 23C–E View FIGURE 23 , 24B–D View FIGURE 24 ) (with retrobasal horn and shorter median apophysis in C. armasi , Fig. 20D–F View FIGURE 20 ).

Types. Male holotype from Parque Nacional de Itatiaia (22°22′31″S, 44°39′44″W) [-22.37528, -44.66222], Itatiaia, Rio de Janeiro, Brazil, I–III.2015, L. Vieira & J. Louzada coll., deposited in IBSP 258687 View Materials GoogleMaps .

Etymology. The specific name is a noun in apposition taken from the type locality.

Description. Male (holotype). Carapace orange to reddish brown. Eye margins black. Chelicera orange, with four retromarginal teeth. Labium, endites and sternum cream. Legs yellow. Opisthosoma gray. Total length 3.8. Carapace 1.8 long, 1.4 wide. Clypeus 0.06 high. Eye diameters and interdistances: AME 0.08, ALE 0.12, PME 0.10, PLE 0.10, AME–AME 0.03, AME–ALE 0.05, PME–PME 0.03, PME–PLE 0.06, ALE–PLE 0.08, AME–PME 0;06. Leg measurements: I: femur 1.7/ patella 0.8/ tibia 1.6/ metatarsus 1.2/ tarsus 1.5/ total 6.8; II: 1.6/0.7/1.1/1.3/1.2/5.9; III: 1.3/0.6/0.8/1.2/0.6/4.5; IV: 1.9/0.6/1.6/2.0/1.0/7.1; Leg formula: 4123. Leg spination follows the genus pattern, except: tibia I–II v2-2-2-2, p1-1-0, r1-1-1; III v2-2-2-2; IV v2-2-2; metatarsus I–II p1-1-2, r0-01. Palp: RTA short, bifid; median apophysis slender, with a small tooth on the concave mesal margin ( Fig. 20F View FIGURE 20 ); tegulum with membranous tegular process near the base of embolus ( Figs 23C–E View FIGURE 23 , 24B–D View FIGURE 24 ).

Female. Unknown.

Variation. Six males: total length 3.0–4.0; carapace 1.6–2.0; femur I 1.2–1.7.

Other material examined. BRAZIL. Rio de Janeiro: Itatiaia, Parque Nacional de Itatiaia (22°22′31″S, 44°39′44″W) [-22.37528, -44.66222] GoogleMaps , 1♂ ( IBSP 258688 View Materials ; SEM) ; 1♂ ( IBSP 258692 View Materials ; no abdomen) ; 1♂ ( IBSP 258694 View Materials ; missing opisthosoma) .

Remarks. None of the collected males are in good condition. All of them suffered from drying out and half of them lost their opisthosoma due to poor conservation after collection.

Distribution. Known from Rio de Janeiro, southeastern Brazil.
