Diagnosis. Males of Patrera recentissima   are easily distinguished from the remaining species by the filiform median apophysis and embolus originating markedly from the base of the tegulum, forming a wide curvature in the male palp ( Figs 19C View FIGURE 19 , 20A View FIGURE 20 , 21B, C View FIGURE 21 ). Females are diagnosed by the epigynum with triangular hood and copulatory ducts comma-shaped as seem by transparence ( Figs 19F, G View FIGURE 19 , 20C, D View FIGURE 20 , 21F View FIGURE 21 ).

Abdomen: length 4.0, epigastric furrow 1.2 from tracheal spiracle, spiracle 1.4 from base of spinnerets. Palp: tibia shorter than cymbium, not curved; tibial retrolateral apophysis short, curved, forming an internal fold, with a scaly, striated border; cymbium oval; tegulum oval, with sperm duct slightly sinuous, near the retrolateral margin; tegular projection short, in the distal border of tegulum; median apophysis, subdistal, curved at apex; very slender embolus, with narrow base ( Figs 19C–D View FIGURE 19 , 20A, B View FIGURE 20 , 21B–E View FIGURE 21 ).

Female ( MCN 20503 View Materials ). Carapace brownish, darker in the cephalic region ( Fig. 19B View FIGURE 19 ). Chelicerae dark brown. Labium and endites brown. Sternum yellowish. Legs yellow, darkest from tibiae to tarsi. Abdomen grayish; ventrally yellow ( Fig. 19B View FIGURE 19 ). Total length 7.7, carapace length 3.2, width 2.1. Clypeus height 0.14. Eye diameters and interdistances: AME 0.08, ALE 0.12, PME 0.12, PLE 0.12; AME–AME 0.10, AME–ALE 0.08, PME–PME 0.20, PME–PLE 0.18, ALE–PLE 0.10.

Abdomen: length 4.3, epigastric furrow 1.4 from tracheal spiracle, spiracle 1.1 from base of spinnerets. Epigynum: lateral borders narrow, connected laterally with the anterior border of epigynal plate; small, triangular atrium; sclerotized hood; internally with short and convolute copulatory ducts; anterior, globose seminal receptacles, in the proximal area of the copulatory ducts; oval spermathecae; fertilization ducts shorter than spermathecae, curved, basal ( Figs 19F, G View FIGURE 19 , 20C, D View FIGURE 20 , 21F View FIGURE 21 ).
