Diagnosis. Patrera tensa   resembles P. pellucida   by the similar embolus and route of the sperm duct in the tegulum of male palp (as in Figs 22A View FIGURE 22 , 23A View FIGURE 23 , 24B View FIGURE 24 ) and having small hood in the female epigynum (as in Figs 22F View FIGURE 22 , 23C View FIGURE 23 , 24F View FIGURE 24 ), but differ by the absence of retrolateral basal projection in the cymbium, by the narrow retrolateral tibial apophysis which is fan-shaped at the apex and by the enlarged basal area of the median apophysis in the male palp ( Figs 11C–E View FIGURE 11 , 12A, B View FIGURE 12 , 13B–E View FIGURE 13 ). Females differs by the epigynum presenting small, triangular atrium, with parallel, not coiled copulatory ducts between the spermathecae ( Figs 11F, G View FIGURE 11 , 12C, D View FIGURE 12 ).

Abdomen: length 3.5, epigastric furrow 1.0 from tracheal spiracle, spiracle 1.1 from base of spinnerets. Palp: tibia as long as cymbium, slightly curved; tibial retrolateral apophysis with base slightly projected and scaly in the apex; cymbium oval; tegulum oval, with sperm duct sinuous at base; tegular projection short, not surpassing the distal border of tegulum; subapical median apophysis, curved at apex; furrowed, slender and curved embolus, originating at the base of the tegulum ( Figs 11C–E View FIGURE 11 , 12A, B View FIGURE 12 , 13B–E View FIGURE 13 ).

Female (IBSP 138589). Carapace yellow. Chelicerae yellow; labium, endites and sternum yellow. Legs yellow, darkest from tibiae to tarsi. Abdomen yellow with spots dorsal; ventrally yellow ( Fig. 11B View FIGURE 11 ). Total length 6.4, carapace length 2.7, width 2.0. Clypeus height 0.08. Eye diameters and interdistances: AME 0.08, ALE 0.12, PME 0.12, PLE 0.12; AME–AME 0.04, AME–ALE 0.04, PME–PME 0.12, PME–PLE 0.10, ALE–PLE 0.04.

Abdomen: length 3.6, epigastric furrow 1.3 from tracheal spiracle, spiracle 1.4 from base of spinnerets. Epigynum: lateral borders small, connected distally; small atrium; short and semicircular hood; internally with elongated and parallel copulatory ducts, short seminal receptacles, in the posterior portion of the copulatory ducts, reniform spermathecae; fertilization ducts short, curved, basal ( Figs 11F, G View FIGURE 11 , 12C, D View FIGURE 12 ).

Variation. Males (n=6): total length 6.1–7.5; carapace length 2.8–3.2; femur I length 4.1–4.4; Females (n=4): total length: 6.2–6.8; carapace length 2.6–2.7; femur I length 2.7–2.9.
