Types. Holotype: male from Oropuche River, Valencia Ward, Trinidad, Trinidad & Tobago [10.233333 ºN, 61.516667 ºW], 17.VIII. 1986, G.B. Edwards (FSCA). Paratypes: one female from Turare River, Valencia Road, Manzanilla Ward, Saint Andrew County, Trinidad, Trinidad & Tobago [10.65 ºN, 61.15 ºW], 19.VIII. 1986, G.B. Edwards (FSCA); one male and two females, same data as holotype (MPEG 21115 = ex-FSCA); one male from Rio Huanirila, La Paz, Bolivia [16.483333 ºS, 68.133333 ºW], 31.VII. 1993, A.D.

Etymology. The specific epithet, a noun in apposition, is the name of a famous oil on canvas painting by the Brazilian painter Tarsila do Amaral (1886‒1973). The male palp of this species resembles the disproportionate man depicted in the painting.
Diagnosis. Males of S. abaporu (Figs 30, 39) are similar to those of S. carinata (Figs 31, 40) by the developed paraembolic projection, but can be recognized by the distance between this and the embolus, which in S. abaporu is about three times the width of the embolus (as wide as the embolus in S. carinata). Females can be recognized by the reniform spermathecae (Fig. 122).
