NOTE: The specimens from Brazil are slightly different in palpal morphology from the ones in Ecuador and Peru (see “Variability”); that is here considered as intraspecific variability, but future studies with additional material and females may show that these are two different species.  
ETYMOLOGY: A noun in apposition; “El Golem” (“The Golem”) is a poem of the Argentinean writer Jorge Luis Borges. In Jewish folklore, a golem is an animated anthropomorphic being, created entirely from inanimate matter.  
DIAGNOSIS: Males can be distinguished by the copulatory bulb, with a long and strong embolus and a cuticular outgrowth near base, in dorsal and prolateral view (fig. 95).  
MALE (PBI _OON 36475): Total length 1.23. Habitus as in figure 78A. CEPHALOTHORAX: Carapace as in figure 78 A, C. Labium rectangular, base with two sclerotized areas pointing to sternum (fig. 78B). Endites anteromedian tip with one strong, toothlike projection. ABDO- MEN: Pale orange, round. LEGS: Yellow; patella plus tibia I shorter than carapace. GENITALIA: Embolus long, strong; sperm duct coiled, with many loops (figs. 79, 95, 101).  
FEMALE: Unknown; females of morphospecies MI020–MI027, MI029, MI036, and MI038 from the same area are candidates to match this male.  
VARIABILITY: Males from Brazil have a copulatory bulb that is slightly different, with more sinuous embolus (compare figs. 95A–C and D–F).  
DISTRIBUTION: Known from the west Amazon region of Ecuador, the southern part of Peru and the state of Acre in Brazil (map 12).
