For both males and females, the carapace ranges in color from dull yellow to orange brown, and is covered with black, subpretiated bristles. The cephalic part ranges from dark orange-brown to reddish-brown, forming a U-shape that contrasts with the yellowish thoracic part. The eye tubers are enlarged, and the lateral margins are not dark. The abdomen is either grayish or darkened, with the dorsal portion darker than the ventral portion. Leg segments range in color from orange-brown to reddish-brown. Loxosceles intermedia is native to Brazil and Argentina. It occurs in temperate and warm regions of South America, specifically in southeastern and southern Brazil, and northern Argentina. This species lives in dark, very dry cracks in warm regions at elevations below 500 m, and is quite commonly found around or inside human houses.
