ETYMOLOGY. — The specific name is Latin for “terrible”, and refers to the complicated structure of the epigyne of this species. DIAGNOSIS. — The species resembles L . nigritus n. comb. and L . difficilis Wesołowska & Russell-Smith, 2000 , but may be easily distinguished by the shape of the copulatory openings and the longer seminal ducts (cf.

Brown and grey hairs cover carapace, long brown bristles in vicinity of eyes, short dense spines on eye field anteriorly. Small yellowishfawn scales around anterior eyes. Chelicerae brown, toothless, with long hairs on promarginal protuberance. Labium and sternum orange, maxillae orange with whitish tips. Abdomen rounded, squat, brownish-beige, ventrally light. Sparse long brown hairs on abdomen, denser at its anterior edge. Spinnerets yellow. Legs light brown, their hairs brown.
