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. Fig. 11B with figs 13E and 124 in Wesołowska & Russell-Smith 2000).
