This epithet derives from the Latin adjective “ latus ”, meaning “broad”, referring to the broad brown band at proximal end of the abdomen. Diagnosis. The new species resembles Mughiphantes jaegeri Tanasevitch, 2006 (Figs 213, 214; Tanasevitch, 2006, figs 25–28), but can be distinguished by the distal part of paracymbium C-shaped, where the distal tip touches the retrolateral margin of cymbium in M. latus sp. nov. (Fig. 213B), whereas V-shaped, and the tip of the paracymbium does not touch the retrolateral margin of cymbium in M. jaegeri (Tanasevitch, 2006, fig. 25). Lamella characteristca with two branches in M. latus sp. nov. (Fig. 213A–C), whereas with three branches in M. jaegeri (Tanasevitch, 2006, fig. 25). Proximal cymbial apophysis somewhat rectangular in M. latus sp. nov. (Fig. 213B, D), whereas V-shaped in M. jaegeri (Tanasevitch, 2006, fig. 25). Posterior median plate rectangular with a depression posteriorly in M. latus sp. nov. (Fig. 214C), whereas V-shaped in M. jaegeri (Tanasevitch, 2006, fig. 28). Description.
