Fig. 7

Diagnosis

Based on the structure of the scape, notably reduced in its median and distal parts, as well as of the hypertrophied posterior median plate, the species belongs to the tropicalis group, and it is most similar to L. bituberculatus . Lepthyphantes bryocola sp. nov. can easily be distinguished from L. bituberculatus by the much wider distal broadening of the scape (Fig. 7B cf. Fig. 4H–I).

Etymology

The specific epithet is a latinized noun in apposition derived from a Greek root, ‘brya’ and Latin ‘ cola ’, together meaning ‘moss-dweller’.

Leg I 4.99 long (1.30 +0.33 +1.23 +1.25 + 0.88), IV 4.80 long (1.35 +0.30 +1.20 +1.20 + 0.75). Chaetotaxy. FeI: 0-1- 0-0, FeII–IV: 0-0-0-0; TiI–II: 2-1-1-4, III–IV: 2-1-1-1; MeI: 1-1-0-0, II–IV: 1-0-0-0. Length of tibial spines 1.5–2.5 × diameter of corresponding leg segment.

Median and distal parts of scape probably reduced, but was not dissected as only the holotype is known for this species. Entrance ducts running along the very edge of lateral wall of epigyne. Bursa copulatrix opening on internal side of scape widening. Posterior median plate with long and wide lateral branches covering entire aperture of epigyne from scape to lateral walls. Abdomen 1.45 long, 0.90 wide, dorsal pattern as in Fig. 7A.
