description: Brignoliella besutensis sp. nov.
Figs 1–3
Type material: Holotype: male (SMF), Malaysia, Kuala Terengganu, Besut, under stone, leg. J. Wunderlich, vend. August 2008. Paratype: 1 male, with same data as for holotype.
Etymology. The specific name refers to the type locality; noun in apposition.
Diagnosis. This new species is similar to B. caligiformis Tong & Li 2008 from Hainan Island, China (see Tong & Li 2008: fig. 2A–C, F–G), but can be distinguished by the non-inflated tibia (Figs 2A, 3A), the pear-shaped bulb (Figs 2B, 3B), the horn-shaped embolus (Figs 2C, 3C; boot-shaped in B. caligiformis), and the slightly sinuous course of the sperm duct (more strongly bent and with almost right-angled part in B. caligiformis).
Description. Male (holotype). Colouration: Prosoma reddish-brown (Figs 1A–D), opisthosoma (1E–F) and legs pale reddish-brown to yellowish-brown.
Measurements: Total length 1.13. Prosoma length 0.57, width 0.45, height 0.45. Opisthosoma length 0.71, width 0.57, height 0.48. Clypeus height 0.13. AME 0.054, ALE 0.059, PLE 0.059. Sternum length 0.32, width 0.30. Legs: I 1.20 (0.39, 0.13, 0.27, 0.20, 0.21); II 1.09 (0.34, 0.13, 0.25, 0.18, 0.20); III 0.99 (0.30, 0.13, 0.21, 0.18, 0.18); IV 1.27 (0.40, 0.13, 0.30, 0.22, 0.21).
Prosoma: Dorsal shield strongly sclerotised. Cephalic part smooth, slightly elevated, with two rows of wartlike knots (likely setae lost) behind ocular area. Thoracic part irregularly reticulate, margin rugose and denticulate. Ocular area situated anteriorly, with six eyes in three diads, PME absent. AME<ALE=PLE in eye size. Each right and left ALE and PLE contiguous as AME. Clypeus with few wart-like knots, anterior margin bilobate concave, clypeal horn short, distally bifid. Chelicerae surface smooth, fronto-mesal cheliceral horn short, cheliceral laminae developed, translucent. Gnathocoxae basally wide, distally narrow. Labium distally blunt, subtriangular. Sternum almost as long as wide, with relatively large wart-like knots, marginally crinkled.
Legs: All with lateral veins. Leg formula: IV-I-II-III.
Opisthosoma: Dorsal scutum short ovoid, with sparse small pits. Ventral scutum anteriorly slightly crinkled, posteriorly with pits, booklung cover smooth. Lateral scutum I long, and not exceeding anterior margin of pre-anal plate. Postgenital plate present, pre-anal plate rectangular and smooth.
Pedipalp (Figs 2–3): Femur ventrally granulated, with three long setae. Patella about half as long as tibia, without modification. Tibia slightly bent, with a distal trichobothrium dorsally. Cymbium sub-triangular in lateral view. Bulb pear-shaped. Spermophor course simple. Embolus short, sclerotised, distinctly narrowed and slightly bent distally, horn-shaped.
Female: Unknown.
Distribution. Known only from the type locality.
