Description[]

According to Yamaguti & Pinto-da-ROcha 2009:

Male: Measurements (N = 2). Dorsal scutum: length, 6.4 (6.4); width, 6.9 (6.6); anterior margin width, 2.7 (3.1); posterior margin width, 4.5 (4.6). Leg lengths: I, 16.0 (16.1); II, 39.7 (41.3); III, 26.5 (29.0); IV, 61.3 (59.0). Femora lengths: I, 4.2 (4.9); II, 11.8 (12.6); III, 8.6 (9.2); IV, 18.6 (18.3).

Dorsum (Figs4, 23, 78, 105). Ocularium with median tubercle. Mesotergum with three areas: areas I and III with a pair of median tubercles. Free terg- ites II and III armed with median spines, with the spine of free tergite II being larger than that of free tergite III, or with median tubercles of similar size.

Legs (Figs 4, 42, 61, 79, 105). Coxa IV wide. Tro- chanter IV with two ventral median spines. Femur IV with a proximal ventral spine and a larger distal outer spine. Metatarsus IV with two longitudinal ventral rows of granules, curved apicad.

Penis (Figs86, 87). Dorsal process narrow and high. Apex of ventral process wide and fan-shaped, with the lateral edges turned back and the dorsal surface smooth. Ventral plate with three pairs of basal setae.

Coloration (in alcohol) (Fig. 105). Dorsal scutum light brown. Legs and pedipalpus dark brown. Posterior margin of dorsal scutum and free tergites each with a pair of lateral stains, white to light yellow, and irregularly shaped. According to the original descrip- tion (Roewer, 1930), the chelicera, pedipalpus, and legs I–III are light yellow, and ae very reticulated with black; leg IV is almost black, with only the metatarsus and tarsus in yellow.

Dry marks (Fig. 105). Present on the grooves, and with only a few white spots on lateral margins and median region of mesotergum. Y-shaped stain behind ocularium, with few spots.

Female: Unknown.

Comparison: Differs from other Bourguyiinae species in having light paired stains on each free tergite and posterior margin of scutum (Figs78, 105). Differs from other Bourguyia species in having ventral rows of small spines on the metatarsus IV (Fig. 79).
