EYES: AME: 0.16; ALE: 0.23; PLE: 0.15; PME: 0.11; interdistances: AME: 0.01; AME-ALE: 0.07; PME: 0.39; PME-PLE: 0.03; LE: 0.03; ocular quandangle 0.77/ 0.85/0.31. ABDOMEN: oval, dark gray dorsally and light gray ventrally ( Fig. 9A, B View FIGURE 9 ). Spinnerets: median spinnerets: 0.48; lateral spinnerets: 0.84/0.47/0.66. LEGS: Orange-brown except legs I–II with black markings. Coxae I–II with inner short stiff setae. Metatarsi I–II with apical scopulae; tarsi I–II with complete scopulae ( Fig. 10D View FIGURE 10 ); III–IV without scopulae. LEGS MEASUREMENTS: I 10.15 (3.16/1.70/2.46/1.71/1.12); II 8.70 (2.68/1.20/2.08/1.64/1.10); III 5.92 (2.03/0.98/0.98 /1.05/0.88); IV 10.32 (2.92/1.35/2.80/2.00/1.25); leg formula: 4123. GENITALIA: See Rudolph (1996: fig. 5).

Distribution. Only known from Cuba.

Natural History. Specimens were collected in mountain pine forests. Females build 20 to 25cm long tubeshaped burrows without covers, covering the entire interior with silks (Rudolph 1996).

Note. Bolostromus holguinensis was described by Rudolph (1996) the female holotype was deposited in Cuba, one paratype was deposited in Berlin (ZMB), and one paratype in Dessau (MNVD), Germany. The specimen in Dessau is currently misplaced and could not be found, the specimen from Berlin was the only one available, the redescription of the species is based on the paratype specimen from Berlin which is unfortunately juvenile.
