Figures 6 , 7 Type material. Holotype : ♂ : LIBERIA : Sinoe County , 05°08’N , 08°56’W , 27 January 2023 , leg. J. Timperley & B. Geninyan (LIB_ CAM _ BINCO _0004). Paratypes : ♂ : LIBERIA : Sinoe County , 05°05’N , 08°50’W , 21 January 2023 , leg. J. Timperley & A. Vincent (LIB_ CAM _ BINCO _0005) ; 1♀ : Sinoe County , 05°25’N , 09°03’W , 17 February 2023 , leg. J. Timperley & B. Geninyan (LIB_ CAM _ BINCO _0006) . Diagnosis. Crinopseudoa sinoensis sp. nov. males are most similar to those of C. bongella but are separated by: (i) RTA with a short thorn-like excrescence ventrally, (ii) RTA generally large with a slightly widened paddle-shaped apex, and (iii) CAPT long and rounded, well-projected ventrad ( Fig. 6D, E ). Females are easily diagnosed by the posterior central margin of the epigyne with a distinct wide U-shaped lip with lateral ridges ( Fig. 7C, D ). FIGURE 6. Crinopseudoa sinoensis sp. nov.

The specific epithet is derived from Sinoe , the region where this species was found. Description. Male ( holotype ; LIB_CAM_BINCO_0004). TL 4.02, CL 1.80, CW 1.64, SL 0.96, SW 1.00, AL 2.22, AW 1.48. Carapace light yellowish-brown, with black mottling, covered with small wart network. Eyes ringed with black, especially between AMEs and LEs . Fovea distinct. Legs generally lighter, with apical half of femora dark brownish. Sternum smooth. Abdomen greyish-brown, with dorsal scutum covering approximately 40% of abdomen. Pedipalp: RTA medium-sized, about 2/3 length of tibia, in ventral view directed straight anteriorly, slightly widened and paddle-shaped apically, spine-like excrescence basally about 1/3 total length of RTA. PTA very short and directed straight and prolaterally at 09h45 position. RAPT short and blunt, CAPT long with rounded semicircular apex, PAPT triangular, short, with anterior margin directed at 9 o’clock position. Embolus sickle-shaped, generally broad for much of its length. MA narrow in ventral view, protruding and deep in lateral view, cup-shaped ( Fig. 6B–E ). Leg spination: I: F- d1 pl1, Ti- v7-6, Mt- v4-4. II: F- d1, Ti- v6-6, Mt- v4-4. III: F- d2, Ti- d1-1, v1-1, Mt- d1-1, v1-1. IV: F- d2, Ti- d1-1, v1-1, Mt- d2-2, v2-2. Female ( paratype ; LIB_CAM_BINCO_0006). TL 4.88, CL 1.80, CW 1.60, SL 0.96, SW 0.98, AL 3.08, AW 1.80. Carapace light yellow-brown with black mottling, covered with small wart network. Anterior part slightly darker. Eyes ringed with black, especially between AME and LE. Fovea distinct, legs generally lighter with apical half of femora darker. Sternum smooth. Abdomen pale greyish, covered with very short, sparse setae, dorsal scutum absent ( Fig. 7A, B ). Epigyne: about twice as wide as long, circular ST clearly visible through integument positioned anteriorly, with ST heads directed medially towards each other. Broad, blunted Y-shaped incision at posterior margin ( Fig. 7C–G ). Leg spination: I: F- d1 pl1, Ti- v7-7, Mt- v4-4. II: F- d1, Ti- v6-6, Mt- v4-4. III: F- d2, Ti- d1-1, v2-2, Mt- d1-1, v2-2. IV: F- d2, Ti- d2-2, v1-1, Mt- d1-1, v2-2.
