ETYMOLOGY: The species name, an adjective, refers to the peculiar shape of the male palpal tibia.

DIAGNOSIS: The new species can be easily recognized by the peculiar shape of the male palpal tibia.

DESCRIPTION: Male (paratype). Total length 1.63. Carapace 0.75 long, 0.63 wide, pale reddish brown, unmodified. Chelicerae 0.25 long, unmodified. Legs pale brown. Leg I 2.21 long (0.65+0.18+0.55+0.45+0.38), IV 2.19 long (0.65+0.18+ 0.58+0.45+0.33). Chaetotaxy 1.1.1.1, spines weak, their length about same as diameter of segment or a little longer. TmI 0.36. Metatarsus IV without trichobothrium. Palp (Figs 64-66): Tibia extended in dorso-ventral directions, with a narrow retrolateral outgrowth curved upward. Paracymbium very long, narrow, curved upward almost to a full circle. Distal suprategular apophysis massive, complex in shape. Median membrane very long, protruded forward and covering distal part of embolus. Radical part of embolic division elongated and lacking of outgrowths. Base of embolus wide, bent FIGS 64-67

180º, embolus very long, narrow, slightly curved distally. Abdomen 1.00 long, 0.65 wide, grey.

Female. Totallength 1.75. Carapace 0.73 long, 0.60 wide, unmodified. Chelicerae 0.30 long, unmodified. LegI 2.14 long (0.58+0.20+0.53+0.45+0.38), IV 1.71 long (0.48+0.20+0.38+0.35+0.30). TmI 0.34. Abdomen 1.20 long, 0.90 wide. Epigyne and vulva as shown in Figs 67, 115. Body and leg coloration, as well as chaetotaxy, as in male.

TAXONOMIC REMARKS: Paracymboides tibialis sp. n. is similar to P. aduncus sp. n.: their embolic division is almost identical. These species can be easily distin-

guished by the shape of the palpal tibia and of the distal suprategular apophysis. The female P. tibialis sp. n. differs from that of P. aduncus sp. n. by the absence of the twohumped outgrowth on the posterior side of the epigyne.
