with two spines in basal row, pala with 14-16 bristles in lower, 11-13 setae in inner and four long hairs in upper row (Fig. 5). Middle leg ratio femur:tibia:tarsus:claw = 0.65:0.26:0.30:0.39. Hind leg, ratio femur: tibia: tarsi: tarsll (including claw) = 0.48:0.32:0.32:0.26. Male. Fore leg, femur without a ventral spur, palar claw large, sub triangular (Fig. 5); ratio femur: tibia: pala = 0.26:0.13:0.12. Tergite VII with a sub circular patch of small bristles in dextrocephalic angle. Free lobe of left part of tergite VIII (Fig. 6) with about 15 bristles. Right paramere with a distinct apical knob (Fig. 8); left paramere with a broadly oval apical part (Fig. 7). Female. Fore leg, ratio femur: tibiopala 0.30:0.27. Receptaculum seminis (Fig. 9) elongate, large, about 0.3 mm long. Etymology - The species is named after its country of origin. Comparative notes - (See also key to subgenus Tenagobia below.) With the key to species of the subgenus Tenagobia in NlESER (1977) this species runs to couplet 4 of T. costaricana JACZEWSKI, 1930 and T. marmorata BERG ROTH, 1899. In both of these species the right paramere has a swelling under the apex which is lacking in T. boliviana (Figs 8, 10-11). T. pulchra HUNGERFORD, 1927 known from the Bolivian lowlands is larger (length of female 2.1-2.2, of male 2.1-2.3) and has a lower value of ocular index (female 1.2, male 1.3-1.4), its left paramere is similar to that of T. boliviana but the right paramere has a constriction below the apex (Fig. 12). Finally T testacea NlESER, 1977 from Ecuador and Colombia is also larger (length of male 2.0-2.2, of female 2.3) than T. boliviana and has the apical part of left paramere narrower and more elongate (Fig. 14).
