Description. Male. Eyes separated (Fig. 34), C-shaped. Minimum distance between upper part of eyes hardly as wide as diameter of facet. Eye bridge formed by four rows of facets. Frontoclypeus with large central three-lobed patch of insertions of hairs, lateral lobes touching inner margin of eyes, medial stripe longest, narrowly connected with vertex pits. Antenna with 15 antennomeres. Scape shortly cylindrical, 1.3 times as long as pedicel, with broader proximal part in contrast to basal one. Flagellomeres pitcher-shaped, almost symmetrical. Last three flagellomeres fused (Fig. 41), decreasing in size, without necks, terminal flagellomere minute, ovoid. Sensory filaments (ascoids) paired, with three branches. Length ratio of maxillary palpomeres 1.1: 1.1: 1.0: 1.3, palpomere 4 not annulate. Terminal lobe of labium with five digital protuberances. Maximum length of cibarium equal to 1.1 times length of epipharynx (Fig. 37).

Thoracic sclerites as in Fig. 51, anepisternum with 17 hairs. Wing (Fig. 38) widely lancetshaped, 1.5 mm (holotype) and 1.2–1.5 mm (paratypes) long, inconspicuously clouded, dark patches and tufts of hairs at tips of most veins conspicuous, excluding Sc and R 5. Following veins or their parts strengthened: Sc, whole R 1, R 2 and R 3 distally, R 4 basally, R 5, M 1+2 basally, M 4, and Cu basally. Basal costal nodes well visible, Sc uninterrupted. M 3 and Cu hardly with connection to M 4; R 5 extends in apex of wing. Medial wing angle 120° (BCD). Wing indices: AB: AC: AD = 3.9: 4.1: 3.3; BC: CD: BD = 1.0: 2.0: 2.6; maximum length of wing equal to 2.4 times its maximum width. Maximum length of haltere (Fig. 44) equal to 2.7 times its maximum width.

Ratios of lengths of femora, tibiae and first tarsomeres: P 1 = 2.4: 2.3: 1.0; P 2 = 2.5: 2.9: 1.1; P 3 = 2.8: 3.2: 1.2.

Basal apodeme of male genitalia (Figs. 47, 54) narrow and thin from strictly dorsal view, expanded proximally from lateral view; distal part of basal apodeme forked in two caudal arms. Copulatory organ long, narrow, widened and rounded distally (Figs. 47, 54–56). Gonocoxite (Figs. 47, 53, 54) cylindrical, prolonged, with conspicuous protuberance laterally. Gonostylus (Figs. 45, 47, 53) as long as gonocoxite, slightly S-shaped or conspicuously bent from different views, with extremely protruding comb of four stiff setae basally and acuminate apex with several small and soft setae. Epandrium (Figs. 46, 48) with two large patches of hairs connected caudally, inside with two conspicuous spine-shaped protuberances, sclerotized remainders of tergite and sternite 10 missing. Central aperture developed. Hypandrium (Fig. 47) strengthened in middle part, approximately oblong-shaped, with slightly divergent sides. Epiproct and hypoproct small, hairy (Fig. 48). Surstylus (Figs. 46, 48) long, almost twice as long as epandrium, C-shaped from dorsal view, hardly straight from lateral one, subapically with one retinaculum.

Female. Frons a little broader than in male and medial stripe of insertions of hairs broadly connected with vertex pits (Figs. 26, 35). Antennae on Figs. 40 and 49; sensory filament on Fig. 50. Length ratio of maxillary palpomeres 1.0: 1.2: 1.1: 1.4 (Fig. 43). Terminal lobe of labium as in Fig. 42. Cibarium (Figs. 26, 36) of the same size as in male. Thoracic sclerites as in Fig. 27, anepisternum with 11 hairs. Wing (Fig. 39) similar to male, 1.5–1.9 mm (paratypes, including allotype 1.9 mm) long, dark patches and tufts of hairs conspicuous only at tips of M 3, M 4 and Cu, slightly at tips of R 2 and R 3. Medial wing angle 104° (BCD). Wing indices: AB: AC: AD = 3.5: 3.8: 2.9; BC: CD: BD = 1.0: 1.8: 2.3. Ratios of lengths of femora, tibiae and first tarsomeres: P 1 = 2.7: 2.5: 1.0; P 2 = 2.7: 3.1: 1.2; P 3 = 3.2: 3.9: 1.3. Fore claws as in Fig. 52. Subgenital plate of characteristic shape (Fig. 58), formed by extremely wide basis, connected with V-shaped lobe by very narrow slip bridge (caudal cleft of lobe is shallow and inconspicuous). Plate with numerous closely-spaced hairs and several long setae distally. Genital chamber as in Figs. 31–33, cerci rather long and bent (Figs. 28–30, 57).

Differential diagnosis. The hypandrium of Tinearia boliviensis sp. nov. (male) is conspicuously expanded (Fig. 47), rectangular, epandrium inside with two big spine-shaped apodemes (Fig. 48), insertions of epandrial hairs regularly spaced (two-spoted configuration missing, dorsal view), epandrial aperture developed (Figs. 46, 48), gonostyli basally with conspicuous spined tubercle (comb) – Figs. 45, 47 and 53. Subgenital plate (female) with extremely wide basis (Fig. 58), very narrow in the middle, connected with a constriction of V-shaped lobe (caudal cleft of the lobe is very shallow and practically inconspicuous).

Tinearia capitipenis (Ibáñez-Bernal, 1992), comb. nov., differs by a narrow hypandrium, epandrium inside without spine apodemes and at the surface with two-spoted configuration of hairs, epandrial aperture missing, gonostyli basally with a small spined tubercle. Female subgenital plate of quite different shape, with a middle-distal cleft about 0.25 as deep as the greatest length and two basilateral lobes (Ibáñez-Bernal, pers. comm. and his new additional unpublished figures).

Etymology. The new species name (adjective) is based on the country of origin.

Biology and collecting circumstances. Circuata has a presence of many small forsaken mines in the forest underneath (Fig. 84); valley embanked with very humid steep banks (Fig. 80). Leishmaniasis is sporadic.

Distribution. Bolivia: Subandean region.
