Etymology.
Refers to the
type
locality.
Diagnosis.
Known from the west slopes of the Andes, in contrast to the similar
T. cosanga
, which is known from the east. The palp can be distinguished from that of
T. cosanga
by a wider tip of embolus (
Fig. 30
) and slightly more delicate median apophysis (
Fig. 32
). Unlike both
T. cosanga
and
T. parocula
, the abdomen has a pair of pale spots in the distal third (
Figs. 46–47
). Like
T. cosanga
,
T. bellavista
differs in many respects from
T. parocula
, including the smaller median apophysis, embolus with a single curve, cymbium clothed entirely in white setae (compare
Fig. 43
and
51
), paler base of the first leg metatarsus (compare
Fig. 43
and
48
), and epigynal opening more anteriorly placed.

Description.
Male
(
holotype
). Carapace length 2.4; abdomen length 2.6. PME large. Chelicerae not particularly enlarged, with 3 promarginal and 2 retromarginal teeth. Palpus (
Figs 30–32
): as in
T. cosanga
, though tip of embolus wider and median apophysis less robust. Tibia of first leg with 3 pairs of ventral macrosetae; first metatarsus with 3 prolateral and 2 retrolateral setae. Colour (
Figs 43, 44, 46
): In general dark brown, as in
T. cosanga
. First legs darkest. The bases of the first leg metatarsus and tarsus are especially pale in contrast with the rest of the leg. The abdomen has, in addition to faint chevrons, two lateral pale spots in the posteriormost third.
