urn:lsid:zoobank.org:act: 8016A2A6-BA64-4AC3-99F1-DA6E892F7D87

TYPE MATERIAL. — Holotype. Peru • ♀; Cuzco, road up to MachuPicchu ruins; in forest; 2100 m a.s.l.; 20.II.1965; Herbert W. Levi leg.; MCZ-75998.

ETYMOLOGY. — The specific epithet is a Latin adjective, meaning ‘uniform’ and refers to the overall homogenous colouration of the opisthosoma; the gender is feminine.

TYPE LOCALITY. — Machu-Picchu, Peru.

DISTRIBUTION. — Only known from the type locality.

DIAGNOSIS. — The female of Linothele uniformis n. sp. can be distinguished from those of most other species of Linothele by its undivided scopula. It resembles females of L. fallax, but differs from them by the absence of patterns on the opisthosoma, a significantly lower number of maxillary cuspules (Fig. 16A) and its spermatheca stalks not bearing a single retrolateral lobe (Fig. 16D).
