Type locality: North side of Cerro Guaiquinima (1030 m elevation), Estado Bolívar, Venezuela.
|Types||Holotype: AMNH 136211|
|Diagnosis||Diagnosis: A Liophis of the cobella group (sensu Dixon, 1983: 149), distinguished from the geographically proximate L. c. cobella as follows: (1) by greater number of ventrals (168, 173 in 8 torrenicola, vs. 143-164, xc = 151.6 in cobella);'1 (2) by white to orange ventral surfaces in life (red in cobella fide Beebe, 1946, Dixon, 1983); (3) by a distinct pale neck ring (figs. 26-27, 28A) persisting into maturity (less well defined ring present or absent in juvenile cobella [fig. 28B, C in DONNELLY & MYERS 1991] but lost in adults); (4) by a juvenile pattern (faint in adult) on the side of the body showing alternating dark and light triangular bands (vague banding not triangular in young cobella, cf. fig. 28A-C). The laterally triangular juvenile blotches and the neck ring also may distinguish Liophis torrenicola from the two other named Venezuelan tepui species. Also, L. torrenicola has a dark-checkered venter with a considerable extent of pale ground color (figs. 26, 27), whereas L. trebbaui (Auyantepui) differs in having the ventral black markings forming broad transverse bands about the width of two ventral plates (fide Roze, 1958a, fig. 11 and text description of the types). Liophis ingeri (Chimanta Tepui) agrees with L. trebbaui and not with L. torrenicola in having an extensively black-marked venter that is as much cross-banded as checkered (fig. 31), but L. ingeri differs from both L. torrenicola and L. trebbaui in having posterior head plates and anterior body scales vaguely pale spotted or reticulated (fig. 30, and Roze, 1958b).|
|Etymology||The species name, a noun in apposition, is derived from the Latin torrens (a swift or violent stream) + connective -i + the suffix -cola (inhabitant).|
