Original description
Muma, 1963: 3-4, figs 7-9 (as Therobates flexacus):

maleS: Total length, 20.0 mm to 21.0 mm.

                            LENGTH         WIDTH
Chelicerae         4.8-4.8 mm      2.0-2.0 mm.
Propeltidium    2.4-2.4              3.4-3.4
Palpi                   18.0-18.0

4th legs              25.0-25.0 


         Holotype smaller specimen
        Coloration and markings almost identical to those of T. arcus Muma except the dusky area on the leg femora covers the apical two-thirds of the segment.
        Dentition of the same general type as that of arcus except the fixed finger is slender, needle-like and strongly S-shaped; the movable finger is provided with a strong principal tooth, two tiny intermediate teeth and an aborted anterior tooth but no mesal tooth; the fondal notch is shallow, bears no denticules and is three times the width of the fixed finger at the base (Figure 7).
        The mesoventral groove of the fixed finger is a narrow slot that extends nearly to the base of the finger where it expands into a cup-like hollow.  Flagellum complex with basal, dorsal tubular bristles slightly S-shaped and plumose bristles strongly S-shaped covering basal half of mesoventral groove.
      
Structure similar to that of T. arcus, except that the propeltidium is wider than long by a ratio of 1 to 1.4, the palpal scopula is composed of about 50 papillae on the tibia and 15 on the metatarsus (Figure 9), and there are only two slender ctenidia on the first post-spiracular abdominal sternite (Figure 8).
