DiagnosisDIAGNOSIS. “T. hypogia is a member of the ruficauda group which is composed of the Philippine species T. canlaonensis, T. luzonensis, T. rubra, and T. ruficauda. Only one extralimital species, T. kraali of the Kei Islands off the southwest coast of New Guinea, has been definitely referred to the group. The new species differs from T. canlaonensis. T. rubra, and T. ruficauda in having the preocular in contact with the second and third supralabials (in contact with the third supralabial only, in the three above species), and in having 24 scale rows around the mid-body (30 in canlaonensis, 26 in rubra, and 30 in ruficauda). T. hypogia may be distinguished from T. luzonensis by the number of rows of midbody scales (hypogia with 24 versus luzonensis with 20), and the nature of the nasal division (hypogia with incompletely divided nasals versus completely divided nasals in luzonensis). T. kraali differs from the new form principally in having the preocular in contact with only the third supralabial.” (Savage 1950: 52).
