Elevation up to 1,628 m.

Type locality: Peru (Dep. Madre de Dios fide Walker 1945)  
TypesHolotype: FMNH 40071
Holotype: AMNH 36020, collected by J. Steinbach [bolivianus] 
DiagnosisDiagnosis: It is a Tachymenis differing from members of the peruviana complex primarily in its more attenuate body proportions. This results in a greater number of caudals and total ventrals, and in a greater ratio of tail length to total length. Other differences can be found in the condition of the hemipenis, and in the dentition. All of these have been discussed in the introduction. This race differs from bolitiana, to be described, in having a slightly lower number of solid maxillary teeth (12-14 as opposed to 14-16), and of abdominals and caudals (in males 148-150 and 60-64 as opposed to 152 and 69), and in having a speckled instead of a checkered color pattern (Walker 1945: 24). 

Distribution: This species has been reported from Peru, but without specific locality (T. Doan, pers. comm. 30 Apr 2012). See Trevine et al. 2022: Appendix 3 for corrections of distribution records.
