South America: Rio Tocantins, various locations within the Amazon basin, and the southern and southwestern portions of the Rio Orinoco basin. Reports of T. quadrifilis from the Rio Orinoco system are considered herein to refer to T. wallacei, which is the only member of the genus known to occur in this river basin.
南美洲: Rio Tocantins ，亞馬遜河流域裡面的各種不同的地點與 Rio 奧里諾科河流域的南方而西南方部分。 T. quadrifilis 從 Rio 奧里諾科河流域的報告在此被認為指的是 T. wallacei, 是被知道出現在這一個河流域的本屬的唯一成員。

Diagnosis: Distinguished from T. quadrifilis in the alignment of the lateral margins of the head in the region from the anterior margin of the orbit to the posterior limit of the opercle (running approximately in parallel from ventral view vs. diverging laterally, respectively); in the body width at the pectoral-fin insertion as a proportion of the head width at the posterior margin of the orbit (0.99-1.10 vs. 1.17-1.25, respectively); in the distance from the tip of the snout to the anal fin origin (0.29-0.32 of SL vs. 0.33-0.36 of SL, respectively); and in the position of the anterior termination of the gill opening (one orbital diameter posterior of the transverse plane running through the posterior margin of the orbit vs. positioned in the transverse plane running through the center of the orbit, respectively) (Ref. 56964).
鑑別: 在鰓蓋的眼窩到後面的限制的區域從前緣中的頭部的側面邊緣的對準中與 T. quadrifilis 區分了;(大約跑在平行的從腹面看上去 vs. 分開側面地, 分別地) 在身體寬度方面在胸鰭嵌入在眼窩的後面的邊緣作為一個頭部寬度的比例;(0.99-1.10 vs.1.17-1.25, 分別地) 在遙遠之處從吻尖到臀鰭起源;(SL 中的 0.29-0.32 和 SL 中的 0.33-0.36 比較, 分別地) 而且在鰓裂 (一眼窩的直徑 vs. 放置在穿過眼窩的中心橫斷面穿過眼窩的後面邊緣橫斷面後面, 分別地) 的前端的位置中.(參考文獻 56964)
