Etymology: Priocharax: Greek, prio = to saw + Greek, charax, -akos = a fish without identification (Ref. 45335); varii: Named for the late Richard P. Vari, one of the most infuential researchers in Neotropical ichthyology of the past 40 years; noun in genitive.
Eponymy: Dr Richard Peter Vari (1949–2016) was a curator of fish at the Smithsonian. [...] (Ref. 128868), visit book page.

Short description
ຕົວທີ່ໃຊ້ໃນການຈຳແນກຊະນິດ | ສະລີລະວິທະຍາ | ການວັດແທກຮູບຮ່າງລັກສະນະພາຍນອກຂອງດິນ,ສັດ,ປາ…
ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 9; ຄີກົ້ນຂອງປາ: 18 - 25; ສັດທີ່ມີກະດູກສັນຫຼັງ: 33. This species is distinguished from its congeners by the presence of an adipose fin (vs. absence); differs further from P. ariel and P. pygmaeus by the pelvic-fin rays i,6 with i,5 rare (vs. i,5); postcleithra 2 present (vs absent); differs further from P. ariel by having a shorter caudal peduncle 14-18 % SL (vs. 18- 24 % SL) (Ref. 128819).
Specimens were collected between 14:00 and 17:00 in a small tributary of the Rio Jamari, close to a bush of submerged macrophytes in a slow flowing part of the Rio Preto, approximately 200 m above rapids. It was collected with Apistogramma resticulosa, Axelrodia lindeae, Axelrodia stigmatias, Hemigrammus bellottii, Hyphessobrycon aff. sweglesi, Leporinus sp., Nannostomus trifasciatus, Odontocharacidium aphanes and Satanoperca sp. Three of these species are considered miniature: the characids Axelrodia lindeae, A. stigmatias and the crenuchid Odontocharacidium aphanes. This species and the three miniatures are mostly transparent, and with the larger Hemigrammus bellottii which has a predominantly translucent body in life, an ‘almost invisible league’ for the Rio Negro was proposed by Carvalho et al., 2006 (Ref. 128847 in Ref. 128819).
