Etymology: Akysis: Derived from Greek, a = without + Greek, kysthos = bladder (Ref. 45335); varius: The specific name is derived from the Latin varius (variable), in allusion to the highly variable number of serrae on the posterior edge of the pectoral spine.

ການຈະເລີນເຕັມໄວ: Lm ?  range ? - ? cm
Max length : 4.0 cm SL ຕົວຜູ້/ບໍ່ມີເພດ; (Ref. 30857)
ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 5 - 6; ຄີກົ້ນຂອງປາ: 8 - 10; ສັດທີ່ມີກະດູກສັນຫຼັງ: 31 - 33. Distinguished from all its congeners by the following unique combination of characters: truncate caudal fin; length of caudal peduncle 16.1-19.8% SL; depth of caudal peduncle 6.5-9.3% SL; length of adipose-fin base 25.6-29.5% SL; interorbital distance 42-46% HL; eye diameter 13-20% HL; length of nasal barbel 44-66% HL; straight lateral margins of the head when viewed dorsally; and 0-5 serrae on the posterior edge of the pectoral spine (Ref. 30226).
Body shape (shape guide): elongated.
Hides in decomposing vegetation in stream beds, where it apparently feeds on zooplankton and rotifers (Ref. 30226).
