Relevant Information:

Description: Dorsal soft rays (total): 8-9; Anal soft rays: 6 - 8. Ituglanis australis can be diagnosed from all its congeners, with the exception of Ituglanis parahybae and Ituglanis cahyensis, by its colour pattern consisting of three well-defined dark brown stripes running along each body flank (vs. dark pigmentation either absent, uniform or forming regular or irregular spots). It can be distinguished from I. parahybae and I. cahyensis in having i,4 pelvic-fin rays (vs. i,3 when pelvic fin is present), modally i,5 pectoral-finrays (vs. i,4) and pores i1 and i3 of the infraorbital branch of the cephalic laterosensory system usually present (vs. pores i1 and i3 always absent). It further differs from I. parahybae by having pores s3 and s6 of the supraorbital branch of the cephalic laterosensory system (vs. pores s3 and s6 absent) and from I. cahyensis by having 8 basal radials of the dorsal fin (vs. 7) Aquarium Care: Even although this species is termed, along with other members of this family, as parasitic catfishes it is well behaved in the aquarium but is seldom seen until feeding time. Provide caves/pipes for this species. Etymology: From the Latin adjective "australis", meaning southern, in reference to the new species representing the southernmost record of Ituglanis.
