Austranillus macleayi (Lea, 1906) Diagnosis. Genus of the " Illaphanus phyletic series" (sensu Giachino 2005 ), with species characterised by: absence of longitudinal elytral grooves, pronotum with basal border wider than anterior border and denticulate sides before basal angles, elytral disc with two setae, 8th pore of the umbilicate series after the 9th (sensu Giachino and Vailati 2011 ), labium toothless, median lobe of the aedeagus long and weakly curved, and parameres very long and slender. Note. In the original description of the genus Giachino (2005) does not mention the forward position of the 9th pore of the umbilicate series. The omission was due to the lost seta corresponding to the 9th pore, and to the extended length of secondary setae (1st, 3rd, 4th, 5th, 7th, and 8th) in A. macleayi . The study of the umbilicate series of A. jinayrianus sp. nov. indicates, according to Giachino and Vailati (2011) that the 8th pore is actually placed backwards in respect to the 9th. Species included. Currently, two species belong to this genus: Austranillus macleayi (Lea, 1906) Austranillus jinayrianus sp. nov. Figures 36, 37.
