Treatment

Xixuthrus microcerus ( White, 1853) View in CoL

( Figs. 13 View Figure 13 J–M, 15C View Figure 15 , 15R View Figure 15 , 18C View Figure 18 )

Macrotoma microcera White, 1853: 40 View in CoL . TL: Java. Holoype in BNHM (examined).

Xixuthrus nycticorax Thomson, 1877b: 154 View in CoL . Marazzi et al. 2006. TL: Australia. Holotype in MNHN (examined).

Xixuthrus microcerus nycticorax: Lameere, 1912:156 View in CoL ; Lameere, 1919: 172; McKeown, 1947: 12.

Diagnosis. The Australian species can be easily separated from other Australian Prioninae in having entire body setose, the protibia with single spur apically and with random spines not arranged in rows.

Types. Macrotoma microcera White , Holotype male in BNHM ( BNHM-010799863 ), with the following labels “ M. microcera , n.s., Java | Macrotoma microcera White Type | 49-5”.

Xixuthrus nycticorax Thomson , Holotype male in MNHN, with the following labels “nycticorax, Type, An. Fr. 1877, Bull. 226, Thoms., Austral. | Th. TYPE”.

Molecular data. BioSample ID: SAMN11080883.

Remarks. X. microcerus was originally described from Java but is widely distributed in the Australo- Pacific region and the taxonomic statuses of many isular populations have always been problematic. While treating the region Lameere (1912, 1919) recognised 5 allopatric sub-species X. microcerus , and further three separate species as X. heros ( Fiji) , X. ganglbaueri ( Fiji) and X. costatus ( Papua New Guinea). Marazzi et al. (2006) and Titarenko and Zubov (2018) reinstated many subspecies and local populations as valid species, but these actions cannot be assessed without molecular data that is currently not available. However, examination of the types revealed no major morphological differences between Macrotoma microcera White, 1853 and Xixuthrus nycticorax Thomson, 1877 , and following Lameere (1912, 1919) we recognise only single species, Xixuthrus microcerus in the Australian fauna. We generated a complete mitochondrial genome sequences for the Australian specimen, but without sequences from other taxa/populations to compare with, no further conclusion can be made here.
