Comments. The above collection records were vouchers from Beaulieu et al. (2010); we also examined the specimens deposited in the Queensland Museum (including those from the University of Queensland Insect Collection), which includes the holotype, and the female reported by Seeman (2007). The original description did not illustrate the dorsum, which is provided here ( Fig. 15 ) to provide diagnostic information on the position of setae, form of the protuberance P -s5, presence/absence of protuberances P -s4 and P -s6, and amount of ornamentation. Two forms of pores are also apparent in H. callimaulos , a larger, more obvious type, of which there are 12 pairs, and a smaller type of which there are ten pairs ( Fig. 15 ).
