Remarks

Pareucamptonyx zulianus resembles P. townesi as the antenna has the 8 th flagellomere whitish and the mesoscutum without lateral pointed apophyses ( Fig. 4D–E ). However, P. zulianus differs by the presence of a frontal line and the inner margin of 5 th protarsomere with 16–20 lamellae ( Olmi & Virla 2014: fig. 215c–d).
