Key to the species of the subgenus Xizicus (Paraxizicus)

1 Posterior margin of male tenth abdominal tergite with a pair of dorso-ventrally expanded processes, apex of each process divided into two slightly compressed branches; subapex of lateral margins male subgenital plate with a pair of spines........................................................................... Xizicus (Paraxizicus) furcistylus sp. nov.

- Posterior margin of male tenth abdominal tergite with a pair of unbranched processes; apical area of male subgenital plate with 1–2 pairs of spines..................................................................................... 2

2 Bases of male cerci with 1 quadrate lobe under ventral surface separately; female subgenital plate nearly triangular, posterior margin with a small notch.......................................................... Xizicus (Paraxizicus) fallax

- Bases of male cerci without quadrate lobe under ventral surface; female subgenital plate not triangular.................. 3

3 Posterior processes of male tenth abdominal tergite long, apices slightly inflated, middle area with ventral lobes; apical half of male cerci with a short and wide dorsal branch and a rather long ventral branch; basal area of female subgential plate narrow, the middle concave; apical area broad, posterior margin with a U-shaped notch........... Xizicus (Paraxizicus) anisocercus

- Posterior processes of male tenth abdominal tergite short and directing outwards, without ventral lobe; apical half of male cerci with a long and wide dorsal branch and narrow ventral branch; basal and apical areas of female subgential plate almost equally wide, posterior margin with a rectangular notch.................................... Xizicus (Paraxizicus) biprocerus
