Diagnosis.

The female of this new species resembles that of G. bifurcatum Irfan, Zhang & Peng, 2022 in having a similar morphology of the epigyne (Fig. 6 A, B View Figure 6 ; Irfan et al. 2022, fig. 115 A – C), but can be differentiated by (1) ventral plate well-developed (Fig. 6 A View Figure 6 ; vs. reduced); (2) copulatory ducts C-shaped (Fig. 6 B View Figure 6 ; vs. forming a wave-like loop); and (3) dorsal plate slightly covered by ventral plate (Fig. 6 A, B View Figure 6 ; vs. almost not covered).
